Cleaning the air by driving your car

Hey, I'm into soil carbon. I don't get emotional about much, but this kind of stuff make me wax rapturous.
This is such a beautiful solution to global warming I hope to God they can make it practical (and profitable) on a humongous scale. The people at Carbon Scientific have figured out how to suck carbon out of the air while producing hydrogen to drive your car with. The more you drive, the cleaner the air gets.

The process takes any kind of biomass (peanut shells, kudzu, leaves, twigs, weeds, whatever you got) and turns it into 2 extremely useful products:
1. Hydrogen - that you can use to generate electricity. The only pollution produced by turning hydrogen into electricity is water. Can you imagine every car in LA running on hydrogen? That big brown cloud over it would be a rain cloud instead.
2. Carbon granules made out of the carbon that the plants pulled out of the air and is never going back again. Mix these granules in the ground and you can turn infertile soil fertile - permanently. You can grow crops in the desert.

The process is exothermic - meaning once you get it started, it runs itself as long as you keep pouring leaves and twigs in. Unlike other ways of producing hydrogen, this process does not consume petroleum.

What's so great about that? Plenty.

• Energy would be a renewable resource, and could be produced wherever anything grows - the jungles of the Amazon Basin, Central Africa, Nebraska, Canada - anywhere. Farmers all over the world would be competing in the energy market - not just oil cartels.
  
• Hydrogen could be produced locally, right on the farm - and pipelined to neighborhood fuel stations for sale. Not shipped around the world in tankers. Terrorists could not disable an entire city with one bomb to a power plant because energy production is distributed all over the place.
• Instead of piping hydrogen, farmers could use fuel cells to produce electricity and sell it into the grid - reducing the need for giant smoky power plants. Everywhere electricity gets produced, greenhouse gases get pulled out of the air, not pumped into it.
• Carbon granules, when mixed in the soil, make a permanent fertilizer that holds nutrients at the root level until plants use it - nothing gets leached out, nothing gets wasted. Meaning that farmers could cut their use of P,N,K fertilizer to about 1/10 of what they use now. Terra Preta soil created by inhabitants of the Amazon basin over 500 years ago by mixing charcoal in the soil is still amazingly fertile after half a millennium. They sell the stuff by the bag. Here is a BBC special that was done on it. They think that the legend of El Dorado came about from DeSoto observing enormous civilizations based on the tremendous wealth that the soil produced. He assumed it must have been because they had piles of gold somewhere.

What comes next? They get this thing down to the size of a combine and cheap enough that a large farm could buy one. Biotech companies could produce crops with phenomenally high hydrogen content to kick up energy productivity. Since hydrogen comes from lots of sources (solar, wind, geothermal, biomass and petroleum) prices would be more stable than oil. OPEC countries would not be left out of the hydrogen market - they could break down petroleum, pipeline the hydrogen and keep the carbon. Farmers would not be dependent on food prices alone. You could expect people to start growing fuel crops where land is barren now. The air would gradually start getting cleaner. Soil would start getting blacker. Streams would run cleaner.

It's nice to know that while the bad guys are bilking us and fouling the environment, other people are quietly figuring out ways to fix things. I hope that an elegant solution like this ends up making somebody filthy rich.
