    Yeah. Actually using that heat is the next challenge, I suppose. If I am not mistaken (and I am often mistaken), they are not actually using the reaction to power the reactor yet.

    It’s all math, basically. If they measure more energy coming out than they put in, it’s considered a win.

      How would they use it to power a reactor? Is it like a regular nuclear reactor where you essentially boil water to power a steam turbine?

      I swear a part of my inner child died the day I found out that nuclear reactors are essentially big kettles.

        It’s likely going to create steam, just like a reactor today. It is a very effective way to turn a turbine for a generator, after all. All the bits that actually start and maintain the reaction need fuck tons of electricity, so the reaction can literally power itself when attached to a generator.

        While there are a ton of formulas for converting energy from heat, to steam, to mechanical energy and then into electricity, it’s all basically the same: more power out than you put in is a good reaction.

        Almost forgot, water is dual function. It cools the equipment and it acts as an energy transport. I believe ammonia is more efficient in some circumstances, but water is better for obvious reasons.

          Yeah, I mean it makes sense. My inner child wants there to be some sort of magic that splits the atomic nucleus (or in the case of fusion… well you know) and harnesses the energy through some sort of fancy magical-to-us-commonfolk process.

          Kettles are great, but not whimsical or fantastic.

            How the heat is generated is still wicked-cool and is basically magic. Think about it this way: We are holding a toroid shaped micro-sun in place with magnets. Those magnets need to be adjusted hundreds of times a second to keep everything in its place. Sure, it just boils water, but how it boils water is where the real magic is.

            We are building atoms by taking control of the core of a star.

              That’s fair! I’m not trying to downplay the accomplishment at all. In that way even nuclear fission is really cool.

              It was just a big dissilusionment moment for me way back when I learned how the electricity is actually generated.
