  • Seriously. We are talking about tire tread compared to weight. Both use multiple sizes of tire depending on the year/model. There are a few that overlap in diameter to get the closest to comparison but they still have a very different width. We are talking about a 235/35R18 vs a 235/75R18. That is a huge difference in wall height/aspect ratio and changes how the tire gives under power. Those numbers massively change depending on model as well. Something like an f150 raptor could have a 315/70R17, almost a foot wide. So comparing just the weight and saying they are close enough is far from a fair comparison.


  • You are on a nuke loving platform and people are going to downvote anything that isn’t hard pro nuke. But you are correct. I have had this exact same discussion before. The numbers you are looking for are called the LCOE, or the ‘levelized cost of electricity’ where the lifetime of the technology cost if factored in. Offshore wind is currently the lowest followed by solar. Nuke is clost to 10x the cost. There is even an international nuke consortium that has several reports agreeing with exactly what you are saying and basically sum it up as: if you invested in nuke early, then it is cost efficient to just keep upgrading. If you didn’t invest in it early, then the cost to implement it so high that you are better off going wind/solar. Even if you add in the cost of battery systems, it is still cheaper than building a new nuke plant. And more than that, with these new nuke plants you have to upgrade all your infrastructure because your old wires can’t handle the output loads. If you look at the 30+ billion Georgia spent on this plant, they could have simply given out a micro generation grant to everyone to add solar to their roofs, not needed to upgrade the lines, and been far better off. But hey, just like reddit, if you are commenting on lemmy you better be pro nuke only and ignore the other numbers.



  • I agree with you as a realist on the situation. We will never stop manufacturing them, at least for the foreseeable future. But we forget that something like recycling is the last stage of the 3R’s to follow. We must first look to reduce consumption. We need to find alternatives where possible, and switch away from these forever chemicals anywhere we can. Next, while “reusing” is not the best term here, but we need to find ways to extend the life of the products that we are forced to use and try to use them up in every way we can. Then lastly we need to be recycling it as best as possible before we send it to an incinerator, or more realistically a developing nation landfill.

    Reduce -> Reuse -> Recycle is listed that way for a reason. Everyone always just jumps to the final stage then argue about how bad the recycling is while not even considering ways to reduce or reuse throughout the entire process.


  • 600$

    To employ someone at 10$/hr, their actual cost is probably close to 15$/hr when you factor I them coming in to work in the office and all the costs associated with that. At 15$/hr it takes 40 hrs to cost 600$ to thr company. That is one week of work for one employee. This means that they could have a 600$ fuck up every week and still break even over hiring a person. And we are talking about just one person. Chat support is nor.ally contracted out as entire teams and departments.





  • I can see that critical thinking isn’t your strong suit, but I’m willing to comment it out with you instead of just down voting.

    If the price of solar is already the lowest -and still dropping- then how is the most expensive option that takes about a decade to implement a better option for right now? This apparent point of diminishing returns is only beginning to manifest in even lower prices than this 2019 chart. And this diminishing returns point is only in the cost of the panels dropping; they are still getting better in technology and improving efficiency while maintaining low prices. If your argument is “solar can’t continue on this trend forever” -no one expects anything to consistently drop almost 90% every decade. Of course it will level out. And when it does, it will STILL be the cheapest option.


  • Huge up front costs.

    “On a levelized (i.e. lifetime) basis, nuclear power is an economic source of electricity generation, combining the advantages of security, reliability and very low greenhouse gas emissions. Existing plants function well with a high degree of predictability. The operating cost of these plants is lower than almost all fossil fuel competitors, with a very low risk of operating cost inflation. Plants are now expected to operate for 60 years and even longer in the future…”

    “World Nuclear Association published Nuclear Power Economics and Project Structuring in early 2017. The report notes that the economics of new nuclear plants are heavily influenced by their capital cost, which accounts for at least 60% of their LCOE. Interest charges and the construction period are important variables for determining the overall cost of capital. The escalation of nuclear capital costs in some countries, more apparent than real given the paucity of new reactor construction in OECD countries and the introduction of new designs, has peaked in the opinion of the International Energy Agency (IEA). In countries where continuous development programmes have been maintained, capital costs have been contained and, in the case of South Korea, even reduced. Over the last 15 years global median construction periods have fallen. Once a nuclear plant has been constructed, the production cost of electricity is low and predictably stable.”

    TLDR: If you weren’t already on the nuke train when it was going, the upfront costs are too much to make it worth it this late in the game. You are better off just getting solar/wind + battery. If you already invested in nuke, then you are good to keep updating them.
