The amount of modeling and calculation involved in trying to determine the efficiency of a conceptual engine is nearly insurmountable. Before you go any farther you should realize that there are people out there that have already tried to invent what you're looking at (and I'm sure they've filed patents as well).can somebody tell me how to calculate efficiency?
I know for a fact that's isn't true, because I've seen a design nearly exactly like yours in past years. Perhaps you haven't looked hard enough (or at all)...yes i've checked there are no toroidal engines which resemble my design. could anybody tell me what to do next?
