Wouldn't it be possible to drill a hole 100 km deep and take advantage of the thermal energy to produce electricity (of abundance)? There's ALOT of energy down there!
We're taking it one step at a time. 10-12 km is the new deep. And yes, there is infinite energy down there.
Yes, isn't the rock easier to dig the deeper you get? Perhaps not, because of pressure? I would think that a "robot digger" could achieve it, like a worm only displacing the soil and rock behind it as it digs deeper, only leaving behind a thick cable (or two if the robot needs external energy) of course the robot would have to have this cable enrolled within itself...but some solution should be able to achieve that, no matter the size of the robot, since the energy wasted by the robot digging would be achieved worthwhile as it gets there. Hmmm...I thought you meant that there is infinite energy in a symbolic way...but something tells me that this is not what you meant?
Thank you for the tip. They dig a hole in the ground and lead the heat to the ground, which is inefficient, instead they should build in the harvester of heat in the device that is close to the heat and bring the electricity generated through cable to the ground. It gets to cold when it reaches the ground to extract the amount of electricity that could be extracted. Also the "digger" should cover the ground digged before it like a worm does so that we don't trigger a outburst of preassure or something.
Well, you can't extract heat directly from a hot environment. You get energy by moving heat from a hot place to a cold place.
probably would,but at what cost? theres plenty of cheaper easily accessible energy such as wind, solar, hydro electric dams, coal..and even tar sands..
We've been doing that for over nearly two decades here in Hawaii. Check out Puna Geothermal Ventures. Not quite as deep as you suggest, however. Two bores have water sent down, converted to steam, and sent up to run turbines. Produces as much as 20% of Hawaii island's electricity needs. Problems with Sulfur gas emissions, however, require a restriction zone around the bore due to occasional blowouts, etc. Electricity cost is presenntly about triple the cost for burning, oil, etc., though on par with local island costs. Bio-oil might be cheaper in the long run.
Yeah, I'll let you know Please Register or Log in to view the hidden image! or you hear it in the news Please Register or Log in to view the hidden image!
You might be right, I guess it would be hard to dig when the soil gets compressed at large depths, but if we could find the way around that then it might be a nice alternative.
