Could you build a PSG with an RMH whose exhaust piped underground into a manifold or looping series of pipe like in the Ceres Greenhouse Systems? What would happen if you could use all that extra heat and pump it into the soil?
Could you get a cheap, tropical greenhouse even in the northern reaches?
I do some of my very best work in water. Like this tiny ad:
Experience months or even years of natural building and growing your own food
