[QUOTE="steveflatman, post: 2220107, member: 745624"] The main issue with most of the ideas here is not lack of willing on the part of consumers, but the manufacturers assesment that most of them would be impractical due to the wiring requiremetns and voltage instability of electricity produced by an 'irregular' event. However things are starting to change, there are cars available which have electric 'booster' motors to aid ecceleration, which when not in use actually re-charge their own batteries, thus utilising some of the wasted kinetic energy expended when going down hill or coasting. There are hundreds of ways to create clean energy, the best idea I've seen yet was a friends idea for an armband mounted MP3 player. It would contain a thermoelectric cell, which would convert body heat to electricity when exercising, this giving you completely free music when working it out, not sure if he ever got it off the ground though. One thing to be mindful of is that utilising a process that was going to happen anyway will provide what can be termed as 'free' energy. However performing a function in order to generate additional power will always utilise more energy than it actually generates as all forms of electrical generation suffer from heat loss. Driving a hybrid car to the top of a hill would use more energy than it would generate on the downwards slope of the hill. Even winding a handle to charge a phone would actually use up more chemical energy than it generated in electrical energy, as there would have to be losses due to heat and sound. [/QUOTE]
