The welcoming community waiting on the tarmac when they landed gave them a flag. Bertrand and André have given a Clean Generation flag to each community in which they landed that was a scheduled stopover. This banner from the Washington DC

This is the highest efficiency reported for a black silicon solar cell technology. 18.7% efficiency means a power-to-size ratio of 187 watts per square meter of these cells. 7,000 watts (7 kW) of these

I think you’ll thoroughly enjoy it — I did! What do Archimedes, Einstein and Arnold Schwarzenegger all have in common? Answer: They’ve all contributed to the development of solar power.   From the 3rd Century BC when Archimedes fought off Roman ships by concentrating

In the solar powered world of the future you can spray-paint energy producing photovoltaic cells onto just about any surface, including windows. That’s what a company called New Energy Technologies
