Yes, there is no engine installed on the Dragonfly DF1, but rather tiny hydrogen peroxide rockets at the tip of each blade. Reportedly, "it can stay aloft for 50 minutes and has a maximum speed of 40 mph." Video after the break.
The hydrogen peroxide rockets (the same things that power most jetpacks) produce no pollution and are supposed to be significantly more stable than their conventional counterparts due to the lack of, um, an engine.[via OhGizmo]
