[Gasification] Tennessee company - pyrolysis biochar + hydrogen ($1.75 per gallon diesel-equivalent?)

Dr. Karve,
I think you have the "People's Answer"- distributed energy made from recycled organic materials.  Your work is very important to many people around the world.  I salute you and your work.
