The Electric Car's Song
I heard this is a little old, but it fits into GreenOptimistic's subjects, and, there sure are people who haven't seen it.
30% Efficiency with Gallium-Nitride Silicon Solar Cells
The Phoenix-based company RoseStreet Labs Energy has developed a prototype solar cell that combines gallium-nitride with silicon, a technology that achieves an efficiency of 25 to 30 percent.
New Electronic Circuit Cooling System Offers Brighter Electric Car Perspectives
Researchers from Purdue University discovered precisely how fluid boils in capilary cooling sytems, and that by designing a system by using those rules they got a much more efficient heat transfer between the object to be cooled and the liquid.
Clean Hydrogen Obtained Through Thermolysis of Water by H2 Power Systems
H2 Power Systems, based in the UK, has designed an on-site and on-demand hydrogen producing system based not on electrolysis, but on thermolysis, which is the splitting of water at very high temperatures.
Tesla Motors Introducing Swappable Battery Pack for Model S
As battery mileage efficiency for electric vehicle is still in huge debate and controversy Tesla Motors came with a great idea to please its buyers.
Biodiesel Developed Safely from Rhodococcus Bacteria
Using synthetic biology, researchers from Massachusetts Institute of Technology (MIT) are trying to develop a new bacteria similar to the tuberculosis root to produce biofuel.
New Nanostructure Film Reduces Solar Cells Reflection for Better Efficiency
Oregon State University engineers have innovated a new nanostructure film technology that they can deposit on any surface and reduce the reflectance of light. Their technology should perform better and have a lower price.
Fraunhofer Develops New, Easy to Make High Efficiency Solar Cells
Yet another efficiency record has been established for mass-producible solar cells: 23.4%. The Fraunhofer Institute for Solar Energy Systems (ISE) from Germany succeeded to manufacture a single-crystal silicon solar cell of a thin p-type semiconductor layer residing on an n-type semiconductor substrate. The solar cell's area is 2x2cm.
Steorn's Free Energy Machine to Be Tested One More Time This Year
Maybe you've heard about Steorn and their Orbo. Steorn is an Irish company that has been promising for a few years to accomplish something mankind has been dreaming for thousands of years: some call it perpetuum mobile, others call it overunity, but it is mostly known as "free energy" in lay terms.
Spain Transforms Phone Booths into EV Charging Stations
One of the major cities in Europe, Madrid, has found an innovative solution to give a new meaning and usage to the phone booths.
