New Batteries from IBM Could Store 10x More Energy

Posted on Wednesday, July 1, 2009 posted by posted by Mak @ 12:31 AM

IBM has announced that it is developing a next-generation rechargeable battery capable of storing 10 times more energy than today's top lithium-ion batteries.

The new batteries could be used to power cars and store power for smart energy grids, according to IBM.IBM's multiyear battery research project will also involve the use of nanotechnology, materials science and supercomputing.The company said it plans to discuss its work on the batteries at its Almaden Institute 2009 conference, which IBM said attracts "innovative thinkers" from academia, government research labs and industry.

The 2009 gathering will be held Aug. 26 and 27 at the IBM Almaden Research Center in San Jose. ( See more)

New Green Energy System to Capture Waste Energy

Posted on Wednesday, June 17, 2009 posted by posted by Mak @ 7:11 PM

A European supermarket chain, Sainsbury's is going to open its first "people-powered" store at its new store in Gloucester, using technology which captures energy from vehicles to power its checkouts.

Whenever a vehicle passes over the "kinetic road plates" positioned in the car park, energy is captured which would otherwise be wasted. Sainsbury's will channel the energy back into the store, saving power that would normally be taken from the National Grid.

The kinetic road plates are expected to produce 30kW of green energy an hour, which is more than enough to power the store's checkouts. The system, pioneered for Sainsbury's by Peter Hughes of Highway Energy Systems, does not affect the car or fuel efficiency, and drivers feel no disturbance as they drive over the plates.

New Powerful Laser System Could Create Fusion Energy from Waste?

Posted on Monday, June 15, 2009 posted by posted by Mak @ 11:46 PM

Scientists at the Lawrence Livermore Lab are putting the finishing touches on the world's most powerful laser system known as NIF (National Ignition Facility). In about 18 months, physicists will conduct a highly-publicized test to create fusion energy from water. It is part of a project designed to take the world beyond nuclear energy. But if it succeeds, the system could do more than create energy in a new way. It might actually rid the world of leftover nuclear waste in the process.

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.

ORegen : New Device for Capturing Waste Energy

Posted on Thursday, June 11, 2009 posted by posted by Mak @ 1:22 AM

At GE’s Global Research Center near Munich, Germany, scientists have developed a new waste heat recovery technology called ORegen — which is a device that converts waste heat from exhaust streams generated by equipment such as small gas turbines and industrial processes into usable electricity.This technology can help customers address the challenges of rising fuel costs and the increased demand for more efficient, environmentally friendly power systems and industrial plants.

They have modified Organic Rankine Cycles (ORC) - an old technology which can use lower heat input temperatures.Therefore, heat recovery now offers a great opportunity to conserve fuel by productively using waste energy to reduce overall plant energy consumption and simultaneously decrease CO2 emissions. For example, when an ORegen (Organic Regenerator) unit is joined to GE Oil & Gas’ PGT25 gas turbine, it can provide up to an additional 25 percent more power on top of the output of the turbine itself.

'Green Machine': Technology Generating Power from Waste Heat

Posted on posted by posted by Mak @ 12:22 AM

Green Earth, Inc. is an environmental company taking up the challenge of ‘greener industry' for the 21st century.A new technology offered by Green Earth Inc. is the "Green Machine" manufactured by ElectraTherm Inc., in Carson City, NV.

The "Green Machine" recovers energy value from heat that would have been lost, and uses it to produce additional electricity without emissions. The result is revenue from additional kilowatts generated, reduced emissions per kilowatt, and greater compliance with emissions standards. This technology has been tested and proven in Europe; and Green Earth recently completed an agreement with Electra Therm to introduce this breakthrough technology into the industrial markets of the Midwest.The Green Machine has the ability to create 50 to 500Kw of electricity from waste heat.The next generation of "Green Machine" products will be in the 5Kw range and extend these savings to smaller users in additional industry segments.

OIT Students Look At Ways to Clean Waste Vegetable Oil into Fuel

Posted on Tuesday, June 9, 2009 posted by posted by Mak @ 3:28 AM

Aaron Findley, a student at Oregon Institute of Technology in Southeast Portland, has devised a way to filter and clean used vegetable oil for use in cars and trucks that run on diesel.The project, called the automated biodiesel reactor was one of many student presentations featured at OIT’s 2009 Student Project Symposium. A wide array of renewable energy, information technology and mechanical engineering projects were included.

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.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
