Dragonfly helicopter runs on hydrogen

We took a look at an electric-powered helicopter earlier this morning, and here’s one that runs on water – yes, can you believe it? The Dragonfly relies on hydrogen peroxide that has been diluted to around 50% to 70%, where it will then power the 8″ long motors that generate around 102hp of power, allowing the Dragonfly to create enough lift for itself and a passenger. As for emissions, only water vapor is released, making this an instant hit with environmentalists. The Dragonfly is capable of keeping itself in the air for up to 90 minutes, and controlling it is simpler than you think. Too bad the engines are still relatively pretty inefficient, guzzling up to 11 gallons of fuel per hour. It will take four months for your $120,000 ride to arrive at your doorsteps.
