    Dang, you weren’t kidding with the price of a used x220 (I have an x230 that I got for less than I’m currently seeing on ebay a while back, and the only thing that really made me switch to something newer was the screen). Maybe a newer thinkpad or an hp elitebook? I think as long as you have something newer than a 2nd Gen I series chip, there really shouldn’t be an issue if you’re basically just using it for text processing. If you start with models with ddr3 and sata drives you should be able to get very cheap replacement parts for a while yet.






  • But then you’re just having another system for storing energy, which probably isn’t very easy to implement. An easier solution if you don’t want to use grid batteries is just to improve housing insulation and schedule heating/cooling for non peak hours, so that you are just using less energy overall. The problem in my mind is that that would require a lot of renovation on older homes, which is just more expensive and slower than adding grid batteries. Don’t get me wrong, those changes should be mandated for newer housing, but expecting it to be implemented in older housing probably isn’t gonna happen.


  • There are plenty of alternatives for lithium batteries, chiefly sodium and a redox flow. Heating/cooling is good as well to store, but not every structure is energy efficient enough that it would make much sense. Good thing to work towards, but grid batteries would probably be faster and easier to implement. I have reservations towards pumped hydropower, in part due to watching how hard it is to decommission a lot of hydroelectric dams these days in US as well as the cost to create the areas to hold the water (a lot of the areas that are geographically advantageous for pumped hydropower tend to be nature reserves or national parks, soo…).





  • But the price increase kinda is a symptom of the underlying issue. For reference, the reason that subway subs were $5 for a long time was that the company was trying an advertising campaign to grow the brand, which it did amazingly well (honestly, far too well). However, those were not sold at a sustainable price, but whenever the company tried to raise the price it was perceived very poorly by the market. So they kept the price low for a long time, and eventually had to raise it but due to inflation (and decreasing the sub size to compensate for the low price before that), but the price increase was pretty drastic to most of the customers who often stopped going there.

    In other words, the company kept the price down artificially to keep their stock price high, and foisted a lot of the actual costs onto the franchisees, of which they had tons. Which is obviously not a sustainable business model, and it’s why less people go to subway anymore.
