  1. Geothermal Power Justin Henriksen & Dom Quade

  2. Source • Earth's Crust- Difference in temperature from surface to about 10 meters down • Can be anywhere, but most favorable sites need accessible hot springs • Western U.S. is a hotspot

  3. Technology • Tap into naturally occurring "hydrothermal convection" where cooler water seeps into Earth's crusts, is heated up, and then rises to the surface • http://www.youtube.com/watch?v=-ajqiPe_9Ko • Special heat-absorbing liquids • Complex series of coils and pipes in residential sites

  4. dry steam power plant

  5. Flash Steam

  6. Binary Cycle Power Plant

  7. Uses at home • Heating and Cooling • Constant Ground Temperature at 10m. • Can be anywhere

  8. Electrical Production • Needs to be at a hot spring or other place of tectonic activity.

  9. Industrial Costs and Obstacles • Greatest cost is building facility for electricity plant. • New technologies for smaller-scale operations could be a tipping point. • Coils and pipes could be the next big thing.

  10. Residential Costs and Obstacles • Digging costs high, but pays for itself very quickly. • Heat-absorbing chemicals, pipes and coils are becoming easier to implement.

  11. Environment (large scale) • Needs land to set up power plant and other apparatus, but not as much as a caol plant. • No mining • Carbon-free

  12. Environment (small scale) • No real environmental costs (all underground) • Chemicals well contained • Good for environment, lowers CO2 emissions

  13. Investments • Better at small scale • Big plants risky • Nevada plant under performing • Can save 70% on heating and cooling in residential and businesses
