Atmospheric fuel cell.

Recommended Posts

I like the fuel cell, but I always found it annoying that you had to use LF+OX. Why don't we have atmospheric fuel cells and hybrid ones? Image result for generator

They're totally a thing!

Technically, we can sort of use engine alternators for this. Although it's wildly inefficient.

We can copy the part's cfg, rename the part inside, find INPUT_RESOURCE definitions and replace Oxidizer with IntakeAir or so.
The number can be also corrected after a test with an air intake.

Then we have both.

Hmmmmmm... looking at alternator efficiency of engines, it varies quite a lot.

The wiki lists the Wheesley as having 0.0239 LF/EC at 4 EC/second. My data says more like 0.058. I suspect it's using beta era stats for the wheesley.

 

This compares rather poorly with fuel cell arrays, which produce 18 EC/s for 0.045 LFO/s. Meaning they get 0.0025 LFO/EC. Around 23 times the efficiency. 400 EC/LFO for the Fuel Cell but only 17.2 for the Wheesley.

I think modifying fuel cells to use intake air instead of oxidizer (don't forget to save the modified one as a separate part) could indeed simulate a generator like the one shown in the OP.

 

I think I'll go ahead and give that a try right now.

 

EDIT: Yup, works just fine. So if u don't mind a generator that doesn't sound and look like a generator u could just go ahead and modify the regular fuel cells to atmospheric ones.

can u check my code?

I'm not a coding kinda guy but given the fact that u went a little further in modifying the script than I did and mine worked fine I don't see any reason why it shouldn't work.

 

I'd say go ahead and fire up the game to see if it works, and if it doesn't revert to the original or start over.
