Like turbines, rotary engines were an interesting idea that just didn't bear fruit in consumer automobiles. Not only are they less fuel efficient than traditional four stroke designs, but they produce more pollution and tend to burn oil prodigiously. No offense to Dave Delman, but electrically propelled automobiles aren't the future either. Battery capacity just isn't there, and I don't think it ever will be. The curious thing about batteries is: No matter how big the cells are, each one only produces about 1.5 volts. >From AAA remote control batteries to humongous railroad locomotive batteries, this 1.5 volt cell limit seems to be constant. Of course, no matter what propels our automobiles, propulsion alone can't solve the problems of gridlock, sprawl, or an aging driving population. The solution to America's transportation ills is of course right in front of our faces. We merely need to use various options already in existence more rationally. Europeans have been doing that for decades. For some reason Americans tend take this argument to extremes: Either trains OR buses OR self driven automobiles. The solution is trains AND buses AND self driven automobiles. With the odd DeLorean thrown in the mix, of course. >--- In dmcnews@xxxxxxxxxxxxxxx, Farrar Hudkins <fhudkins@...> wrote: > > Well, the Wankel rotary engine was discarded in light of the fuel > crunch.
