   Philips used a small one (an air engine) for running a radio in Africa in   
   the 1950s. The prime reason they have never caught on is that large auto   
   makers do not  want to take the plunge. They had the ICE piston engines and   
   cheap oil and made money - to them, they did not want change.  The   
   self-serving corporateocracy advances like a snail.
