Hewlett-Packard (HPQ) has built its reputation on printers, PCs and other tech gear. Now it's lending a hand to a much different industry: solar.

HP had a recent announcement that it will license technology it co-developed with Oregon State University to solar startup Xtreme Energetics, which hopes to launch its first products in two years. The HP technology will help grab the sun's rays for solar panels in a way that could generate electricity at twice the efficiency and half the cost of traditional solar panels, the companies say.

General Motors Chairman Rick Wagoner announced Tuesday that his board has given the green light to begin manufacturing the Chevy Volt, an extended-range electric vehicle. He pledged to get the Volt into dealerships by late 2010.That would be earlier than the timetable announced by Nissan Motor CEO Carlos Ghosn, who in mid-May said that Nissan would sell large numbers of electric vehicles to U.S. consumers by 2012 and would offer electric cars for corporate fleets in 2010.

Across GE's production line, work is under way to use new battery technologies to help propel tugboats, power delivery trucks and heavy machinery and even support diesel locomotives.

Lithium-ion batteries, which revolutionized consumer electronics, are being developed to power cars. Not only do they store more energy in smaller spaces, but they also lose their charges slowly. Several carmakers and GE are racing to develop new kinds of lithium-ion batteries for autos.

Scientists at the Lawrence Livermore National Laboratory have revealed that they have driven a car 650 miles on one tank of liquid hydrogen. In a recent test, the team installed a super-insulated hydrogen gas tank in a standard Prius hybrid that was able to keep a full load of the liquid without evaporating for six days, setting a new world record.

The 300-pound tank removes a lot of obstacles to the development of hydrogen-powered cars. Current versions, such as the fleet of hydrogen-electric Toyota Prius’s used by various city governments across Southern California, run on compressed hydrogen gas, and have a limited range of around 80 miles between fill-ups. Even a fairly modest three-gallon tank fills the entire trunk of a Prius, but still only allows a range of around 200 miles, not really enough to compete with gasoline-only vehicles. One way to overcome this limitation is by using liquid hydrogen, which takes up around a third of the volume of compressed gas. However, it is much more difficult to handle, mainly because it must be kept at very low temperatures (around -420oF) and extremely high pressure to prevent it from evaporating as the engine heats up.

Battery company Superlattice Power (until very recently called Hybrid Technologies) has released a new report which makes a few bold claims about its new lithium ion polymer battery.The company claims to have made significant strides through the advent of a new cathode material which uses the “superlattice” structure seen above. The new tech battery will supposedly allow for automotive applications capable of traveling over 200 miles on one charge and operate on the higher than normal voltage range of 4V to 2.3V. If proven to be true those claimed specs would mean a substantial gain over current li-ion batteries which give an effective range of roughly 120 to 140 miles.

Toyota has announced what it claims is a major breakthrough in fuel cell technology, with a new prototype that is capable of more than doubling the range of previous fuel cell vehicles.

The Fuel Cell Hybrid Vehicle – Advanced (or FCHV-Adv) has a range of 510miles on a single 156-litre tank of Hydrogen – the company’s previous-generation FCHV could only extract 205miles from its 148-litre tank. More important, from the point of view of corporate honour, the FCHV-Adv has double the claim range of the Honda FCX Clarity.

The dramatic extension in range has been achieved by improving the performance of the fuel cell, improving regenerative braking which feeds a battery-hybrid system and reducing the amount of power consumed by auxiliary systems.

EMTA Holdings, Inc., an energy, fuel and environmental conservation company, announced recently that the Texas Commission on Environmental Quality ("TCEQ") has re-evaluated the emissions data and determined that Clean Boost LE Diesel Fuel Treatment does meet the state's stringent low-emission diesel fuel regulations. Clean Boost LE Diesel Fuel Treatment is produced by White Sands, LLC, a wholly owned subsidiary of EMTA Holdings.

Tests conducted in the past by the independent nonprofit research institute in San Antonio, Texas, demonstrated that the Clean Boost LE Diesel Fuel Treatment additive reduces nitrous-oxide (NOx) emissions and particulate matter (black smoke) to levels that bring diesel-powered vehicles into compliance with the regulations of the TCEQ -- without impacting fuel economy. The testing was observed and approved by the U.S. Environmental Protection Agency (EPA), which is considering extending the strict clean air regulations in Texas to the rest of the nation.

