grk more expensive than nuclear, page-31

Ohmygod,
the concept of the underground heat exchanger is fairly static between projects. All operations (except PTR) will be stimulating the natural jointings and fractures in the granite. Then a large reservoir must be established to ensure adequate surface area for heat exchange, and increase flow rates.

These factors are common. As such, the pricings behind these factors have common elements. The power plant costs will be similar. The conversion of heat to electricity will be similar (except for the Kalina Cycle). Operating costs will be similar.

Just because the figures we have to work with are not exact, does not mean they cannot construct a representative idea of costs.
