Does the article describe how the heat gets from the mound to the houses or buildings it plans to heat, or factor in the cost of that?
Naively, I'd assume that would like 90% of the cost.
I know that physics is under no obligation to be intuitive, but it's also surprising to me that it's so easy to heat and keep dirt this temperature (600C / 1100F) throughout Winter, and I didn't see how that piece worked either, though I'm willing to assume that part is figured out and factored in.
