  • The problem is it’s not really people’s choice. Companies have gotten very good at disguising quality tradoffs and marketing has got very good at muddying the waters.

    Since this is about tools, I’ll bring up Craftsman as an example. For many years, it was a quality brand accessible to homeowners. But as they changed to be cheaper they still marketed themselves as a quality brand and they seemed like the same price. It was only after the brand value was destroyed, that it became clear how “cheap” the tools had become and people were able to make a legitimate decision to move on






  • The problem is it’s very expensive. Solar installers charge tens of thousands of dollars and has a long history of scams. They take the place of the old trope about scammy used car salesmen. They’ve created leases and PPAs in an attempt to make the initial cost easier but only succeeded in being scammy

    It doesn’t help that we have tariffs and other barriers to low cost solar panel imports, yet insufficient support for domestic manufacturing to be competitive.

    The math is hard. Everyone wants to know the payback threshold from the huge install cost up front but it’s not straightforward.

    When I looked into solar I found

    • lots of scammers, poor service
    • I calculated a payback of 12 years from install cost given free energy, which is longer than I’m likely to own this house. But they claim 7?
    • I only have sufficient unshaded roof for half my usage
    • is it poor service or scamminess that it’s so difficult to get them to explain that?

  • A big part of it is being realistic about how often that would come up.

    Especially for those with their own house, charging overnight at home (like you do with your phone) is more convenient. It is so nice never having to go to a local gas station!

    Forget looking for discounts like Costco, charging from home is half (for me) the cost of gasoline. Everyone likes saving money

    The only time this doesn’t work is road trips, where I need to stop for 20 minutes every 4-5 hours of driving. If I’m eating a meal, it’s going to take longer than that anyway.

    So

    • 90+% of the time an EV is more convenient and much cheaper
    • on road trips where I would have stopped to eat, it’s equally convenient
    • on road trips where I’m stopping more than I would otherwise and for slightly longer ……. That’s actually very rare

    Edit: looking at my charging stats, it’s only been twice in the last year. One of those was a 1,200 mile road trip that did wonders to overcome my range anxiety


  • most Americans don’t want an EV with batteries at their current state.

    That’s a risky assumption given how driven by propaganda this is. The reality is current state of batteries is perfectly fine for most Americans. What if they realize that? It does partly depend on charger availability, which is being rapidly built out despite the efforts of the current administration to block that. What happens as Americans realize how many new chargers are near them?

    Plus methane is a much stronger greenhouse gas than CO2, even with the shorter lifetime. We seem entirely unable to reduce methane leaks or even measure them against natural gas usage.

    But from a consumer perspective.

    • where I live, electricity is much more expensive than natural gas, maybe double the cost per unit of energy
    • and I pay even more for 75% renewables
    • I just got a heat pump installed for my addition. So far temps have gotten just a bit under freezing and it has no problems keeping up

    But that adds up to a reality where the cost threshold is mid-40°F’s. While it may be an argument in favor of solar, I don’t have enough unshaded roof to generate more than half my usage


  • Signing (intermediate) certs have been compromised before. That means a bad actor can issue fake certs that are validated up to your root ca certs

    While you can invalidate that signing cert, without useful and ubiquitous revocation lists, there’s nothing you can do to propagate that.

    A compromised signing certs, effectively means invalidating the ca cert, to limit the damage
