And with this "great" movement towards hibryd technology, people are forgeting about the great amount of hazardous waste this can create not to mention the cost. Batterys have a life span and many toxic chemicals are with in them....Im sure there is a recycling solution in place but it is of concern where all these battery packs may end up.

Good points. However, rotary engines still have the equivalent of all four of these strokes. The area of the combustion chamber is still decreased during the compression and exhaust "strokes", and increased during the power and intake "strokes." The only difference is that these "strokes" are accomplished by the eccentric movement of the rotor, instead of the up and down movement of a piston. Either way, it still takes the same amount of energy to compress the air/fuel during the compression "stroke." There may well be efficiencies due to reduced friction, less mass changing direction within the engine, etc. I am not an expert on engine design, someone here probably knows.
I completely agree with your concerns about battery waste. Hopefully there will be an industry recycling these components when/if hybrids become widespread. I would hate to see all those heavy metals end up in landfills. Lots of people now have the same concern about old computers.
