Feasibility of wood vs. charcoal - volume considerations
- start with a nice graph of energy density of fuels - [1]
- Wood pellets - 640 kg/cu m [2]
- Volume density of wood chips- 240-520 480 kg/cu m [3]
- Volume density of charcoal - 240-480 kg/cu m [4] ; 208 [5]
- Energy volume density of wood - 14-18 MJ/kg
- Energy volume density of charcoal - 30 MJ/kg [6], [7]
- 1MJ = .3 kWhr -> 1 kG of charcoal has 9 kWhr of energy, tapped at 10% - gets us ~ 1 kWhr of energy. 1 kW hour of energy per .5 - 1 gallon of fuel
