Stanford Scientists Create a New Energy Source: Paper Batteries
Research published in the Proceedings of the National Academy of Sciences noted that “taking advantage of the mature paper technology, low cost, light and high-performance energy-storage are realized by using conductive paper as current collectors and electrodes”.
SopoLite: New Version of Google Maps to Maximize Sun's Energy
The unit's most interesting facet is its original purpose - collecting data on the solar power potential of wherever its located. Kimura, CEO of Sopogy, plans to park these units all over the country and build out a map of the potential availability of thermal solar energy, or the energy derived from the sun's heat. Such a map will make it much easier to determine the true thermal solar power potential of any given location without having to deploy sensors and testing gear. This could prove to be a boon to the still nascent rooftop and commercial solar thermal power segment.
Figuring out how well solar thermal power works in any given location, however, is somewhat tricky. Micro-weather patterns are very important for solar thermal as clouds can really put a drag on thermal heat collection. Winds and thermal patterns can also reduce solar collection possibilities. That's where Kimura hopes to insert SopoLite, and in the process turn the unit (which can be towed behind a trailer) into a data-collection initiative similar in nature to those funny Google cars you see driving around with spinning cameras mounted on their roofs.
It's way too early to see whether this will take off, but it's a fascinating idea in a small package.
New Failure-Proof Wind Turbine Technology
It is expensive and hazardous sending workers out to off-shore wind farms for repairs when there is a mechanical failure. By reducing the weight, the researchers reduce mechanical failures, caused by the sheer stresses in these very large turbines.
Their technology substituted a “C” shaped core generator (initially in a 20 kW prototype) to test to see if by changing the mechanical structure of the generator they could still maintain rigidity and structural integrity while cutting the weight by more than half.
The researchers have formed NGenTec; a spin-off company, with the help of Derek Douglas, an entrepreneur familiar with raising money for start-ups.NGenTec hopes to raise £4 million to demonstrate that their improvement will also work full scale; at the 6MW level, and then a further £10 million to set up an assembly and manufacturing operation. The technology would reduce costs for both land-based and off-shore wind farms, while having a more marked effect on repair costs of hard to-get-to locations.
Solar-coal Electric System - A New Solar Thermal Hybrid Technology
The 245-megawatt Escalante Generating Station in Prewitt, N.M., 27 miles northwest of Grants, is one of two host sites that California’s Electric Power Research Institute (EPRI) chose to test the technology. The other site is a natural gas-powered generating station near Las Vegas, Nevada.
Solar thermal hybrid applications can provide a low-cost option for incorporating renewable energy into established grids because, rather than build new transmission capability for a stand-alone solar concentrating plant, the steam generated will make electricity through the turbine generator already established at the coal facility.
It also eliminates the challenges of siting a new plant and new power block, said EPRI Vice President of Generation Carolyn Shockley in a news release.
Solarmer Energy Attained 7.9% Efficiency with Plastic Solar Cells
The aperture-area test results also mean the company has beat its own 7.6 percent cell efficiencies, certified by the Newport Technology & Applications Center’s Photovoltaic Lab in October.
The company said it uses low-cost plastic as the active materials to convert solar energy into electricity. The active plastics layer is very thin, also offering low costs. The company said it also uses low-cost printing techniques and a fabrication process that has low temperatures and is eco-friendly.
Solarmer is currently completing its pilot manufacturing line and has said its plastic solar panels are expected to be available in 2010.
South Korean Engineers Develop New Solar Cell Material
Global demand for the CZT compound is on the rise since it can be used to make radiation sensors to detect cancer growth, space telescopes, and solar energy cells.
The global market related to various sensors using radiation stands at around US$1.1 billion and is expected to grow 10 percent annually in the near future. Of the total, CZT sensors make up US$30 million, although it is growing at a faster pace compared to other arrays.
A New Solid Catalyst to Reduce Costs of Biodiesel Process
The T300 heterogeneous catalyst is nontoxic and can be a direct replacement for conventional catalysts used in biodiesel production. The drop-in solid catalyst operates at industry standard pressures and temperatures and is removed with filtration. As a result, current producers can retrofit their plants in a matter of days at very low cost. Another key advantage is that the glycerin coproduct has purity greater than 98 percent and qualifies as technical grade, which significantly enhances its overall value.
