I’ve switched, but this really is my one major gripe. Good to see others see it as a priority too, but if it’s been a conversation for 4 years then I’m not optimistic

Oddly, space is cold but spaceships tend to get too hot. Engines/electroncs/people give off heat inside the ship which gets trapped. You move heat by conduction, convection, or radiation, but because outside is a vacuum you cant disapate heat with the first 2 and are limited to the least effective radiation so the heat builds up
