Memento posted:I consulted for a pilot study on geothermal energy here in Australia in 2013-14 and the end result was the conclusion that there's literally no way it will ever work here. I've been lectured here on "hey why don't we have geothermal power" and "hey why don't we have 100% hydro power" and the answer is that this continent is too old and too cold for geothermal, and hydro needs you to have mountains and rain, and we really have neither. Hydro sure, but what do you mean that the continent is too cold? Ground temp around 30' (~9m) is a constant 55F (~13C) anywhere on the globe. Was it an issue with the cost of well drilling? As fossil fuels get more expensive, that would eventually not be an issue either. E: Actually do you have a link to the study? I'd like to read that. -Zydeco- fucked around with this message at 16:30 on Sep 14, 2018 |

I wonder if he means, like "REAL" geothermal, as in, drilling down to hot springs and such like you're living in Yellowstone, instead of just the normal "the earth is my heat sink" type geothermal.

Yeah I found this which seems to fit the bill and yeah it's about heating water using deep wells rather than as a simple heat reservoir for residential heating.

They haven't had any major volcanic eruption since being settled by white people. There's some native stories about it, but Wikipedia lists the most recent volcanic eruption at 7,000 years ago.

Well, we do have a surplus of hot dry rocks. It's actually pretty cool to see Uluru after a desert rainstorm, was still waterfalls down it a day later.

Was it an issue with the cost of well drilling? As fossil fuels get more expensive, that would eventually not be an issue either. Too cold as in the tectonic sense. All the countries that are exploiting geothermal for power (drilling holes deep enough to hit the hot crystalline basement, pumping water down them and letting it convert to steam to run turbines) are places like Iceland (mantle hotspot on the continental boundary, constant shallow volcanism) and New Zealand (continental boundary, constant shallow volcanism). It's the difference between drilling holes <2km and nearly 5km. Here's a study about the pilot program from 2003 that we worked off to try to get it to work in other places. http://www.ga.gov.au/webtemp/image_cache/GA3681.pdf Most of Australia is made up of rocks that haven't changed much in >1.5 billion years. In that study, the drillhole they used was 4900m deep, 1200m into the granite, which was 240°C at the top (3700m depth). Iceland, for comparison, has rocks that are up to 900°C, at 2100m depth - practically molten. The higher temperature rocks you have the more efficient extracting their geothermal heat is. And the economic analysis of the proposed geothermal plant failed to take into account that the pilot program was in the middle of nowhere, and if they wanted to actually bring that power to market they'd have to build thousands of kilometers of high-tension lines. I think some people are talking about using shallow geothermal to heat their houses, which isn't really an issue in the vast majority of the country. It doesn't get cold enough here to justify it.

I have a feeling that wouldn't work at all, but it seems like it'd be pretty OSHA.

Well the first thing you do to get geothermal power out of rocks is pump millions of litres of water into it. So I think that would shut down Burning Mounting pretty quickly. No, we're pretty happy burning literally the worst coal in the world to feed our power plants. And for a country that gets basically more sun than any other, and has vast uranium reserves and a highly-regulated nuclear fuel supply chain, we generally don't bother with solar and don't have a single nuclear power plant.

It's just what immediately came to mind because I've seen so loving many videos of idiots wrecking their own cars or trucks trying to uproot a stump by tying it to their bumpers. I suppose that's just because the people who chop up or dynamite a stump like you're supposed to don't make it into these sorts of threads.

I'm just being a poo poo. Actually my parents are doing some landscaping right now and they have a few not-large-but-not-small trees to get rid of. Apparently the thing they were told to do, since they don't plan on digging where the stump is going to be outside of a flowerbed or something, is cut the tree off as close to the ground as possible and then have the stump grinded down below ground level, don't even bother trying to dig it out.

Also where are you going to get the water? Solar has to be cleaned, a hidden water cost. Nuclear would be amazing in Australia as it is so geologically stable, plenty of very safe coast line for water that's next to cities. As for natural disasters it's whether the country is on fire or not. It's Australia mate, forget about it.

The guide I saw said to drill some holes in it and fill them with a nitrogen-based fertiliser before applying the mulch. Rot loves nitrogen.
