  • I believe paying taxes is a fair tradeoff for living in a society. My concerns are that those taxes be applied fairly, even if that impacts me, and that they be used to improve society for its people, even if it costs me more.

    I know people who are elderly or have lower income, I have kids in college, I have been between jobs in parts of my career, I’ve had major medical emergencies in my family …. And I have the empathy to want no one to go through that without assistance. I know the only way for people to “pick themselves up by their bootstraps” (I know, I know), is that when they fall off the tightrope they are caught before hitting the ground. I know the only way to break the cycle of poverty and crime is for kids to start with the same opportunities as their peers. I know that technology and science can be directed and accelerated by targeted investments. And yes, even if it costs me more. My successes are a product of my society and it is fair for them to feed back into society



  • While I don’t want to fanboi too much …… as long as nobody is able to do self driving, any approach has potential. Teslas approach has the huge advantage of starting with millions of potential vehicles and they will soon be able to crank out a quarter million robotaxis every year, whereas Waymo is not ready to scale up. They’re going all in with a potential approach and if it succeeds are in position to disrupt the industry.

    It might not succeed, but no other company has succeeded yet either. The difference is they went all in, and they were willing to try something different than Internet wisdom

    (Actually, as a big fan of what Tesla used to represent, this worries me about their future: Cybertruck flopped, robotaxi may not succeed for years, semi is a very conservative market they may not be able to break into or will be slow take up , and Optimus doesn’t yet have a market. They’re making some extremely risky moves at the same time their profit margins are under a lot of pressure. )





  • As a European those power draws listed sound absolutely absurd to me

    Let me clarify - those are standard sized circuits, not actual draw. However the service has to be sized to handle it, and over-provisioning to account for it.a customer might install a stove that draws the full load and might use all the burners at once, and you have to account for typical usage patterns.

    For sure it’s a well earned stereotype that Americans use more electricity than many other places. We tend to have bigger houses, more and bigger appliances. We not only don’t have that base charge per size of service but too some extent are charged less to use more: essentially we subsidize people electric resistive heat, who can pay a lower usage rate. We also don’t usually have time of use metering, although some do: my rate is the same whether I charge my car at night or at peak time. And of course our current leadership is intent on rolling back the efficiency standards we have.

    Taking your heat pump dryer example, those are finally available here but tend to cost a lot more than a traditional dryer: savings on efficiency will never make back the extra purchase cost More importantly they’ve only been available in small sizes, not typical for houses, especially with families



    1. Sometimes breakers don’t trip, so there’s a small risk of fire
    2. Restarting the whole house may have large initial loads as everything starts at once: more chance of it happening again or potentially damaging some appliances
    3. Risk of heat damage to wiring with repeated trips, risk of broken connections from more frequent expansion from heat/cool cycles
    4. Inconvenience, especially in the old days when you’d have to go through to set clocks. If while asleep you might not be awoken in time. If you weren’t home, maybe food gone bad
    5. Occasional home health appliances are critical to keep going

    Realistically it comes down to how conservative you are with over-provisioning. You might also expect it to handle the load for 50 years of growing usage. In the US we have the expectation of rarely to never tripping the main and when that happens it’s more likely an electrician call



  • In my experience people get by with a 3x25A (17 kW available, matches approximately a 70A service in the US)

    Wow, how do you do that?

    Of course over-provisioning is a thing but that’s crazy. Maybe you have much smaller appliances or assume much lower usage, but 70a basically assumes 2 major appliances at a time, using close to max load, and with nothing else turned on.

    Typical 240v major appliances

    • level 2 EV charger: 50a
    • stove: 50a
    • central ac: 40a
    • dryer: 40a
    • heat pump: 50a+
    • water heater: 50a

    Of course you won’t use them all at once and they won’t usually be drawing their full rated load but I would not want to deal with being limited to one at a time so I can also turn on the lights or use the microwave

    That can theoretically draw 280a, before you even count things like lights and small appliances. If you added up all possible circuits, you may be hitting 1000a theoretical in a modern house. I’m comfortable that My 200a service will handle any combination I might use, but 70a definitely not

    By contrast I once lived in an apartment with 60a service. It did not have most of these large appliances but I frequently tripped the main with combinations like stove + window ac + microwave + lights



  • For me the smart charger was a key feature, and I never understood why that is never talked about. I have 200a service which was plenty for one fully powered charging service, but with the likelihood of electrification in upcoming years I was hesitant to have two. It was pretty clear I needed to prioritize smart charging so I’d have that possibility.

    I can also configure it to only charge my allowed vehicles, should that ever become an issue

    So far my family only has the one EV, so we only need the one charger. But I like that if we needed a second charger it could be on the same circuit and they could dynamically share the power to maximize charging





  • Counterintuitively, ms phones good reviews were also a good reason for ms to kill it. By the time ms got moving with phones, they were way behind and the market was already consolidating. They had a lot of inertia to overcome. They dumped tons of money into phones, exercised the famous ms marketing arm twisted, pulled out all of their usual tricks … and no one bought them. They ended up with phones that people liked, that got excellent reviews … and no one bought them. Even worse, phones were being sold on the strength of their app stores, and despite sinking tons more money persuading developers to port apps to windows phones, they could never get the critical mass of a sustaining ecosystem. It was pretty clear that even ms would not be able to overcome the consolidation of the market into only two
