      The delicious irony is that Quaise will be harvesting energy using technology meant for fusion well before the latter will come on-line, assuming it ever does. At that point, simple economics will render fusion (and especially fission) as bankrupt technology. Eventually, Quaise will then supersede the present alternative energy technologies, as well.

    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.

      It is not even about IF this drilling technique will be able to do this but WHEN at least from my limited understanding of this subject. So far it seems not that far off and well withing our lifetimes. Electrification of basically everything would make a lot of sense this way but this also means that we need to do everything we can to protect the infrastructure. Recent solar flare could do in that kind of a world do a lot of damage. This technology can also make all countries completely energy independent. That sounds really sick.

      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 ;)

      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.

    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

      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

    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.

      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.

    One form of geothermal not mentioned is mine water geothermal. No need for fracking when you can use the extensive mined out areas already present. Its much shallower, much cooler, but obviously has huge volumes to work with. Its already in operation in England, with more sites being set up.
    I also wonder if this kind of rock vaporising technology could be given a significant boost by starting in a deep mine, or could even be complimentary to mine water geothermal as a part of the cost cutting with existing infrastructure plans.

      It is correct that the Earth's core would cool slightly faster than it naturally does. But this is a process that has been going on for billions of years and will continue for billions more. And compared to the amount of heat that naturally radiates from the surface into space, I think even tens of thousands of vent holes would not lead to an increase in heat radiation that would be detectable.

    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.

But relying on the vapour knowing where it’s supposed to land will not work.

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.

    Also in the long run we are creating cooling spots as we siphon the thermal energy. This will change the currents of magma layereffect8ng volcanic and possibly techtonic activity....

    Brilliant recycling of old plants that's efficient. It seems like a vacuum would help on the top as a vaporized rock outlet. I'm not sure if the waves will scatter at as depth increases but if so, then a lining can be placed on the side of the walls (e.g. at a max average bore width). I see the cause for the tests and am excited to hear the results! Thank you for the informative video.

    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

    I have been advocating this for so many years! I read up on it, and it is quite expensive (because in places, the heat is well down). BUT...compared to renewables (for which read 'unreliables') and nuclear, it isn't expensive at all! And although wind turbines use truly massive amounts of concrete and steel, and solar panels use toxic chemicals, deep geothermal uses water!

    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.

    Many commenters asked about the vaporized rock condensing before exiting a long borehole. This seems to me to be a very good question. However, I am certain that I recently read about innovative small subsurface tunneling machines that utilize a similar ("laser-like") radiant heating or gas or plasma-based cutting processes in place of rotary cutting blades. I recall they tunneled rather slowly but continuously and, I think, sealed the tunnel wall as they progressed. An alternative method for underground pipes and conduits.

    If we suddenly converted the entire world's power usage to boreholes in the earth's crust. And given that the current year over year increase in power draw remains constant, how much energy would we extract from the earth's core in this time? What impact would that have?

    • @incognitotorpedo42
      @incognitotorpedo42 29 วันที่ผ่านมา

      0.1 percent in 2 million years of use. So basically nothing. The Earth's core is constantly heated by radioactive decay. We're kinda sitting on top of a giant fission reactor.

    • @nathanbanks2354
      @nathanbanks2354 29 วันที่ผ่านมา +1

      I think the heating of the earth is powered largely by radioactive decay, so I don't think it will be a major limitation. It will be similar to tidal energy gradually reducing the speed of the rotation of the planet. The sun getting hotter and engulfing the inner solar system in a couple billion years may be a more pressing issue.

    Drilling is just the first step. Do you rely on the fused walls of the hole to prevent leaks? If you use a bore liner, how do you overcome corrosion and erosion by saline brines at depth? How to prevent mineral deposits building up and clogging the low-pressure side of the system?

  • @robertheinrich2994

    I actually worked in drilling, albeit it being for a short time. 100m a day is possible if it is the upper 1-2km of rock, and if it is sediment. then drilling speed significantly slow down, as the material gets harder.
    but they always drill in some sort of sedimentary rock. not igneous rock.
    igneous rock is much harder and more complicated to drill in.
    but that plasma method is actually capable of drilling in that environment. that's basically the reason why the kola bore hole did take so long. it was so hot and it was hard rock, not some sediment.

    Some important questions that need to be asked and answered.
    1. Should we tap into this energy source?
    Just because we may be able to do something, doesn't mean we should.
    2. What are the potential negative ramifications of extracting and utilizing geothermal energy from the Earth's core?
    3. Would potentially harmful gasses and/or other agents be released into our atmosphere?
    4. Could doing this potentially physically/structurally and/or chemically destabilize the Earth's core?

    One interesting thing is that the average power is limited by the rate of heat diffusion to your borehole. At which pointv they look like hydroelectricity, with a total amount of energy you can take out per year, but it doesn't matter when you take the heat out. it may make sense to use them as peaker plants to fill in the gaps of wind and solar

  • @szkoclaw
    @szkoclaw 28 วันที่ผ่านมา +1

    If you vapourize rock into gas then what happens to the gas when it cools down on the way up? Isn't it going to condense and turn into rock again, settling on the sides of the hole just above the drilling point?

    IT all sounds good on the surface. Issue is we're already having issues in parts of the world where we suck out too much water from underground causing lots of issues.

    Before there were Lasers, there was the Maser - Microwave Amplification by Stimulated Emission.. It produced a collimated beam of microwaves. It sounds like the Gyrotron is similar, though not as collimated, but far more powerful. BTW, the magnetron in a regular microwave oven is simpler, uses a cold cathode, and is much less powerful.

  • @hatac

    There is another technology that needs such drilling but at a much lower depth. The Trompe. These produce compressed air from a low head but continuous water flow. Compressed air can be stored so you get on demand power and can do peak and base load from the renewable. It also requires tiny dams. Carlos Araque is right wind and solar with batteries can't do base load but compressors up the wind mill can, compressed air though solar thermal systems works and compressed air can be stored for a fraction of the cost of batteries. For various reason, mainly the fact that the patents are 100 years old so you can't get exclusivity, the technology has not been developed. The one company that was trying to do compressors up wind mils got bought up and shut down by someone, not big oil. Cheap drilling for Trompe coupled with mass produced parts that can be put down the resulting hole could be significant.

  • @SeattleCoorain

    I believe there was a technology developed in the early 1980's using electrically heated tungsten thermal drill bits to melt thru soil and rock, creating rock-glass borehole linings. Oddly the initial development was funded by the US Interior Parks Dept . The Parks Dept needed to place modern utility conduit runs thru foundation rock walls at old landmark Parks Dept buildings. Their project was successful serving that use case. Somebody realized along the way the same tungsten bore bit might be employed to drill efficiently thru hot rock which as this video points out is very difficult and expensive.