Catilin is commercializing the research done in developing the new catalyst at Iowa State University in Ames and the U.S. DOE’s Ames Laboratory.
Dow's New Solar Energy Technology Wins Accolades
Dow Chemical, the Powerhouse Solar Shingle's inventor, will make the shingles commercially available by the middle of next year. The Powerhouse design includes thin-film cells of copper indium gallium diselenide. Dow notes the cells' low cost relative to other solar technologies.
And, on top of low cost, Dow's new shingle has other advantages. The company reports that the installation process is no different than that of traditional shingles, making Powerhouse shingles attractive to contractors. And in addition to saving money for homeowners by cutting energy use, the shingles are anticipated to make a lot of money for Dow - up to $10 billion a year by 2020.
Scientists Make Foldable 3D Solar Cells around an Optical Fibre
According to team-leader Professor Zhong Lin Wang, “Using this technology, we can make photovoltaic generators that are foldable, concealed and mobile. Optical fibre could conduct sunlight into a building’s walls where the nanostructures would convert it to electricity. This is truly a three dimensional solar cell.”
The dye-sensitised nano-converter is based on coated zinc oxide structures grown on the optical fibre, from which the cladding has been removed, covered with a conductive layer and seeded with ZnO.
The next step is to grow a series of aligned zinc nanowires around the fibre from solution, resulting in something closely akin to a bottle brush, before coating the wires with dye and immersing them in a liquid electrolyte to complete the circuit. The team claim that the set up achieves a solar efficiency of 3.3%.
Researchers Claim Lithium-ion Battery Breakthrough
According to Stefan Koller, a researcher at TU Graz, the gel was designed for use with lithium-ion batteries and with the silicon gel it's possible to store 10 times more [power] per weight than graphite.
Koller said that to produce the gel his team had taken a hydrated silicon compound, irradiated it with ultraviolet light, and heated it to form an amorphous silicon gel. However, the problem with using silicon gel as a substrate is that it expands and contracts by up to 300 percent during uptake and transfer of lithium ions. Koller said his team had overcome this by using graphite as a buffer material.
WaveRoller : An Invention to Harness Underwater Wave Energy
Each one at full size weighs 20 tons and produces 300 KW.Each 20 ton WaveRoller “door” can be connected together in threes to make up a nearly 1 MW unit. Obviously you can make a modular farm of any size under the ocean of these three-packed units, so the output can be as much as you can build tons-worth of “doors”.
AW-Energy’s WaveRoller uses the roiling currents under the sea to make energy from the repetitive surge motion at the sea floor in what Koivusaari calls the surge zone. The kinetic energy produced is collected by a piston pump. This energy can be converted to electricity by a closed hydraulic system in combination with a hydraulic motor/generator system.This year the company will get the results of a full scale demo built off the coast of Portugal.
New Energy Efficient Flow Control Systems for Hydro Power Plants
The dynamic seal ring pointing device was awarded an invention patent, it is used in the inlet valve of hydro power plant. NF Energy’s propriety valve pointing devise has distinct advantages, it provides warning signals, which can be timely sent out with clear instructions. Long term stability of seal ring is achieved through the reduced number of parts. Additionally, the valve pointing device provides greater efficiency, according to NF Energy it saves hydro power due to its easier operation in maintenance, adjustment and replacement of equipment. The valve’s smaller resistance is achieved by optimizing structure.
The butterfly plate adjusting device, is used in the large dimension vertical butterfly valve, the propriety device was awarded a new application patent. It is effective in the reduction of friction and the subsequent wear and tear of bottom valve shaft. The adjusting device is also effective in the prevention of internal leakage. As a result the product achieves energy savings and an extension to the valve's operational life.
Eternal Candle : A Renewable Solar Heat Storage Technology
The research team led by Anthony Robinson invented a white light-emitting diode (WLED) lantern, powered by the sun. At night, the device converts the stored heat into electricity, which drives the WLED. The lamp doesn’t require batteries or have any running costs, but it’s not exactly eternal. The device is designed to provide light for four to five hours.The technology is best suited for off-grid communities, so the likes of sub-Saharan Africa, China and some parts of India where people don’t have electricity coming into their homes.

