Space is a tough place to be. People complain online about Texas weather swinging from hot to freezing in mere days or hours (and maybe even display weather that belongs in all four seasons within
a week), but just a couple hundred miles above the state, the swings are even more wild. Near the Earth, orbital space can be as cold as 100-150 degrees below zero in the shade, but up past the boiling point in sunlight.
So, yes, progress and invention continue, even for something as boring as heating, air conditioning, and cooling vital space systems. has developed the Flow Boiling and Condensation Experiment to enable two-phase fluid flow and heat transfer experiments in microgravity One of the biggest problems with future EV charging is the power involved. Everyone wants an EV that can charge up in five minutes, much like a gas-powered car. But, to do that will require that we send a lot of energy through a cable into the car. Put enough electricity through a wire, and it will start generating a lot of heat, unless you make the cable huge, thick, and heavy. That’s not going to work out well if we want people to be able to charge their own EVs.
