I remember hearing when it was announced last that fusion was achieved, scientists were skeptical that we had finally achieved this and we wouldn’t be actually putting it to use for decades to come.
But here we are. Yes it’s experimental but it’s working amd producing energy. I’m just surprised we’re here already, even if it’s only a proof of concept at this point
IAEA’s estimate is that Nuclear fusion, if successfully researched and demonstrated at full capacity within 2036 at ITER (which is already lagging behind schedule) will result in commercial availability in 2050. So yes, we are still decades away from putting it to use.
Thanks for the explanation
If this how we get Godzilla?
No. When this how we get Godzilla.
But. Godzilla then how he got?
No we get Gozilla when we mine for underwater Tritium deposits using small nukes.
Fusion is so dump. Were at least a couple decades away from brake even in the fusion reaction, but still people believe it will help solve the climate crisis.
Atm we put about 10 times nore energy into the whole system than we get out. And it generates nuclear waste because the wall materials absorb neutrons and get radioactive. And so many other unsolved problems… this technology is a nice research peoject, but none of us will ever see a commercial reactor in action, because it is so far away, if even possible.
So what? People should stop trying for a better tomorrow because today sucks?
No. Renewables are available and super cheap.
They are, and they are good solution but they are not good all and end all solutions, both wind and solar cannot meet baseload and when you start talking about battery storage as solution, scaling it up requires more metal mining than will ever be sustainable, so pursuit of fusion, pursuit of tidal energy, pursuit of better nuclear, pursuit of better geothermal are viable exploration options as we need baseload generation substitute.
You do not need batteries to store potential energy. You can pump water up a hill into a reservoir and then harvest the energy when you need it using hydroelectric energy.
Dams are a whole another story ecologically but even leaving that aside, we are talking 200-300GW capacity currently in the world for PHES, even if you construct damns on every possible lakes, estimates are around 1000GW that world can build. World currently consumes close to 8000GW on baseload. We won’t even cover 15% of baseload with PHES.
If you’re trolling with your storage as magical solution keep trolling.
Not sure if you are being willfully obtuse, I’m going to assume good faith.
A dam is a hydroelectric plant. you need a river a ravine and a lot more conditions to be met.
This is what I was talking about: https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity
and technically speaking potential energy could be stored by lifting bolders and then harvest the released energy when they are allowed to come down. There are many ways to device systems like such. You could even go underground and use drilled wells with two reservoirs at different levels for this.
You are mistaken to dismiss this outright without at least looking at the wiki i linked.
I’m not saying storing potential energy doesn’t work, it works and even though we lose some energy in conversion it’s still better than chemical batteries. No question there, my point is simple, we don’t have enough infrastructure to cover the world’s baseload demand by releasing stored energy. We need something that can produce baseload power 24x7. Geothermal and tidal(debatable but close enough) are the only viable renewable energy sources we have that run 24x7 and they’re not enough to cover the world’s energy demands. Adding PSEH doesn’t cover it either. We need something more and nuclear (fission or fusion) are the only other options that don’t emit CO2.
Imagine making this kind of comment in a technology community.
Max Planck plans on building an actual power plant in the 2030s. A stellerator (just like Wendelstein 7X) which, unlike Tokmaks, don’t have scaling issues. They will still need to nail down tritium breeding (ITER not getting anywhere, it should have provided that data) and there’s also some headaches about divertor panels which get (deliberately) hit by plasma and wear down quite a bit quicker than they would’ve hoped but a failure there would only get into the way of being price-competetive with other energy sources (lots of spare parts needed), not achieving net power output. Including cooling and everything, not just plasma heating.
As to it solving the climate crisis: Certainly not on its own, but possibly on the tail end of the transition. We don’t only need to fix the climate issue but also switch to a circular economy and having plenty of cheap energy makes that way, way easier to achieve.
