$100M xPrize for Carbon Removal

I'm sure it's been mentioned elsewhere here already by someone, but I've always thought that converting felled 'sequestration stock' to bio-char and making terra preta out of it would be win-win-win, as it could then be used to improve desertified land.

As much as CO2 emissions befear me, so too does increasingly poor topsoil, globally.

I'm not even sure we'd need to wait for trees to mature either - we just need work with whatever plant absorbs the most CO2. Perhaps algae, even?

This is definitely a thing: https://en.wikipedia.org/wiki/Bioenergy_with_carbon_capture_...

In theory it's energy positive: burning the crop can produce energy.

So I’m thinking the same. Soil + Terra preta(charcoal + food waste) is the best way. There needs to be some kind of inverse Bitcoin - something where we incentivize large number of people to claim areas of land and terra Preta it up. The reward is some kind of token that can be exchanged for value. We can maybe use satellite imagery to identify which land has been converted. Someone has to be forming a team on this for the prize.
