Wheel or axle alternators as supplementary energy source.
Properly mounted alternators on each wheel or axle with correct gear ratios to allow power generation while the car is in motion but only engaged at near HIGHWAY SPEEDS... that would provide enough energy to A. Slow battery drain on primary bank... B. Charge a secondary bank of batteries... and/or C. Run limited amount of secondary equipment while using no battery energy at all. Again only at near highway speeds. This is NOT meant to power the vehicle in any primary fashion. It is just meant to be used as a supplementary energy source, such as heat energy being used from braking is used. I sent this idea to Ford many many years ago and still have the draft sketch of the idea I made back then if that is required.

Dennis T I have commented on this type of idea. LOTS and LOTS of kinetic energy in turning wheels. Also, Serial Hybrid: use less gas by turning a generator.. A EVs (Electric Vehicles) range needs to be longer. I did a Bing search on 'electric motors' and Siemens came up. I was educated about the difference between 'Parallel Hybrid' and 'Serial Hybrid'. 'Parallel' uses the combustion engine exclusively to turn a transmission for power to the wheels: it only uses the electric drive motors to get the vehicle moving or sustain a low MPH. 'Serial Hybrid' uses electric motors "exclusively" to drive the vehicle and the combustion engine is used to drive a generator to power the electric motors and re-charge batteries. Diesel-Electric trains do this very well. The "combustion engine" could be a small power plant that uses fuel cell tech, or Natural Gas, or gasoline then engine size does not have to large. The electric motor has a lot of torque so it can handle any load or any application. Siemens has been around and produced electric motors since the late 1800s. Ford and Siemens could combine: Ford engines and vehicles with Siemens electric motors, controllers and other electronics to produce a planet loving vehicle product.

Matthew D @ Jonathan M. -Thanks I appreciate that. :) @Polly K. - Yeah this is mainly an idea for electrics only or hybrids. Alternator system on this would not use a belt drive alternator (has friction under belt pressure) but instead use a gear connected spin wheel/fly wheel connection on the alternator/s. Thanks for commenting, I value all feedback on this idea. :)

Jonathan M Great idea! As I see it, I believe it's very likely the engineers at Ford could make this work. (Assuming they don't have this on one of their concept electrics already of course.) It's a fairly straight forward idea and not that difficult to build a prototype model of to test the concept.

Matthew D ADDITIONAL NOTE: Alternators have near complete zero friction and this system would cause no mentionable extra drag on drive shaft or wheel while it is engaged.

Polly K If the car runs on gas, it will take more fuel to run this generator. Why not just charge the extra battery from the alternator? On an electric car it will shorten the range consuming power to charge the battery.

Matthew D This is not related to perpetual motion energy source, just so you know... read idea carefully. :p
