You can get self healing solar power if you grow bamboo and use the resulting charcoal for fuel. Carbon neutral I guess.

I bet using bamboo for power generation might be more clean that coal, especially if we turn the bamboo into coke first.

Granted I doubt you could "farm" bamboo like trees or other plant. Given how fast section species of bamboo can grow, which is a big benefit in this hypothetical, you would probably need a ton of water and no matter how nutrient rich the soil is you'd probably deplete the soil after a few harvests.

Shame considering how fast growing and dense bamboo is.

The resulting ash would contain the vast majority of the extracted minerals. Throw in some kitchen scraps to replenish nitrogen and you'd probably be self sustaining at a reasonable hobbyist scale.
