Errr, no, not really. The thing about reversible computing is that it takes 
just as much energy to run in the forward direction if you want to progress 
at the same speed. If you get half way through a calculation and stop 
applying a power gradient, you're equally likely to go either direction. You 
can use arbitrarily little energy, but you'll go arbitrarily slowly forward.

Quantum computing is the only *actual* reversible machines out there, afaik. 
  (Well, reversible in the sense of actually saving power to do so.)
