well can a rotory engine run on some hydrogen or something

I don't know all the facts but my Mazda Dealer told me that there is a kit for hydrogen that can be purchased in Japan for a mere $40 K. It can be used on 8s. The problem is low power, water vapor that forms in the system, and where to find the hydrogen... which costs more than gasoline to make, as of now!



I was interested in alcohol because we raise a lot of grapes here, but current 8s do not like gas-alcohol mixes.
