YouTubeThe Dispatch ran an informative article about OSU starting installation of a second geothermal system on campus. A tight group of large buildings that can share a single large installation is a textbook application of this technology. Give it a read, it's interesting.

http://www.dispatch.com/live/content/local_news/stories/2010/12/23/450-geothermal-wells-to-heat-cool-5-osu-dorms.html?sid=101Am I the only one pleasantly surprised the Dispatch article mentions closed loop systems, which IMHO seems a key concept for addressing our resources challenges ?
See John Jenkins' Humanure Handbook regarding another sort of closed loop system. Aquaponics and composting food scraps is another example.

'closed loop' in this context means: water down=water up.
but thanks for at least trying to keep it classy this time.

Thanks for posting, that was a nice article. I was pumped when I saw them starting on this a few months ago because, among other things, it meant they would (eventually) get rid of that uglyass gravel spot right across from the Union on the edge of the South Oval. I was afraid for a while there it wasn't going to ever be replanted with grass.

From the dispatch article:
The system will cost $4million but will save Ohio State money in the long run, Conlon said. It will use 34percent less energy than the natural-gas system at a savings of $200,000 a year, which will help the university recoup its investment in 121/2 years.
Wonder what recent events will do to that calculation:
U.S. natural gas is poised to extend its biggest annual decline since 2004 as new pipelines from the Rocky Mountains deepen an unprecedented glut of the fuel.
National spot prices at the Henry Hub, the delivery point for New York Mercantile Exchange futures, fell 1.72 cents below those at Opal Hub, Wyoming, the benchmark price for the Rockies, for the first time in a year on Nov. 22. They have averaged 43 cents more than Opal’s so far this year and were as much as $7.52 higher in September 2008.
About 3.8 billion cubic feet a day of gas, equivalent to 6.1 percent of national output, will be able to be pumped next year from states such as Wyoming, home to the nation’s second- largest reserves, to California and Illinois, the U.S.’s second- and fifth-largest consumers, as new pipelines open. U.S. futures have tumbled 26 percent in 2010 as stockpiles climbed to an all- time high for the second consecutive year.

At least they won't be as dependent on natural gas.

I have faint memories from the early 1960s when OSU's McCracken power plant was still coal-fired. There was a rail spur from the CSX line, down Woddy Hayes Drive and over the river, with a set of rails in the center of the road. Once in a while a locomotive would shunt a few coal hopper cars down to the plant, it would stop traffic.
The plant burns natural gas these days but it still pumps steam heat to a lot of the campus.
BTW the 5th Avenue dam was built to create a reservoir of cooling water for the plant, that is no longer needed.