Algae-Based Bioplastics Could Replace Petroleum-Based Plastics?
Cereplast algae-based resins could replace 50% or more of the petroleum content used in traditional plastic resins. Currently, Cereplast is using renewable material such as starches from corn, tapioca, wheat and potatoes and Ingeo PLA. Cereplast has initiated contact with several companies that plan to use algae to minimize the CO2 and NOX gases from polluting smoke-stack environments. Algae from a typical photo-bioreactor is harvested daily and may be treated as biomass, which can be used as biofuel or as a raw material source for biopolymer
feed stock. The company is also in direct communication with potential chemical conversion companies that could convert the algae biomass into viable monomers for further conversion into potential biopolymers.
Kite Power Harnesses Unspooling Motion For Energy
Instead of harnessing wind power to turn blades tethered to a pole, the KiteGen simply harnesses that rapid unspooling motion of kites reeling out as they release upwards. So instead of a heavy static structure this is simply a light and flexible kite.
The KiteGen would hover at 2,600 feet to produce power each time the kite’s tether unspools, spinning an alternator that generates the power. When the cables are completely unwound the production phase ends, the cables are reeled in to start another production phase. The cycle repeats; like in a yo-yo in reverse.
So the KiteGen splits the components of wind power. In the air; nothing but high efficiency air foils. On the ground, all the heavy machinery for power generation. Connecting the two; high resistance lines transmitting the traction of the kite.
The company holds more than 20 international patents and plans a demo by the end of 2010. These guys are thinking out of the box. They point out that there is about a GW of wind potential in the unusable no-fly air space around nuclear power plants. They suggest that’s the perfect spot for their 2,600 foot kite.
MIT Roof Tiles Save Energy in All Climates
In cold weather, the polymer stays dissolved and the black backing shows through, but exposed to heat, tiny droplets form and scatter the light back to produce a white appearance. The tiles reflected 80% of the sunlight falling on them when white, and only 30% when black.
The cooling needs would then be reduced 20%.
Dark-roofed houses absorb more heat, requiring more air conditioning use in the summer for cooling, which in turn means using more energy for running air conditioners, which emits more greenhouse gases. Steven Chu at the DOE famously recommends “cool” white roofing for the sunny states - mentioning California, Florida and Georgia. Cool roofs reduce energy costs associated with air conditioning.
There are already special energy efficient elastomeric roof paints, rated by the independent cool roof council through coolroofs.org for how well each one reflects heat. California Energy Commissioner Athur Rosenfeld probably originated the idea to use “white roofs” for sunny climates, where air conditioning costs outpace heating costs for energy use.
In summer, the white roofed house is reflecting heat away. lowering energy costs. But for climates that get both extremes of heat and cold winters, there has not been a solution till now. Their carbon emitting energy use goes up summer and winter.

Propulsion System for Mobile Offshore Wind Farm Ship
Weighing over 80 tons and measuring approximately 8m high, the Voith Radial Propellers will enable the specialised vessel to sail at approximately 10 knots with a full load. The propeller’s 360 degree steering will allow highly accurate positioning even in difficult sea conditions for a vessel which has a design resembling that of a drilling platform.European construction giant STRABAG SE, which employs 76,000 people and had a turnover of €13.7bn last year, has ordered five such Voith Radial Propellers for the vessel.
The groundbreaking for a trial gravity foundation for offshore wind farms took place in Cuxhaven last week. The project is a step toward the realisation of planned wind farms in the North Sea.Completion of the trial gravity foundation is planned for spring 2010. Series production is scheduled to begin in autumn of next year. Starting in 2011, the first wind turbines for the offshore wind power plant GlobalTech I are to be set up from Cuxhaven.
Nanomaterials to Boost the Efficiency of Geothermal Energy Production
In conventional geothermal use for power production, hot rock beneath the earth's surface needs to heat water driven into it to 300 degrees Fahrenheit, or more typically hotter, to make electricity production efficient. That hot rock might be found 5,000 feet beneath the ground's surface in a few places, but typically it's much, much deeper.
