Well that would be great Jubal. I'm going to find out, because that would be the logical way to do it. Reclaim the water and use it in agriculture.

This is a great story and I am sure that the water is reclaimable when it is used to break up the solids.

Geothermal energy history
Geothermal energy is literally, “earth heat”. This type of energy's name comes from two Greek words: “geo” meaning earth, and “therme”, which means heat. While it may seem that the use of geothermal energy is a relatively new idea, it is actually an ancient practice. Many different cultures have used geothermal power to their advantage, and geothermal energy history dates back to some of the Earth's earliest civilizations.
In order to use geothermal energy, the energy source itself must be tapped into. Geothermal energy comes from reserves of water located in the Earth's layer of magma. Magma, otherwise known as molten rock, is a super hot substance that springs directly from the Earth's core, which is a scalding 9,000 degrees Fahrenheit. Magma heats the reserves of water located in its midst to very high temperatures, around 700 degrees Fahrenheit. These geothermal reservoirs, as they are known, can be drilled into or can escape naturally through cracks in the Earth's crust. These natural formations create such places on Earth as hot springs and geysers.
Geothermal energy history can be traced back to 10,000 years ago when Native Americans used geothermal water found in hot springs to cook and for use as medicine. The geothermal energy found in hot springs was also used by the Romans. The ancient city of Pompeii used geothermal energy to heat homes. Romans also were known to use geothermal water for its medicinal properties; such as in the treatment of skin and eye diseases. Romans and other ancient civilizations also used the soothing geothermal waters found in hot springs for relaxation and natural bathing places. In more recent geothermal energy history, France started using this type of energy in the 1960's to heat their homes. More than 200,000 homes in France are now heated by geothermal water

There is great knowledge in ancient wisdom and we can indeed gain a lot of insight from the past to a better future.
Also relates to ancient architectural/archeological sites, which were built understanding the natural flow of earthly energies to make the best of all environmental situations. (we've touched on how we build our buildings makes a huge difference in energy consumption...) - 4 years ago

In October 2007, the Government released the New Zealand Energy Strategy to 2050 (NZES).
As part of the Strategy, the government has set a target that 90 percent of our electricity be generated from renewable sources by 2025.

Well, I cant find this post anywhere now and have seen other good posts pushed to the back of this site while the garbage rises to the top. The staff here then needs to do something about it. It isn't fair to people who come here to post news and information and actually have a dialogue with others.
And what is the tag ?Source. ?

Every time I try to recommend this response, I get bumped to the top and it's not recommended!?
I'm with you on this one Jan, the site it so full of celebrity T&A crap that I'm wondering if there will be room for anything else soon?
Some of the stuff I've been reporting as spam "complies with our community standards and will not be removed."
Since the website is getting an overhaul, maybe we need to overhaul the community standards.
I know not all my posts are great, but when someone has a concern about what I've posted and they let me know, I try to at least respond. These spammers on Current, won't even give me a reply, they're too busy posting the next "nipple slip" or "up skirt" or "free movie download" to even acknowledge my comments.
WTF Current? Help! Please? Pretty please?

Yes, it seems this site is being invaded by trolls. And please, posting T&A is not news and should be against the community standards. I don't want to see that garbage everytime I'm searching for real news. I thought this site was supposed to be different than the tabloid MSM garbage on tv. Maybe we were wrong?

I've been having the same problem. I no longer can recommend responses to other people's submissions, but I can recommend responses to responses. The edit tag to my responses doesn't usually appear any more, either, so I can't make corrections to my responses. I can no longer recommend other people's submissions, only my own (my ego is not inflated enough for me to do that), and I can recommend (some of the time) responses to my own submissions. Also, the voting tabs only work once in twenty or so times, but there is no problem voting for submissions on the front page. I've written to current about this problem several times - by email, through responses and by messaging some of the staff, but I have had no reaction whatsoever so far. I think that in the process of revamping the site, a major glitch has occurred in the programming. Other people, however, seem to have no problem recommending responses and submissions not their own. If more of us write to Current about this, perhaps something might get done.

JanforGore, the evil spammer is at it again - he posts long lists of links to sites which install trojans and other malware - whatever you do, do NOT click on any of these links. Perhaps it because of all the garbage that good posts get lost in the mess...

The Great Rift Valley extends from Lebanon in the north to Mozambique in the south
Formation of the rift valley is what gave ape,dog,cat and grazing mammalians an edge 30 million years ago, now the cleanest & cheapest form of endless energy known to man?
Is this why The Great Rift Valley is the "BIGGEST WAR ZONE/KILLING FIELD/market for MILITARY-INDUSTRIAL-COMPLEX" in eternity?
DRAWING LINES BETWEEN CONFLICTS DOSE NOT SHRINK THE PROBLEM (see ww1 & ww2)

How EGS Works.
The only problem I personally have with this is the amount of water used in the fragmenting of the rock. I need to do more research to find out how much is needed in a particular instance. Anyone with any information on that please feel free to post it here. Thanks.

I found this. It's a lot of water. But, if I heard right, the enhanced system recycles water.

FTA:
How much water does a plant require?
Answer: The flow required depends on the temperature of the fluid, the ambient (sink) characteristics, and the pumping power required to supply and dispose of the fluid. Excluding fluid pumping, a closed-loop binary-cycle geothermal power plant would need 450 to 600 gallons per minute (gpm) to generate 1 MW from a 300° F fluid with an air temperature of 60° F. If the fluid temperature were only 210° F, one would need 1,300 to 1,500 gpm to generate the same amount of power. If an evaporative cooling system were used, 45 to 75 gpm of make-up (clean) cooling water would also be required to generate 1 MW. - 4 years ago

Great news, this would also reduce the energy required to mine and transport coal, build and manufacture pipelines for oil, and so on.

From the article:
Areas across the world, from Guatemala to Papua New Guinea, are beginning to plug into geothermal energy as a new and promising alternative to coal and oil-fired power generation.
The century-old energy technology that taps steam from hot underground rocks is also poised for a massive expansion up East Africa's Rift Valley in the 21st century.
The United Nations Environment Programme (UNEP) and the Global Environment Facility (GEF) have completed a project testing advanced seismic and drilling techniques in Kenya that has exceeded all expectations.
Wells of steam, able to generate 4-5 MW of electricity and one yielding a bumper amount of 8MW - enough to power about 5,700 homes - have been hit using the new technology.
This could mean a saving of as much as $75 million for the developer of a 70MW installation as well as reduced electricity costs for generators and consumers, experts estimate.
The results, announced at the UN climate convention conference in Poznan, Poland have now paved the way for an international effort in 2009 to expand geothermal up and down the Rift which runs from Mozambique in the South to Djibouti in the North.
The project, funded by the GEF and involving UNEP and the Kenyan power company KenGen, could also transform the prospects and costs for geothermal elsewhere in the world.
Achim Steiner, UN Under-Secretary General and UNEP Executive Director, said: "Combating climate change while simultaneously getting energy to the two billion people without access to it are among the central challenges of this generation. Geothermal is 100 per cent indigenous, environmentally-friendly and a technology that has been under-utilized for too long".
"There are least 4,000MW of electricity ready for harvesting along the Rift. It is time to take this technology off the back burner in order to power livelihoods, fuel development and reduce dependence on polluting and unpredictable fossil fuels. From the place where human-kind took its first faltering steps is emerging one of the answers to its continued survival on this planet," he added.
