Craigjw Posted November 6, 2019 Share Posted November 6, 2019 I'm using the rocket exhaust to heat up some heat sinks and generate power. I'm wondering what the best material is to use on the heat sinks. I've used steel tiles on this build and next to it, i've filled in some with igneous tiles, which I'm expecting to melt when I move on to hydrogen. My question is, which tiles are best to use to capture as much of that exhaust heat as possible? Why do my dupes keep delivering Oxylite to the solid fuel tank when the rocket has already left? Thinks this is a bug. Link to comment Share on other sites More sharing options...
Hellshound38 Posted November 6, 2019 Share Posted November 6, 2019 If everything is vacuum sealed, I don't think it really matters. Since heat won't be lost. Although this assumes that the exhaust heat is an amount of energy rather then a temperature increase. I used Diamond.... because why not. Had to use 2 layer of Bunker tiles though, to prevent meteor damage. Link to comment Share on other sites More sharing options...
biopon Posted November 6, 2019 Share Posted November 6, 2019 It doesn't much matter. The heat under the rocket is given out as raw DTUs, so material with lower SHC gets hotter. Igneous is pretty decent actually, as long as you expect to cool it. It may melt at 1400C instead of 2400C like steel, but steel will get 2x as hot from the same amount of energy, so which one's better? It depends on how quickly you want to harvest that heat I guess.

Craigjw Posted November 6, 2019 Author Share Posted November 6, 2019 This answers my question nicely. I will probably use the setup on the right with the igneous mix and save on some steel. Link to comment Share on other sites More sharing options...
Cybeon Posted November 8, 2019 Share Posted November 8, 2019 One of interesting options is water (actually steam when it reaches proper temperature) encased in steel/diamond tiles and some heat transfer plates inside. Due to enormous SHC it can accumulate a lot of energy providing steady heat flow. Even better would be a supercoolant, but it's unrealistic setup there is a video about that on youtube, though it's in Russian (sorry, i didn't find any English alternatives)https://www.youtube.com/watch?v=7ulCQR37Qn0&list=PLZgBoU1efUISGSg-6rJKYFllo2FzS3g0y&index=3&t=0s Link to comment Share on other sites More sharing options...

I have actually had a similar idea myself, where by either the space is filled with more and more water while it evaporates, or it could be done with ao a waterfall storage, then boxed in. Probably former method is easier. However, I don't think that adding 1 million tons of water is going to benefit so long as the heat can be dissipated in time before the next landing, as the heat produced from the rocket is a fixed amount and 1 million tons of water will just take forever to heat up.

melquiades Posted November 11, 2019 Share Posted November 11, 2019 i made this, and i could probably get away with placing more steam turbines: The more steam you dump into the chamber, the more heat it soaks. Link to comment Share on other sites More sharing options...

As long as you keep this thermal buffer in vacuum heat won't dissipate. And maintaining vacuum in/near space biom is not an issue at all. Link to comment Share on other sites More sharing options...