Heat from the ground is typically extracted by forcing water into the ground and then pumping it up after it's flowed through rock and picked up heat. It then goes through a heat exchanger to heat liquid to produce vapor to drive a turbine. If it's water that's being used as a liquid, it has to be 212 degrees at sea level to produce steam.The traditional geothermal energy production methods are inherently inefficient in the way they remove the heat.
The nanomaterials called "metal organic heat carriers"with particles one-thousandth the width of a human hair can hold onto gas molecules at a much higher temperature, preventing the fluid from flashing to gas in the heat exchanger until it gets to a higher temperature and pressure. If successful, enhanced geothermal systems like this could become an important energy source.
WindAir -A New Renewable Energy Invention
The WindAir system uses the warm air flow from the exhaust of a traditional air conditioning unit and drives it into a secondary fan turbine system. This secondary system has an electric-generating mechanism that transforms the wind flow into free, clean, renewable energy which is then inverted into the electric meter of the home or office building. This renewable energy has the capability to reduce the increase in electric used by the air conditioning system by generating enough electricity to send it back to the meter, thereby turning the air conditioning unit into an actual "sub-power station".The unique WindAir converter system can be incorporated into any existing air conditioning condenser unit or manufactured as a complete new unit.
Nanotechnology for High Efficient Solar Cells
The key to the process is use of a chemical bath, controlled by a microreactor, to place thin-film deposits on various substrates such as glass, plastic, silicon or aluminum. In this case, the technology will create a type of nanostructure that resembles millions of tiny pyramids in a small space, which function to reduce the reflectance of any light that strikes the material.
The films reduce the reflectance of light, and in the case of eyeglasses would capture more light, reduce glare and also reduce exposure to ultraviolet light. Some coatings with these features are already available, but the new technology should perform better at a lower cost, and be able to be applied on-site in a dispenser’s office.
Electricity from the Artificial Fluorescent Lighting
New Energy’s solar cells in their transparent SolarWindow™ generate electricity by using the visible light in artificial fluorescent lighting typically installed in offices and commercial buildings. In tests published in the Journal of Renewable and Sustainable Energy they outperformed regular solar cells by orders of magnitude; producing two to ten-fold more power.
Researchers tested the ultra-small solar cells on a 1”x1” substrate against today’s popular solar materials for their capacity to produce electricity under varying artificial light conditions, mimicking the levels of light exposure in homes and commercial offices.
Under normal office lighting conditions, without any natural light from windows, New Energy’s ultra-small solar cells produced not just twice the power of monocrystalline silicon, but achieved:
1. 8-fold greater output power density than copper-indium-selenide, known for its high optical absorption coefficients and versatile optical and electrical characteristics.
2. 10-fold greater output power density than flexible thin-film amorphous-silicon.
PecoBOO - An Eco-screen to Save Computer Energy
New Invention to Cut Greenhouse Gas Emissions
Details of the invention are being kept under wraps until an official launch later this year.However, Dan Chester, a former semiconductor industry entrepreneur who was brought in to spearhead Iceotope's development, did reveal that it involves using liquid to cool the server racks.The data centre servers are currently cooled by using large scale air conditioning plants to chill the hot air they generate – further increasing the data centre's carbon footprint.Liquid cooling would not only be more energy efficient, it would also keep the servers cooler, extending their life span.
Solar-Powered Recharger from An Altoids Tin
Kelty got the idea for the solar-powered charger from the Minty Boost, a $20 charger powered by two AA alkaline batteries. It’s called the Minty Boost because it is also housed in an Altoids breath mints tin. But it had its shortcomings.To improve upon the Minty Boost, Kelty replaced the AA batteries with a rechargeable lithium polymer battery and added a small solar panel. The solar panel recharges the internal battery, which in turn recharges the iPhone.
If everyone who owned the 30 million iPods and iPhones sold to date worldwide recharged their gadgets every day with solar power, instead of plugging into an outlet, 30 million pounds of carbon dioxide, the leading cause of global warming, would not be created.
New Powerful Laser System Could Create Fusion Energy from Waste?
The NIF team will fire nearly 200 individual laser beams generated by an accelerator the size of a football field. The beams converge on a single target chamber containing a capsule of hydrogen. The hope is to compress it, and creating a subatomic reaction called fusion, ultimately igniting a controlled version of the same thermo-nuclear combustion that takes place on the sun.
