PS. According to my book, THE FREE ENERGY OF BINARY COMPOUNDS (available at Woodgas.com)
The Enthalpy of combustion of Al Al + 3/2 O2 ==> 1/2 Al2O3. Delta H (C) = 178 kcal/mole = 745 kJ/mole. The MW of Al is 27, so this is 27.6 kJ/g or 12,527 kJ/ lb. 1 kW hr is 3.8 MJ, so this is 3.3 kW hr/lb. Well worth capturing.
