Above you can see the glowing plasma of a tokamak machine which has become iconic through popularization of fusion by various science fiction movies, series and books that employ fusion tokamaks as a source of energy on spaceships and other future devices.
At the same time tokamaks like ITER have become also iconic as ITER has become the slowest enginnering project humanity has ever undertaken, being under various stages of design and construction from the early eighties of the previous century.
Humanity needs fusion energy as soon as possible to shake its dependece of the fossil fuels. But the size and complexity of magnetic confinement tokamaks make them a very long term investments. At the same time inertial confinement fusion energy has never really gotten of the ground.
But a relatively new magnetic confinement machine called a stellarator has recently gained some traction. Are stellarators alternatives to tokamaks?

Hi,
Thanks for another question about this fascinating subject.
One comment is that maybe the title seems to canvass a bit too much nuclear fusion as the solution to our atmospheric pollution.
Is the intent of the question to compare nuclear fusion as a source of energy vs other "clean" sources of energy, such as renewable?
I assume that nuclear fusion does come with some drawbacks as well, such as the need for cooling and the warming up of rivers?
Maybe a title such as:
"What are the advantages as disadvantages of nuclear fusion compared to renewable sources?"
would be more neutral?
Thanks again. Looking forward to the answers!

I really like your suggestion for the title. I will change it as soon as I get access to my computer.
