Because of the volumn of HHO that you burn, you would need to compress the gas. Much more expensive and a lot more dangerous. Using a propane tank would be a bomb. That is the problem with hydrogen as a stand alone fuel. In order to get any decent range, the gas must be stored under hundreds of pounds of pressure and can you imagine what would happen in an accident.
I have not built one of these kits yet, but generating the gas as a suppliment, only on demand does seem to have some merit.
