  • UK PEOPLE: this is REALLY IMPORTANT.

    @oschonrock @PeterSommerlad @cstross This gets at a particularly dumb part of “banning VPNs”: the VPN is just the transport mechanism the proxy service uses.

    No, we’re not a VPN, we’re a SOCKS proxy.

    No, SOCKS is banned now, so we shut that down. We do offer a QUIC proxy, though.

    And so on.

  • TL;DR Most EV batteries will last longer than the cars they’re in.

    @IronManIV @jwildeboer Unfortunately, a lot of the cost of a car is the frame and body, and techniques which have dramatically lowered the cost of entry have also dramatically increased the cost of repair. Unibody construction is simpler and cheaper (and lower-rattle, etc.) than body-on-chassis-on-frame, but if it bends in a collision, good luck straightening it out and restoring it to spec strength.

    @jpaskaruk @jwildeboer Early hybrids did have battery longevity problems. The first few Prius versions used a big, heavy NiMH pack which could store around 0.8 kWh (exact capacity differed over the models). It lasted around seven years before showing significant degradation in capacity, manifesting as steadily declining fuel economy.

    They switched to lithium batteries a while ago, and those are both lighter (and “Lightness makes you [more efficient] everywhere.”) and longer-lived.

    @npt_writes @jwildeboer It depends on the car. Most now reserve some capacity from the top for longevity reasons. That is, the vehicle only charges the pack to 90% of the pack’s nominal charge, and calls that 100%. This both helps the actual capacity to degrade slower and hides the degradation for a while.

    Plug-in hybrids also typically reserve about 10% of the capacity for KERS, which similarly keeps the charge above the minimum.

    @david_chisnall @jwildeboer With cars being so expensive to repair, EVs get totaled by insurance pretty readily. With the cells lasting so long, there’s very little demand for used EV batteries. As a result, they tend to be really cheap from junkyards.

    I was recently looking up how much a replacement battery pack for a particular hybrid costs. Turns out it’s about $1800 for an 11 kWh pack, but while looking I also found a local wrecker selling a 75 kWh pack from a Mustang Mach-E for about $3k.

  • Ten years ago, if someone had told me that tech policy bloggers would be calling for ICE to be abolished, I would have thought it very unlikely.
    ZimmieB Zimmie

    @evacide Abolish ICE is too wishy-washy. I would much prefer to see calls to *prosecute* ICE.
