Yes.
Mr. Fission is the king of miniaturization.
You can probably make incredibly small fission reactors that would work and produce energy. So long as you have a way to get rid of the waste products that is.
Mr. Fusion is the king of make it big. I doubt you could ever make a stable energy yielding fusion reaction that would fit in a car.
Let's not mention the flux capacitor and the probability of time travel.
