I want to build an EHD and attatch it to my bicycle

http://en.wikipedia.org/wiki/EHD_thruster

Ok seems simple enough. Its an electronic engine, it creates an ion wind to generate thrust.

A single stage EHD thruster generates 2 newtons of thrust for an input power of 200 watts at 50 kV

But how much electrical energy would it take to propel a human on a bicycle?

Would it even be possible to generate the amount required?

2 newtons, at 200 watts???

Even if you could get it scaled up...the power requirements would bury you.

Strap the Hoover Dam on your back, and you have it made. Actually, rough estimate would be around 70,000 watts to accelerate an average person at 1m/s on flat ground. 70,000 watts is around 90 some odd horsepower. Assuming I did the math correctly (in my head) and didn't mess up on the physics (much). Very rough estimate.

Why don't you go the whole hog and use a photonic laser thruster instead? :tongue:

What about a car battery and a tesla coil?

Soz my science is crap!

Naaa, that utilises an engine.

I wouldn't need a license for an electronic propulsion system.
