The Martin Aircraft Company has created the first jetpack that will be commercially available, the Daily Mail reports.
The jetpack has a height of five feet, width of five-and-a-half feet and a length of five feet, and features a dual-propeller construction that uses fans to provide lift instead of jets of exhaust gas.
Oh wow. This is going to generate some really great headlines. And that will be before we have to ban rednecks from riding them around in wildlife preserves.
I wonder how much it weighs. I wonder because it would be interesting to see, if it's light enough, how someone who flies it for a while would learn to use their legs for stabilization and maneuvering.
Well a jet is, from an engineering standpoint, a machine that takes a low-pressure incoming fluid (in this case, air), compresses it, and spits it out the other end at high pressure to create thrust. If all you're doing is burning fuel, you're just making a rocket.
EDIT: Yes, yes, a rocket is technically a jet, too. But my point is that this is likely some kind of turbofan, rather than strictly a helicopter/turboprop.
On the one hand, it's bulky, and it can't go for a long period of time. On the other hand, think of the potential for remote personal rescue situations where helicopters and such can't reach easily (provided that there's actual lift, rather than simply hover capacity).
