don't know what you mean by "restore some energy" but Stirling engines are good at generating some electricity from all the heat that an engine produces. (although in that case they are called Stirling generators. nit picky I know) Thermoelectric generators (also called Seebeck generators) are another good one to look into depending on your needs.

I have an affection for the Minto wheel, but that is largely laughed at by the few who know what it is. I think the reason for such dismal performance is do to poor optimization. If correctly modified I am confident it could be competitive in certain applications, although it still is unlikely to be the power house it was originally claimed to be. The real gain is very cheap and simple construction combined with the ability to harvest very low levels of energy that otherwise would not be used with simple direct mechanical output at high torque & low RPM.
