Oct 18 2013: Hi Allan,

you truly have a very rich and highly imaginative creativity, and you do not shy to think 'out of the box', which makes for the wide variety of your ideas.

Yet I like to suggest to you to take one idea at a time and have a first check on its overall energy balance.

Try to do this with the two following rules in your mind:

1) Action equals reaction
2) Energy can neither be created nor destroyed, it can only be transformed

Try to develop a feeling how the energy flows in a system, what it does and how it changes.

Let me do this with your first idea with 'bicycle generators attached to all tires' of a car' to find out how it behaves.

If the car isn't moving, so are the tires and the generators attached do not generate energy. So far so good. Now the car moves, the tires too and the generators attached produce energy. But now comes the important question, what makes the car move? In order to move the car, it burns fuel, which is a liquid form of stored energy. Therefore the original cause what makes the generators produce electricity is fuel. So the highest efficiency for the generators to produce electricity was, if the care engine was directly attached to them, because anything else in between would only create losses.

So you transformed chemically stored energy (fuel) into electrical energy (generators) but where is the benefit to do this with a car engine? For this we already use - more or less - optimized power plants to produce electricity and this way much more effective than a car engine could. So where is your intended benefit?

Additionally, the battery in the car adds weight, the generators add weight and create a lot of friction (moment of resistance), the copper wiring adds weight and all of this reduces the miles per gallon dramatically. So overall you are loosing more energy in your setup as if the same amount of fuel was burned in a specialized power-plant to produce electrical energy.

Do you understand what I mean?
