Harnessing full capacity of Green Energy to generate electricity On Demand and a safe nitrogen-hydrogen fuel for today's gasoline vehicles

Resumen de: US20260187735A1

0000 By capturing un-utilized electric generating capacity at electric generating plants and other sources, then immediately using it to split water into oxygen and hydrogen to create stored energy, and using neutral nitrogen (N2) extracted from the atmosphere to reduce the explosive powers of hydrogen below that of gasoline, the carbon-free nitrogen-hydrogen fuel (NHV) created can be used in today's gasoline vehicles with modified tanks and carburetors and/or to generate additional electricity “on demand” without creating any CO2 air pollution. 0000 Although hydrogen has a lower level of flammability (a lower percentage of concentration in the atmosphere before it ignites) it also has a greater explosive power. Unlike today's EVs that take considerable time to recharge at recharging stations along our highways, an (NHV) would take about the same amount of time that it takes to refuel today's gasoline vehicles.
