1. They pour cold water into the center of the earth to produce steam to turn turbines, which makes static electricity which can be converted to either AXC or DC to power homes.

2. Yes evidently that dude is very very wrong. Geothermal energyis where they pump cold water into the earth and then it comes back up as steam to drive the turbines like normal plants do, they just get the heat differently. Yes, as i said, that dude has one hell of a bad brain. oh and by the way, i dont think the redlands are exactly suitible for geothrmal energy, unless they set up one in Rotorua then channeled the energy to the Redlands.

3. Geothermal energy, energy contained in intense heat that continually flows outward from deep within Earth. This heat originates primarily in the core. Some heat is generated in the crust, the planet’s outer layer, by the decay of radioactive elements that are in all rocks. The crust, which is about 5 to 75 km (about 3 to 47 mi) thick, insulates the surface from the hot interior, which at the core may reach temperatures from 4000 degree to 7000 degree Celsius (7200 degree to 12,600 degree Fahrenheit). Where the heat is concentrated near the surface, it can be used as a source of energy.

4. Basically let me run you through the Organic Rankin Cycle. You find an area that has hot ground water. You drill a well then flow test it. If you have enough gpm (flow) and heat, 300+ degree F is ideal, you need to find somewhere to re-inject the water because you can’t just pump it out on the ground after it goes through the plant. You need to put it back into the ground. So you drill another hole and flow water into it from your production well. By doing this you are testing your heat source. Your looking for a good flow of hot water and re-injection that won’t cool off your heat source.

   OK lets say you have all that, next you build you plant. And as I said before I’m going to take you through the Organic Rankin Cycle. Organic saying you are using an organic liquid, a hydrocarbon called pentane C5H12. Normal Pentane has a boiling point of 97 degrees at sea Level. Your hot water from your production well goes through a heat exchanger instantly flashing your liquid pentane into a gas and increasing the pressure to a great amount. That gas pentane is forced over a turbine which turns a generator producing electricity. Now after the pentane passes through the turbine it is cooled by air fans or water, and condensed back to a liquid. That’s the Cycle of the pentane. flashed, turbine, condensed, then flashed again etc…
   Now your Geo water once it goes through the heat exchanger it’s still hot, so you can do some things with it before you re-inject it. You can extract minerals from it. There is a plant that gets zinc from its injection water. Most plants that use the remaining heat use it to dry things out like corn for ethanol, onions, and other various things. After you have used all possible heat form your water you re-inject it into your heat source to heat it up again and reuse the water for flashing the pentane again. To research you project more find a map of hotwells in your area and their temperatures, also distance to the grid from the hotwells. They also use parabolic mirros to heat oil up from the sun and run the Oganic Rankin Cycle using the oil to flash pentane.

5. type on google “enrgy sources” and pick the first one then go geothermal (it has a quiz) and good info

6. Geothermal enegy comes from below the earths surface. when theyre formed they are hot springs and geysers. The water travels through under ground into really hot rocks and is then turned into steam.

7. work harder and go to

   it will tell you every thing you need to know!
   give me 5 stars and best answer! pretty please
