A method and device for generating hydrogen and oxygen from water using the heterodyning or impacting of two radio frequencies on the surface of water in a shielded and grounded enclosure, with separation and collection of gases accomplished by a superimposed manifold. One radio frequency is higher than the other, one typically in the ultra high radio frequency bandwidth (UHF) and the other typically in the very high radio frequency bandwidth (VHF). The heterodyning creates two additional radio frequencies that are also used to fracture the water's molecular bonds. The method is clean, odorless, silent, and environmentally friendly, with no residue, fumes, or other unwanted byproducts. Optionally, water filtering means, water heating means, saltwater, and/or fresh water can be used. A water spray can also be used to increase the water surface area available for bond fracture by the radio frequency disturbance.
