Photovoltaic organic solar cells have the potential to be truly green, but often their manufacturing processes are not so green.
Petroleum- and silicon-based solar cells can be bad for the environment and nearly impossible to recycle. One possible solution to...
![Basic Construction of the Phinergy Aluminum-Air [AlO2] Battery Cell, Just Add Water](https://i0.wp.com/www.greenoptimistic.com/wp-content/uploads/2013/03/Battry2v4.jpg?resize=350%2C213&ssl=1 "Phinergy’s Recycled Aluminum-Air Battery Could Power Future EVs")
Aluminum-Air batteries are nothing new, but a recent innovation by Phinergy, as well as compelling test data, could solve electric vehicle range concerns.
We all know the arguments against electric vehicles, “Unless you spend $100,000, you can't get any decent...
Urban pollution caused by nitrogen oxides can now be predicted for specific locations at particular hours, thanks to recent study done by scientists at the University of Castilla-La Mancha (UCLM).
The researchers developed a geostatistical method that takes into account...
A new refrigerant developed by Honeywell and Dupont, HFO-1234yf, will be required by law to replace R-134a, but Volkswagen is rejecting this and developing its own carbon dioxide air conditioning system.
The new refrigerant, HFO-1234yf, is supposed to reduce greenhouse...
Green walls have been acknowledged as one of the most effective ways to cut down city air pollution, improve building's energy efficiency, reduce noise and at the same time give a warm green feel to the usually colorless city...
In recent times when electric vehicles like the Nissan Leaf and the Tesla Model S have become so popular, no of these electric vehicles have focussed on offering anything like Formula One performance. But that is all set to...
The latest technology by the giant Panasonic, a "thermoelectric tube," is being tested at their Northeastern Clean Center in Kyoto City for its power generating capabilities.
The tube can produce electricity from hot water by creating temperature differences between the...
When power plants burn coal, wood or even refuse to generate electricity, the leftover ash generates hydrogen gas, which is why it must be stored outside.
Leftover ash from power production often finds its way to landfills or, in some...
According to a study conducted by the USDA Agricultural Research Service, the burning of biomass in the form of switchgrass, instead of oil, could cut down energy costs of companies and homes.
The study shows that this is particularly true...
With the development of nanotechnology, researchers using nanowires in solar cells are finding that solar cell efficiency limits may be higher than they previously thought possible.
Current commercial silicon-based solar cell efficiency is less than 15%, which means that more...
