There are three (3) total products, which together form an end-use value-added hyhdrogen energy economy. First, HyOx Engines with many applications, efficacious engine systems that burn hydrogen and pure oxygen, producing more power/torque per displacment at near 2 - 3 times the fuel efficiency. Second, from natural gas and sunlight electricity and hydrogen are economically produced. Electricity is < $0.02/kWh and hydrogen is < $2/kg. All produce only water; No COX. No NOX. And, no SOX.
