  • Just try find and track the price per kg of a good, and you are in deep shit. Its some times hidden, after several “get the app”, “two for one” just to find out the good is fucking more expensive if you refuse go though the privacy invasing hoops. What the fuck happended to “Limited time offer until this actually cheap batch is sold out!”

    Sure it’s terrifying, but you can start a sparky plasma show in a resilient enough container and keep it going for hours and the microwave won’t break. (except maybe overheat.) The microwave will be fine as long as the arcs don’t reach the waveguide cover. (which would risk burning/shorting the magnetron.)

    I have done the microwave grape plasma trick myself and started an arc in a microwave. The current between the two objects goes through a very narrow point, which is enough vaporize the contact point to plasma. This then can grow as the microwave continues to pump more energy into the spark.






  • I’ll just comment about one thing that keeps popping up in the discussions: grid-level storage. There is no such thing yet really that would last a full day cycle, and the 100MW or so units we are building are mostly for frequency stabilization and for buying enough time to turn on a base-load plant when the renewables drop out. I’m not arguing against storage - it is absolutely needed.

    The problem is the scale, which people don’t seem to get. Largest amount of energy we can currently repeatedly store and release is with pumped hydro, and the locations where this is possible are few and far between. Once the batteries reach this level-of-capacity, then we have a possibility to use them as grid-level storage that lasts a few days instead of hours.


  • MSRs have negative temperature reactivity coefficient and outlet temps around 700C at atm pressure. PWR is at measly 300C and 150 Bar.

    If all control is lost, the salt expands as it heats up pushing the expanded volume out from the reactor core. The fission stops once the fuel is leaves the core region where the moderator is. Reverse is also true: you pull heat off from the loop, so the fuel-salt becomes denser, increasing reactivity. MSRs can naturally “follow” the load, if done right.
