I flew around my 2 TW powerplant. It outputs so much wasteheat when producing laser, that surface of nearby sea should melt ;^) Also RIP KSC. Assuming emissivity of 1 and no convection radiators can't get rid much more than 10 MW of waste heat per square meter. At 1 MW/square meter radiator has temperature of around 2000 kelvins - assuming ambient temperature of 3 k - deep space, if ambient temp is like 100 K then radiator would heat up to 2100 K At 10 MW/square meter temperature would reach 3644 K - near upper limit of upgraded graphite radiators! Even if upgraded radiators have emissivity of 1.4 (nanolathing), then 15 MW/square meter already is too much. Also what about radiative heating of spaceship, when beam is too spread out? Also nice radiator cheating: Can we just remove surface bonus and allow tweakscaling radiators up to 100 meters (radius/longest side of rectangle)? Deposing 1 000 000 MW of wasteheat (beaming extreme UV created by beam producer powered with 20m sized QSR can give you these numbers) requires radiator surface of ~100 000 meters squared (well sligthly less but still below 15MW/square meter). That is square of around 316x316 meters. Or circle of 178m radius.

Something not working then. That powerplant has 20m base radius and around 350 meters in height. Even KJR cant support that - had to use gravity hack (alt+f12) or to zero gravity or unbreakable joints/no crash damage As you can see on pictures LiD isn't used at all

How to deconstruct Lthium-Deuterium componud so I can use it in Stellatron?

Saw your post when I was editing my post. What about other fuels?

It would be nice to have fusion fuel tank since resource consumption isn't 1:1, if there are 2 different resources used in reaction. Such tank would have fairing, so you wouldn't have to design tanks for each reaction - part of it would keep solid material and other part - liquid material. Here are fusion modes from your table that uses more than single resource (removed singhle resource ones) Fuel Mode Reactors Types Tech Requirement Reactor Power Reaction Energy Reaction Rate Power Requirement Multiplier Neutral Plasma / Non Neutral Fuel Products Charged Particles Brems-strahlung Neutron Energy Ratio D-T Fusion MCF / MIF Fusion Power 1 1 1 1x LqdDeteurium + LqdTritium Helium4 19.3% 0.7% 80% D-He3 Fusion MCF Advanced Fusion 0,884 1.04 0.85 2x / 4x LqdDeteurium + LqdHe3 Helium4 + LqdHydrogen 79.13% 15.87% 5% D-Li6 Fusion MCF / MIF Exotic Fusion 0.889 1.27 0.7 6x / 9x LqdDeteurium + Lithium6 Helium4 18.2% 81.8% 2.5% He3-Li6 Fusion MCF / CBF Exotic Fusion 0.672 0.96 0.7 6x / 9x LqdHe3 + Lithium6 Helium4 + LqdHydrogen 0.1% p-B11 Fusion CBF Exotic Fusion 0.3458 0.494 0.7 6x / 9x LqdHydrogen + Boron Helium4 + LqdHydrogen 36,3% 63.6% 0.01% p-Li6 Fusion CBF Ultra High Energy Physics 0.154 0.22 0.6 10x LqdHydrogen + Lithium6 Helium4 + Helium3 41.9% 58.1% 0.1% p-Li7 Fusion MCF / CBF Ultra High Energy Physics 0.6839 0.977 0.6 10x LqdHydrogen + Lithium Helium4 75% 24.9% 0.1% p-N15 Fusion CBF Ultra High Energy Physics 0.1704 0.284 0.6 10x LqdHydrogen + Nitrogen15 Helium4 + Carbon 60% 40% 0.1% p-O18 fusion CBF Ultra High Energy Physics 0.1363 0.227 0.6 10x LqdHydrogen + Oxygen18 Nitrogen15 + Helium4 Since there is something called Lithium Deuterite can we have other fusion mixes for other reactions? Deuter-Tritium or Deuter-Helium3 fuel could be stored as one gas for example. Can this Lithium6/7 be mixed with Hydrogen/He3 just like LithiumDeuterite? What about fusion methane/water (containing N15/O18 respectively)? Also can Hydrogen+Boron be stored as one compound? Oo LithiumHydrate exists

Why universal tank set on compressed air doesn't refill from air intake?

I managed to achieve around 50% efficiency of turning energy into beam: 21 GW generated, 11 GW sent to Earth.

Structural parts still aren't resizable including heatshield radiator.

I managed to accelerate up to 20 000 km/s with EM drive! I would get higher speed if I took more He3 for tri-alpha QSR + EM + 20 ton of Hydrogen = relativistic DV, astronomical ISP and fairly low thrust. Is there any combination, that allows you to reach >10% speed of light while accelerating at 1g? Why I can't switch between all possible fuels in wakefield engine using infinite propellant cheat? Edit: you need to remove all tanks to make this cheat actually work - activated all cheats and now my craft is just engine + probe core + SAS Is it possible to make magic tank, that can contain any fuel/propellant with adjustable mass? Such tank would work only when infinite fuel cheat option is on. All thermal engines doesn't work without radiators with thermal cheat on, while they should.

