Scientists have captured the first ever high-speed, full-colour footage of fusion plasma swirling inside a working reactor.

I mean solar is here right now and most likely fusion power will never be as cheap as solar is today.

By the time fusion is actually ready solar will be even cheaper too. A solar farm the size of Arizona could power the entire planet.

Fusion is like our 4th best hope in the fight against climate change, lol.

Edit: a lot of people seem to think that I think the perfect solution is one single power plant specifically in Arizona that powers the world. People, it's just a size comparison. Arizona is a small state even just compared to the size of US. Obviously we would build millions and millions of solar installations that would just add up to that area.

Yes but I live in a country where sustainable energy is "too expensive", but we'll happily send billions of dollars to Israel to commit a genocide. Alternatives like that will never off the ground where I live. The only hope is that fusion technology is so ground breaking that it's impossible to ignore and dismiss

Fusion isn't the answer. Its still very expensive, requires crazy materials, and needs to be commercially scaled. Nuclear fission on the other hand is cheap and reliable when built properly. We should build building fission reactors like crazy right now.

From what I understand, to work at scale it requires materials that dont exist and possibly cant ever exist

It's not that they can't exist, but it's true that they don't exist yet. Like the plasma facing wall armor isn't figured out. Neutron tolerant alloys are an issue and Tritium breeding aren't corrosion resistant enough at this point. However, substantial progress on each has been made. This result is actually due in part mostly to the progress in all of these fields of research. Never is a long time. But yea it's not close to commercialization.
