We can also compare the 1 200 000 kJ to heat the house during 7j has its equivalent in wood or oil:

Our system saves:
1 200 000kJ / (3.9kWh / kg * 3600kJ / kW) = 85.7kg of wood
1 200 000kJ / (26GJ / t * 1 000 000kJ / GJ * 0.001kg / t) = 46.2kg of coal
1 200 000kJ / (42GJ / t * 1 000 000kJ / GJ * 0.001kg / t * 0.85kg / l) = 33.6l of FOD fuel oil

And that's all 7j in winter !! (also throughout the year but to a lesser extent)

Not too bad for a little palm oil 8)

Has anyone at least experienced the trick, because we're swimming in random speculation there?

It is a misnomer to say palm oil is true, it should be called "pure lauric acid" or assimilate it to coconut oil and palm kernel oil.

It is apparently good to specify that the data used are constants due to the materials used, nothing hazardous in them.
Nevertheless, I agree that it is necessary to test on a small scale before proceeding to the application.

I am still looking for European sites that sell lauric acid at a price below 10e / kg.
If in a week I can not find, I will buy from Chinese sites at 3e / kg.
