Time is distance as much as time is not distance. If there was no such thing as distance there would be no such thing as time as you would travel everywhere instantly. Hence time is always greater than distance. If time was less than distance time would start going backwards as you would...

Is a battery powered generator with permanent magnets likely to place less load on the battery than a battery powered generator with electromagnets all other things constant?

Wasn't sure if you could generate electricity by just spinning magnets within a coil or vice versa as well.:smile:

Is it possible to create electricity by spinning a coil between two magents?

If electromagnets in an electric motor were replaced with permanent magnets, would it make a significant difference in the amount of energy required from the motors power source?

Has it been proven to exist, and if it has, has anyone succeeded in conerting it into another energy such as electricity?

If the generator was not physically connected to the motor or transmission of the car, would it be possible to recover energy at a gain not loss? I'm not trying to create perpetual energy, just theorising about running an EV further before the batteries drain completely. The reason I ask is...

Thanks very much for that. I did wonder about how much weight the batteries and electric motor would add compared to a motor vehicle. It sounds very much like this theory would be far better off tested on a car. I was also thinking about trying to make a car alternator act as some sort of KERS...

The bike (electric bike) is what I want to power from the batteries. I would be mounting a bottle generator to run off one wheel. Hoping to return some electricity to the battery instead of none at all. Or would the friction created by the bottle generator rubbing against the wheel be greater...

I find that strange as for if the device did work I can't see how it would be perpertual energy as the batteries would still need to be recharged at some point. Say if you connected a large generator to a small one I would of thought momentum from the larger generator, not just the power it...

I am trying to work out a way mathematically if it's worthwhile to place a dynamo or generator on an electric bicycle to convert the bikes movement to electricity. Some dynamos create very little drag. By doing this I hope to prolong the time before charging the batteries again. What I think I...

Thanks! What I am also trying to determine is all the kinetic energy that is generated by the cars movement simply a result of the acceleration (velocity) itself. I'm guessing not otherwise mass would not be part of the formula for working out the amount of kinetic energy produced?

For example if a car accelerates from 0 to 10 kph it creates 50,000 joules of kinetic energy? If a car acclerates from 0 to 20 kph it creates 200,000 joules of energy. Does this mean that four times the amount of energy is required from the cars engine to go from 0 to 20 kph instead of 0 to 10...
