1 day agoThink of the speeds you could fly at with no drag! I’m so bummed that the Grace Hopper drone didn’t get to fly after Intuitive Machines fluffed their second landing. That would have been awesome outreach from NASA.
We want drones on the moon!
Solar photovoltaic doesn’t involve steam. We can be solarpunk as well!
I guess hydro-power uses steam in the global water cycle so I’ll give you that. Radio-Thermal Generators are all solid state, but not much power on earth comes from them.
