[Stoves] Charcoal Stoves

[Tom Miles]

Dean,

Energy to Cook: 

You reported 23,983 kJ charcoal. http://bioenergylists.org/en/node/551

Does this mean that it took almost 1 kg (28,900 kJ/kg) for the test? Or did
you take into account the loss of energy in making the charcoal that you
mention below? 

Otherwise: 23,983kJ/0.67 = 35,796 kJ wood

The Rocket charcoal stove met all the wood burning benchmarks except Energy
to Cook. 2/3rds of the energy in wood is lost when making it into charcoal.
And in the two charcoal stoves it took a lot more energy from the burning
charcoal to boil and then simmer water. Burning wood remains a much more
energy efficient method for cooking. Reducing CO by creating a hot zone of
flame above the charcoal is a simple way to make it a bit safer, when used.

Best,

Dean
