1.The cyclone engine has not been proven to be cleaner, and higher temperature burning can release more potent pollutants. Harry says its cleaner, but he says many things without giving verifiable numbers.
2. Fewer parts but many untested parts and systems, parts that have only been run for hours.
3. There is one part that I am particularly concerned about, It is somthing I believe he calls a spider gear, all the piston rods are connected to this gear ( Harry invented it), We do not know how this will hold up under real life conditions
4. We have cars on the road now that are running on natural gas. What fuel can a cyclone use that will give you more miles per dollar.
