01 / prediction

These plasmas can last for hundreds or thousands of times the basic theory has shown that now you can have long enough lifetimes. So what that means is in a practical fusion system, there are lifetimes of these high beta pulse systems between 100 microseconds and a few milliseconds, thousandths of a second.

Because this is the other thing that I don’t know that early in my career I’d have predicted, is that by making a hundred of a thing, you can actually make it faster than if you go make one of a thing.

Where it has two neutrons and a proton, and when you fuse those together at very high temperatures, at very high densities or high enough densities and very high temperatures, they make helium, which is a charged particle, which stays inside the campfire, inside the Tokamak, continuing to heat it and stoke the flames, and it makes a neutron which leaves the system because it’s uncharged.

At any one time, in a Helion fusion system and most fusion systems, you have one second of fuel in that system. So what that means is if you stop turning on… If you stop putting fuel into that system, fusion just stops.
