Geothermal Energy: Harnessing the Heat Beneath Your Feet

Right below your feet is a source of renewable energy that is largely untapped. It heats groundwater by conduction and convection as it travels toward the surface of the earth. Lawrence Livermore National Lab scientists Carol Bruton and John Ziagos explain how geothermal energy can be used to generate electricity or heat buildings.

geothermal FTW

praise gaia !

Seems to me that Nikola Tesla (Most Genius Electrician Ever!) Had our energy problem figured out? Sure, the government act's like they want answers to the energy crisis but I'm not sure they aren't hiding them. If you haven't heard of Nikola Tesla, check him out. Until compassion for each other prevails over greed we may just chase our tails until the the earth shakes us like a bunch of flees. Let Civilization be more than just an idea!!!! Thumbs down to our so called democracy

@Snakez19 The heat from the earth is coming from radioactive material that continues to give off a heat at a nearly constant rate for millions of years. So yes we are cooling but it's too small to make a difference.

I think there are sustainability problems with geothermal though. By drilling into those rock formations we are letting cold water leaking to hot areas and decreasing the heat at that level. I think Enhanced Geothermal Systems is the unsustainable type that needs more work.

i have a question, if we do adapt this technology widely -- and we keep getting energy from the earth, wouldn't that lead to a cooling in the earths core or mantle? because ware going to be using its heat right, i am thinking more in the terms of , you have a hot bread and you stick a straw into it and suck the heat out, do you see where i am coming from in this question?

@shinviroz Thank you.

I'm wondering, what if we all got elektricity and heat, are there still wars, to what will it drive us then? you can only be monetary rich compared to poor(er). Even this disquillibrium creates flows, albeith that some are better in protecting then others.. When are we just happy, and strive for higher philosophies?

[rolandvanderent]

It is always been the same, take the fruit that is easiest to pick (why oilcompanies got so big, instead of biodiesel on which the first diesel engine ran or ethanol where the first T ford of Henry Ford ran on) .. Is it the right choiche? Cooling is releasing the hot temp into now and here.

But actually just for the engineering I would do it.. and offset oil

[rolandvanderent]

So, The question is: how will you be balancing?

There are already examples by "our" (lets call it human nature) conduct that icecaps are melting and waterlevels rising (bigger issue for somebody living in the Netherlands, the lowcountries). There are also stories or legend told: atlantis, or found: chinese sea contains ancient rectangular structures/ plates (piramide type?) as well as certain egyption structures..

[rolandvanderent]

Remind you we are already late for an ice age (for which most people living now would just appreciate, like me). it's still the balancing system the world lives by. By stopping the use of resources that are put safely deep under the ground (like oil, the old organic matter) with enormous forces/powers and bringing it into our habitat and which are actually entoxicating.
