[Gasification] Charcoal Gasifier No 2.

[Energies Naturals]

Grid feed is not a universal anwer.
Only where it is heavily subsidized you can operate a plant  successfully.
Remember it takes 1 kg of goog biomass to produce 1 kwh of  electricity (in 
large facilities!)
The thermal "waste" is way more valuable.
Only grid feed is linear thinking, what we need is more diversity, imho.
