Don't know if the scientist on these Fusion reactors watch videos like this but a quick slightly uneducated suggestion but how about taking the pellets less use for the laser Fusion and creating a shaped like a dodecahedron and giving it a massive rotation while also heating it up at the same time with the lasers will help to get a even distribution of heat and pressure to help it undergo a fusion because it seems that rotation plays a huge roll in something like the Sun where fusion occurs often or it's just me that thinks that rotation please roll and evenly Distributing heat and pressure to an object but anyways hope this helps on the quest to better energy for all of us

Unfortunately, fusion is a pipe dream and a great way it keeps physicists employed, at least for the next several hundred years. The “machine” would have to be huge, miles across to be viable. The second problem is extracting the energy. So much of chambers surface area is dedicated to containing the event that there is inadequate area left for energy absorption. Our efforts are better spent on LFTR reactors.

Uranium is now a renewable resource, search it up. We've got unlimited supplies now and it's even commercially viable. How's that for a plot twist! "Nuclear waste" is still 99% uranium which can be used in special reactors to generate even more energy until the fuel effectively disappears.

The enemy comes from turning hydrogen into helium. It's kinda hard to explain, but basically there's energy stored in all atoms, but it is not the same. Iron has the lowest amount of energy storage, hydrogen has the most. So turning hydrogen into helium means less energy needs to be stored, that energy is then released.

It's like humans making wheels for pottery and only later realizing that you can make a vehicle with them...something that seems very basic and obvious in retrospect. Humanity has had the tools and technology to make efficient fusion reactors for roughly 50 years now, and not the water boiling cop-outs that people are aiming for. It's equal parts frustrating and amusing to be able to watch this slow crawl and not being allowed to interfere.... Time is funny.

Nuclear Fusion does produce radioactive waste... it releases neutrons that bombard a shield making it radioactive. Yes its better than fission as its only hundreds of years long instead of 10,000 years.... There is a Fusion plant that could power the plant already... its called the sun.... way easier and now.

correction: you said they blast it with a beam of neutrons, that's not what "neutral beam injection" is. it's actually way cooler! they put duterium nuclei (proton+neutron) in a particle accelerator, but since the nucleus is positively charged, it can't penetrate the magnetic confinement. so they fire electrons at the nuclei while they're going top speed, towards the inside of the reactor, so it becomes a neutral composite particle (a whole atom) that deposits its kinetic energy in the center of the reactor when it bumps into the plasma inside, and the beam de-couples into plasma once inside. so imagine, you're running 100mph towards a brick wall, and then at the last second somebody fires something at you that turns you into a ghost so you can move straight through the wall

Thorium is everywhere, the reactors are cheap and it generates much less wast and is self extinguishing in a catastrophe. The containment for fusion is not simple. The elements are rare and expensive. Eventually a fusion reactor will be feasible, until then we should use thorium reactors. PS: Thorium reactors are not encouraged by the governments because it does not generate weapon grade nuclear wast.

Because the sun is electric and not gravitational...gravity is magnetism...the reason why you can see a star behind the Sun during an eclipse is not because of space being warped...but because the light from the star behind the Sun gets repelled around the Sun because light repels light and 2 separate photons can not occupy the same space..Big Bang only explains 4 % of the universe and the rest is dark matter and dark energy or another words...

The benchmark is producing energy at a cost that's equal or less than the current sources of energy. If you're spending billions to produce a few MW of energy, when you can spend millions to produce GW of energy, then fusion isn't worth it. I'm sure that one day we'll get there, but maybe in another 30 years ;p

Thermonuclear bombs are still mostly atomic bombs. They use the second fusion stage to generate neutrons which causes fast fission (i.e. more complete fission that otherwise possible) in a third fission stage. Most of the energy released by a thermonuclear bomb is from fission. The exception is the Tsar Bomba which had it's third uranium stage removed at the last minute. As originally designed it was supposed to be 100 megatons but even the soviets got nervous about that.

Lets say for arguments sake, that these experiments, over decades, have cost in the order of some trillions of dollars, minimum. Where would the human race be today if we had spent that money just on solar and wind? We would have a global solar economy, that's what. We hear talk of problems storing energy but if you were a Roan over 1000 years ago, they would not have even thought twice. Solar farms can pump water by day and the water can flow through generators 24-7, simple hydro power. Add to that possibilities with proven geothermal and we already have a range of effective wind turbines, although far too few horizontal micro turbines suitable for homes and businesses. Electricity is critical to a clean future and the solutions need to be foolproof and have longevity few engineers bother planning for these days.

If we spend all that money on solar and wind we would have an unstable power grid that relies on overpriced gasoline and coal to throttle the supply and keep it from collapsing. Sure, carbon emissions might be lower overall, but at the same time, they are floored with absolutely no viable alternatives to reduce them to zero, in at least a century to come. With all the money in RnD of nuclear fusion we have a reasonable hope to start switching to 100% green power grid within our lifetimes.
