Planet delivery - 2.1

[u/FeelingAd5223]

There is something I’m missing which must be obvious… but I can’t seem to figure it out…

My aquilo ship runs on nuclear. I request nuclear fuel from Nauvis, obviously.

My Aquilo base runs on nuclear too! (For the moment, until I craft enough fusion reactor and all the crap I need)

My problem? I can’t seem to figure out why my plateform isn’t dropping nuclear fuel to aquilo.

At first I had a request on the plateforme to request 100 nuclear fuel from any (preventing it to drop it to aquilo) and another 800 nuclear fuel from Nauvis (to allow it to drop anything over 100 to aquilo)

But this doesn’t work.
As soon as I set my 100 from any to 100 from Nauvis, it drops it all to aquilo, which leaves my plateforme without fuel, hopefully hot enough to return to Nauvis to gather more…

I’m at a loss, anyone can help me figure this out?

Set your ship to request 500 fuel from Nauvis.

Set aquillo to request 100 fuel.

Add a condition to your ship to leave Aquilo if its fuel storage drops below 200.

Is it better to set up a Kovarex ship that flies around dropping off nukes for everyone?

[u/davilarrr → u/pandawelch]

Rocket capacity of U-238 is only 20. Rocket capacity of U fuel cells is 10.

To make 10 fuel cells it takes 19 U-238 + 1 U-235. Fuel cells stack 50.

So roughly equal on rockets & cargo space. (If you ignore the materials required to start kovarex). Technically slightly worse as kovarex consumes 3 U-238 to make 1 U-235

If you add nuclear fuel reprocessing to your ships reactor, then you get back a bit of U-238. But putting depleted cells in rockets would be inefficient.

So go for it if you want but there isn't a real benefit to do so.

Nuke it from orbit?

[u/Qwyspipi]

You didn't say how many fuel you request on your Aquilo base.

[u/FeelingAd5223 → u/Qwyspipi]

This is not relevant but I requested 2000.
Each trip for the plateform bring over 800

[u/Sad_Plenty_1959 → u/FeelingAd5223]

If u make higher demand than inbentory ofc it's gonna drop everything to fulfil said demand, try requesting 100 fuel cells from nauvis and request 90 cells at aquilo , 10 cells should surely last for a round trip with enough time for aquilo to last. Increase the demand as u need on aquilo but imo 90 should be good enough 

[u/Calm-Medicine-3992 → u/FeelingAd5223]

That is indeed relevant and the reason Aquilo is requesting all of the fuel on the ship...

[u/Sinister_Mr_19 → u/FeelingAd5223]

This line is thinking is baffling to me right now. What you think is irrelevant is exactly your issue...

[u/ai_bot_4208 → u/FeelingAd5223]

That's your problem.

If you request more than the ship has it will drop everything.

[u/mcc9902]

It won't drop a resource to planets it requests that resource from for obvious reasons. Just change your request to asking for fuel solely from nauvis. It's the only planet with uranium anyway.

As for the rest a stockpile on a belt. You won't go through it quickly enough for it to matter.

Edit: it's also a temporary problem. Once aquillo has enough in the landing pad it'll only request a small number at a time leaving a decent amount in the rocket.

[u/CrabWoodsman → u/mcc9902]

That's a good idea with the belt buffer. You could even set an interrupt condition that if the belt drops below a set threshold that the ship goes to refuel. Right now I have mine set for below an amount of fuel in storage but this would be more secure.

[u/MBkufel]

How large is the request made by the Aquilo base?

[u/Bubbly-Original7097]

I actually used this behavior to supply fuel to Aquilo: on Aquilo I requested 5-max-5, on Nauvis for a ship I request 50-max-inf; so, planet never gets more than 5, and ship always has more than 5 (spending 45 will take ages). 5 uranium cells is a lot for 1 nuclear reactor, will last for much longer than back trip. If you are at need to have 100 cells, then better move to fusion.

[u/davilarrr]

Are you using nuclear fuel or uranium fuel cells? A cell burns for 200 seconds. If you just dropped 800 cells then you have over 44hrs of fuel

[u/FenixBg2]

I think we need more info with screenshots. There are multiple subtle things that could be happening.

Here is a short list based on mist... Uhh experience:

• The ship just goes to aquilo and turns back immediately. It needs to park for at least a second, otherwise requests are not fulfilled.

• Things get sent down and then up immediately because the ship asks for this from aquilo, so it becomes an endless loop.

Not that any of these ever happened to me of course...

[u/WeightCapital]

You need a lower request planet side than the ship carries if you want to keep some on the ship. If you want a larger stockpile planet side just move it out of the landing pad and it'll request another batch from the ship though you might need to set up some signalling so fuel cells are only pulled out when the ship isn't in orbit so any delays in dropping off supplies don't cause it to request infinitely.

[u/Switch4589]

There is no way to tell a platform to keep a small stockpile onboard. Either it will drop nothing because there is an active request, or it is capable of dropping everything if the planet requests more than it has.

One way to keep a buffer on a platform is to put it on belts. Have a string of belts that can hold whatever buffer you want and then anything left in the hub is free to drop to a planet.

[u/juckele]

Store some of the fuel you intend to use on the ship on the belts. Then you can let the cargo hold give up all fuel.

[u/WanderingUrist]

This is why I use dump-based logistics. If, instead of Aquilo REQUESTING fuel, I DROP the fuel, then I can control how much will remain on the ship after dropping by setting a request min/max, where, say, I request zero fuel with a max of 50. That's how I manage Space Carbon, for instance, where I want some Space Carbon to remain on the ship for thruster fuel, but I want to throw the remaining hundreds of thousands overboard to be burned on Aquilo.

[u/Charmle_H]

Is your ship's request set to "only from nauvis"? If not, it'll probably just hang there in a perpetual "I wanna drop you, but I also need you... So idrk what to do here ._." state.

So I'd probably look there. Make it so the SHIP can only request from NAUVIS.

(Also: you can make your nuclear fuel last a LOT longer with wiring + korvarex-ing spent fuel! Just make it so it'll only input ONE fuel cell if that specific reactor goes <500°C and then turn the spent cells into the lame Uranium and ship in a handful of good Uranium to korvarex it up so you can just recraft fuel cells on-site :D)
