-- If anyone has a more accurate/relevant picture to put on this article, it would be much appreciated; I'm pretty sure the current one is a picture of exactly what HDR/EGS is _not_. I'll work on it -- mebbe -- if I can, but my drawing skillz are almost non-existent.Little hacksaw 23:51, 24 June 2007 (UTC)

tar sand[edit]

Has anyone considered using this to extract oil from Canada's tar sands? It would help with the wastewater problem, and, hey, the companies probably know a thing or two about drilling.--Joel 23:25, 29 June 2007 (UTC)

Yes there is a group of companies planning on drilling a test well. It is not expected to be economic because of the depth that you need to drill to in that area of the tar sands. —Preceding unsigned comment added by 24.85.227.218 (talk) 06:44, 2 April 2009 (UTC)

Soultz project[edit]

Please can someone with more technical knowldge than me add information on the Soultz Project, in Alsace, France, also referred to in the Rosemanowes Quarry article? Vernon White . . . Talk 23:27, 26 January 2008 (UTC)

Removing refs and links[edit]

This article looks more advertisement for Australian government. The political messages and ads should be removed in regards to wikipedia international targets. Hidden fact (talk) 03:29, 8 January 2011 (UTC)

I am removing one reference and all external links for these reasons;

Problems with references;

Reference 1 broken link; http://geothermal.inel.gov/publications/future_of_geothermal_energy.pdf Removed

Ref 2: An australian politition *mentions* 'hot rocks', and that's about it. Nothing about the earthquake that the citation is supposed to back up. http://www.abc.net.au/lateline/content/2007/s1938273.htm left in for now

Claums to be government - "US Dept of Energy" ? Not sure

No idea why this is here. —Preceding unsigned comment added by Chzz (talkcontribs) 03:06, 14 May 2008 (UTC) Đ

MEGS?[edit]

The section at the bottom of the page titled "Modular Enhanced Geothermal Systems (MEGS)" is unreferenced, uninformative and poorly written. I suggest that it be either improved or deleted. --Dwane E Anderson (talk) 01:58, 15 December 2008 (UTC)

Whatt is on google on MEGS leads me to think its a spoof or a spam and we would be better ff without it! Vernon White . . . Talk 12:09, 15 December 2008 (UTC)


Also the article incorrectly states that the MIT report says that EGS can produce free electricity. —Preceding unsigned comment added by 24.85.227.218 (talk) 06:46, 2 April 2009 (UTC)

Additional risks needing coverage[edit]

The article talks about increased seismic risk, which are certainly earthshaking, but has no mention of other risks. Someone with good references or expert knowledge needs to add information about these. Many of the sites are in locations that do not have enough water resources to meet present or planned future needs - It will be a political and engineering issue to get enough water to run these enhanced systems. The water that is injected exceeds the amount of hot water that is recovered for energy production. The difference may impact local water supplies, both underground and surface. This issue will of course be quite different at different sites. The hot water passing through the rocks will leach minerals and bring them to the surface. These minerals may include heavy metals, sulfur compounds and chlorine compounds that must either be removed at additional expense or proven harmless, also an expensive process. Only political pressure will ensure that the tainted water doesn't just get dumped. Chiverisimilidude (talk) 01:05, 29 April 2011 (UTC)

Better reference for term Hydroshearing[edit]

An earlier reference for "hydroshearing" can be found in Cladouhos et al., 2009, Toward More Efficient Heat Mining: A Planned Enhanced Geothermal system Demonstration Project, GRC Transactions, Vol. 33, 2009 (http://pubs.geothermal-library.org/lib/grc/1028449.pdf)
