its only ~50 homes

  > Optimal community size would be 200-300 homes to realize the economies of scale. The number of systems would remain the same; only the number of boreholes would need to increase Decentralized systems like this one are cheaper and faster to build so it makes sense that the number of households served is on the low end. That doesn't mean it's not useful tech.

    It’s interesting. 7 million in support to supply 97% of annual heat for 52 homes isn’t that far off being reasonable for an early R&D project. An 80% price drop at modest scale, say 100 different 300 home subdivisions actually seems achievable. I think it’s largely a question of how dependent this is on local geology.
