Amazing Helicopter With No Engine – The Dragonfly DF1

If after watching this video you do not want to own one of these helicopters, I question your sanity.  This is simply amazing.  A small personal helicopter, the Dragonfly DF1, can fly with no engine.  Instead of an engine it uses small hydrogen peroxide rockets (no pollution) on the tips of the blades.  The small H2O2 rockets can keep the helicopter in the air for approximately 50 minutes and can travel at speeds up to 40 mph.
