I manage to get all the stuff today. need time to build one now...... washer hydrogen cell. something like this .., YouTube - (Video 32) NEW Washer DryCell Hydrogen Generator Design (HHO, Brown's Gas, Hydroxy) not sure how much gas i am getting ......... i cant find cheap 304 or 316L washer... it was RM15 each for a small 304 washer and i need like 21pcs of it so its 21x RM15 = RM3XX ? so i just bought some cheapo metal washer to try out first. only cost rm0.80 each . LOL! cant seem to find the gasket as recommended so i just went to my regular bike shop and get a free used tyres and cut them according to size. hope it works and seal between the plate. seem like this topic is dead. probably becoz fuel is cheap at rm1.85 ? i doing this project not coz of fuel price, but becoz of how drastically it improve my car performance interm of acceleration and pick up and engine really quiet. i cant even imagine my car is running without this. probably its an old 26yrs old car. anyway, hope those who still into this HHO project can share some info or your project. maybe can work some better design or something.... ? HHO for life.
