Crushing rock is very energy intensive, transporting rock to farms is energy intensive. Placing rock in the soil is energy intensive. Its hard to see how this passes the B/S test.

Yep. It's easy to skip the TCO analysis to make it seem like it's "helping" in the context of a study trying to sell another study.

The Bill Gates-associated method of spraying fine lye in a hyperboloid tower seems the most effective, perhaps at a slightly higher pressure of 2-3 atm to both increase the temperature and reactivity. The lye would be produced in a closed carbon cycle process using renewable energy sources.
