The CVT (continuously variable transmission) technology is already being used in hybrid cars, and now it enters the wind turbine industry. Texas-based Viryd Technologies, use CVTs to make the fluctuating wind speeds convert into a more efficient stream of AC current that will be fed to the grids.
Georgia Tech researchers have developed a system that uses dye-sensitized (Grätzel) solar cells wrapped around optical fibers to increase their overall efficiency, since it's known Grätzel cells are not very efficient. The fiber solar cells they obtained are 6 times more efficient than zinc-oxide solar cells having the same area.
The construction of this universal solar charger is very simple and cheap(only $50) . You don't need to have any familiarity with electronics or prior circuit knowledge. It can be used to charge any device via USB.
SOLARIG, a Spanish solar company, has started construction of 8 photovoltaic parks in Itlay this month. When the construction will be ready, the parks will provide 8 MW of clean energy in total. The same company plans to build photovoltaic projects that will produce 30 MW throughout different regions of Italy.
A guy named Mylow has tried to, and seemingly succeeded to build a magnetic motor whose power was self-sufficient to run it. The invention was not his, but Howard Johnson's, who, in the 80's, tried the same experiment and at that time it's said it was a success. Anyway, nobody seems to have publicly replicated the magnetic motor until Mylow.
According to a recent report by SNL Financial, a business research firm, more than half of all planned energy projects in the Northeast Power Coordinating Council region, comprising part of Canada and 6 US states, are renewable energy projects.
Today's plug-in hybrid electric vehicles (PHEVs) require an overnight charge back at your home, but scientists at Commonwealth Scientific and Industrial Research Organization (CSIRO) have found a way to use these PHEVs as large mobile batteries that can be integrated...
Former General Motors economist Walter McManus reveals some shocking statements that show GM not only ignored the consumers' wishes regarding fuel efficiency, but intentionally misled the public opinion on fuel efficiency.
They went 501km with one battery charge, from Alice Springs, in the Australian Northern Territory, to the finish marker at a point 183 km north of Coober Pedy, in South Australia.
A Swiss company based in Staefa, claims it developed zinc-air batteries, capable to hold three times the energy of lithium ion batteries, by volume, while costing only half as much," and compared with other existing air batteries, this one would be rechargeable.
