Ok I understand you now. I'll poke at this and see what I come up with. Seems like a fuel feed thing that could probably be sorted easily once identified.

First ten minutes is on the ablative nozzle (better late than never??). When you say what exactly do you mean? Do you mean they draw fuel (pvc) from a central source or is something messing with the laser? (a single laser powering multiple engines may be a bit tricky as it will have to divide between them all. still should be doable with ... you guessed it, moar powa!)

In the mean time, to get you started, the ablative nozzle is like a receiver in that it has a power receiver interface and needs to be activated in addition to activating the engine. low thrust in atmo. better in vacuum. use a gigajoule(s) laser to boost in atmo.

Thank you for pointing that out. I had forgotten to include the ablative nozzle. I'll make sure it gets a tutorial asap! Been a while since I messed with that part.

Part III of the Beams!

kspie doesn't have a way to convert resources into LFO as stock liquid fuel and oxidizer are of unknown composition (i've heard people say it's Liquid H2, kerosene, cyclohexane, etc). stock mechanic of mining ore and converting using stock isru will provide you with LFO.

Thank you so much. I ran some tests using that and yeah, going with convection radiators for ocean power stations from here on out, hands down! Also, here is part II. All about basic relay use. Note these designs aren't meant to be copied but were chosen to illustrate functionality and be able to be seen on screen. A player's actual relays will/should vary. i have no idea why sometimes youtube gives me a clear thumbnail and sometimes gives a very low res thumbnail. video is uploaded in hd

Beam power tutorial from the exact point where beam power becomes possible in the [unkerballed start] tech tree. Long because a lot of folks have asked me not to skip over or fast forward through builds. So, I take my time and develop microwave launches from the ground (err ocean?) up. Take a look, feel free to question/comment/criticize. Part II coming as soon as I get better at low tech relays. Need to do more research.

I figured it out. I was trying to use an isru unit at first but quickly found that the science laboratory extracts deuterium from an ocean using the 'start centrifuge' toggle. Had a request for another, more in depth, look at fusion propulsion so here is a peak into the research and development process employed by my brave Kerbals:

I did notice the science laboratory still has the 'activate centrifuge' option. Which, if I recall correctly, is for separating out heavy water from water. Testing this right now. edit: Aha! I found it. Ok so the science lab turns water into Deuterium. about 43.5MW to get .94 Kg/hour. This requires the vessel containing the science lab to be splashed down. It seems to also work whether I have intake drills or atmospheric intakes open or closed so might be independent of intakes? But yeah, splash a science lab down in an ocean and click 'activate centrifuge' and it will produce Deuterium until the ocean runs out

@pmborg Firstly, I really really like that spaceplane/starship. It's so cool. Secondly, I owe you an apology. It took me a while to get around to testing because of rl stuff but once I did I realized I was speaking from old knowledge. I went out to the ocean of Kerbin to scoop up some deuterium and ran into a surprise. There wasn't any. I would have expected at least heavy water oops. So yeah, my apologies for speaking before testing. Here's a screenshot! @FreeThinker Maybe I'm losing my mind in my old age, but, I feel like harvesting Deuterium from the ocean was as easy as pumping intake through a processor. Did I miss something?

I did read the article and found it interesting, for sure. Thing is it uses a general statistic that doesn't actually represent deuterium distribution [variances] in the universe. On earth we get an average of 33 grams of Dt per cubic meter of sea water, or about 156 atoms of Dt per million of H. Distribution in nature, ie all the Dt in nature formed from the big bang, is about 26 atoms per million. Much much less. Studies of comets show a similar ratio of Dt to H as in Earth's oceans, giving confidence to the fairly well established theory that our oceans came from comets. Jupiter, on the other hand, has a ratio that is in line with the norm of 26 atoms per million, not very comet like but very universe like. Then there are observations of gas clouds that contain between 5, 15 and 25 ppm depending on factors such as nearby novae and such that would have scattered/vaporized/frozen the Dt making it undetectable by spectral analysis. "The deuterium/protium ratio of the comet 67P/Churyumov-Gerasimenko, as measured by the Rosetta space probe, is about three times that of earth water. This figure is the highest yet measured in a comet.[6]" -wikipedia https://en.wikipedia.org/wiki/Deuterium Ok, long winded, I'll get to the point. It is not reasonable to expect every ocean in the universe to have the same Dt ratio as oceans of Earth as those ratios are not even a constant on Earth or Earth's neighbors. See: https://en.wikipedia.org/wiki/Vienna_Standard_Mean_Ocean_Water The chromatograph science part(s) included with kspie do an admirable job of modeling this in game, in my opinion. I'm not saying don't do what you are doing. You get points, in my book, just for tinkering and making the change and the modules. Kudo's! I just wouldn't want someone that hasn't tried the included part(s) out to think that they don't work as expected.

@pmborg Perhaps try out the liquid chromatograph science part. It will give you a % distribution of elements and molecules present in a body of water. You'll notice if Deuterium distribution amongst Laythe and Kerbin is in line with expectations using that part. Additionally the gas chromatograph will confirm expected distribution in atmospheres of Kerbin, Duna, Laythe, Jool, and Eve. I can't speak to planets added by mods but the few I've downloaded and tested in 1.7.3 (not extensively) are a bit mixed. Some have absurd amounts. Some are missing it entirely. As for stock planets I feel it should be about right but I'm no expert. Perhaps that should be my next video. Taking ocean samples from the three stock oceans....hmmm.... Rockin spaceplane, by the way!

@pmborgI'm pretty sure 'Ocean Extraction' works for that as long as your universal drill is submerged and pulling in 'intake liquid' which is a resource the drill itself will carry in small quantities. About enough for the ISRU to extract goods from it much like regolith processing. I know the All-in-One ISRU does ocean extraction, I'll have to check to see which dedicated units also do ocean extracion. By submerged I mean just the end of the drill under the surface. Don't have to dunk the whole thing.

built it in situ! landed a construction ship, dug up a bunch of stuff, surveyed the site and plopped it down full vid on the process is the one posted on Dec 28th. It's like an hour and 45 minutes long though so maybe double tap that fast forward button. glad you like the tutorial, i'll have the next one up soon!
