One thing I've been wondering is whether is possible to power a ground effect vehicle from overhead wires. That would sort of be like a hover train. The "tracks" would be cheap to build. Just need to compact the ground to a smooth surface.
- mpoteat 7y agoSan Francisco has this. Buses are powered by overhead wires. (because electrified tracks would kill pedestrians)
- _tulpa 7y agoLots of places have that, definitely almost nobody has ground-effect vehicles (which would satisfy the 'hover' bit): https://en.wikipedia.org/wiki/Ground-effect_vehicle https://en.wikipedia.org/wiki/Ground-effect_vehicle
- fulafel 7y agoThe need to constantly produce lift would probably consume a lot of energy.
- dzhiurgis 7y agoI think solar energy is enough, at least for small prototypes.
- chungleong 7y agoLift-induced drag goes down with the square of velocity. At high speed, the need to stay aloft doesn't cost you that much.
