    🌤Hi Sunshine, I think your way of thinking about Energy might have some problems with development, but this is my opinion an no one else's. To rely on capitalism to develop nuclear fusion may lead to a pathway to Human destruction. Using the Energy of the Planet with total agreement of the Earth's occupants may be a better solution for the Planet an it's Occupants, again just my opinion. Do you know anything about the Energies that can be produced by Pyramids?

    The conclusion here is pretty much nonsense. Spending more money on a reactor does not automatically make a better reactor, and there are many many lines of fusion research that are still ongoing. We _will_ have a practical fusion reactor within the current century, but there are also many practical problems that need to be worked out, and even when we discover something new or useful, testing those discoveries requires constructing a new test reactor which takes both money and time. In turn, only designs which show a high degree of promise or which would allow us to learn many new things actually get considered to be funded and constructed.
    Scientists are often very bad about wasting money, and fusion reactor research is so expensive that it could easily burn the world's economy into the ground without producing any result, which is why we have to be very selective about what we waste taxpayer dollars pursuing.

    There's literally no reason to think the balance of "energy spent" to "energy gained" would ever shift and so is the "promise" of "unlimited energy" a lie that's so "too good to be true" it makes Santa Claus look like a genuinely proven daily phenomenon.
    How about just promote nuclear powerplants for now instead of coal and all the other nasty ones, use clean energy as back-up and just clean-up the rest of our environment like the cars and planes and yachts.

      Proven oil reserves now stand at around 1.7 trillion barrels. At current rate of consumption, we'll exhaust it in a little over 50 years. Taking the fact that oil companies tend to overestimate their assets in order to inflate their stock portfolio and consumption is still on the rise, it could be even less. Global natural gas reserves are in the same situation. Coal will last us for at least century, maybe less if the remaining coal is diverted to produce hydrocarbon products that once came from crude oil. Either way, a crash in supply is coming within the next four decades.

    • kovona

      Uncontrolled fusion initiation is waay easier to attain than controlled ones that can be harness for power generation. Thermonuclear devices simply use a powerful fission explosion to kickstart the fusion reaction. We are getting closer with controlled fusion, ITER is expected to reach or surpass zero net in 20 years. Than we have another 20 years to make fusion energy practical before fossil fuels run dry...

    Let me get this straight. Build star on earth spending billions. Make energy. Spend millions to erect 10's thousand of kiliometers of cables all over country to distribute energy. Spend millions to maintain distribution system. Isn't there already a star way far away in space where it cost no money and is already FREE. And the energy from it falling all around us for FREE, in unlimited quantities, for the next millions of years???? The same amount of money spent towards fusion technology could accelerate R&D on solar panels making them close to 100% efficient and 1/100th the cost, and still probably buy a set for every family on earth.

      Only a very small amount of the sun's rays hit the earth. Not to talk about the poles. It's possible, but probably not the best solution

    • kovona
      kovona 11 days ago

      The problem is storing that energy and making it available when the sun is not there in the sky. Solar cells are already cheap to make, but the storage systems that make them usable on demand are not. To build a 12 hour grid battery large enough to power a large city like Dallas will cost upwards of $400 million with existing technology. Pumped hydro will cost half that to build and have much less upkeep/overhaul costs, but can't be built everywhere. Both fusion and solar have their own merits and shortcomings.

    The problem is not solely cost, but the energy needed to get to the right temperature is higher than the energy we would harvest from it. There is a quite considerable amount of wrong info in this video (like saying that nuclear is bad for the environment, and showing explosions during a meltdown), but I don't know enough to explain why.
    Tbh, this video falls in the category of vids that I don't know if I should hit the like or the dislike, because it has a good production quality but the info is simply not right.

    • IExist
      IExist 7 days ago

      Uhm, that's what they said. Right now we don't have efficient enough systems to gain energy from the process. But that's why we need to spend money on research for it.
      The sun manages to make energy from fusion, it's possible, if that's what you're thinking

  • Luke AOD

    1:33 "and releasing energy in the process". I can't find an actual scientific explnation of whats actually going on. On an atomic level what actually happens? Does it give up subatomic particles or something?

    • kovona
      kovona 11 days ago +1

      I'll give it a shot. In fusion reaction between deuterium and tritium, a deuterium nucleus (1 proton + 1 neutron) are bought close enough to merge with a tritium nucleus (1 proton + 2 neutron). The result is two protons + two neutrons hook up to form a new type of nucleus (that of helium-4), while a free neutron gets kicked out of the party. By some virtue of physics voodoo (nuclear binding energy), the resulting helium-4 is actually *slightly* lighter in mass than the actual weight of the 2 neutrons + 2 protons that went in to make it. So you expect 2 +2 = 4, but it actually equals 3.98. The missing 0.02 of missing mass has been converted into energy. A very large amount of energy.

    What people forget when they talk about "nuclear waste" is that it is less radioactive than the nuclear fuel we mined out of the ground in the first place. We can put it literally where we found the original nuclear fuel, only now there would be less radiation in said mine because of most of it being used up by humans to produce energy. Nuclear is not a renewable resource, but a limited quantity fuel we take out of the ground, just like petrol.

    Cost is everything. If what the video says is true and the energy is unlimited at no further cost eventually they won't make money from it then the energy industry will almost become dead.

    • IExist
      IExist 7 days ago

      It's not unlimited with no further cost.
      It will cost money to mine helium-3. It will cost a little bit of money to pump water and get the needed atoms. It will cost money to operate the reactors and maintain them.
      Helium-3 and the water isotopes will eventually run out. But so will the sun. So they're basically unlimited, but technically not.

    4 realise there is loads on the moon
    5 we go to the moon
    6 we make a moon base
    7 we mine for a few years
    8 we bring it all back to earth
    9 we extract the hydrogen
    10 bang fusion
    11 we use it to propel our space craft
    12 we colonize the solar system
    13 we rule the galaxy.
