  • People also dont get the differece between average and marginal. Adding consumption doesn’t build more wind farms. Adding extra electricity consumption means in short run burning more coal and gas. They are the ones that can be ramped up / ran more hours.

    In the long run they might build more nuclear, but that takes a (very) long time. Generally they’re building solar and wind pretty fast already, it is hard (costly) to ramp that up.

    Adding new sources of electricity consumption just keeps the fossil fuel power stations running for longer. Efficiiency is stuff like electric mass transit to replace as many car trips as possible - and using as much wires as possible instead of batteries. But no all the money will go into facilities and subsidy for battery powered cars.










  • bigclivedotcom has a few button videos covering elevator and industrial illuminated buttons. I don’t think he’s done exactly the same as this, but I think no real standard, but they may be cloned off a brand.

    Interesting videos to see what’s inside the different types. Some use a dual chip back to back parallell led - so that it can light on each half wave of a.c. - or if d.c that’d be either polarity. some have resistors, some have resistors and capacitive dropper (mains rated)

    I’d guess the reason for the voltage range is the different resistance included. I don’t think you’ll really know unless you either measure the current draw, or open it up.

    But if they do get jumbled, sorting them back out into different experiments, batches or subjects or time periods might make you prefer some extra info accesible by eye.

    If you’ve got a robot sorter maybe a qr code - but you’d have to be pretty large scale for that to be cheaper than a human.




  • I went to a university that thinks of itself as prestigious - though not a US one. The teaching and the course were a bucketful of shite. All it really had was decent libraries. There was the odd smart person, but they all did mostly research and were hardly involved in teaching.

    Admittedly, I chose a stupid subject that I now know to be useless, but the university shuld have known that and not offered the course in the first place. It was a massive waste of my time. Fortunately for me our Government covered most of the fees - but that just makes it a waste of other peoples money.

    The whole thing seemed largely to be a badging excercise for a bunch of posh cunts.
