How would you like an engine producing your dear electricity? How would you like that engine to have pistons as high as heat-powered balloons? Well, an environmental consultant from Solartran in Brisbane, Australia, by his name Ian Edmonds, has designed such an energy producing "engine" from the classic and romantic air balloon.

Current hydrogen fuel cells work at temperatures for up to 100°C for PEM types, and up to 300°C for SAFC (solid acid).

You go somewhere for the holidays. You have your mp3 player to forget about the "dead times" during not-so-interesting-travels. But what? Suddenly your mp3 player stops working! Noooo!
Robert McGinnis, Yale doctoral student and Menachem Elimelech, Chair of Chemical and Environmental Engineering, have developed systems that can harness the power of osmosis to transform non-potable water sources like seawater to freshwater and generate in the same time electricity.
The EV1 has been a dream that ended up quickly and painfully for everyone to forget it. Although it's an oldie, this movie shows the facts that stood behind the decision of not only shutting down the EV1 production line, but also destroying all of them altogether.
