The Biochar Economy
Concept: Broadly, this refers to various products and processes dealing with biochar, either in its production, transport or end use. Biochar is a carbon-negative product, i.e. its production takes carbon out of the atmosphere and puts it into a form that is stable in soil for a long time. This is an exothermic process: while it does not yield as much energy as full gasification or combustion, it still gives off some useful energy. The idea behind the "Biochar Economy" is to try to embed biochar production into as many processes as possible. This concept faces the challenge that it is considered "less efficient" under the current economic paradigm when only the energy yield per unit of biomass is concerned. A change in mind set towards a carbon negative economy (example: 350.org) is therefore required for this to become widely accepted and implemented. The products listed below would be too expensive under the current paradigm but would actually be more economical if the costs of future climate disruption are internalized.

Future Dedicated Wiki
The number of applications for such a new ecomomy is vast. Therefore, a dedicated wiki is needed.