As hydrogen is compressed, it releases particles called neutrons, which can penetrate the nucleus of another atom. So now we could take nuclear waste and use those neutrons to bust it up, get energy and remove the waste.

OIT Students Look At Ways to Clean Waste Vegetable Oil into Fuel
However, the project is in the early stages, which can produce about 25 gallons of biodiesel at a time. The system separates glycerol from the used vegetable oil in one tank and then further cleanses it in an adjacent tank.The end product would be high-grade biodiesel that meets national American Society for Testing and Materials standards. The energy needed to run the biodiesel reactor would come from solar panels.The advantages of this biodiesel reactor is that it would be far cheaper than others on the market, which cost around $200,000.
Laser Treatment Could Make Plain Light Bulb Much More Efficient
The team developed a laser process that treats the tungsten filament in a traditional bulb. The process creates nano- and micro- level structures on the filament that dramatically improve its efficiency. The process involves an incredibly short femtosecond laser pulse, which lasts only a few quadrillionths of a second.
It’s not immediately clear how long it would take to commercialize the discovery. But it could be relatively simple to implement in a manufacturing environment once refined.Other technologies are also crowding the field. The U.S. Navy is promoting LED and HID lighting in its ships. Cambridge Researchers say they’ve developed a LED bulb that costs $3 and last 60 years. A technology called ESL is headed to market as well. It will be interesting to see if the Rochester process finds a place on store shelves.
Heliotropic Biomimicry: Solar Panels That Follow The Sun
Solar cells that track the sun can be 38 percent more efficient in generating power than fixed solar cells.Instead of using an electronic tracking system, the team decided to use the difference in temperature between shaded and sunny areas to change the properties of the material supporting solor photovoltaic cells.The system, once built, is completely passive, requiring no power source or electronics to control the movement.
After experimenting with different materials and configurations, they came up with a system whereby solar panels would be placed on top of a curved arch made of a pair of metals, such as aluminum and steel.The concept was demonstrated by shining a spotlight on one side of a bridge containing a solar panel. The heat from the light causes the bridge to arch, tilting the panel towards the light.
Solar Cells Along Highways To Generate Power
A Novel Way of Recovering Energy from Flowing Water
In order to enhance the oscillating foil idea, Upton has added a Kenape turbine in front of the oscillating foil. A Kenape turbine is an invention of Ken Upton's that essentially consists of a series of tethered kites that are forced to circle. For use in water, the flexible blades of the Kenape rotor are made bat wing shaped. As well as allowing the extraction of some energy from the flow from the rotation, the wakes of the bat wing elements generate considerable amounts of turbulence to enhance the oscillations of the wing.
In addition to this, Upton's foil shape is a delta wing, with a guiding canard wing at the front, so as to adjust the angle of attack and guide the foil into an attitude that generates maximum flutter.Upton's prototype is only a working model, with the Kenape elements made out of old XRay film, which he says combine the required elements of strength and flexibility.It may have potential of its own as a low cost turbine.
Optiwind : A Small But Powerful Wind Turbine?
The Optiwind comes in two models. The first can generate 150 kilowatt and can be used by buildings that spend up to $35,000 a year in electricity while the bigger model can generate up to 300 kilowatt and can be used in conditions that normally would require about $75,000 a year in electricity money.
Eventhough it is an ideal turbine that can be used by schools, hospitals and hotels, according to local zoning laws, we need about 3.5 acres of open land available to get an authorization for the Optiwind. Another problem with this turbine is it generates some noise compared to other turbines.
New Solar Energy Collector with High Efficiency
Ron Segev, founder and CEO of Zenith Solor was quoted as saying that the new solar collection device will be able to collect and produce thermal as well as electrical energy at the same time.The new collecting dish device will be able get at least 50% more energy from it in the form of hot water, which is derived from water used to cool the device.Once the device is in operation, it will only require maintenance costs since no fuel is needed. It will also work in places where less sunlight is normally available.
Vibration-Power Generators Turn Road Traffic into Electricity?
For the time being, though, that LED light shines because it is connected to 10 generators set beneath the roadbed of the Metropolitan Expressway crossing the bridge, where vehicles' vibrations make the pendulums in the generators swing and so generate electricity.
