Just an idea that came to me..
Wonder what happen if a copper tube spiral ( work like a radiator ) was made outside on that hot spot for collecting that heat energy to a HHO cell in a circulating system, for lower amp and higher gas output, and then let the HHO gas produced be added to the Geet intake..
(Too hot with 400 degr, celcius for a hho cell, but you can just make the tube longer after the spiral so it water get cooler or let it cross that cool spot..80-50 degr. will give high output hho at great effency.)
1. Maybe heat collecting will mess up the function of the geet..i dont know..
2. Maybe dangerous if you get backfireing.. so be careful if you try this.
