Solar Energy Can Be Accumulated In Concrete

Monday, December 8, 2008 13:38 No Comments

Concrete could be used for thermal energy storage, according to researchers from Arkansas University. They have won a prize worth 770,000 dollars from the U.S. Department of Energy, within a programme for supporting the projects of cheap solar energy accumulation.
Solar panels are used to pull the heat that to be stored than in concrete. [...]

“Black Silicon” Could Change Solar Energy Generation

Monday, October 13, 2008 0:10 No Comments

Recently was discovered a new material named “black silicon” which could be used to change the solar energy technology because in comparison with conventional silicon is between 100 and 500 times more sensitive to light.
Look how this material was discovered: a team of scientist from Harvard University, before adding sulphur hexafluoride, they shone an ultra-powerful [...]