After many failed trials with various materials, Kouhei Hayamizu, who invented the vibration-power generators, found that substances called piezoelectric elements - made of barium titanium oxides - generate electricity when pressure is applied to them.

New Solar Panel Produces Energy In the Shade
In direct sunlight, the peel-and-stick panel produced 80 volts or three amps of electricity, which is more than enough to power both the 36 or 48 volts needed for standard golf carts. Mayeaux said his latest invention is the first solar panel to be proven to produce energy in the shade.
The Going Green Solar Panel is made from three layers of amorphous silicon and each layer is tuned to a different level of sunlight frequency. Unlike the glass solar panels, the peel-and-stick panel is durable enough to continue working normally even after being punctured.

Fusion Reactor- Fuel Source From Nuclear Power?
A tokamak is a Russian invention, a kind of fusion reactor using a toroidal magnetic field to confine and accelerate a plasma. The power is generated via the same means as that of the sun. Deuterium and tritium, two radioactive isotopes of hydrogen are fused into helium. Deuterium is abundant in our oceans but tritium is extremely rare on Earth, but can be synthesized from lithium which is readily found in many of Earth's minerals. The result is a fuel source that with research, can be extracted with minimum impact on the environment and while it is not renewable, is abundant enough for at least several hundred million years of power.

Twenty tons of such liquid additives have been used to conduct fuel-burning performance tests at more than ten factories and institutes such as Chongqing Titanium Industry and Beijing Research Institute of Coal Chemistry.Test results show that the new additives improve coal efficiency by 7-12%, reduce sulphur dioxide emissions by 24-33%, and nitrogen oxide emissions by 17%.
Graphene-A Carbon Material to Store Renewable Energy
A New Catalyst For Efficient Hydrogen Fuel
Nature, on the other hand, uses a simple inorganic redox core that self-assembles from water. It's unstable, so plants repair and replace their OECs every 30 minutes or so, and that's what Nocera's artificial OEC does too. Instead of Mn and Ca, it uses Co and Pi, works in sea water, dirty water, or a glass of water, and repairs itself spontaneously!When coupled with more widespread solar panels and more efficient fuel cells, Nocera believes that this CoPi catalyst would provide a household's daily fuel needs from 8 liters of water.

Wave Treader-A Hybrid of Wave and Wind Power
The system, known as the Wave Treader, comprises sponsons, projections from the sides of a watercraft, for protection, stability, or the mounting of equipment, mounted on the end of arms both in front and behind the turbine’s column vertically mounted on the seabed.
Hydraulic cylinders are attached between the arms and an interface structure and as the wave passes along the device the sponsons and arms lift and fall stroking the hydraulic cylinders.The cylinders pressurize hydraulic fluid which, after smoothing by accumulators, spins hydraulic motors and then electric generators. The electricity is exported back to the shore through the same cables used by the wind turbines.
Can Magnet-Driven Motor Replace the Gas & Diesel ?
He says the difference in this motor and others is it actually uses less energy the harder it runs. He and wife Katherine now have 2 patents on the motor, but they're waiting on more independent testing before he takes it to American-based manufacturers. "We'd be able to increase our fuel mileage on gas motors and diesel motors. We could also eliminate the gas or diesel motors and go strictly electric," he contended.

Thin-Film Solar Material Could Charge Portable Devices?
The material, called Power Plastic®, is a lightweight, flexible and inexpensive source of power for portable devices and structures. While Power Plastic® is currently being used in handbags and patio umbrellas to charge portable devices, Konarka hopes to perfect a translucent version of the product within the new few years.
Power Plastic® has several advantages over traditional photovoltaic technology including a higher efficiency at low light levels, the ability to flex to a 2-inch diameter and an extremely low production cost. The flexibility factor means that the solar film can be integrated into new materials such as fabrics.
Rooftop Wind Turbine- A New Invention
The invention meets the "simple" criteria: the 3-foot turbine is made from a motor similar to a blender's, mounts directly onto the roof, and gets plugged into an electrical socket. But instead of drawing electricity, it would generate power and deliver it back to the grid.Maglaque says it won't be enough to power an entire house, but could light a home using high-efficiency bulbs.
