Everybody building HHO generators should experiment with skelatal catalyst and optimize for max diffusion of the gas into the "casimir cavities" hydrino molecules forming inside these 2nm cavities can not twist back to normal orientation when they leave the plates and nature puts the extra energy in the covalent bond. when the molecule is combusted it has much more energy than the 2 original atoms..
