A massive nuclear fusion experiment just hit a major milestone, potentially putting us a little closer to a future of limitless clean energy.

Imagine using HVDC to distribute energy farther at much lower loss. An upgrade to HVDC would net us about 40% more energy capacity without having to build a single new plant.
Grid-scale storage is being worked on in clever, interesting ways. For example, there are interesting mechanical storage ideas like ARES, using concrete laden train cars to electrically convert kinetic into potential energy, and vice versa.
A hillside, some rails, chains, a motor and some rail cars. All proven tech that we currently depend on for moving goods at low cost of ownership and high reliability.
There are many other clever options. Expand imagination and we can live without long-lived radioactivity.
Sorry to tell you your fist point has been known for over 100 years and is how we have been electrifying the planet. Good thing you're catching up though!
Second point… Same thing countries have been doing this with water for decades, now were "discovering worse ways" to do the same thing
Ontario Canada has been making 80% of our electricity from our nuclear plants for the past 50 years with 0 deaths and less contamination from radiation and other particulate matter than burning shit to produce electricity. And on top of that we had nuclear plants for making medical isotopes used in all kinds of medical procedures which can not be made any other ways.
Thorium reactors only put out trans uranics that only last 300 years rather than 15,000 and can also desalinate water or capture CO2 from the atmosphere?
Oh and it can use the waste from other nuclear plants that last for 15,000 years to produce electricity and make them degrade in 300 years.
We can make all those type of transport better with clean electricity made in a Molten Salt Reactor
Sure I'll Open my mind to better ways to make electricty, this includes nuclear
Here learn something
You know, tiny, it's funny how obvious it is that you've decided to actually look up the talking points to parrot now that I've actually challanged your low quality arguments. Would you like a cracker?
I don't generally learn what I need to know from sales brochures, as engineers are hired to find and resolve issues using the truth, dictated by physics and experience in machine shops. Additionally, there are a number of circumstantial issues that fog the translation between theory & reality. Keep up with me, tiny:
https://www.machiningdoctor.com/mds/?matId=5180 shows what we refer to as machinability, a reference number influenced by both crystal structure, and hardness. The low m/min value shows that it takes a lot of time (which is expensive) to machine a final product, be it a pipe, a valve, valve seat, or the particularly expensive heat exchangers.
Let's continue. What do people like drinking? Fresh water? Hey, you know where we ought to use the limited water supply? In a gigawatt energy storage system! Location needs to be right next to a river, which happens to be right next to a high mesa physically capable of withstanding several million gallons of weight (remember, 8.2lbs/gal of water, tiny). That tremendously limits location. How about problems related to flora and fauna, or the inability to scale the storage plants, or the issues of permeability of the ground, etc? Op-ex on gravity storage systems is almost as low as it gets, and a mechanical system further resolves most pain points, though admittedly adds a few small ones too. Still with me? Stop eating your crayons and pay attention!
Your medical isotopes only come from candu units, which are in limited supply for reasons which are fairly obvious to even tiny intelligences like yours. Very good, we've got Canucks doing a careful job with their reactors, though as with any plant, there have been mishaps and questions at other places. Indian point nuclear generating station, 20 miles north of NYC had a serious problem of unknown amounts of tritium leaking into the local water table, as well as the Hudson. The real problem was that after a decade of perimeter detectors going off constantly, nobody at entergy knew what the primary source was! I have direct experience dealing with this. As a single example,[ here's one of the times it happened.(https://www.nrc.gov/info-finder/reactors/ip/ip-groundwater-leakage.html). And this has kept happening over the years, to what in the industry was referred to as a model plant.
You need to understand that something can be high risk, low likelihood, and that's still enough of a deterrent to enactment. You're talking about a system which mixes extremely corrosive elements with high-gamma U232, making for a doubly-difficult to manage system. There are upsides vs b/pwr plants but both myself and professional industry agree that the upsides don't outweigh the very serious downsides.
I'll clarify that I am ok-nuclear, but only if nothing else works. Got it, tiny?
And you think current reactor designs aren't hard? Seriously? Wow OK end if story for you.
Thankfully casting this stuff is fairly easy. Has this stuff been tested in a SLS printer which would make your machining is hard point absolutely moot?
Tell me you have 0 clue about MSR by telling me they use water. Hilarious man. Try a CO2 heat exchange for the 500c temps the reactor runs at. The only water needed for a MSR is the secondary heat exchange between CO2 and water using a closed loop system.
Find any information bad on the much safer CANDU reactors, MSR are magnitudes of order safer due to not having 900+ psi water acting as a coolant
The limited supply of CANDU is just due to stupid politics/bureaucracy, Ontario has been trying to build a new reactor for the past decade and was nearly canceled under our moronic Liberal leadership at one point
Once again the guy who literally invented both types of reactors favored the MSR design. I'll take his opinion over yours as he actually worked with the shit leadingntonthe creation of Hastaloy N. Not C233 or w/e you linked.
We have the technology to deal with every problem you have with the MSR.
If gamma ray make it so hard to do anything why did we created cobalt-60?
And to put a cherry on top
Again this works on small scale but does not fit power a large scale modern city and does not scale with our energy consumption needs over time. HVDC Is great when it's a state away or less but what happens when it's 2? 3? Four states away? There is still energy loss. Nuclear is long term, energy independence that scales with our energy needs. Nuclear does have long term radioactive but if processed correctly is not really a burden. Untimely it will be a combination of all these techniques that save us but what I'm saying is that for base load power. Nothing right now beat nuclear in terms of convenience, raw power output, energy independence, and reliability. Modern reactors are safe, advanced, and capable of generating more energy than we even consume.
Nuclear power as we know it might be ok but for that reprocessing issue. The Brits finally had enough of a need that they pushed legislation permitting movement of nuclear waste for the express purpose of reprocessing into useable fuel. They have quality trackage, thorough testing of storage cars, and most importantly a well-heeled rail management office, with a lot of power to ensure the rail operators follow the rules, and Dave real consequences when the rules are broken.
Meanwhile, we've had that recent large derailment of toxic chemicals in Ohio that I'm sure we'll be in people's memory for a while, particularly when we start discussing carting spent fuel around. Currently poor infrastructure in the US? ✔️ Low-value penalties sure to a corrupted political system? ✔️
Look, part of this is more than a technical problem, it's also a risk management and social contract problem. What do we do about a poorly regulated national rail system? How do we reassure people whose property may be seriously damaged by a potential spill that they'll be made fully whole again? This applies anywhere we're doing this, not solely the US.
Things are changing for HVDC, it can in fact be used for national-level distribution backbones with much lower cumulative loss vs an equivalent AC system.
Currently there's a $10 million grant to figure out how to make IGBT-based VSCs cost less, and based on that alone, it sounds like the US is looking at making that exact backbone, running east to west, with branches running north to south. Local distribution would take advantage of existing AC infrastructure, segmented into smaller subsystems.
