can a vehicle be made which will run forever without any fuel?

Question

I mean to say that it will have a self recharging mechanism inside it.like rechargeable batteries.It will run on electricity.Wind or solar energy can be used to recharge inside mechanism,instead of recharging it with electricity.

Answer 1

yea, i was gonna say wind and solar energy are fuels too. Solar energy is possible but I dont see how wind power can because...wind slows down your car when you collect its energy and then you are using that same energy to drive the car. However, energy transfer is never 100% so wind is not really an option. solar panelled cars maybe.

Answer 2

Well, it seems impossible now, but we can try to make it. But I want to remind you about efficiency. No machine made till date ever has efficiency 1. They all cannot give as much output as much of inputs we give. A littlew bit of energy is transformed in another form not required. Hence, even if some self recharging mechanism is developed, it will stop working after considerable amounts of time because, the machine will produce less energy than it requires.

Answer 3

Even the best solar cars so far have to have an enormous roof for all the solar panels, and that was using special lightweight materials. I think Popular Science did an article on a race across Australia between the best solar cars. You might be able to get a back copy of that. Good Luck!

Answer 4

Without an input there can not be a output. One form of energy gets converted to the other. This is basic law of physics, You know it.
If a vehicle has to run without fuel, it will need some other form of energy as an input.
Technically speaking, it is very much possible.

Answer 5

i think starjoy got wide imagination and i like his answer ,well done chap!!!!
others are cliches like wind power, solar power and the like...
congrats for you also for some out of the way thinking
there were vehicles without fuel in the past but now they are obsolete
haven't you seen FLINTSTONES.
not joking but such an engine will suit your request
now biomechanists are working on engines that work on
muscle power , that is ,somehow tap lactic acid and other
respiration byproducts into power

what about an engine that will produce its on electricity
from it's wheel rotation ,like a dynamo,[idea from cycles]
let us provide a little kick to the engine initially with some sort
of power and then it continues moving with its own power.
may be it an produce power for domestic purposes when the
vehicle is not in use

Answer 6

If a vehicle could convert its mass to energy, it would damn near run "forever" without the addition of any outside sources of fuel of any type. Unfortunately, that technology isn't available today.

Perhaps, in the future, we will get the elusive "cold fusion" and utilize it in a sports car.

Never say never.

Einstein would be proud of this vehicle.

Answer 7

Yeah it is possible. We can use selenium plates to convert solar energy to electrical energy.If we make the body of the car with selenium we can charge the batteries in the car which can be used to run the car and it will be surely environmental friendly without any pollution

Answer 8

Fuel is fuel - wind, solar, gas, whatever. And nothing is free. (First Law of Thermodynamics) And to BPSKI, a perpetual motion machine comes in three types, depending on which of the three main Laws of Thermodynamics you try to break, not Newton's Laws. And the Theory of Relativity is Einstein's.

Answer 9

a solar fuel celled car can make use of the heat energy obtained from the sun which is converted /stored in the cell as electical energy to drive the engine continuously during summer seasons.
in winter seasons it will be difficult to make use of the same form of energy ,during such time we will have to think of storing the energy converted from solar fuel cells in the form of a battery , from which during the entire summer the excess of electricity which has been generated by the solar fuel cells will be charged in terms of a lead carbon/lead acetate batteries which will be plentiful in numbers
and provide for continuous life during the winter.

Answer 10

I seriously doubt there will be a car like you describe - to overcome the friction of the road, wind resistance, and carry the weight of passengers involves a lot of energy. Even hydrogen fuel-cell technology cannot accomplish that.