Wind Energy From Hot Air Balloons
Edmond’s system works by using solar energy to fill a balloon with hot air. The rising balloon pulls a tether, which turns a generator on the ground. Once the balloon has floated up to 3 kilometers, air is released and it loses buoyancy. The balloon needs less energy to be pulled down and a net power gain is reached as a result.
Ultra-Large Scale Vertical Wind Turbine- Will It Work?
His thought is that a 40 foot baffle will increase output by 1200 percent. If the 40 foot baffle system is successful, that means that 1 turbine and baffle system (about $200,000), would have the same amount of power as 12 turbines without baffles (about $150,000 ), so there’s financial efficiency.Eventually, Fuller wants to build a 120 foot model of his turbine. He estimates that it could produce 30,000 to 75,000 kWh—enough for 30 to 70 homes.
Clean Energy from Slow-moving River Currents
The envision is groups of cylinders in frames on the ocean bed or in streams, perpendicular to currents. As the water flow hits the cylinders, it creates vortices that cause the cylinders to move up and down. That energy drives generators to make electricity, which goes through cables to the electrical grid on land. The size, number and placement of the cylinders depends on the body of water.
Genetically Engineered Reflective Crops to Reduce Global Warming
The researchers’ bio-geoengineering technique could potentially lead to a 2°F drop in temperature across central North America and pieces of Europe and Asia. Existing crops could be used and more reflective crops could also be bred or genetically engineered.While bio-geoengineering won’t put a complete stop to global warming, it is a relatively cheap, simple tool that could at least buy us some time.
WiTricity- Technology for Wireless Electricity
Similar in design to the way wireless hubs allow access to the internet without the need for wires, the PowerBeam could revolutionise the way laptops, music systems and other household electrical items are powered."The optical technology turns electricity into optical power," the creators say."That power is then beamed across open space into a receiver. Similar to a solar cell, the receiver turns the optical power back into electricity. Whatever device is attached to the receiver is powered without any wires."
The technology can currently send about 1.5 watts of power to a solar cell situated 10 metres away and PowerBeam's co-founder David Graham suggests this can be increased without difficulty. An average laptop uses between 30 and 50 watts.Fears have been raised about the health consequences of using wireless technology such as this, but these have been dismissed.
Garbage for Fuel & Construction- Breakthrough in Waste Management
According to one embodiment of the invention, the cellulose and plastic materials are shredded or ground, and then blended together. The blended materials can then be fed to an energy converter, such as a combustion unit or a gasifier, where they are burned as fuel source or used to create synthetic gas.Or the Blended materials are heated or have a binding element added thereto. Such mixture is then compressed to form a desired shape or sized object, and that object can then be packaged, distributed, or used. The blended object can be used as a fuel source, or as a building, sound attenuation, or insulation material.
Basically, slabs made of plastic, either pressed together with fiberglass of metal rods (for resistance), or melted so that the plastic keeps the mixture together, could be used for insulating buildings both thermally and acoustically. If they are reinforced, the slabs could also be used as walls and other high-strain construction elements, and could even be employed as a structure for new edifices.
Alubond SCP Solar Panel-Breakthrough in Solar Energy
The new class of panels doesn't require rivets for its joining corners, which somehow makes it weigh about 4 kilograms per square meter, as opposed to the massive 12.5 kilograms per square meter an average glass-encased panel weighs. Aluminum-based designs are lighter than glass ones, but require large components to fix them, which drastically increase their weight. Rivets make the entire construction lose its reflectivity, and thus decrease efficiency.
Alubond SCP is a 3 mm composite weighing approximately 4 kg per sq m with a 92-per-cent reflectivity. The product’s ability to retain a parabolic shape to precise coordinates, and its lightweight features and innovative rivetless joining process, substantially reduces the substructure costs.
“We hope the success of this project will lead to an upsurge in the development of more solar energy plants, which will not only lessen the strain on existing energy resources, but also severely reduce the pollution levels that are currently witnessed in power generation,” a Mulk spokesman says, commenting on the revolutionary breakthrough.

