    I’m glad somebody is doing something useful while the dying American empire flounders around doing genocides.

          The big problem with space is overheating. Space may be cold but there is no way to get rid of that heat except for radiators. Convection doesn’t exist in a vacuum.

        Not really. Current battery technology is to put it lightly not the type of thing you want to rely on for long term life support. Lithium ion the current go to for rechargeable batteries physically degrades as you charge it. One of the main things you can do to reduce this is don’t fully charge the battery. For example if the battery degradation from 0%* to 100%** is a cycle then 50% to 80% is only 21% of a cycle. That’ll extend the lifetime of the battery (not the capacity) by about 5 times! That’s pretty significant but you lose out on 20% of the batteries capacity permanently, even as the capacity decreases from degradation.

        You’ve probably seen the hype about Sodium batteries which are currently 50% less energy dense which just immediately means NOPE for use in space.

        * Lithium ion batteries are extremely difficult to actually fully discharge (controller won’t let you)

        **Lithium ion batteries should never be fully charged it causes them excessive damage so the controller prevents this from happening
