I love this. It brings back fond memories of Master of Orion tech tree. It is truly SciFi. For example: "Core Waste Dumps take man-made toxic and polluting agents and stash them deep within the planet. Since they’re so far below surface water supplies and often destroyed by the intense pressures and temperatures at the fringe of the molten core, this completely eliminates all Pollution on the planet."

[@williambarnes5023]

We could technically do that today. If we encased our toxic waste in tungsten barrels and threw it in an active volcano, it would sink in the magma through the volcano to the core. The tungsten wouldn't melt until it got way down, and the radioactive molten metals would still be heavier than other elements and would keep sinking.

[@draculakickyourass]

That's the smallest problem. The biggest problem is that cooling the Earth's core makes it rotate slower and eventually stop. The magnetic field around the Earth collapses and we will be exposed to the space radiation. Also the solar winds will barrow the athmosphere and Earth will become Mars 2.0, a lifeless planet.

[@infinite4809]

@@williambarnes5023 that is a really good idea but wasting a precious metal like that would be costly. I suggest putting trash in easily transportable barrels with thermite inside, the barrels can be made from niobium which is around 0.60 cents per gram. it will withstand the heat of the thermite at 2,200C meanwhile plastics will start to decompose at 700-800C. 2,200C would vaporize plastics, aluminium, iron and melt more useful metals like tin to be re-used. after filtering the liquid tin through a system the other waste products will be put into a hydraulic press with their faces cold to freeze the outside of the waste and this process will produce extremely compacted and heavy blocks of trash which can be thrown into volcanos :) Edit: the niobium barrels are reusable btw.

[@hankchinaski4075]

I'm a Geologist with +20 years experience drilling oil and gas wells. As you stated we already can drill hydrothermal wells, butt in geographic locations identified with a high geothermal gradient 100 m/hr for conventional drilling is a gross exaggeration of drilling speeds at the depths you're aiming for. These speeds can be only achieved in upper softer sequences of shales and sands. I was on a well offshore Nile delta that was at the time of drilling the deepest vertical well in the Mediterranean and over 21,000ft. Problems we had on this well at depth was the temperature on the tools in hole kept frying the tools. You need special HP/HT tools as you need them to know a) where you are and b) what your drilling. Limits on my tools at the time was 350F/175 deg C. That is circulating temperature not static bottom hole temperature Then of course you need a fluid in the wellbore (which is your primary well control) with a specific gravity (mud weight) greater than the highest pore pressure of fluids in the wellbore. If not you will have what is call a blowout. So, this technology would have to work at high temps and IN a fluid without vapourising the fluid. Other thoughts are you need seal off sections drilled with steel casing with potentially different pore pressure regimes and having a uniform sized hole is beneficial in running the steel casing. Not sure how uniform a hole this technology would produce. Clearly this technology would be utilised in the base sections with conventional drilling in the upper sections.

[@pin65371]

Yah that is the plan. Drill conventionally to a certain depth before switching to this system. The other thing they will want is to be able to do directional drilling. If they can just move the drilling rig like 10-20 meters and then start drilling again they can bring down costs. That would also bring down the cost of infrastructure at the surface as well. You only build one power plant at the surface that is fed by like a dozen holes that are going in different directions.

[@originalnickname1]

You're 100% right, this technology is taking formation pressure (well control) and cuttings lifting into account not at all. I don't think they're talking about how they plan on holding back formation pressure at all. Vitreous layer that I can't verify the thickness of? I'll watch that particular wellsite from far away.

My napkin math on Quaise: 1MW output, assume beam has 50% efficiency and $0.10 per KWh which is $100 per MWh so around $200 per hour or $4800 per day in just the beams energy cost. If estimates are it takes 100 days to reach depth that's around half a million USD in beam costs to dig the well. Of course... nothing this technically challenging ever goes without a hitch. Looking at the macro investment numbers, assuming a very boring (pun intended) 10 year break even point a 300 MW power plant at 10 cents per KWh would generate 300MWh *1000 * $0.10 *24 * 365.25 * 10 = $2,629,800,000 or about $2.6 billion in revenue. Assuming the operation and maintenance costs are similar to a coal plant (both are steam) they run around $40/MWh so around $12,000 per hour or about $1.05 billion so the cost of the facility construction and sinking the well needs to be under $1.55 billion. The cost of the plant itself (again comparing it to coal) should be around $500 million leaving a budget of about $1 billion to sink the well. Considering an offshore oil well can run around $100 million to sink my napkin numbers for Quaise seem to check out... this is a much better idea than stuff floating around with big investment where the numbers don't make any sense. IF, and that's a very big if... Quaise gets the technology to the point where they can sink wells on existing coal plants and essentially reuse all that investment then Quaise would quickly become one of, if not THE most valuable corporations on the planet. Keep an eye out for that IPO.

