German Jetpack Runs for Hours on Water
- RiderOfGiraffes 18y agoHow can it have a range of 300km/185 miles when it's effectively tethered to its water supply? How can you call the water "fuel" when it's simply being used as a reaction mass, and the energy supply is at the pump? I could go on, but it seems singularly pointless. Cute toy, great fairground ride, useless as a "jetpack".
