  • So I used to work in industrial automation, and I did see a factory owner buy a robot to automate a task because it was a brain meltingly simple task that was unpopular with his workers. The robot was slower, and more expensive than a human.

    It was taking a small piece of metal from a stack and putting it in a machine and pushing a button (not sure if he had a two-hand-no-tie-down set up) then taking the now bent piece of metal out of the machine and putting it on a stack. I think they had about 8 hours production per week of demand for the part.

    He didn’t do it out of the kindness of his heart but because he got tired of paying recruiters to find people willing to do it.






  • Abstract from Science:

    Storing sunlight in a compact and rechargeable form remains a central challenge for solar energy utilization. Molecular solar thermal (MOST) energy storage systems, which harness photon energy and release it as heat on demand, provide a direct approach, but have long failed to meet practical benchmarks. Inspired by the architecture of DNA, we report a pyrimidone-based MOST system that stores energy in the strained Dewar photoisomer upon excitation at 300 nm. Designed with sustainability in mind, the system operates solvent-free and remains compatible with aqueous environments while overcoming one of the field’s greatest hurdles: the controlled extraction and transfer of stored heat. When catalyzed by acid, the Dewar isomer releases enough heat to boil water (~0.5 mL). These advances help point the way toward decentralized solar heat storage and off-grid energy solutions.


  • I have neighbours homeschooling their kids, that ate similarly aged to mine. Sometimes we see them at the school playground on the weekend. The kids seem fine, the parents seem normal. They mentioned they take the kids to a weekly home school kids play date, and there is some sort of education resource worker that makes sure the kids are learning what they need to.
