  1. In Michigan, my overnight electrical rate is $0.13 / kWh. For my car, that is about $1.07 to go 30 miles.

    Starship

    I wondered a bit about that too, so I looked it up, here is one explanation: "Sidestepping decades of precedent, Musk says that Starship will have no separation mechanism at all. Instead, at some point during the design or testing process, Musk decided that a separation mechanism was entirely superfluous and that the same effect could be more or less replicated by using existing systems on Super Heavy. By using the booster’s gimballing Raptor engines to impart a small but significant rotation on the rocket moments before separation, Super Heavy could effectively flick Starship away from it – a bit like how SpaceX currently deploys Starlink satellites from Falcon by spinning the upper stage end over end and letting the spacecraft just float away thanks to centripetal forces. Because Starship is something like five times heavier than Super Heavy at stage separation, the ship would effectively float away from the booster in a straight and stable line, use cold gas thrusters to settle its propellant, and ignite its six Raptor engines to head to orbit. In return for the slightly unorthodox deployment profile, if this new approach works, SpaceX can entirely preclude the development of a pusher/spring system capable of pushing a ~1300 ton Starship away from Super Heavy. That approach is possible on Starship in large part because the ship’s six Raptor engines are completely tucked away inside a skirt, meaning that there is zero chance of nozzles being damaged by impacting the booster interstage."

    Starship

    a pic from twitter showing the pad damage (with the original forms for the concrete pour on left). Elon says they were planning a flame diverter / water deluge but it wasn't ready in time so they rolled the dice and went anyway. I wonder if his desire to launch on 4/20 overrode some people who wanted to wait, but OTOH they have another rocket soon ready to go so just saying "lets get this one gone and we can keep iterating" has a point. Elon claims next launch in 2 months, the armchair QBs on NSF say 4-6 months.

    Starship

    barely. I saw NSF has video of one of their remotes with a car parked by the camera. A big chunk of concrete smashes into the car, maybe totaling it depending on if there is frame damage. As Phil said, those seconds on the pad with the engines running was not good for it. Maybe knocked out a few engines or caused some other damage to the rocket itself...
  5. A personal anecdote illustrating that this whole e-car ship has sailed and Brent has to let that shit go: My next door neighbor, who flew a Trump 2020 flag, then a Trump 2024 flag, then a Lets Go Brandon flag, and who vowed during the George Floyd protests that his personal arsenal would be ready to protect our neighborhood...just bought a Tesla Model S. It's over.
  6. It may be worth pointing out when it comes to electricity usage that not all crypto is equal anymore. Ethereum switched last fall to a proof-of-stake model from a proof-of-work model, which cut its electricity requirements by 99%. So when people say "crypto miners are sucking electricity" they mean just bitcoin.
  7. this post ended up sending me down a 2+ hour rabbit hole of answering the questions "what is a carbon cub" and "what would I do with one" I learned that you can buy one new for 300k, or build from a kit for about half that. They climb quick and fly slow. I wondered what the point would be unless you lived in Alaska or Canada though.
  8. They basically pushed the $250k of automatic depositor insurance up to "unlimited", because the risk of many smaller banks going under in this difficult situation, and they are going to use the same bank-funded insurance fund to cover the shortfall. I can see their point, with the rise in interest rates banks are having a lot of trouble so this is a problem not entirely of their own making.
  9. magic (that vid was so fun. I didn't remember then starring in it)
  10. SC has survivor bias. The people who can put with the constant snarkiness and sniping are those who like engaging in snarkiness and sniping. (like any good rule there are exceptions, Wendy and Joe are largely snark free)
  11. Degree (the joke we told ourselves back in the day, that some women were only attending college to find a husband. "They got married. He got a BS degree; she got a Mrs degree")
