Some Russian space suits use these instead of a compressed O2 tank for their suits. Might be a nice little detail to add "flavor".
SFOG = Solid Fuel Oxygen Generator

Those models, yes indeed. The ones used on our subs are MUCH better designed and safer. But even ours must be monitored on a continuous basis. But, a couple TL's higher. It's an idea...

Ever flown on a an Airplane? The oxygen mask that they show you coming down from the unit over your head gets it's oxygen from a solid Oxygen Generator. How unsafe are they?

I had completely forgotten about those. Thanks for pointing this out Rikki.
Definitely. CO2 scrubbers and oxygen generators can be purely chemical, which means they can essentially be held in the 'weave' of a heavy-duty vacc suit. Such a thing is technically simpler and more damage-tolerant than any 'tank-strapped-to-the-back' approach, which will be key for any universe where jeff bloggs can get a medium passage for the price of an expensive contemporary holiday and five guys de-mobbed from government service with little or no fleet experience can buy a starship....
Also, you can hold more gas per unit volume with compounds containing that gas than with the 'pure' gas itself. Wierd, I know, but that's how chemistry works - volume is largely dependent on the number of molecules, not how complex said molecules are. This is why, if all you wanted was hydrogen, it would be more space efficient to carry liquid ammonia (NH4) than liquid hydrogen (H2).

Great info! Also, like you mention locarno24, NH4 (and H2O) are more Hydrogen dense than LHyd itself. I use for storage in my game. But, has to be processes before used in a jump bubble. So, used for PP fuel & maybe a 2nd jump worth of H2 sitting in a collapsible bladder. Room temp rather than cryo.

I read somewhere that it's possible to store hydrogen in a more denser configuration.

But, too much trouble. Ammonia or water is much better.

So, what would TL12+ candles weigh and cost (if they aren't already in the rules... I am away from my books)?

They have never been in the Trav rules. 1 liter sized would be a couple of kilo's. Probably cost Cr20. Last for 8-12 hours for a person. TL 12+ would be cheaper and last longer probably.

I vote for skintight elastic suits and brass brassieres. Do we wear codpieces?

Hopefully NOT if you are also wearing brass brassieres. :lol:
