Rules Only: Alternate Methods of Life Support Recharge?

[Fritz_Brown]

Good suggestion, timerover. Will they provide enough voltage/current to move airtight hatches is the only question?

Yes. Should just be a question of correct sizing.

I don't recall seeing any size/mass/cost infor for RTGs in Traveller materials - maybe in TNE? GURPS has info in several places: GURPS Space, Terradyne, Transhuman, and Vehicles at least. If you don't have access to something useable, let me know and I'll post some base numbers and you can scale as needed.

The three on Voyager were suppling 450 watts of power, so if you assume a more efficient energy conversion system which is better than about 10%, you should manage okay. Another option would be a back up close-cycle internal combustion generator, using hydrogen and oxygen for fuel, or a high-efficiency fuel cell.

You guys are great! Thanks.

Good point. This is an underground facility, and well-armored. The atmo ducts also have very sturdy cutoffs at every junction so any section can be totally sealed.

Did you ever get this built? I have some information from the US Army Field Manuals on Field Fortifications on what it takes to protect against different levels of attack.

Plumbing!

Airtight doors should be run off normal power and be designed to close on loss of power. For use in loss of power situations you would probably just have a manual handwind. Emergency power would probably be for life-support, comms, crtical controls etc. You could use a mix of RTGs, high tech batteries and compact fuel cells for the emergency power source.

It's still sitting at the 90% complete stage. Two of our group lost their mother a month or so ago, and it put the damper on our spirit for RP. But, it looks like interest is back.

Yep. I have to decide where the overflow point is, since this place has been shut down, I'm sure the water in the pipes is frozen.

Good point about manual cranks. Will make them sorry they left a couple of PCs behind, maybe. :smirk: Alarms will also be on emergency power. :devil:

Oooh, busted pipes! Lots of busted pipes!

They do not have to be big, just large enough to provide a trickle charge to a set of batteries at each powered door for 1-3 cycles of open/close could work.

If it was a planned shut down, they will probably have drained the pipes into a resevour.

Come to think of it, they may have drained the atmosphere into tanks as well if it was a planned shutdown.

Depending on the amount of water on board another potential short term source is air / oxygen dissolved into that water. After all, fish breathe this way so if you simply boil the air out of the water leaving just the water you get an air supply.
