Le duke Posted December 14, 2022 Share Posted December 14, 2022 Kind of amazing there isn’t a thread about this. This is flight, the atomic bomb, the moon landing and the internet combined. Potentially the most important scientific achievement, ever. https://youtu.be/njPoLi7j-gU Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

What would be better for them than an infinite supply of energy they don’t have to drill for? They don’t have to buy/lease land, deal with spills, and go from villain to hero.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

They need scarcity and capex heavy extraction as barriers to entry for their business models to work. 2 Link to comment Share on other sites More sharing options...

Ban Basketball Posted December 14, 2022 Share Posted December 14, 2022 I know that I could Google it, but I already did and didn't get a suffice answer, nor have I ever taken a physics class. I know that fission is what we use now, with the big drawback being waste. With fusion, I've always understood that it will apparently be clean, but the big drawback is that the chain reaction cannot be controlled. I think I assumed we already knew how to fuse the atoms, being "how to control" the reaction was all that I heard as the drawback. Obviously, we had yet to figure out how to fuse. I haven't read A THING about how they plan to control it, if my memory serves me right regarding this drawback. So, did I hear the "control" part wrong, or will that still be a concern?

Ban Basketball Posted December 14, 2022 Share Posted December 14, 2022 This assumes that the reaction can be controlled, but, on another note, it ought to be something to watch our energy companies, always looking out for us, mind you, cook up their propaganda machines to tell us why we mustn't use this form of energy. Just as how wind and solar energy are devils in a woodpile. 1 Owner of over two decades of the most dangerous words on the internet!

mspart Posted December 14, 2022 Share Posted December 14, 2022 My dad was in his thermodynamics class in college when nuclear energy was first happening. His teacher was distraught because that would mean steam would not long be in the equation. Well, he found out the heat from the fission reaction heated up the water and made steam and he was vindicated. Will fusion take the same path? Still use water to drive a turbine? Fusing two Hydrogen atoms together releases a heck of a lot of energy in the form of heat. It is carbon neutral but produces Helium. Will that be a new contaminate that we will have to mitigate? How to control the amount of heat produced will be the real turning point. In order to start off a fusion reaction, you have to introduce a lot of energy (hence the use of lasers), but once it gets going, how do you control it. Feed in a few hydrogen atoms at a time? They are pretty small and tough to meter out just so. I think this is a great advancement for us, but will it replace the energy source for trains, ships, and trucks? Certainly it can replace the sources of energy we use to make electricity, but electricity is not that efficient or effective for transportation of a truck or train. Unless we run electric in all the roads so we have endless driving, similar to trolleys and electric buses with the electric lines overhead. If we have Mr. Fusion, then that might just work. mspart Link to comment Share on other sites More sharing options...
Mike Parrish Posted December 14, 2022 Share Posted December 14, 2022 The two biggest engineering problems for fusion that I'm aware of are: * controlling the extreme magnetic fields necessary to keep the plasma away from the physical walls of the reactor * material science issues with the plasma eating away at the containment structure Link to comment Share on other sites More sharing options...
mspart Posted December 14, 2022 Share Posted December 14, 2022 Someone wrote somewhere that there is no containment issues. Yeah right. Radioactivity won't leak out but temperatures of the sun will. mspart Link to comment Share on other sites More sharing options...

In a fission reactor, the fuel itself is radioactive, as are the byproducts. In a fusion reactor, nothing is radioactive. It's just really hot.
