Dr. Tom, Can one hammer mill->ball mill the Al into a powder and burn it directly (stand back!)?

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.

Keelynet, which describes a method of converting Aluminum into its oxide and in the process cracks water, freeing up hydrogen for use as fuel for a light car. By all accounts, using this gas in the place of any other fuel. Distances and the amount of metal used in this attainment were mentioned. I was hoping for a reaction from one of the many “Energy Economists” Who lurk on this site, to respond with negative information regarding the impracticality and waste fullness of such a process? I believe there is a large following on this site who are interested in obtaining electrical power using renewable energy, derived from carbon neutral sources. They might question the economics and ethics of using a refined ore as fuel. Instead of chopping down oxygen producing vegetation. In this respect I am a nonconformist. I believe most Aluminum is produced by Hydro electric power and, so the CO2 is not in the equation. My second comment is harnessing a “free” supply of high temperature heat which is emitted from most Ice’s in the form of “Hot Exhaust”. This is the place to install a reactor capable of converting beer cans into hydrogen as not too much energy would be needed to complete the reaction. Bubbling super heated steam through a molten bath of AL would give pure hydrogen. No tar, and the ash is a hot commodity The real question is: how much energy is locked up in a pound of AL gfwhell _______________________________________________ Gasification mailing list to Send a Message to the list, use the email address [email protected] to UNSUBSCRIBE or Change your List Settings use the web page http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org for more Gasifiers, News and Information see our web site: http://gasifiers.bioenergylists.org/
