Kor37 9 Posted April 19, 2007 The Hyfish, a hydrogen fuel-cell powered unmanned aerial vehicle (UAV), made its maiden flight over Switzerland recently. The small jet hit a top speed of 200 kph (roughly 124 mph) and even managed some acrobatic maneuvers. Right now the craft is merely a prototype, but we're sure to see a military application in the near future, especially with the engineers claiming that 15-30 hour flights are within reach. With Earth Day quickly approaching, it's also worth noting that hydrogen fuel-cells are a zero emission technology -- meaning they release no pollution or green house gases. If this technology is successfully scaled to commercial airliners it would have an immensely positive effect: Aviation is attributed with being responsible for 4-9% of the human impact on global climate change. Funny how no mention of this technology is mentioned for cars. I know they are working on it. I'm also sure that the oil industry is doing all they can to suppress it.... :P Share this post Link to post Share on other sites
