Insane idea?

Question

I'll answer that myself. Yes. The question is HOW crazy. Generate energy by-

Have people wear magnetic inserts in their shoes (voluntarily)

Plant induction coils under the sidewalks

Walking becomes a little harder=Good exercise

Coils produce electricity!

The energy comes from people, many of whom are overweight anyway, fat is one of the few energy reserves we have a surplus of!

Everybody benefits

Answer 1

mmm pretty unique idea but it might be expensive but coal is cheap.

Welcome to the world of half-baked ideas.

My idea was of a piezo rubber insole called Nike-power. you just plug your Ipod into it and it generates power each time you weightbear on it. - Nothing happened to it though.

Lots of inventions on moving traffic - from wind vanes to load cells and moving roads to recover the energy mechanically from passing lorries.

My personal favourite has to be an induction loop to charge a capacitor - using all the shops door security systems each time you walk through - you pick up a charge. when high enough, it will discharge a pulse to charge your battery. You can also pick up free charge from unshielded cables or lighting - anywhere with a magnetic field.
