Halfbakery: Hydrogen Peroxide Car Motor

H2O2 or Hydrogen Peroxide is an unstable molecule being esientially a water molecule with a extra oxygen atom hanging on Disturb it and the water molecule will happily fling off that pesky oxygen with considerable energy The result is about half the energy density of hydrocarbon burning but the result is just water and oxygen H2O2 rockets work by injecting the liquid into a catalyst pack
