Engine to produce another resource?

[KerbMav]

Is it possible - through simple config file magic - to get an engine to produce a waste product while burning fuel, proportional to the amount of burnt fuel?

The thing though is that in an engine, the waste products are usually shot out the exhaust, which is the nozzle for rockets.

However, the resource conversion is done all the time in life support mods or converters like those in Karbonite or MKS/OKS. So, it should definetly be possible. I'm not a modder, so I don't know how to do it, just know that it should be possible.

Out of curiosity, what kinds of waste products are you thinking of here?

That function is technically possible with ModuleResourceConverter, you could set it to produce one resource while consuming LF, but I don't think you can tie that to the throttle (or staging, for that matter). You would probably have to write your own module for that.

Nuclear waste. Used rad.elements from a nuclear engine.

Maybe take a page from the way the reactors in MKS/OKS and FTT work? RoverDude has a very open license on his stuff, so I'm sure he'd be happy to let you use the code from there if you ask.

That's brilliant.

Hm, interesting, will require some number juggling for sure, but worth a try, thanks.

Mh, yeah, ahm, no ...

Sorry, I am just able to understand MM's language to mod my parts, but coding is way above me.

Another way is to have the engine also consume the resource you want it to spit out. But instead of drawing a positive number of resource, use a negative value. When the program subtracts the value from the tank, it'll be subtracting a negative, and will effectively add that resource in according to fuel flow rules.

You Genius You!

The raddish (radioactive rubbish ... la-la-la) does nothing negative, but at least it does something: The engine does not loose weight, just uses up its reactive mass!
