The study looks into geothermal exploitation of a two-kilometre-long mine shaft, in which the temperature of the rocks 500m below the surface is around 30º C. This is typical of many of the mining areas in Asturias, although it could also be applied to other parts of the world. Water could be forced in through tubes at 7º C and return at 12º C, a big enough heat gain to be of benefit to towns located above the mines.
[ ]…Using geothermal energy also helps to reduce CO2 emissions, and is not dependent upon climatic conditions (unlike other renewable energies such as solar or wind power). Other advantages are that these facilities make use of a country’s own resources, do not require new developments on large sites, do not pollute the immediate environment, and are believed to be profitable over the long term.
The assertions made by two engineers from the University of Oviedo are thus far supported by part mathematical models and part experimental. While we wait for a full scale trial it doesn’t seem too unreasonable to think such a system might work, but in the U.S. and elsewhere some mines are already environmental hazards. The Oviedo researchers did specially point to recently abandoned mines, which one assumes did not pose any imminent environmental hazards while in operation. Environmental complications can include contamination of underground aquifers and surface spillage containing toxins like lead and mercury that drains into rivers and lakes. Then there is the infrastructure that would be tied to creating reliable extraction of the geothermal heat and years of subsequent maintenance. Once the obstacles are considered, geothermal energy from old mines could provide some financial and political incentive to do something with America’s 200,000 to 500,000 abandoned mines ( estimate via Earthworks, see report at bottom). Earthworks estimates the costs to do cap and clean up these old mines would take over $30 billion dollars.
A few short takes: And the Rand Played On – The Going Galt movement protests Obama with a collective shrug.
A Russian émigré who came to America hoping to work in Hollywood, Rand rejected communism but adopted its utopian, dominating aesthetic.
Nothing personal against Rand, I enjoyed The Fountainhead and Atlas Shrugged as a fantasy novels, but using them as a template for a society would be a dystopian nightmare.
She warned listeners of “enslavement to big central government” and the need to “be wary of accepting government largesse.”
[ ]…The data for Sarah Palin’s Alaska is particularly telling. Back in the early 1980’s, Alaska was a net contributor of tax revenue to the federal government in Washington, DC. But in recent years, the state has been the beneficiary of a massive geographic transfer of wealth from the Lower 48. By 2005, Alaska ranked third in feeding at the federal trough, taking in $1.84 from Washington for each dollar sent there. That performance puts Sarah Palin between fellow stimulus refuseniks Haley Barbour of Mississippi ($2.02 payback on each dollar) and Bobby Jindal of Louisiana ($1.78) atop the charts.
I wish that people that live an unhealthy part of their intellectual lives in Lalaland would stop telling other people to stop making things up. Palin is not going to stop seeing herself as the beleaguered martyr anytime soon, which goes hand in hand with her apparent inability to accept the guilt of her hate mongering.
Though it received very little press attention, it is not hyperbole to observe that this October 23 Memo was one of the most significant events in American politics in the last several decades, because it explicitly declared the U.S. Constitution — the Bill of Rights — inoperative inside the U.S., as applied to U.S. citizens. Just read what it said in arguing that neither the Fourth Amendment — nor even the First Amendment — can constrain what the President can do when overseeing “domestic military operations” (I wrote about that Memo when it was released last March and excerpted the most revealing and tyrannical portions: here).
