ive been screwing around with designs and ideas for a while now and built 2 hho generators, one with 6 plates and one with a tube and coil. at 12v 2amp the tube + coil was produceing alot more hho than my 6 plate design with practicaly zero heat after 5 minutes. both are "wet type" generators. also, the 6 plate one i made is twice the size.... im thinking SS tube + coils are the way to go for efficent hho production. i cant help but to feel like that hhofreak guy was right about plates being wrong, its just too much bulk with not enough production. if we are trying to build an electro magnetic field, a wire wrapped around a tube (or rod mabey?) just seems like the right direction.
