Blazing Falken Posted September 15, 2019 Share Posted September 15, 2019 ***EDIT NOTE: The thermal stack bug is present anytime you split a stack, it's not just for rails. SO! There is a bug where the stack that is loaded into a conveyor that calculates the heat of the last packet as if it contained the original full mass of the stack. Preheated pills to 135.5c and 135.6c. The first packets in the conveyor are converted to 19.9c and the last retains the original temperature. The first, middle, and last 20kg pill packets and the control 100kg stack are encased in 99,999kg of 326.9c of copper ore. Temps of various points. The fun begins! Who will win the race? Now it's time to unearth the control pill stack. Surely they can't be the same temperature while having 5 times the mass, right? That would be a big fat 100kg yes.

BLACKBERREST3 Posted September 15, 2019 Share Posted September 15, 2019 I'm trying to rack my brain for practicality. If you wanted even more efficiency out of the chill pill, you'd have to do a shutoff-filter to separate the hot from the not while also precisely controlling the timing and flow of the rails. Spoiler Not sure if I should add this under heat transfer or building interactions. Link to comment Share on other sites More sharing options...
Blazing Falken Posted September 15, 2019 Author Share Posted September 15, 2019 It probably falls under heat transfer better than interactions, in my opinion. I think why the fridge helps in my builds, it acts as a reset before the rail loader so that all packets are outbound at 20c regardless of returning packet temps. Not much if any efficiency to be gained for a whole mess of automation (vs. none at all). Using this method to efficiently create heat might be more involved. Practicality? It's basically temporarily altering the SHC so this could be used to both heat or cool more efficiently when applied properly. I am working on a useful heating build as we speak. I'm not sure how long it'll take till I'm satisfied with it but as usual, will post when ready. Link to comment Share on other sites More sharing options...

Blazing Falken Posted September 15, 2019 Author Share Posted September 15, 2019 I need to refine it and make a new post later, but it's absolutely working flawlessly. Self-powering, power-positive, self-cooling, and cooling-positive. What more could you ask for? Spoiler Battery bank on bottom right is for excess power and is isolated by transformer.

wachunga Posted September 15, 2019 Share Posted September 15, 2019 I think this is a bug with debris in general. A debris pile doesn't seem to update it's thermal mass after part of the pile has been removed. I've noticed this with ice debris. Typically I'll make a simple ice melter setup by having a bunch of compactors for small amounts of ice in a tank of water. Periodically I'll gather a bunch of ice into a large debris pile that gets swept into the compactors. The small amounts in the compactors melt quickly and dupes refill the compactors. The main debris pile melts as if it had it's original mass even when it's down to almost nothing. A picture may explain better. Started with 200 kg of ice debris. 50 kg went to the center compactor, 100 kg to the right compactor, and 50 kg left on the floor. After a few moments, the difference in temp of the 100 kg compactor ice was half that of the 50 kg compactor ice, as expected. However, the difference in temp of the 50 kg floor ice was one fourth that of the 50 kg compactor ice, as if the floor ice was still 200 kg. I haven't bothered testing other types of debris piles but there is potentially a huge exploit here. Given the other debris bugs, debris is very poorly implemented and super janky.

ZanthraSW Posted September 15, 2019 Share Posted September 15, 2019 Is the incorrect thermal mass preserved across save/load? Link to comment Share on other sites More sharing options...

I'm not sure yet, but even so, the thermal energy in the stack isn't infinite and will have to be recharged periodically. I'll check later if nobody else does. 23 minutes ago, wachunga said: I think this is a bug with debris in general.

I'll have to see if I can rework my design to ditch the long rail chain if it works out as effectively. Link to comment Share on other sites More sharing options...

I believe there is no specific debris handling in code so this seems to be bug with splitting stacks in general. That means also stuff that is in containers is affected. I put 3100kg hot gold into one container inside cold water. That made it one stack and then I moved 1000kg into one, 2000kg into another, and left just 100kg in original storage. 100kg was loosing temperature slowest at speed of 3100kg. Moving that 100kg into another container fixed it to correct 100kg behavior. Spoiler Link to comment Share on other sites More sharing options...
Blazing Falken Posted September 16, 2019 Author Share Posted September 16, 2019 Storage containers transfer heat with the tile they sit on, so you may want to use a metal tile instead. Without knowing the tile temperatures and keeping them separated via vacuum or other method, there may be other variables at work. Also, for the sake of discussion, debris and stack are basically interchangeable. Edit: I just tested, and yes, correct. Confirmed that the split stack retains the original thermal calculations. I used 4000kg split into 1kg, 3998kg, and a 1kg storage in vacuum on aluminum tile and the original 1kg conducted at basically same rate as the 3998kg, while the last 1kg changed rapidly. Cat's outta the bag, let's get to work abusing this. Link to comment Share on other sites More sharing options...
wachunga Posted September 16, 2019 Share Posted September 16, 2019 Just did a brief "calorimeter" test and can confirm that splitting debris/stacks generates effectively infinite heating or cooling. Limited only by how many times you split. Start with 100kg of hot diamond, put 99kg of that somewhere else. You now have 199kg of hot diamond heat energy. Pull 98kg out of the second pile and put somewhere else. You now have 297kg of hot diamond heat energy. Repeat ad nauseam. The challenge now is engineering a system to do so. The usual suspects should have a blast with this. Link to comment Share on other sites More sharing options...
