Emission-Free Jet

by Terrence O'Brien on April 19, 2007 at 04:41 PM

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.
