If God had wanted us to have nearly unlimited clean energy, He would have placed a fusion reactor into the sky. (feddit.org)

I had to laugh at this one lol

I watched a docu about one fusion startup in the US. They're skipping the boiling water step and converting the energy directly to electricity.

I dont remember the mechanics of how though. But they reportedly are the closest to net positive.

Helion energy. But i don't think their approach has been verified yet. So take it with a grain of salt.

I didn't know someone was trying a different approach like that, their animated graphics were really cool.

Eventually someone has gotta figure this out, I just hope I'm alive to see it and the outcome of it.

Can we then use that electricity to power a boiler?

They have been trying to do this for a long time I think and have gotten very close. At least that’s what I thought

I'm old, fusion has been close for decades. Some reactors achieve unity but can't sustain, some can sustain the plasma but don't quite produce a net energy production, and all of them are limited by selection of materials compatible with the sheer radiation of the chamber.

We're frustratingly close, and progress has been made, but I get the feeling it's one of those areas of science where a large breakthrough in either MHD theory or material science is needed to kick fusion from info NG research into practically possible.

Fun Fact: Since 2006-2007 Uruguay’s power infrastructure has mostly relied on green energy, making up over 90% of their power infrastructure, also making them fully self sustaining power wise

In Canada (2023), renewables make up 66% and nuclear 13% (about 80% together). That's also pretty good.

yeah some countries have that, like sweden and austria. the reason is because they're very mountaineous areas, so there's a lot of water power to harvest. in germany, which is really flat, that would have been impossible with water alone.