[@pin65371]

The other key will be directional drilling. If they can drill a dozen holes in one area it would keep costs down. Alberta is currently in the process of setting up a government funded site to start testing new technologies for geothermal so I'd expect Quaise will end up drilling some holes here. Alberta has an advantage here over many areas since we have all the equipment and qualified drillers required to do work like this. We also have lots of data when it comes to what is under the ground as far as rock goes. They will be able to drill to a certain depth traditionally (which is much faster) and then at a certain point they can switch over to this type of system. That should in theory bring down the costs.

[@theevermind]

Offshore drilling rig rates are ~$500k to ~$1M per day. A single tool rental on that rig can easily be more than the beam energy.

[@otm646]

From my career experience (wellsite geologist) I can say that one of the most important concerns, while drilling a hole, is to (over)balance fluid pressures otherwise there's a high probability of pressure 'blow out' / explosion. The principle method is to use a sufficiently dense drilling/circulating fluid creating a fluid-column pressure sufficient to hold back formation fluid pressures

[@stopthephilosophicalzombie9017]

Do you foresee these fluids making the microwave drilling insurmountable?

[@kimstyles5078]

As a geothermal Wellsite Geologist, with experience of all the challenges, I'm saying that you're very right. Other challenges include high permeability water filled fractures that swamp the beam with more fluid than it can handle/vaporize

[@esbrasill]

The difference being that this geothermal well they will need to drill where there are NO oil or gasformations present. So at worst case you may get some water blowout. On the other hand, fluid or air has to be pumped down the hole to transport material to the surface. Maybe pump air at high pressure trough the waveguide (inner pipe), and fluid around the wave guide at lower pressure (between the inner and outer pipe). At the drill tip the air will blow the fluid away from the beam

[@TraderDan58]

@@esbrasill It’s obvious that a 2 stage program would work best. Use a normal drilling program with casing and cement to protect all the upper zones down to approximately 20,000 ft (6.1 kilometers) then switch to the microwave/laser process to finish the well. The blowout problem is a definite issue. I’d hate to be the guy working the floor when super heated steam comes screaming at my face. 😮

[@esbrasill]

@@TraderDan58 100% agree, but once laser drilling is started you still need mud or some fluid to remove the vaporized rock (i assume this condenses as glass) and to cool the drill pipe. But on the other hand i suppose a clean waveguide is needed all the way up to the bottom of the hole. that's why i proposed the double walled drill pipe to transport air AND fluid to the bottom all at once, The mixture of air+fluid+dirt will the travel up around the outside of the drill pipe, inside the casings

[@MalawisLilleKanal]

There was no mention of what would happen with the vapors as it travels back up the borehole and cools down on the way. I think they could easily clog up the hole or at least slow down the "drilling" considerably.

[@rklauco]

That was exactly my idea. They will need to come up with some solution (e.g. high pressure gas or something) to "push" the vapor up. Or the other way around - seal the hole and create a vacuum and suck it out - low air density will slow down the cooling process... But this will be really difficult over 10km of travel for the gas. Perhaps, if they manage to solidify it under control to small "chunks" and suck/flush them out... I don't know. I bet they already thought about the same thing though ;)

I live in the Netherlands near The Hague. Not far from my home there’s a geothermal installation.

It’s not warm enough to generate electricity but more than warm enough to heat houses.

[@azzanine1710]

While it doesn't generate electricity, that heating has the run on effect of increasing electric grid capacity. If your heating is sorted out by geothermal you don't need to use electricity to warm houses. Also any gas that would be used for heating can go to electricity generation.

