Rolf, This is kinda old news. They have been testing for some time with Hydrogen. 
the RX-8 style engine is perfect since they
can set the ports for no overlap event. There is squawk that the side 
ported "8" engine started life in their H2 testing. There
are papers which are a couple of years old. Use H2 powered 
cars in google. You will probably get hits for the Mazda paper. Bill
