If these are supposed to be used as backup generators then gas turbines are a good fit in technical sense. Can start quickly, don't need a lot of space or cooling, can work on partial load; lead times are somehow short, and you can just pack it all in containers and set up anywhere which seems to be important. The catch is that efficiency is probably just below 40% instead of 60% and slightly above for regular CCGT plant, thst is you need to burn extra 50%-ish gas (methane is cheapest fuel and can just be piped). about anything that burns and can be pumped through a nozzle can be used

Then there's matter of smog. You're supposed to put giant catalytic converter (sorta) on this thing and normal powerplants do just that. Apparently techbro oligarchs decided it's not disruptive enough this way

but dw this won't last, talking about bubble broke to the mainstream now

don't let crackheads know about it

it's a flow battery, so it keeps charge basically indefinitely (when not in use energy-bearing parts are separated). you can run it as hard as you need and it will not degrade in use-dependent way, at least not as hard as lead or lithium batteries

to elaborate on durability, there's no capacity loss with these batteries. so if design intention is to run these batteries from full to empty and back every day, and maybe a bit more* they can handle it no problem, because everything that happens, happens in liquid phase that can't degrade. lithium battery will degrade fast with such usage, but this one won't. on balance, there's need for pump and electrolyser maintenance, but at least you won't need to rip apart everything and replace all batteries every 3 years. per kwh per year of use it might be cheaper this way

* they might want this battery to provide energy in the morning, before solar panels kick in, soak up excess energy from noon peak, then discharge it in the evening. that might be 500ish cycles per year, and they can run it at full tilt

it might be that one of your drug-metabolizing enzymes doesn't work properly, tell your doc, there are tests for that

i like the 2y+ lead time

will pencil keep it wide open enough? the intention was to keep it slightly open, then put it in a bag and go around. years back when i had a laptop that shut down wifi with lid closed i solved that by taping a packet of instant ramen to palmrest for one evening

macos users have budget for these objects

depending on your build, putting an extra switch disconnecting lid switch could be a better idea because power management is hell on linux

because it's targeted at tools, too

and also, it would break the hinges in intended use, and as pictured it can't work (doesn't hold the lower half). pair of wedge shaped things would work much better, i think

keyboard is wrong way for the same reason