What reactor/generator/radiator setup produces most energy per kg of dry mass? Lets say everything is fully upgraded. I want to make tiny EM drive powered craft ------------------------------------------------------------------------- If I wanted to make highest TWR ship what I should pick?

Why pure Hydrogen fusion mode was removed from table? Even though it wouldn't be very efficient, reactor could work forever when orbiting low enough for air scoops to be able to gather enough hydrogen.

Not even theoretical design of antimatter rocket capable to send 1000 humans into nearest star? This one still would achieve lower exhaust pressure?

I wonder what rocket could recreate conditions in Jupiter core - pressure of 3 - 4.5 TPa and temperature of 36000 K Sadly wiki doesn't say anything about density of mostly hydrogen core. If nozzle was one meter sized I bet we could roast marshmallows in middle of Antarctica hundreds meters from such exhaust, if you don't mind thunderstorm, hurricane winds and heat (probably hydrogen could burn somewhere nearby such blue-white plume)

Well yeah, but what about surroundings? How much of problem it would be. For example lets say this matter inside container is replenished (something like infinite fuel hack in KSP) and it is constantly flowing out. Are there any formulas on mass flow trough hole depending on matter temperature, density and pressure? Lets say matter leaving such container has composition, pressure and temperature of Venus atmosphere on surface - something like CO2 powered nuclear rocket from KSPI Interstellar. Or Jupiter core - how much destruction it would cause? Such container could be in center of earth with exhaust pipe opening on ice level few km under it to prevent it from flying away. Such pipe also would be magic - no energy would flow outside its walls, just trough hole. Portal would be just used to act as infinite fuel cheat. XKCD also was doing magic too like throwing balls at near light speed or creating portal to Narnia under ocean. This would be awesome volcano, but it would be something like constantly exploding Tsar bomb if its fuel source was core of Sun/Neutron star?

Well I would like direct my questions about "compressed hot matter in strong container suddenly released trough smallish hole to outside" to XKCD WhatIfs, but they post so rarely...

>.> English isn't my primary language I thought What If questions were allowed here including kinda breaking physics ... So this forum is like: Don't post "what if" questions and have good english lmao

Portal is used to feed magic container, that has hole of one meter size. Could be dug deep with magic pipe tunneling hot compressed matter outside to prevent thrusting away from place. Once hot matter is out, what happens to surroundings? For example this matter has composition, pressure and density of Venus atmosphere on surface or gaseous core of gas giant/star. On other hand it could be vacuum cleaner or just drain water from marina trench. Container is magic, so matter source is constantly replenished and there is no energy loss during matter transportion trough pipe. Once matter is outside normal physics resume as in good old XKCD Whatif

Why KSPI structural parts and probe core aren't resizable?

You can't use thermal/charged energy of QSR reactor for propulsion.

Can we have tweakscalable structural parts/radiator shield and probe cores?

I think there is no extreme ultraviolet option - 10 nm wavelength in this UV beam generator. Shortest available is vacuum ultraviolet of 100 nm.

So if I wanted to power tiny vessel with tiny receiver I should use UV light. Red Light wavelength (40% efficiency) : Spotsize = 380 000 000m * 0.000000700m / 80m = 3.325 m Near Ultraviolet (45% efficiency) (400 nm): 1.9 m Vacuum Ultraviolet (30% efficiency) (110 nm): 0.52 m. Looks like these transmitters are better at compressing these beams... or is spotsize added radius to beam? For example I use aperture of 80m to transmit vacuum ultraviolet beam, and this beam after traveling 380 000 km has radius of 80.52m?

I used biggest multibandwith transmitter. Its aperture is 80 meters for 10m radius.

Looks like this mod isn't compatible with KSPI - even if I add antennas it still says, that signal is lost. I use KRASH simulation to put unmanned powerplant on Moon with bigass transmitter, that can be used as antenna. Also I added normal antennas.

embrittlement is damage from neutrons and to stop it use Boron-Hydrogen or pure Helium 3 fusion. @FreeThinker If I want to have powerplant on Moon - a Stellatron using pure He3 for fusion and I want to transmit all energy to relays orbiting Earth at 36 000 km at geostationary orbits, then what beams I should use for maximum efficiency of energy transmission from Moon to surface of Earth? -------------------------- Moon surface B Powerplant on Moon, converting power to beam. 380 000 km from Earth R Relays, bouncing beams between each other, receiving energy from lunar powerplant and transmitting it to Earths surface. They are 36 000 km from earth on geostationary orbit. V Receiving vessel, <300 km above Earth - may be even launching or flying in atmosphere -------------------------------- Earth surface
