Volcanoes To Be Harnessed For Power

Posted July 31, 2008 2:28 PM

From Science Fiction in the News:

Now that oil-fired power is getting more expensive, it's time to put our boots and spurs on, and tame a real power source - volcanoes! Alaskan volcanoes will be harnessed to power thousands of homes. State officials are set to auction off the exploration rights for Mount Spurr, a 3.4 kilometer-tall stratovolcano in the Aleutian Volcanic Arc of Alaska. Geothermal energy is back on the table in a number of US states, thanks to the high price of oil. "High prices and climate change are definitely creating a renaissance in geothermal interest, particularly on a state and local level," said Karl Gawell, executive director of the Geothermal Energy Association. "If we really want to go all out for it, we could easily achieve a substantial amount, 20, 25 per cent of US energy needs within a few decades. We're limited more by public policy than the resource - the resource is enormous." Crater Peak, one of the two main vents for the Mount Spurr volcano, has erupted twice in the past century. In 2004, the Alaskan Volcano Observatory issued an eruption warning, despite the volcano's status as "Concern Code Green" - a peacefully slumbering giant. SF fans may recall the episode Inferno from Stargate Atlantis, in which a civilization is built within the caldera (eruption crater) of an enormous volcano. The Ancients used the geothermal energy of the volcano to power their city. However, the entire civilization is endangered by the fact that the volcano is heating up, apparently foreshadowing an eruption.

That's interesting.

Here in New Zealand we have been using geothermal power for over 50 years.

Kind Regards....

Yah Sparky,

You guys are just soooo ahead of the curve. I think it must be because of the wizards and Hobbits.

Not only science fiction. Countries that are primarily volcanic in nature have long been producing electricity from trapping steam from volcanoes. A few years ago, I toured a huge geothermal plant in Ormoc, Leyte, Philippines. They use giant "mufflers" over steam vents on the volcano to trap the steam, which is then piped to a central generating plant. The electricity is sent to other islands via under-sea cables. The geothermal industry was actually drilling for steam on Mt. Pinatubo a few months before the major eruption of that mountain. The drilling equipment was eroding faster than normal, and I discussed the presence of increased sulfur oxides with the staff due to the impending eruption. If I remember correctly, something like 20 % of the world's electricity comes from hydropower. Certainly, we can increase the geothermal power production.

I do hope the enviroMENTAList don't think we could do harm to the volcano's or they might not let us tap into them. Plus they are the largest producer of co2. we should not encourage that type of behavior

you opened a w.s.l. of ideas with that one comment.

i cannot imagine how well the groups that follow the paul watson technique for fund raising by tugging at the heart (purse) strings of the public will soonbegin asking supporters to assist a save volcaoes fund. the use of the proven watson method of creating money raising tag lines could be along the lines of

BABY volcanoes are being exploited for profit by greedy people! Help them, now!! By contributing to our EXPLOITED BABY volcano enviromnmental protection fund, thier environment will be protected. PLEASE GIVE!!!

given the monetary successes these and many ngo groups have as track records for u.s. dollar raising through having made efforts claime to having been made in thier "rescuing" of supposedly endangered marine mammals your idea does not seem too far fetched.

Hello barfnagler

Sorry to advise that my Donation Programme is fully committed for the foreseeable future.

The "Save the Baby Volcanoes" coalition is just going to have to manage without me.

Kind Regards....

The volcano is going to produce CO2 and all of the other noxous gasses whether you tap it's energy or not.

If a volcano was a factory it would be shut down by the EPA in a heart beat.

Don't give the powers that be any ideas. The carbon tax that would be placed on the power that is generated from volcano's would be outrageous!

However , when the technology is deployed to tap these thermal " gold mines" I think it will be the next big thing. I am only worried about the after effects that happened to the Hydro power industry with all the impact studies. It was at one time the greatest source of power generation until the fish could not swim up stream. I can see the headlines now; "All this power equipment is preventing the lava from it's natural flow. "

Another quick note: If enough plants were built to tap the geothermal heat from the Earth, over a very long time span, there might be enough "heat" removed from the top few Km of the Earth's surface to moderate Global Warming. Assuming that some carbon dioxide generating power sources were replaced by geothermal energy production. Currently, any steam, geysers, etc are just releasing energy into the atmosphere. This energy could be used to replace coal, oil or natural gas -fired electrical generating power plants.

Hello Cardio07

There is a major flaw in your theory.

When that generated power is used, it is all eventually going to degrade to heat energy.

All you would do, is slightly delay the inevitable heat release.

There is another problem, as the Planet cools slowly, the interior shrinks. This shrinking of the interior, with solidified "rafts" of rocky mantle above, is the "Tectonic Plate" process which drives the crustal plates across the surface, to bump slowly into each other.

Kind Regards....

Interesting. With our technology it seems a very feasible thing to do. Geo-thermal tech has been around for a while,I do not see any reason why we can't tap this natural resource for it's unlimited ability to produce steam for generating power for us.

there is no arguement about any technology using materials that can take the extremly high heat can be used to tap this natural resource, if you care to look at how efficiently it is done my suggestion is to first look at either the icelandic or new zealand geyser projects that work. then ask yourself how is it that the first thing the colonists many countries which had indigenous populations that welcomed colonizing societies show the newly arrived where game was and how to prepare killed / harvested flora and fauna then preserve it knew how to do that the most efficiently using the smoke that thunders. i think it will be pretty hard not to consider the smoke that thunders is could easily refer to a volcanoe or more often a geyser. then next consider how the volcanoe lava when cooled turns to rock, the number of natural body and plant life supporting enhancing minerals a river of lava contains is as i understand it yet to be classified. last item as i understand it coffee trees grow best on the mountains where volcanoes were or are active, if a person wants the garden they have to really push out a healthy load of veggies it is a practice to dump coffee grounds or whole beans in the soil to help break it up, adding timothy buckwheat of good old alflala for the bees will result in huge bean plants, consider the nutrients available to humans and animals in meat bean and quoina dishes. while what i relate is not entirely off topic i use it to relate another as yet mentioned benefit to the benefit and fuel use reductions available through use of geothermal heat sources.
