> The telescope consumes 250 kilowatts of power A better investment than bitcoin, IMHO.

I completely agree. I think it makes sense when they have 256 processing nodes with GPUs plus everything else, just the number caught me off guard at first.

  I work on a plasma confinement device that has a linear regulator in its 100 kV gyrotron power supply that uses 6 kW just to keep the filament warm. The coils use 10 MW during a shot. And this is considered a small machine. Science takes power.

      And, just like that, donating your body to science has new meaning.

        Either that or a zombie apocalypse.

      Well the pay is about half the market rate and I'm leaving soon because my SO's research group is moving across the country. I suppose I'll just go work for industry and be able to pay off student loans/own a house in my life. Science could hold on to talent if only there was a budget for it.

    Neat! How long does it take to charge capacitors before a shot? Or do you have a transmission feeder directly into your lab?

      We use 18 DC train motors with 1-ton flywheels on them. Currently they spin up to 1650 RPM then get turned into generators. It takes about a second to spin up the very inductive copper coils to the desired current then the shot lasts 100 ms. After the shot the motors are spinning at 1200 RPM and it takes 5 minutes to get back up to 1650 RPM.

You can’t even make the Bitcoin transaction that investment would require for that pathetic energy usage.

  As if "bitcoin investors" actually make transactions! If they did, it would matter that the network isn't functional

Bitcoin's efficiency is not relevant to the discussion. Every other comment about energy consumption pulls replies with complaints about Bitcoin mining. It brings nothing new, it distracts from the topic, generally lowers the quality of the discussion. Don't do it. If you must vent, do it where it's on topic.

Why start this discussion. It's slightly expediting the heat death of the universe for no reason. Are you trying to eliminate all order in the universe???

A silly argument. Electricity isn’t finite and we can essentially generate as much as is demanded.
