If you are interested in climate change, you’ve probably heard of biochar. It’s basically charcoal, which is produced not through burning, but through heating biomass in the absence of oxygen. It has the amazing fertilizer qualities and when used in this way is actually carbon negative by sequestering carbon in the earth.

The video, produced by Raw Science, shows Dr. Frank Shu, a celebrated astrophysicist and Shaw Prize winner now dedicated to making an impact on climate change. He has developed a process that converts biomass to carbon neutral (or negative) coal that can be enhanced by a molten salt nuclear reaction. Check it out.
