Researchers from Norway figured out how to make nano-particle clay they could dissolve in water and just dump on sand. It penetrates deeply, so then you can add fertilizer and seed. Their process takes 7 hours from sand to a planted wheat field! The fungal mat you need for most plant growth thrives in this stuff.
I am stoked. Add this to Loggy's biochar process, and we have a sustainability system. (Just add sun.)
There’s still the problem to be solved of how to cause the economic machine of Capitalism to get behind these particular kinds of solutions. Can we rely on the profit motive? Wall Street? Investment banks?
