Gasification solution for 10 kW & 20 kW

I came a cross an interesting post from CNET

Not 100% sure why they would call it carbon negative since, as far as I know, the source, in general is still above ground type carbon matter

The only clue is the generated highly dense charcoal if indeed its aim is to bury them or to use as fertilizer and hence be a carbon trap to inhibit the introduction of more CO2 into the atmosphere.

I can definitely see this as a possibility for smaller scale residential heating and electrical power generation, and to a certain degree looping back again to the whole idea of DG (Distributive generation) rather than large scale wasteful power generation and long over the line distribution.