“The high efficiencies of our solar cells are the most effective way to reduce the electricity generation costs for concentrating PV (photovoltaic) systems,” said Andreas Bett, department head at Fraunhofer ISE. “We want that photovoltaics become competitive with conventional methods of electricity production as soon as possible. With our new efficiency results, we have moved a big step further towards achieving this goal.”
The Fraunhofer system concentrates incoming sunlight by a factor of 454, then focuses the beams onto tiny — 5 millimeters square — solar cells made of gallium indium phosphide and gallium indium arsenide on a germanium substrate.Previously, such so-called “metamorphic multi-junction” solar cells presented efficiency problems because of hard-to-eliminate defects in the solar cell’s crystal materials. Rather than get rid of the defects, the Fraunhofer team found a way to localize the defects in parts of the solar cell that aren’t electrically active. The result: a solar cell whose electrically active regions are free of defects and capable of record-high efficiencies.
Arboform - A Liquid Wood To Replace Plastic
"The cellulose industry separates wood into its three main components -- lignin, cellulose and hemicellulose," ICT team leader Emilia Regina Inone-Kauffmann told DPA.The lignin is not needed in papermaking, however. They mix that lignin with fine natural fibers made of wood, hemp or flax and natural additives such as wax. From this, they produce plastic granulate that can be melted and injection-moulded.The final product can resemble highly polished wood or have a more matted finish and look like the plastic used in most household items.
The German researchers were able to reduce the sulphur content in Arborform by about 90 percent, making it much safer for use in everyday items.Bolstering Arboform's environmental credentials, Eisenreich's team also discovered that the substance was highly recyclable.
Hubless Windmill – A New Wind Energy Invention
Now Sridhar Condoor at Saint Louis University in Missouri has designed a hollow, cylindrical wind turbine that has no central hub. Its tube-like form means the device could be placed around a pre-existing feature such as a chimney stack, cellphone mast or even a tree trunk.The outside of the turbine is a cylinder that is incised with inlets to catch the wind from any direction and toothed on the inside to drive a gear that powers a generator.
A cylindrical frame within allows the main cylinder to rotate freely and can be mounted around another object - either vertically or horizontally. That makes it possible to install without needing clear space, and could even provide a way to hide ugly features, the patent says.
Scots smart meter - weapon in fight to cut carbon emissions
The "smart meter", the brainchild of Scots telecoms engineer Eric Beattie, was originally conceived as using communications equipment to interact with prepayment meters to allow customers to top-up their meter remotely. But,Smart meters currently undergoing consumer trials throughout the UK, are seen as a potentially revolutionary aid to carbon reduction, as they allow householders and businesses to monitor closely in real time how much energy they are currently consuming and at what cost.
As the energy industry faces up to ever-deeper cuts in carbon emissions over the coming decades, the installation of smart meters in customers' homes is becoming increasingly important because of its potential to change consumers' behaviour and reduce energy consumption.In Italy, around 24 million smart meters have already been installed, and France and the Nordic countries are also making "an announcement a month" on the continued roll-out.
Gravity Power: An Addition to Alternative Source of Energy for Fossil Fuels
Rajaram, says that it is "an evolutionary initiative that can possibly free the world of its dependence on fossil fuels, underlying much of the volatile price rise".
Rajaram, former managing director, Konkan Railway, said his technology, unlike other sources of renewable or alternative energy like sunlight or biofuels, would not require heavy investment or land and can work with existing infrastructure even in developing countries.

Mitsubishi, Sumitomo, Spreadable Electronics - Paint-On OLED Harness Solar Power
The molecular soup mixture would have organic light-emitting diode (OLED) and solar cell building blocs that can be spread or even sprayed like paint in an ultra-thin layer that is only 100 nm thick. By combining both technologies, it may be possible to have displays on the market that don't even have to be plugged in but charged using solar panels. The companies even say it could be sprayed onto the back of cell phones to charge up the device.More from here
IBM Uses Magnifying Glass to Boost Solar Output
According to test results, IBM was able to capture 230 watts of energy on just one centime of solar cell which would then be converted to 70 watts of usable electricity. That is FIVE times the usual output of typical PVs. So, if just a small surface area could generate electricity which could power whole structures, for example, this means there'd be a decrease in the needed quantity of photovoltaics, thereby lessening installation costs.More from here
