3. GTherm Green Boiler SWEGS HeatNestTM
Thermal Energy
SWEGS
17.5” (0.45m) diameter well drilled to region of hot rock
Lateral holes drilled out into hot rock
Heat pipes grouted into lateral holes to harvest heat and bring it to central well
Heat exchanger transfers heat into closed loop
Closed loop brings heat to surface
Heat pumped to heat/production reservoir wells
87.7°C
HeatNestTM
The current EGS approach works but creates the following problems:
Gaseous emissions
Water pollution
Induced seismicity
Induced landslides
Requires a significant amount of water
Requires two wells – drilling wells is the most expensive part of the project
Negative environmental impact

8. Why GTherm? GTherm SWEGS is a Closed-Loop System
The water coming from the HeatNest to the pump is continuously recycled (i.e. no waste water)
No groundwater contamination
Closed Loop System
Constant and Continuous Heating
GTherm SWEGS is designed to pull heat from earth at 20% less than the refresh rate
The heat resource is constantly replenished and never consumed
Environmentally Safe
No fossil fuels
No greenhouse gas or other emissions
No chemicals required for extraction 8

9. Why it Works SWEGS is modeled after heat pumps
There are millions of heat pumps installed and operating worldwide

20. GTherm Green Power
Annual power and cooling operating costs < $2 million per MW
Prices escalate 1% per year
Independent of fluctuations in cost of fossil fuel
PPA funds all development for redundant power and cooling – PPA can optionally fund facility
Based on customer requirements, GTherm believes the modular approach will significantly lower data center construction capital 20
