@Bomby and Friends I one hundred percent agree. The next big hurdle in public education is making grades K-12 streamable. Anyone in the world would have access to a public education if you could stream grades K-12.

I'm really disappointed by this. hat I wanted to know is how we CONVERT the energy from fusion into a usable form. Same principle as steam turbines, or something else?

Exactly the same as steam turbines. Electricity generation always utilizes turbines unless it's not solar.

The eventual discovery of fusion power could be the reason we haven't spotted any dyson spheres. There's just no reason to.
AV3NG3R00 - преди 2 дни
A Dyson sphere is basically just another type of fusion reactor. It's probably the best type, since it generates quadrillions of times more energy than our biggest power stations, with no need to worry about confinement/heating/cooling/fuel processing and mining etc. All we have to do is build a whole bunch of smart mirrors to orbit our sun, and some way of beaming the energy to somewhere on earth where it can be converted into electrical power. Once we build it, it would be many times more cost effective than terrestrial fusion.

"unlimited energy for everyone" ... who ever owns the first fusion plants will probably become the worlds first trillioinaire. Think about it, how expensive is it to get a cup of sea water vs a barrel of oil... Initial investment will be huge sure but cost of running it seems so cheap you could say its almost free...besides labor, taxes, and cost of replacement parts, and cost of fuel there doesn't seem to be much in the way of operation cost... so where do I invest???

The sun is not a lump of hydrogen gas. High temperatures will only cause atoms to go their separate ways (e.g. outwardly motions). To be honest, the sun produces heat and light through fission on its dense radioisotopes. No doubt that the atmosphere of the sun is enriched with hydrogen and helium gases and this doesn't imply that the sun generates heat and light by fusing hydrogen gas into helium gas. The upper atmosphere of the earth is also enriched with hydrogen and helium gases that derived from proton emission and alpha emission respectively on decaying radioisotopes within the core of the earth. Face this: Einstein's famous equation, E=mc^2 is wrong otherwise garbage also can be used to make nuclear bombs as  long as it is matter or it has mass. Energy and matter can't interchange one another according to Einstein's famous equation. One must have photons before one can emit out photons. Photons are particles and they have mass. All forms of EMWs including light and heat are dynamic photons per volume per time in different saturations. During the detonation of an atomic bomb, gargantuan amount of heat and light have been emitted out. The loss mass during the detonation is equal to all dynamic photons that have been dissipated out during the detonation that released from splitting nuclei of uranium-235 atoms. Therefore without any doubt that photons have mass. Capturing those dynamic photons will cause severe change in momentum therefore a "typhoon-like" winds blew outwardly from the zero-ground. Einstein's famous equation is the foundation of modern physics. If Einstein's famous equation is wrong or not true, this will bring the downfall of the entire modern physics. Fusion is a "bluff"! It only takes place during the last phase of the implosion of the entire universe before Big Bang. Only dense and very dense stable elements will be churned out during the last phase of implosion of the universe. As the universe expanding further, those used-to-be stable elements will eventually turn into radioisotopes after the angular momentum of their nucleons is no longer able to resist the strong repulsive forces among protons within their nuclei. Decaying on those dense radioisotopes will emit out intense heat and light, this will cause the emergence of stars within the universe. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.

Total energy(unlimited!) produced by fussion will finally convert to heat(remember the 2nd law? ) . That will eventually heat up the earth and global warming will be further accelerated. We can bring fuel from moon but how to release the heat from earth without increasing earth's temperature?
Is any body worried on that? Or will solve that later!

What if... just what if, we stopped using so much energy on pointless things and equating quality of life with quantity of stuff. It is absolute insanity that people think our current average uses of energy in daily life make any sense at all. We are people who literally sleep with air conditioning full blast, with blankets. Humans are smart enough to create, But have no concept of limitation or conservation.

