I know they are working on different reactors, but what's the current problems? What are they trying to reach?

Fission is clean, only a few paranoid people go apeshit over it.

Fusion, theoretically, provides more energy but they still haven't managed to create a stable and energy-positive reactor.

>what's the current problems? What are they trying to reach?
Confinement that is strong enough, stable enough, hot enough, and lasts long enough to actually generate net power. There's lots of weird aspects to plasma dynamics to address, sufficiently strong confinement schemes haven't been demonstrated yet, and plasma heating needs to be in a crazy regime without disrupting the confinement or dynamics. They're making lots of progress on the dynamics, and the latest generations of reactors are basically different ways of optimizing for the problems listed above.

Big government money is all tied up in the ITER project that takes ages to complete.
Technology has advanced since, but there's only like 2 start-ups trying to take advantage of it right now, since again - all the big money is already bound up in this decades old project that's at least a decade over its deadline.
I mean ITER will still work, but it's kinda frustrating just watching them pour cement for 10 years without making any advances.
Well I guess there's still a bunch of test reactors making interesting new theoretical advancements. But most of that stuff is literally just meant to be tested in ITER at the end of the day.
So, really it all rides on that mess.

They aren't. Obsolescence requires something newer to replace it for a similar role or function. An outdated bespoke solution that gets replaced with an inexpensive, generic but lower performance solution involves a lot of outdated hardware, but none of it is obsolete.

Every single online dictionary I found lists "outdated" as a synonym to "obsolete".

>> No.10048290

obsolete implies that a technology can longer perform to some minimum contemporary specification. outdated implies that while it satisfies that specification it is not the optimal technology.

doesnt matter what it implies or sounds like in your head

the words are almost exactly similar in their meaning

>> No.10048324

>>10048273
There are more recent designs out there and it's not like ITER is even close to being operational (even though ITER will probably be completed first), so I'm not sure if your point applies currently. But I do agree that outdated is the better term here.
>>10048290
I'd argue that the two can be used interchangeably (as they indeed are synonyms), even though, as you correctly say, the subtle implications are different and outdated is the more proper term in this context.

Since you mention it, do we even know if ITER will be able to perform up to specification?

no one is willing to spend the money it would take to build it

im absolutely convinced that if the american government diverted 15% of its annual military budget ($639.1 billion*0.15= $95.865 billion = $95,865,000,000)

yes 15% of the annual military budget is $95,865,000,000.

if we spent that much per year for a decade we could build a fuck you sized fusion reactor in every state.

but no, we have to kill sand niggers who worship the same god we do incorrectly, and also something something oil, and something something corrupt sellout to the military industrial complex.

If the US loses this status, they will no longer be able to run the deficits they are, and the nation will instantly implode

Yeah, people are so paranoid, it's not as though a meltdown renders an area unable to be lived in due to high radiation for decades. It's not as though half the ocean wasn't contaminated. It's not clean, the wastes it produces can have very long half lives. With that being said, I'm personally fine with fission reactors as long as you put them away from the ocean.

we could just threaten to nuke everyone if they abandon the US dollar as the reserve currency. Since your argument is that we threaten them with our military to achieve the same goal i suggest we just go strait to the big stick and get rid of the unnecessary window dressing.

there is effectively nothing the nuclear threat doesnt accomplish that the military threat does.

If you have a look at the calculations, the energy that can be harvested from a single helium or hydrogen atom fusing is like 20x as much as can be harvested from breaking an uranium atom. I realise right now it takes a lot of energy to fuse atoms, and that makes it not worth it. But we should be striving for fusion.

Even in the most optimistic scenario the first experimental fusion power plant could be build in 2060. And it would be in China.
