[...] Engineered geothermal systems (sometimes called ‘enhanced’ geothermal systems) do have limitations. While conventional geothermal power in the United States costs about 10¢ per kilowatt-hour (kWh), comparable to oil and gas, EGS is more like 19¢ per kWh. It should be possible to bringt that down somewhat with increased scale and experience. Also, whereas the 10¢ for coal power fails to take into account the climatic harm associated with that power source, EGS produces no greenhouse gas emissions and emits no atmospheric toxins. Another limitation of EGS is the production of earthquakes, though supporters argue that with proper management it can be ensured that these are always too small to cause harm. [...]

Reykjavik Energy is providing the holes in the ground into which the CO2 will be injected. The firm is also providing the CO2 itself. This CO2 is, ironically, a by-product of geothermal energy, which is normally thought of as an “emissions free” technology. There is, however, a lot of carbon dioxide underground, and when you drill for superheated water to turn your turbines, you often release it. The plan is that instead of being released, the gas will be redissolved in cooler water and injected to a depth of up to 800 metres, into suitable basalt formations where, the hope is, it will react to form calcite or dolomite.

There is one, maybe up to three tops, geothermal projects underway or on the drawing board in Canada, but the federal government -- beyond providing a 1 cent production tax credit -- doesn't seem too interested. Instead, according to Sierra Geothermal CEO Gary Thompson, billions of dollars are being committed to back clean coal and carbon capture/storage technologies while country's such as Germany, which has a similar geography to Canada, are forging ahead with enhanced or "engineered" geothermal systems that make geothermal power production possible in less conventional locations. The U.S. is also heading in this direction, most recently expressed by a planned $90 million investment in enhanced geothermal from the Department of Energy.

Have just been typing for the past three hours, me not spell so good. But I do look good in a pencil skirt, no doubt thats why they keep me on.

Geothermal Makes Me Hot

Having asked both the American ambasador and the Canadian ambassador about their role in bringing this technology with the areas of North America which could utilize Icelandic advancements in this area they were both uninspiring in their responses. Northern British Columbia, specaifically the Nass Valley has vast lava fields reminiscent of Icelandic geography as do areas of California. I know of some aboroginal companies in Canada that have sought to use this technology but further investment is difficult ot obtain as there is a high start-up cost but then an eternal renewable benfit.

Speaking of the eternal, congratulations for obtaining the adamantine chains.

You’ll make the golden handcuffs look good.

Also you may want to watch the South Park episode where they go to Ottawa to meet the new Prime Minister a la Wizard of Oz. I nearly peed myself.
