So then the theoretical minimum amount of energy needed to hold up something, as in no change in height, is zero
-
What is the theoretical minimum amount of power needed to hold up 3.3 tons?
-
IF that turns out to be true, we WILL have flying cars, silent, reliable, liquid hydrogen powered, back-to-the-future, flying cars.
-
What photon drive can give 0.1N per kW?
-
That was one of a particularity poor set of images, who ever made those images was a idiot... oh wait I made those images!

That quote is from the Watchmen, but it is horrifically fitting right now.

Eve SSTO: Now with cheaty goodness!
RuBisCO replied to GoSlash27's topic in KSP1 Challenges & Mission ideas
I'm not a contender because I'm not using stock parts, but this is my Eve SSTO for delivering parts to my Eve base and shuttling crews and life support: Balloons are more realistic then infiniglide or gyrocopter, I can float to 30 km, from there I can get to a 110 km orbit with just ~4500 m/s of DeltaV using one big KR-2L. KW parts makes everything look slick, I think all that is stock (no including the KR-2L which is pseudo-stock) is the 2.5 m SAS ring, solar panels and ladders. The robotics parts let me use half the balloons as landing gear. -
Why doesn't Tylo have an atmosphere?
RuBisCO replied to ThesaurusRex's topic in Science & Spaceflight
The space kraken lives on Tylo, it did not like the atmosphere so it striped it off, never mess with the kraken. -
Make a new mod "HL AirBases (Alpha)" that requires what ever other mod to make the floating base work.
-
Sounds great because something going wrong simply declaring a ship landed when it is in the air. Technically in the mean time I could try to build a base just floating less then KAS cable length above the ground, sort of defeats the idea on Eve of staying at room temp altitude (22500-23500 m) and is grossly unrealistic on Jool where room temp altitude is 44-45 km and "surface" temps are beyond anything realistically survivable.
-
Oh I can do it with KAS, but not beyond the KAS cable length. I did once make modified KAS cables that were kilometers long but that didn't work so well for the hook/anchor and floating base would become dis-entangled as one ship after their distance passed the physics mode distance, perhaps a mod that allows for things to stay in physics mod over ranges of several dozen kilometers and not just ~2. I've tried changing the "sit=FLYING" to "sit=LANDED" and "landed = True" but that only sort of works: the ship is no longer active, none of the parts respond, it is frozen, so clearly I'm missing what other changes being Landed does in the quicksave.sfs
-
I would like to make a floating base above Eve or Jool, is it possible to make a modification to the ballon code that allows for freezing a ship in mid air and declaring it "Landed" even though it is floating kilometers above the surface?
-
Just make a note of it on the first post something like "If the button does not appear in toolbar, it is probably because you did not install "TacFuelBalancer" folder inside the "ThunderAerospace", the path "...GameData/ThunderAerospace/TacFuelBalancer/..." must be present for the plugin to work with toolbar."
-
No I figured it out... sort of... one of my mods makes ion engines have horrible ISP and no thrust in atmosphere, which one, I don't know, I don't care, it can't be done.
-
-
Sure but getting over the inhabition of combustion by the water is difficult, energy is lost boiling all that water, ISP would be decreased. I once heard of the idea of aluminum particles in liquid hydrogen as a way to increase LH2 volumentric energy density without seriously decreasing the ISP, so I see no reason coal can't be mixed with a little bit of hydrocarbon instead of water.

A crude summary of the stages of scientific turthiness: Someone makes a claim = "BS" Someone makes a claim and reports it in a peer review journal = "Intresting, but probably BS" Someone test that claim and comes up with the same or similiar results = "Fascinating, perhaps this is not BS" Someone repeats testing of claim with variation and gets similiar results with a model showing what variation does = "Well this appears to be the scientific consensus" Someone repeats the testing of the testing of testing of the claim and gets the same results that fit within the model = "Established Scientific theory" Someone with limited education can be instructed to test and can validate the claim that has been tested, re-tested and modeled = "Fact" EMdrive appears to be at stage 2 or even 3. Of course to make it to stage 4 requires more 3rd parties to test and validate and publish their validations in peer review journals, if no one manages to validate or many manage to disprove it, then it falls back to BS. I like the dramatic though: because of the extraordinariness needed to accept this, for it appear to violate conservation of momentum and energy, something that has been stage 6 for centuries now. I think they are going to need a spacecraft run laps around the solar system before most everyone accept this as fact. A couple more labortory experiements are simply not going to do it to convince the scientific community or most of humanity. How it manages to work despite appearing to violate conservation of momentum, explain that to me after you have shown me it fly out of earth orbit and back, else why should I listen to BS?

... Is this somekind of echo chamber?
-
Well then what am I doing wrong for it produces almost no thrust and an ISP of ~52?

Stock nuclear air-breathing engines
RuBisCO replied to goduranus's topic in KSP1 Suggestions & Development Discussion
I don't think Interstellar Mod has a air-breathing nuclear engine in it. -
I don't think Ion gliders even work anymore, I tried building one one it got an ISP of ~50 on the runway.