Webasto Product North America, a global leader in heating and cooling solutions for the light and heavy-duty transportation industries, has received California's Air Resources Board (CARB) approval for its BlueCool Truck Bunk Cooler. Out of all CARB approved devices, BlueCool Truck (BCT) is the only engine-off technology that has no emissions when in use.

BlueCool Truck's source of cooling is a high-tech cold storage unit that is charged (frozen) while the truck is running. During times of driver rest, the system utilizes only small amounts of electricity from the existing vehicle batteries (no additional batteries are needed) to circulate super-chilled coolant between the cold storage unit and a heat exchanger installed in the truck sleeper cabin. Once charged, the system uses no diesel fuel and therefore produces no emissions during the cooling operation because it runs independently of the OEM air conditioning system.

The principle behind how BlueCool Truck works is not a new discovery, it is a natural phenomenon called latent heat. It has been known for centuries that ice has poor thermal conductivity and extracting cold storage efficiently and effectively is extremely difficult. This problem has been overcome now by embedding the water/ice in a high-tech graphite matrix, with a resulting thermal conductivity that is 100 times better than a pure water/ice exchange. The design provides a highly efficient, compact and dynamic thermal energy storage system that produces an assured cooling output at a constant temperature.

One of the most promising new ideas in energy efficiency comes from researchers at the Massachusetts Institute of Technology. The proposition: get more power and efficiency out of turbocharged motors by injecting ethanol, methanol or E85 (85 percent methanol, 15 percent gasoline) into the engine at times of higher demands for power.

The MIT crowd claims this technology can boost gas mileage by as much as 30 percent, and that it allows a high-compression engine and high-boost turbocharger to operate on regular gasoline. Daniel Cohn, senior research scientist at the MIT Laboratory for Energy and the Environment, and other MIT professors, have formed a company, Ethanol Boosting Systems, and are testing their concept with Ford Motor.

On another front, Daimler and General Motors are experimenting with motors that run on gasoline but combine features of traditional gasoline engines (fuel ignited by a spark) and diesel technology (fuel ignited by compression of fuel and air).

Researchers have made a breakthrough in the development of "green gasoline," a liquid identical to standard gasoline in energy contant yet created from sustainable biomass sources like switchgrass and poplar trees. The discovery could transform the renewable fuel economy by eliminating the need to grow corn for ethanol and rescue America from importing expensive and dwindling foreign oil supplies.

The latest pathways to produce green gasoline, green diesel and green jet fuel are found in a report sponsored by NSF, the Department of Energy and the American Chemical Society entitled "Breaking the Chemical and Engineering Barriers to Lignocellulosic Biofuels: Next Generation Hydrocarbon Biorefineries" released April 1 (http://www.ecs.umass.edu/biofuels/).

Sen. Byron Dorgan, a North Dakota Democrat will fill up a hydrogen-powered pickup "and hopefully drive off." Dorgan will be a featured dignitary at the dedication of a $2 million wind-to-hydrogen plant near Minot that he worked to fund over the past three years.

"This is really kind of a breakthrough project, using the wind to produce hydrogen," Dorgan said. "It's an exciting conclusion for me to see this project take shape."

Dorgan said the plant, which is about the size of a garage, uses intermittent power from wind turbines to produce and store hydrogen fuel without creating pollution.

The project is a collaboration of Bismarck-based Basin Electric Power Cooperative, the University of North Dakota's Energy and Environmental Research Center, North Dakota State University's North Central Research Center and other partners. Basin spokesman Daryl Hill said the project is a first for North Dakota.

Enphase Energy, a solar panel start-up which has recently acquired $6.5 million in funding, has introduced a new kind of solar panel system. In conventional solar arrays, inverters are separate entities from the solar panels, usually hung somewhere at a distance. This system by Emphase, however, integrates a "microinverter" onto the solar installation, allowing conversion of direct current to alternating current right on the panels themselves. Doing so will reportedly yield a more efficient system.

Renewable energy from the wind, which previously could only be generated in restricted geographic locations – typically off-shore or in remote rural areas – can now be made available almost anywhere, including urban environments, with the introduction of the AeroCam wind turbine. The AeroCam, developed by BroadStar Wind Systems, was designed and patented for commercial applications. With its parallel rotor blades, not only does it look radically different from conventional propeller designs, but also can be manufactured, transported, installed and maintained at lower cost.

