Well, we could e-mail the idea to geologist or scientist in the field.
See what they think about it. I would think that we would do it in areas that have low population densities as well as being low on life and waste, perhaps North Dakota. The energy could then be transferred to another power station where it could be used to take water and make hydrogen via electrolysis.
It could then be shipped all across the country to various power plants for use, or used for hydrogen cracking in heavy crude hydrocarbon deposits(oil shale), in order to produce useful oil for our oil infrastructure. It wouldn't be a perfect solution but it's better than the alternative.
BTW, I'm all open to alternative power source ideas as long as there is some feasibility behind them. To me it doesn't matter if there dangerous to consider as long as there feasible, because the alternative to little energy is for the most part death.

Ixnay on the ailmay chief, I don't think too many of them pointy-headed geothermal / nuclear physicists would grok the sheer genius of what your proposing. We need to start thinking in terms of what two determined , smart go-getters such as ourselves can accomplish with a little planning and elbow grease . By the by , I recently read a story about how lax security has been at the nuclear storage facilities in some of the former soviet bloc countries.Just something to mull over while we think of those glorious underground explosions. _________________ It's the height of rudeness for the stretch polyester pants crowd to foist their tard version of Christ on talmudic scholars.

What if we dropped small nuclear bombs deep in the ground, exploded them, and used the heat to construct geothermal hot spots.
Its already hot deep under the ground. The earth's heat flow produces higher temperatures the deeper you go. Places like volcanoes are exceptionally hot. There is no need to set off nukes to make it hot.

What kind of idiotic post is this? Don't you morons have a life? It is nice outside and it is a weekend.
Shouldn't you dweebs be at the beach ogling girls you will never touch, or in the backyard torturing your neighbors' pets? _________________ ree rah rip ram. sunofabitch godamn. hidey didey christ almighty. rah rah crap

That's right Pstarr , you go out and have a good time sniffin' bikinis and what not , secure in the knowledge that me an' Kylon are hard at work makin' sure that there will be a liveable planet for you and yours well into the future. We don't want accolades or even acknowledgement of the hard work we're about to undertake on everyones behalf , just a little understanding would be nice. _________________ It's the height of rudeness for the stretch polyester pants crowd to foist their tard version of Christ on talmudic scholars.

I like the 'liveable planet' part. I've noticed an increase in complete absurdity here at PO. Before this place was smug and constructive. Now it appears the loonies are running the fun house.

Hey pstarr , why you being such a freakin' jitblob ? Why don't you take your own advice and go outside for awhile ?99% of the threads here are serious and the other 1% are probably thought to be serious by those that start em'. Who the Fark are you to tell us we can't joke around once in a while? You don't like it go read the geopolitics or global economics forum. Or better yet if you don't like the look of a thread title don't click it! We already all have mothers and we're not looking for another one . _________________ It's the height of rudeness for the stretch polyester pants crowd to foist their tard version of Christ on talmudic scholars.

I haven't done this before so I'm just going to quote the entire article, because I have found that sometimes if I try and find an article on the stuff website that's more than 3 months old, it no longer exists.
Quote:
Mighty River Power will spend $450 million building a geothermal power station at Rotokawa, 10 kilometres north of Taupo.
The state-owned electricity generator and retailer told Parliament's commerce select committee yesterday that the station would generate 132 megawatts of electricity, enough for a city the size of Tauranga.
Company chairwoman Carole Durbin said Nga Awa Purua would be the second biggest geothermal power station in New Zealand.
Mighty River was granted resource consent for the station in December, and procurement contracts are due to be completed this month. The station will be built near the existing, much smaller, 37MW plant and will connect to the 220-kilovolt transmission lines that run directly over the field.
Nga Awa Purua is a joint venture with the Tauhara North No2 Trust, and will take about 2˝ years to build.
Mighty River chief executive Doug Heffernan said Nga Awa Purua was first talked about 20 years ago. "It didn't happen at that time because the country had so much cheap Maui gas and it was too expensive to develop the field."
Mighty River will also commission its $300 million 90MW geothermal station at Kawerau this year.
Mr Heffernan said geothermal generation would make up nearly half of all generation by 2015, compared with about 5 per cent two years ago. Hydro generation would make up the other half, down from about 80 per cent two years ago.
Mr Heffernan told the committee that rain at the weekend had filled the hydro lakes enough to provide an extra month of storage, easing the pressure on winter power supply.
Yesterday Environment Minister Trevor Mallard appointed Judge Gordon Whiting to chair a board of inquiry to consider Contact Energy's proposal for a 220MW geothermal power station at Te Mihi near Taupo.
The board will consider submissions on Contact's resource consent application for the $500 million plant, hold a public meeting and make a final decision on the proposal.
The company plans to have the geothermal plant producing electricity by 2011. Contact will lobby for the same fast-track process for a second geothermal plant in the Tauhara steamfield.
The two would cost Contact about $1 billion to develop in the next five years.
Sounds good that they seem to have considerable plans to move us away from hydro/gas towards hydro/geo.

Geothermal is a logical choice for NZ which already generates 69% of its electricity from renewables. Mighty River Power is trying to install 60 giant turbines in Palmerston North's water supply and last significant stand of native forest. The locals are very angry at this environmental vandalism. Wind turbines have their place but not at any cost.

This is one area where I have some expertise. I think this is a good summary and introduction to this important energy source.
Geothermal Energy Sources 101
Quote:
Geothermal power plants are an almost pollution free source of electricity. Typically they are installed near shallow subsurface sources of steam and/or hot water characterized by faults, seismic activity, earthquakes and volcanoes.
The source of geothermal power generation is steam at a temperature of ~300 degree C. To access geothermal steam involves drilling a vertical well to the source. A second well is drilled to the lower water level of the steam source. The steam is directed into a steam turbine which in turn generates electricity. The condensed turbine exhaust is re-injected back into the underground reservoir.
There are essentially three types of geothermal power plants used depending on the source.
On dry land and free of volcanic activity, the temperature is typically 41 degrees C higher for every 1.6 km below the surface. With a well drilled to a depth of 3 to 10 kms, steam can be successfully produced from water upon contact with subsurface rock. Steam produced in this manner is known as an Enhanced Geothermal System [EGS] and sometimes referred to as a Hot Dry Rock [HDR] system.
A 2006 MIT report suggests that there is enough hard {hot} rock at a 10 km depth in the United States subsurface, to supply the entire world's energy requirements for 30,000 years.
To produce a sustainable source of steam, the HDR system requires sufficient heat at a subsurface depth, a hard rock layer capable of being fractured, an insulating layer above it and a source of water.

Exploring the Mid-Atlantic Ridge for geothermal energy could be the next great frontier.
Mid-Atlantic Ridge , submerged volcanic mountain range that bisects the Atlantic Ocean along its north-south axis. The range covers the middle third of the ocean basin , running for 15,000 km (9,300 mi) through the North and South Atlantic, It is part of the submerged volcanic mountain range that encircles the earth , measuring some 65,000 km (40,000 mi) long.

We could tap this heat energy to produce electricity to electrolyze water to produce hydrogen. Even if the process had an efficiency rating of 20%, 20% of an infinite energy supply is still infinite.
At the bottom of the ocean near these volcanic events the seawater temperature is at or above boiling and just feet above this the seawater is near freezing. This creates a huge temperature differential, which could be tapped to produce all the electric power we would ever need.
Here are a few examples of Thermo-Electric Generators developed in the 1800’s. Today we have Thermo-Electric Generators that are far more efficient.

I like the idea of conservation and the use of other forms of energy wherever we can will help in the short term but in the long term we need to be thinking in BIG terms.