Wouldn't the "glassified" walls left behind by the microwave laser eventually (if not immediately) shatter from the surrounding pressure and shifting/asymmetric forces?

[@Yora21]

Like ice, rock does move under high pressure. But I am not sure about the speed. I think eventually a 20cm will close through shifting rock, but if it would take 50 years for a hole to become unusable and needing to be renewed, that wouldn't really be an issue.

[@AllistairNeil]

[@darkally1235]

The problem I see with this method is extraction of the vaporized rock. The only direction the rock vapor can go is back up the multi kilometre borehole, cooling (via heat transfer with the borehole walls and the drill) as it goes. Once it cools enough it will become a liquid and start to drip back down the borehole and eventually solidify - back to relatively the same amount of rock. Heck, what's going to prevent the cooling rock vapor from freezing the drill / waveguide in place? In addition, what's to prevent the vaporized rock from escaping back up the drill / waveguide? There's also the matter of making the drill / waveguide out of a material which won't melt when exposed to 3000+C rock vapor.

The supercritical H2) they propose to produce will dissolve almost everything, very quickly, including all normal alloys of steel and stainless steel. To resist those effects, so-called "high alloy" steel must be used to line the borehole, and that pipe is rather pricey, because it is 60% nickel. But they will not face that problem, because the microwaves they propose to use will not make it down the pipe! The pipe will clog up with condensed rock vapor, among several other issues.

Many commenters asked about the vaporized rock condensing before exiting a long borehole. This seems to me to be a very good question.

This is not a done deal… there are still huge challenges. Vaporised rock might deposit in the inside of the tube, but also on the drilling equipment.

What happens to the rock vapor? Does it settle to take up less space than it started, or does it have to be vented out?

[@IdgaradLyracant]

more importantly they need to remove the rock vapor before it cools. Also the specific heat of the rock vapor is going to cool all the of the hardware on it's way out. Depending on the conductivity of the material eventually the whole 'tube' is going to become an convection oven as they try to get the vaporized rock gas out fast enough not to cook the equipment, two as the plastic point of the rock they won't be able to extract the machine once it reaches that point AND the driving material will have to contend with lateral pressure from sticky plastic-like semi molten material. I am concerned that at that stage where the rock is more like a molten plastic that the gasses could cause massive gas bubbles and the subsequent cavitation could obliterate the equipment ending the whole process. Cavitation in water from what I recall is destructive, cavitation with a billion tons of material involved... this could be an literally GI JOE Cobra supervillain level earthquake machine.

It's one thing vaporizing holes in rock in an open environment in the lab, but once you get down a shaft in the Earth that vaporized rock will deposit higher up the borehole narrowing the borehole. Also you can get to a point where all the microwaves are doing is keeping the current cloud of rock vapour in a vaporized state. There has to be a way of removing the vaporized rock from the borehole order to avoid these situations.

[@CaedenV]

If you are on a subduction zone between 2 plates then maybe... But if you are in the middle of a plate like most of the world is, then this wouldn't be in the top 10 of potential issues. Part of the idea behind this is the faster drill times and cheaper costs to allow you to drill a 2nd hole in a few months if a hole is ruined. Also, once the hole is in use, it is going to be full of pipe and material, so it isn't like it is creating a void that will just collapse on itself without major issues or forces involved.

[@mikelastname]

I feel like the engineering challenges with this approach are less epic than space solar or nuclear fusion. We dig big holes all the time - I imagine setting up a tunnel boring machine on a steep incline and getting 8-9km down (over maybe 50km) without too much issue by having the MASER heads instead of diamond heads , and then setting up a series of galleries down deep with traditional drill and blast, then do the last few km of vertical wells to the geothermal reservoirs with the vertical drill techniques. We can borrow all the smart engineers who built the LHA infrastructure.

[@stopthephilosophicalzombie9017]

Something tells me that "traditional" is the last word that would apply when you are 10-20km below the surface.

[@BlurbFish]

Your proposed 50 km tunnel would be among the world's 30 longest tunnels, while also reaching depths well beyond what a TBM is normally designed for. As far as I know, there's no precedence of getting a person deeper than 4 km underground, yet you seem to propose crewed machines operating "8-9 km down". You think it is easy because you don't understand how difficult it is.

