Imagine one of these running, say, a pressure vessel to provide torque for a scooter, maybe with a pop-off valve, so it can provide the power to the wheel. Runs of natural gas or alcohol or diesel fuel or propane. Whatever. Turbines will even run off flour or sawdust, did you know? Most jet engine powered vehicles had direct drive to the wheel and really strong brakes to slow them down, which is really stupid. You can't use a clutch in traffic because they have too much torque. However, if you did this running a pump for something like a hydraulic drive, you could avoid the whole electric motor problem (rare earths, wheel weight) and focus on just using the available power supply and the CVT to get this to work. Would be really interesting compared to a normal 49cc 2-stroke. Probably more expensive and less reliable, and a 2-stroke doesn't actually EXPLODE when it fails, not like a jet engine does. So maybe that's a terrible idea. It is INTERESTING, however.

Jet Turbines For Fun And Profit
So did you know you can build a homemade jet engine out of spare parts and coffee cans?
It's not a great engine. Makes more heat than thrust, and tends to melt bearings so it seizes up. And keep in mind that the speeds these things go, if the engine fails, it explodes really spectacularly.
This one is really nice, almost professional level. Most are more about the melting.
They're very much about proper balance.
This one here is the best construction, with properly made CNC turbine blades and balanced. Nice. And proper bearings so it won't melt and seize.
