    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.






  • Sounds about right. Most of the Japanese manufacturers have had to put a higher amount of effort on reliability, in large part due to Toyota’s amazingly strenuous testing of reliability before they even consider dropping a new product on the market. As a bit of a bonus to that, once reliability was upped, making more sporty cars could be achieved because you had the budget to change around the driving dynamics of a car without making it inherently unreliable. The Miata is probably the best example of this, as while each generations drivetrain usually isn’t too special (outside of being high revving), it manages to handle well and be reliable while doing so.





  • 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.


  • My father has had two heart attacks. The first was a pretty standard one by heart attack standards, required a stint to be put in and two days at the hospital. The cost was ~$40k and after insurance we were left with I think a $4-5k deductible (pretty good county employee insurance). His second one luckily (ha) happened while on the job and required another stint to be put in (he got amazingly lucky, as it was a widow maker of a heart attack) and was covered under his works insurance.

    For reference, I’m healthy and in my late 20s, I pay ~$250 a month through my employer’s health plan, $25 for an office visit, $500 to walk through the doors of the ER, with a $3k in network deductible ($6k out of network). Believe me when I say you are amazingly lucky to have the NHS.



  • I read your argument as being that since we aren’t quantum leaping ahead with technology, it’s a bit of a wash with the pushes for future battery standards. But my point is that this battery update, while not being a 10x in performance, is more likely a 2x and will be viable to scale with pricing decreases as time progresses. I’m in the trucking sector, and one of the things I have noticed about transitioning to electric heavy duties is that a lot of the issues aren’t completely on battery density, but rather that there isn’t an infrastructure that can charge the batteries at high voltage without beefing up the power grid around stations. If you could instead give a cheap enough battery backup to create a buffer that fills up during lower use hours, then a lot more of the solutions for that could charge ev trucks quickly would make more sense (it’s actually what has made the Tesla Semi have such good numbers). It’s stuff like this that actually might push the transition, which has to happen, not waiting for next quantum leap.


  • I mean, lithium cells were used for fringe use cases 20 years ago, now they are seemingly everywhere. The difference with this tech is that they know it’s currently expensive, so are aiming for use cases where the added cost is justifed. Give it 5 years and the tech will more than likely become easier to produce, lowering costs. That and sodium batteries are probably going to dramatically lower cost for grid storage, which should make it easier to have consistent power delivery.



  • It’s a stretch, but it is much more reasonable than simply monitoring all of the faces of users as to what they are doing while in their cars. Which is a strategy that is used by a lot of the newer tesla and other cars for autopilot and the like, in large part because auto manufacturers don’t want to be blamed for their customer’s stupidity. I can absolutely see that being effective, but very invasive into people’s privacy, and eventually something a politician pushes. At this point, enforcement really isn’t enough and the only way to truly fix it kinda is some passive limitations. I’m not saying complete lock down of functionality, but make there be some safeguard that only passengers can get away with for more than just changing music or receiving calls if the GPS is reading more than 20-30 mph.