To the man who says it's impossible to make a viable fusion reactor, I ask: how do your solar panels work, then (referring to the fact that solar panels run on the energy generated by the sun's ongoing fusion reaction).
If it can be demonstrated in nature, man can replicate it; there is no shortage of information on this.

Could we somehow incorporate a fission reactor too? Get power from fusing then split the atoms apart and get power from that too. Creating a loop.

@Owen so it might be possible just really fucking hard to fuse atoms until they reach that mass. I have heard of an experiment where scientists kept adding subatomic particles to an atom and causing it to get bigger.
Owen - преди 13 дни
Zauce The Sauce Bauce unfortunately not. You only get more energy than you put in below a certain size of atom for fusion, and above for fission. The atoms for fission at in the order of 200+ mass whilst the ones we fuse have a mass of 2-3. The boundary between where fusion effectively works and fission is about 54.
Zauce The Sauce Bauce
Zauce The Sauce Bauce - преди 13 дни
What if we split atoms into the things we then fused? Or just take the unstable atoms left over from fission and try and fuse them then let them split again because it would likely remain unstable.
Owen - преди 13 дни
Zauce The Sauce Bauce no, we don’t fuse into the same atoms we then split

You left out the part where nuclear power works with a fundamentally different (and more efficient by orders of magnitude) force of nature than all traditional and antiquated forms of power generation (which includes solar technology, since solar panels trace back to Einstein's postulation of the photo-electric effect in 1905, predating the nuclear reaction form of power generation).
Going from mechanical/electrochemical forms of power generation to nuclear is switching from electromagnetic/gravitational energy generation, to intra-nuclear manipulation, a fundamentally different (and more efficient) approach; it's the new craze that never caught on, thanks to green peace vegan commies who play too much Fallout!

Angele Pocock - преди 13 дни
@S G Okay, here we go again. 1. You claim that I didn't say anything to that affect. While I didn't outright state it, I implied it, or at least attempted to. Specifically, I meant to imply that people had valid concerns for why they might oppose nuclear technology. People have seen the kind of devastating impact an accident can bring about, both on the environment and on the people, and may be wary of it. These events may be more ingrained in people's minds, and thus make them more wary of adopting something with such devastating potential. Perhaps I shouldn't have been so succinct, and should've expanded on my thoughts a bit more, but with all due respect, I don't see how a lack of clear communication makes me a child, nor gives you the right to insult me, as opposed to doing something more sensible like asking for the aforementioned communication before jumping to conclusions. Communication, after all, is a two way street. 2. I did not 'ignore' your rebuttal. I addressed it. Correct me if I misunderstood, but your rebuttal was, in effect, along the lines of 'All energy leads to loss of life, and oil, coal and natural gas have lead to more death via war than people have died as a result of nuclear disaster.' My rebuttal to that statement was, to quote, "instead of playing the blame game [...] [let's] work towards holding the warmongers accountable and [work to] develop a better energy system..." This is very much an acknowledgement that, yes, current systems are _not_ good enough, and people are dying. This is bad, but I do not believe that nuclear power is the answer. If you don't call that a rebuttal, then I'm sorry, but you've either ignored my point, or you've elected to strawman me to make your sophistry seem stronger than it actually is. 3. The first point of your argument, I might concede to; it's understandable that you might've misunderstood me, given how brief I was in my initial comment. The second part, however, just makes you look hypocritical, given that _you_ ultimately glossed over my argument in favour of an uncalled for personal attack. Furthermore, as I've proved in my prior point, your argument also lacked in substance. Stop being a prat. Learn to discuss, rather than just assert your opinion, because I promise you that you're not going to be swaying anyone to your side by acting like a jackass. It's hurting your cause more than it's helping it.

@S G I'm a child for pointing out that a system is flawed, and you would be better off addressing those flaws rather than blaming an entire group of people for an understandable fear? Yeah, sure. How about, instead of playing the blame game as to why our planet is dying, we work towards holding the warmongers accountable and actually working on developing a better energy system?
