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

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.
