  • Also, burying doesn’t work in all geography, despite assumptions from some know it all folks.

    I grew up in a filled in wetland with buried lines. Between occasionally having outages due to water affecting the grid, and lines that like to resurface as soils sink and flow, it wasn’t ideal and probably explains some Florida grid choices.

    Then I lived in the mountains and in dense forest. Good luck luck burying lines in rugged mountains full of granite and ravine.

    And heavy forest is also an issue. You gonna go around all the trees? Cut them down?

    Grid reliability and line safety is a serious issue. We lose people and towns (see - Paradise fire) when it isn’t right. But the obvious solution in your corner of the world doesn’t work everywhere. Redundant connections, infrastructure maintenance, local supply all matter to many.

    And yes, good reliable backup options, including the massive investment in the driveway, can and do certainly help. As an EV driver who has lived through many days of blackout, I can say that at first, the EV is super helpful. Warm up, charge the phone battery, even run an extension cord in for smaller loads. But this won’t last long. After a day or two, charging the EV is its own problem.

    I also have a (small affordable) backup generator! And I know how to use it for critical loads (fridge, wifi / comms, light, chargers). When I was in more vulnerable places, I had a backup backup generator which allowed small engine work on the primary during blackouts, and with both firing meant I could trickle charge the car during day and use the battery for silent backup overnight.



  • I work on this stuff. Pretty interesting situation with Chinese competition.

    Western culture has both normalized a safety first culture and sensationalized all flying accidents. FAA was built to uphold these things. The barriers to entry are so high, that effectively zero new companies or innovative products were successful for 50 years. Today tech companies are leaning in to lead the new markets, but it takes billions to get through the barriers, and most find it better to launch in less regulated markets. Zipline from CA, for example, has been flying medical drone delivery in Africa for many years.

    Chinese leadership decide what priorities are, and are willing to tolerate some failure and loss. They bring products to market quicker internally, the products are less mature. This gives them the opportunity to iterate in the field, which is a competitive advantage. But with lower barriers to entry may come inferior products, and time will tell whether those orgs iterate to succeed faster than Western companies aiming for high initial capabilities, or if the Western companies have enough war chests to carry them to market with superior products or if they burn up trying.

    At the moment, my career hinges on the Western approach, but I very much appreciate every step to minimize barriers.

    And don’t worry so much, honestly. These things will be comparatively safe before they drop off your order or pick up your kids, no riskier than the ride in today. Unless you are an early adopter is a less regulated market, then keep your head up.




  • So I imagine myself at the future factory in karma heaven trying to decide what I get to be and when.

    Humans are interesting, they experience much over a short time, and deeply. Early humans have a visceral and satisfying life, hunting gathering and reproducing. Late humans, which is most of them, have safe stable lives with infinite opportunities around infinite stars.

    Middle humans struggle. They multiply and have disease. They reach resource limits and have war. They are a brutal combination of technology and animal tendency which wipes out other humans and predators.

    And their triumphs are glorious. From steam to electricity to transistors to space flight in a few generations. They take poetry and teach machines to sing. They make their universe larger by finding how much space is between atoms. They smash the atoms and fuse them together again on the way to their future.

    I make my choice. Right there. Right at the middle of the change point. That’s when, that’s where.

    Hello friends. Im here for the positive change. Im struggling, its what we do. Enjoy

    But, it doesn’t change much, really. Folks need to move on from charge rate fetish or go deeper.

    My >5 year old Tesla does 250kW, this says 1000kW But - you dont actually charge 4x faster at 1 MW. Nor do you want to. 250kW doesn’t charge 2.5 faster than 100kW either, in my experience. This is because this is the limit, not the average. And the averages are slower for many reasons. Including you dont want to slam energy into your very expensive battery that much faster than you take it out, it will wear it out.

    And you know what? 100kW is good enough to charge over a meal or store visit. Packs are usually less than 100 kWh, and sessions are <<100%. And plugging in longer at level 2 / 11kW is better for the battery and grid if you’re in no hurry.
