The goal is to get it as hot as McDonald’s coffee
In fusion reactors there is a lot of talk about the temperatures they reach and the time it manages to work, but all this corresponds more to propaganda publications. The real problem is achieving net energy production and at this point they are not much further ahead than the fusion reactor built by a boy in a garage a few years ago. Achieving nuclear fusion is not that complicated, it is complicated to do it by extracting more energy than invested and this is still a minimum of 10 years away.
The main parameter that determines if a fusion reactor generates net power is called its triple product, equal to the product of the plasma density, temperature, and confinement time. So setting records of time spent at operating temperatures is making important progress towards net power production.
It feels like there’s a lot more positive stories coming out about fusion lately :)
Does this contribute to warming the planet? 😁
Testing and stuff probably does by a tiny fraction, because they need to use insane amounts of power to get it started which is probably produced by coal/oil.
But once it’s actually working and producing more power than it consumes it will be the best solution to stopping greenhouse gases for energy production. It would be the end of gas/oil/coal in the energy sector. Probably wouldn’t even need to use solar or wind anymore.
Particularly nuclear fusion, which doesn’t generate long-lived radioactive isotopes as byproducts of energy production. Nuclear fission still has a place to be sure, but once we crack the dilemmas with fusion all bets are off when it comes to generating huge amounts of clean energy.
Fission gets a bad rap. The amount of waste it produces is minuscule compared to the amount of waste generated by fossil fuels, and it’s generally easier to deal with too. Just needs actual proper maintenance and care.
