I think the concept is to use fumes not mean fuel droplets like a carburetor .i watched one of the other videos & under full acceleration fuel was flying through the inlet tube into the engine it had no metering unlike jets in a carb.. The concept is more along the lpg theory running on a gas . I think it might be ok at idle but once the engine is inducting at high rpm it will be worse than a carb or injection .GBN said:Pure Genius, he made a very primative carburettor out of a jam jar.
He's only about 150 years too late with this one.
