Why doesn't /sci/ believe in hoverboards? >Can't

>bush, swamp and crevasses
If you live in those areas you're probably broke as fuck, with exceptions for some drug warlords

People are too fat.

Because 15 minutes by the time I'm 32 is fucking useless, good hover boards will be about when I'm too old to give a fuck

What kind of hoverboard are we talking about? The magic kind in OP's picture, or the kind which uses a cushion of air underneath of an inflatable skirt?

>>7976413
At 30 mph that is nearly 8 miles. Also not everyone is an old man like yourself

This is a major problem. My design is for an 85 kg person, 90 kg max, 110 kg person? Forget about it.

I'm afraid reaction propulsion is the only real propulsion system in existence.
>he kind which uses a cushion of air underneath of an inflatable skirt?
You are thinking about hovercraft. Even that will struggle in the roughest terrain. It's also bumpy.

Tough terrain exists all over the West. Canada, USA, Australia etc. I heard ice is a real bitch in Canada, imagine if you could just fly over it.

Tell me OP, what is the physics behind a hover board? Please explain in detail. Once you explain that, please tell me how I will be able to mass produce said boards. Once you explain that, please tell me why it is better than a skateboard or bicycle as a mean of street level transportation.

Spin propeller with electricity
Spinning propeller pushes air downwards
Air pushes you upwards because Newton
Antigravity!
>Once you explain that, please tell me how I will be able to mass produce said boards
Pay a factory to make propellers?

Moves as the crow flies, impervious to traffic, more fun.

Funny, the contrarians are nowhere to be found today...