“Wind energy now can be made directly available to everyone,” says Stephen Else, president of Dallas-based BroadStar Wind Systems. “By harnessing its power in almost any setting, the AeroCam can now generate energy close to where it’s actually required. This is a new and exciting product with great potential.” Following four years of research and development and the issuance of U.S. patents, the company is currently in the final stages of negotiations to place the product with two Fortune 100 companies.

Pretty soon, though, the biggest contribution we can make as individuals to reducing carbon footprint may not be a Prius in the driveway. Instead, it’ll be a Honda in the basement.

Last year Climate Energy in Medfield ran a demonstration project in sixteen Massachusetts homes, replacing their gas-fired forced-hot-air heating systems with a new high-efficiency “freewatt” system featuring a Honda MCHP (Micro-CHP) unit. CHP stands for “Combined Heat and Power.” The unit is a small generator that takes advantage of heat thrown off generating electricity to provide a second home heating source.

The results were impressive. Using the same amount of gas (or in some cases a bit less), the homeowners were able to both heat their homes and dramatically cut their electrical bills. When home electrical use was low, the owners had the pleasure of actually seeing the electrical meter run backwards.

The Tesla Roadster, despite being a 100% electric car, is considered by its makers as a sports car. And yes, the Roadster does have stunning looks that makes it look like a legitimate sports car. But even better is the fact that it is a legitimate sports car. 0-60 mph in just 3.9 and the top speed of a little more than 130 mph. The car is also capable of delivering an amazing 13,000 rpm. All that without burning any fuel.

The car truly gives the best of both worlds. It gives the thrill of speed (its acceleration rate beats the Porsche 911 GT3) without the environmental and monetary side effects of a gas guzzling super car engine. Other benefits include the fact that the Tesla Roadster can travel 220 miles before recharging. The elictrical cost to the owner would be roughly two cents per mile. That is like the equivalent of having a 135 MPG car that can still deliver the way performance oriented sports cars should deliver. It is one truly enticing car.

As a child, you might have used magnifying lenses to focus sun's rays onto anything you wanted to burn. Even if you haven't, you'd be well aware that it's possible to do so. IBM takes it to a whole new level and used a magnifying glass to significantly improve solar energy 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.

Whenone of the world’s mightiest corporations throws everything it’s got at a project, and when it shreds its rule book in the process, the results are likely to be impressive. Still, even for General Motors, the Volt is a reach. If it meets specifications, it will charge up overnight from any standard electrical socket. It will go 40 miles on a charge. Then a small gasoline engine will ignite. The engine’s sole job will be to drive a generator, whose sole job will be to maintain the battery’s charge—not to drive the wheels, which will never see anything but electricity. In generator mode, the car will drive hundreds of miles on a tank of gas, at about 50 miles per gallon. But about three-fourths of Americans commute less than 40 miles a day, so on most days most Volt drivers would use no gas at all.

Because it will have both an electric and a gasoline motor on board, the Volt will be a hybrid. But it will be like no hybrid on the road today. Existing hybrids are gasoline-powered cars, with an electric assist to improve the gas mileage. The Volt will be an electric-powered car, with a gasoline assist to increase the battery’s range.

The Savannah Research National Laboratory have created a multipurpose new material, composed of tiny glass bubbles, which behaves both like a fluid and a solid. Researchers at Savannah Research National Laboratory (SRNL) preface the news release for their impactful glass microsphere breakthrough, with a riddle. "What looks like a fertilized egg, flows like water, gets stuffed with catalysts and exotic nanostructures and may have the potential of making the current retail gasoline infrastructure compatible with hydrogen-based vehicles of the future – not to mention also contributing to arenas such as nuclear proliferation and global warming?"The spheres measure a scant 2-100 microns in diameter. This puts them at smaller than the width of a human hair. The key asset of the spheres are tiny pores which adorn their surface. These pores can be controlled by processing to measure from 100 to 3,000 Angstroms and they form full tunnels between the inner and outer wall, through which chemicals of controlled sizes can pass.A major application of the new material is gas streaming filtering. By adjusting the porosity, the material will act as a filter, absorbing one type of gas and letting the others pass.

Most promising yet, the microballoons can have their mechanical properties tweaked to act like a fluid, including flowing along pipes. This means that current gas distribution infrastructures could be modified to transport solid hydrogen, with little change. This in turn would amount in savings of money and effort spent. The hardy little microballoons are also easily recycled and reused, thanks to their strength. Toyota is sponsoring the SRNL to bring the technology to market to help it with its hydrogen vehicles.
