Semi-related to this (the power density bit). There was a design for small arms ammunition in the '90s that used an electrical heating element. The propellant was water flashed into superheated steam. I don't know what the momentum impulse energy would be for superheated steam, but the escaping vapor would at least be supersonic, making it an interesting idea for a renewable propellant.

Just find a source for more water (clouds) than you are using and you could stay up indefinitely. Heh, an "atmospheric bussard ramjet". OK probably not.

BTW, the ammo melted and expended its aluminum heating element to get the effect. So you'd need something that heated up to those temperatures without expending itself per pulse,like a ceramic casing around a molten core. I guess.

PS a quick search revealed the inventor to be Rusi Taleyarkhan (of Bubblegate infamy). Lol

Hey, I did my part to meme-ify 131.

But apparently, my sentiments were in the minority. Hell only 25 people have even voted on the entry so I guess it's not really a part of most people's concerns one way or the other.

Though it didn't catch on, I glad there's at least a wikipedia page about it.

To add to what Fuzzy said,

There have been a number of nonstandard "ATX" cases that mount the motherboard upside-down on the opposite side of the enclosure mostly intended for multi videocard gaming machines. some of those even isolate component areas like BTX does. Cable lengths can be an issue in these though.