[@mikelastname]

​@@BlurbFish You're right, I don't fully understand how difficult it is. If you have some experience, what would be the challenges? Given we've got a number of mines in the 3-4km deep range, my thoughts were that downwards and sideways bearing pressure at 4 km is going to be similar to that at 10km, and other challenges like logistics are already solved. Most deep holes are mines, and I was guessing that all of the engineering problems are already solved, but the reason we don't have deeper holes is there is currently no point in spending the money due to ore grades not being up to par.

[@BlurbFish]

@@mikelastname The problems with your proposal are the same as those described in this video, and then further amplified by factors inherent to your proposal. You want to drill at a slant instead of vertically downwards, which means overall more km worth of digging in the difficult depth. You need to have crew for the TBM (and the machinery you set up later for the many galleries) at a depth where the temperature is killing. The diameter of a TBM bore hole is enormous compared to that of a bore well, which means more material to remove and higher demands for structural support - the latter becomes more and more challenging to deal with as you go deeper. Again, going deeper becomes more difficult the deeper you are. You propose to get people down to 8 km, even though 4 km has not been achieved.

[@mikelastname]

​@@BlurbFish Thanks, yeah, temperature sure sounds extreme at those depths. I get that widescale geothermal is a very difficult proposition, but putting my dumb ideas aside, for blue sky thinking, I feel like the _engineering_ challenges for this would be less than for say, nuclear fusion where after 50 years of effort, we are a lot further behind where we are with mining engineering.

[@NJL401]

Attenuation in a copper waveguide is, at absolute best, 0.1 dB/m. So by the time the hole is 1 km deep, the 1 MW in the surface will be only 10 kW at depth. 1 dB/m is more realistic at mm wavelengths, making the drilling power 1 kW. That's for a solid metal waveguide. I think this stands no chance.

[@Proud2bmodest]

The microwave generator could be put at the drill head supplied with a high voltage DC source which will have significantly less loss. The trick is miniaturizing the generator to fit in the borehole.

[@davidpacholok8935]

Lowest loss reported for Circular TE01 guide is reported as 1.25 db/KM by S.E.Miller bell systems journal 33:1209-1265 Nov. 1954 But this was C band not mm. Even so 12.5 dB of attenuation delivers only 6% of the incident topside power at max 10km depth, so your point is still valid, even with very opmistic assumptions. Hmmm. I wonder which will melt faster, the rock or the waveguide business end? Lol!

Depending on what value you put on nature, hydro may be a great option in some locations. I'm sure pumped hydro can make sense on some locations where suitable facilities just need some addition for it to work, but on the scale that we need to increase our electricity production in the upcoming decades I have a hard time believing that it will make sense compared to nuclear in general, especially since nuclear already, even with all the penalizing rules, is competitive on a longer time scale. (See the Illinois EnergyProf channel for information about the economics of nuclear.) If we can make this kind of geothermal work, it could potentially be a serious contender though.

(Actual, true event.) Nuclear land demands aren't small. Solar can go on rooftops or as agrisolar in farm fields improving crop conditions. Wind shares land with cattle advantageously to both, and protects coastlines from erosion. Geothermal can fit in under former coal facilities.

They gonna drill up to 10km deep. The radius if the Earth is 6400 km.

[@michaeldepodesta001]

It's not the temperature of the rock that matters it's the heat flux which is the same at every depth (within the drivable layers of the Earth). Drilling deeper gives access to hotter rocks, but if the heat is extracted at a rate which exceeds the upward heat flux, every project is just a one-shot heat extraction for a few years until the rocks cool. Unfortunately the upward heat flux is small in most places. In the UK the average is 0.038 W/m^2 and globally its less than 0.1 W/m^2 almost every where. One-shot cooling of deep rocks may be worth doing, but there will be likely geological consequences of the stresses built up as a blob of deep rock is cooled, and contracts. There are smart techniques for extracting heat from rocks in a genuinely sustainable manner but they involve lateral drilling rather deep drilling. Best wishes Michael

I don't think actively cooling the earth's core is a smart idea since it needs to be molten to make the magnetic field that protects us from the sun. I think they need to find ways to keep it hot not cool it down.

