I was wondering exactly how the heat of the Earth is transferred to the water…

My science class is doing a Future City Project, and i have this pressing issue about explaining how the geothermal energy extraction works with underwater volcanos.(my city is underwater). I know HOW it works, but cant put it into words. Help is much appreciated!

Can you provide explanations or links on systems that have been tried (perhaps even successfully) to harness heat during summer for use in winter in a large scale – essentially a very large battery?
I am somewhat aware of utilizing geothermal systems where the relatively constant underground temperature is used to heat cold water pumped down in winter, and cool warm water in summer.
I also know that energy is stored for shorter periods of time (typically overnight) by pumping water up to a reservoir during low power demand times to be used during peak loads.
What are other areas of research, and how much success has there been?

I have an old furnace which I can’t afford to replace.I also have three wells on my property.One is drilled 120 feet deep and two shallow wells abou 4 feet deep.Can I use any of these for geothermal heat in the Connecticut winters?

We’re doing uses of volcanoes in our class. Our teacher wants us to do something extra about geothermal energy. And we have to give it in by tomorrow. so help

I’m doing a project in which i must make a model of a geothermal heat pump, and since they obtain heat from water….i was just wondering………………………….…
ps it has to be save things, nothing like antifreeze or nuclear energy, and something i can easily obtain would be nice too

If so, do geothermal heat pumps harvest and store this heat for last use, thus preventing any of it from going outside?

This link provides info on the geothermal heat exhchanger system. http://en.wikipedia.org/wiki/Geothermal_…
Its very much the basic exchanger system.
Can anyone explain to me how heat is extraced from the house during the cooling process??

Geothermal heating/cooling systems are no longer experimental, as the article below, excerpted from the Albuquerque Journal, clearly shows. Most people seem unaware that geothermal sources of energy can be used in many areas, not just where hot springs are located! Were you aware that geothermal options like this existed?

Community College using deep tubes to heat, cool site
By Rosalie Rayburn
Journal Staff Writer
Central New Mexico Community College is counting on the earth to heat and cool its first Rio Rancho campus building.
A Texas-based drilling company recently began boring a series of holes into the dirt on the construction site where CNM will house classrooms for nursing, computer, information technology and liberal arts courses.
The 300-feet-deep holes will carry a network of polyethylene tubes that will circulate water into the building. Engineers who designed the system determined that the earth’s temperature at that depth is a steady 68 degrees. Water circulating from the holes will help raise the building’s temperature on frigid winter days and lower it during the heat of summer.
CNM officials picked the geothermal temperature control system over conventional heating and cooling technology because it offers a cost effective way to avoid using fossil fuels, said Luis Campos, CNM’s director of physical plant.
Geothermal heating and cooling technology has been around for at least 30 years, but it’s gained popularity in recent years. The city halls in Rio Rancho and Las Cruces and the new V. Sue Cleveland High School all use geothermal systems, said Jeff Greenup of Loop Tech Inc.
Greenup is overseeing the Loop Tech crew that’s drilling the wells for the CNM building. Loop Tech has done drilling for geothermal systems throughout the Midwest and at several sites in New Mexico, including Las Cruces city hall and the new high school in Rio Rancho.”
