The propeller has the added benefit of letting the car be used in the water à la the Amphicar of old. Include a tidal generator in the car and when you run low on juice, drive to the nearest shore and into the ocean and let the tide generate electricity to recharge the battery!We should put a wind turbine on the front of the car and a propeller on the back of the car and we can go forever.
If the automated rock dumper used less energy than you gain from going down hill then yes, it would kind of work until you run out of rocks on top of the hill. When that happens new rocks (or the same ones) would have to be transported up to the top of the hill again. This requires energy.
This is why you should fill the car (bladders) with locally captured rainwater at the top of the hill, and dump the water at the bottom of the hill. This enables you to extract energy from the natural water cycle. Just use bladders that do not leak.
Do both the water wheel and the bladder.
Why lower the overall efficiency like that?
Thank you kindly.
How does that lower efficiency? The water would get to some point, probably, where it has no useable head but would still flow into the bladder.
That's a great idea for a youtube video!One "rural gentleman" who saw my Tesla suggested plugging a 110V inverter in to the 12V power socket, and then plugging my car in to that "to get extra range".
I thanked him for his insight...
I'd like to see him retry his experiment on his hybrid vehicle with an empty gas tank.You mean like this one?

Water at height has potential energy. Putting it in a bladder, thus increasing the mass of the car, at height and diving it down the mountain will give you a bit more energy into the battery, but you are putting more wear on the car from having to carry more weight and the method is very inefficient.
Instead if you let the water flow downhill through a turbine the potential energy would be turned into water head to turn the turbine and generate electricity. The turbine would have some wear from use, but the electricity generated per pound of water is much greater than the bladder idea and the wear on machinery per KW of electricity generated is much less because the turbines entire purpose is to sit in one place and generate electricity whereas the car is going to see more wear. For one thing you will be seeing wear on your tires as well as stress wear on the suspension from carrying the extra weight.
Any way you want to slice it, generating electricity from a stationary generating source and then charging up a car from it is far more efficient than any idea to charge a car through some sort of mobile device. Now regen braking is not completely efficient, but it's recapturing energy you have already expended and the alternative is to lose that energy to heat.
Diesel locomotives have used the same principle for braking since the 1950s, but in their case, they have just wasted the energy to heat with giant resistors and vents on the top of the locomotive.
Regen braking reduces your losses, but it isn't an answer for replacing charging from an external energy source.