Brilliant recycling of old plants that's efficient. It seems like a vacuum would help on the top as a vaporized rock outlet.

core is rather deeper (and a few thousand degrees hotter) Rock is a _very_ good insulator and one of the most pernicious problems with virtually all existing Geothermal sites is that the extractable heat drops off faster than it can be replenished from below. The collectable area at the bottom needs to be LARGE in order to collect sustainable heat The other problem at 10km is that the rocks start becoming plastic, so your hole may not be stable

Very nice presentation and a great tech. I am a chemist who actually uses gyrotron for microwave generation for dynamic nuclear polarization enhanced nu lear magnetic resonance (DNP NMR). The wave guide is not a simple system if high efficiency is needed at the application point and we usually use threaded (wavelength specific) aluminium or copper pipes. Seeing the need to carry the molten rock out of the drilling point one must use molten salt tech (or something else) as a carrier but than the temperatures may bend or melt the waveguide!

Could they drill with the standard method first until it becomes more cost effective to use the beam?

[@thomassutrina8296]

I did some analysis of Ice Cube and some annular vertical two phase flow analysis. My gut feeling is that heat losses will consume the energy so the efficiency will be in the lower single digit or less. Ice Cube similarly drilled about 80 holes with hot water 2 km into the South Pole ice cap to build a Neutron Telescope. A 10 cm stream of hot water was used to make about a 61 cm diameter hole. Once the hole was drilled they had about a day to install the a string of glass spheres about 46 cm diameter before the hole diameter reduced down from freezing water. As seen the hole diameter is much bigger then the beam in the pictures shown for shallow holes, like Ice Cube. Just like the above stream of water, the rock vapor will turn to a liquid and then a solid slowly to make the glass like surface at a diameter bigger then the beam. And liquid or vapor rock entering the beam will be returned to vapor consuming energy, but maintaining a diameter bigger then the beam. The heat loss in the rubber hose of the hot water in the hose to the OD of the hose is the same effect. I assume the beam is in resonance like a lazar else it is like a flash light that expands at a fixed angle, a cone, useless. And even a lazar has a very very shallow cone angle. This is where the mirror for that wave length comes in to play. Wave guide is metal for this wave length. Rock isn't metal so the property of the glassy rock will change with the rock and is an unknown. The vapor rock is the media in the beam itself, also an unknown spreading effect. And the heat loss conducting the heat from the ID of the hole into the infinite heat sink, an other unknow. I assume to get the present funding all of these losses and effect were modelled. The latter conduction loss has an exact solution, the assumption are the problem with this analysis. The testing goal is to put numbers on the assumptions. So let us assume the hole is drilled. No mention of how water is sent down the hole and vapor comes out. I assume annular flow of which you can find dozens of analysis for vertical annular flow where the fluid is flowing opposite the vapor. Far fewer with heat transfer is occurring to create the vapor or condense the vapor. My guess in doing some of this analysis decades ago is that this doesn't work for such a long hole. That leave the next approach of meeting two holes at the bottom and pumping under pressure liquid down and up with the vapor made in the plant directly or by a heat exchanger. The heat loss to the infinite rock around the is likely for this depth is going to absorb the heat slowly heating the rock nearer the surface of the hole with as diameter increases a lower temperature rise but more area. The conductivity of the rock has to be low enough to make losses low which means at the bottom the reverse is happening to heat the water. My guess is that a very deep large diameter mechanically drilled hole will be needed to provide the insulation to reduce losses for the hot water hole. And the diameter of the drill may also have to increase to increase the ratio of area to perimeter.

[@Crihnoss]

Apologies in advance for the potentially stupid questions: 1) drilling holes and over using heat from the earth core shouldn't speed up its cooling down? 2) if 1 is true.

But I'm concerned about the magnetosphere and continental drift related effects. 3) Where is all the vaporized rock going? I bet that is not healthy to breath or release into the atmosphere.

Well one challenge I see is keeping the losses in the wave-guide low enough. And it is not enough with any material, it must also be able to withstand the temperatures. As a reference for a tv-transmitter operating at about 0.5 GHz the losses in the cable to the antenna was about 3dB for 300 meters. So half the power lost in only 300 meters. Now we are talking 150 GHz and over 10 km.
