Wake Forest’s Plastic Fiber Solar Cells Doubling Energy Output of Flat Ones
Posted by Ovidiu in Solar Power, Uncategorized on April 10, 2010
Solar cells get efficient as time goes, but there are methods to improve the performance of current ones, made with older technologies. Wake Forest Center for Nanotechnology has just received a patent for a new solar cell technology that can double the energy production of current silicon flat cells at highly reduced costs.

Dye-Sensitized Solar Cells Got Better by Using Ionic Salts
Posted by Ovidiu in Solar Power, Uncategorized on October 14, 2009
Grätzel cells work by using the interaction of a structured semiconductor less than nanometer in size and an organic dye acting as a solar collector. Many tweaks to the Grätzel cells are done at the dye level, but this one is different.

Your Home`s Excess Heat Could Get Recovered by New Cheap Machine
Posted by Ovidiu in Uncategorized on November 24, 2008
This article doesn’t talk about huge producers of energy, or doesn’t mention the use of any prime matter to create energy, but instead it focuses on recycled one. Ener-G-Rotors, a company based in Schenectady, NY, is developing a heat recycler that can work with lower quantities of heat, under 150°C, unlike those of the competitors, aimed only to the higher-class, industrial energy producing stations.
