Hi David,

The burn rate of HHO can be slowed by pulsing magnetic coils on the gas as it is produced.

Xogen mentions some of this in his patents and even Stan Meyer's showed the concept in his very first patent, which was in Canada.

I don't necessarily agree with the orthohydrogen vs parahydrogen concepts, but it seems documented enough that pulsed coils affect the burn rate of the water gases.

I have seen only video demos of the water gas burning slowly on a stove type burner situation.

It seems the concept can be carried to the ICE.
