48 seconds. I predict a glut of helium. balloons for everyone

I'd like to know more. How do you actually harness the energy produced by temperatures that high? Is the end goal to figure out how to sustain the reaction at lower temperatures or do we actually have ways to generate electricity from those temperatures without losing most of it to waste?
- I think the current designs would all use radiation heat, which means infrared etc light hitting the reactor walls and a coolant (water) running through them to generate steam, and then it's the good old turbine to electricity process... Light emitted from a plasma that hot isn't that hot itself / wouldn't heat reactor walls to the same temps.
- Same as with almost any other reactor: Steam running through turbines. The high temperatures are important to sustain the fusion process. The goal is that it practically self sustains itself while we just continue to feed it with hydrogen.
  
  Why not magnets
  
  How do those work?
  
  Nobody knows
- Whey do you mean? Everything is just stream!
