    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…).



  • 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.




  • Oh, I don’t doubt it’s possible, but getting the avg person there is the issue. At my milage, if I really absolutely wanted to go electric, an ebike would frankly be a better option (admittedly, much harder to haul stuff, much less safe, and annoying during the summer which is very hot in my area) for low range stuff. Phev Hybrids are a decent option, but again, if you don’t have a place to charge at night a lot of the benefits are neglected. Not gonna lie, I do actually suspect that that will change in the next 10 years, as tesla have finally hit critical mass I my area, and they are much cheaper to fuel, something that isn’t highlighted enough in my opinion. And I suspect that sodium batteries will more than likely cause it. Having something incredibly cheap to drive is more than likely what will turn the tide of evs, and it is why I am very annoyed that Chinese evs aren’t being imported into the US without insane tarriffs. Once cheap evs are common, the need for charging might actually get some real notice. That being said, I think my considerations aren’t very far off from the concerns of many buying cars right now, and at the current moment those without a range of at least 200 miles are a much harder sell (and why lower range vehicles don’t seem to sell on the used market).


  • I live about 5 miles from work. I usually drive about 20 miles a day, so about 140 a week. I also rent an apt where there are no options for a charger. I considered a mini Cooper se and even a fiat 500e for a bit (it’s really cheap when you can find it), but once I looked my driving, I was only going to be comfortable with a 200 mile range for the occasional (once or twice a month) trips that are 100 miles one way. While chargers along the trip might be available, most times I’ve seen them they are clearly broken (provided it isn’t tesla, which seems to repair them). I do live in a city, but even then the 100 miles range would be tough to accommodate. Not saying impossible (I’ve seen electric mustangs and electric Chevrolets in my apartment), but a range of 100 miles is a lot less feasible for most than I think the data suggests, although that might also be fine if charging was faster.




  • Not really. I compared it to an older Chevy s10 for a reason. Those were relatively small trucks that, while not always the most reliable, are still a pretty decent option for most people. Kei trucks are a smidge smaller, but are better on gas and frankly less safe. I don’t think this is a “get rid of bigger vehicles and this goes away” but of a “Kei trucks aren’t really any safer than an off-road golf cart and current regulations allows them on the road”. We need the safety regulations so less people die on Auto accidents, and kei trucks don’t really have to comply with even the basic ones.


  • They’re not really safe. They are generally front heavy, so there is a risk of rolling forward, no crumple zone safety stuff, more often than not the front suspension is under the seat and if that breaks it would shoot up into the cabin, and on top of everything they are pretty slow. They have more in common with an off road Polaris than a traditional truck, which is to be expected because they were mostly designed to be farm trucks. I’d much rather be in an older s10 than a kei truck in the event of a crash (and s10’s aren’t very safe). I think I lot of why they are so popular these days is because there aren’t really any light trucks anymore, and these are an alternative.


  • Raspberry pi foundation was launched as a charity, and the end goal was to produce a ton of very cheap computers to help children learn about programming. Since then, it has been soo ubiquitous for embedded stuff that for the last couple of years they have basically become unaffordable for the very audience they were intended for. Now they are seeking an ipo because they are used in everything, except as cheap computers for children.
