The laser point is moot given that we don't have any workable lasing mediums... Lasing mediums we do -- ruby, I was incorrect -- but we don't have any gases to put on the arc lamp. Unless we convince samchiu2000 to allow helium-3, and even then it lines up horribly with the ruby spectra lines, not really workable.

Biggest challenge here seems to trying to find anything at all that would act as a radshield...at the moment I'm using 40cm silicon slabs, but thats not really ideal.
Also, nuclear reactor design with the materials we have for thermocouples is going to be...interesting.
Would be tempted to just go with conventional rocket propulsion, except none of the fuels are ok.

Don't know about oxygen NTR especially since high temperature oxygen is one of the most dangerous chemicals in existence. Delta V doesn't super important, so H+LOX shouldn't be too much of a problem.

Yeah, I'm working with a Water NTR atm.
Could I have a hydrogen fuel cell for power please? I don't think its feasible to build a nuclear reactor out of this stuff...

That sad yield strength of iron is disappointing. It doesn't afford much delta_T at all. I'm fighting just get into the MW range.
Regarding economy of scale are thermocouples the reverse where multiple reactors with more relative surface area are more efficient? Because the theromocouple is getting big. The counter is that reactors require crew.

The counter is that reactors require crew. The (cheesy) solution I'll use for this challenge is to leave the power management to computers. That is, built a battleship-drone with weapons, all the reactors I want, and a drone control module, and a low-powered human-crewed vehicle to launch it.

Drones have a crew requirement based on the crew needs of the modules on the drone. Well I guess it does work because the combat drone itself doesn't care about the mass of the station that launched it. But you could use a bunch of simple ~100kW drones with low crew requirements without needing a large crew of drone operators.

I agree that it is weird that if I put hundreds of reactors on the mothership it requires crew, and if I put it on a large drone it doesn't -- making a solution like this is both funny and putting a light on this. I could also use smaller drones, except the requests for more energy in this thread made me want to solve the mission with a coilgun with 1 MW of power, just because. We'll see if I do that or decide to do something else.

Here's a submission. It is slightly less cheesy than I expected, because turns out that operating these drones still requires 177.1 people. Still, it is very much in the spirit of "put all your weapons on the large drones and send them over". These "Lunar Drones" come at 3.95 Mc and 435t each. They have a main "Lunar Coilgun", which fires 1g iron projectiles at 13.1 km/s, and nine "Lunar Coilgun PD", because I felt fancy / to provide some semblance of point defense, but not actually used in this mission. 10 of these are mounted in a launcher module, and then a spaceship / mobile platform is built around it (7.41 kt, 48.1 Mc -- it still fits the campaign mission budget). Make sure to launch one lunar drone at a time. These ships outrange and overpenetrate the gunship on the mission, allowing us to destroy all modules before the gunship has a chance to engage.

Well the task is simple : to build a warship with material found on lunar! I propose this challenge because i saw many design on forum use rare material in large quantity , which is not realistic , so i have a idea of using common material found on the moons and planets in sol~ Limitation: .You can ONLY use these following materials: Calcium , Aluminium , silicon , oxygen , iron , magnesium , potassium , titanium , uranium , thorium , water , hydrogen and aluminium oxygen. It sound a lot , or is it? (Exception of nitrogen in crew module.) .It need to defeat the mission "Main belt extraction" of the core game to be consider as a successful warship! I may post a design of my own later. AND WELCOME ANY DESIGNS FOR THIS CHALLENGE! The elements widely used in current meta designs are not uncommon in the solar system - IF assuming extraction technology as sophisticated as implied by CoADE manufacturing. As for your element list, that's actually pretty good to simulate a bunch of Lunar rebels with crude industrial tech and extreme lack of trade shipments. I'll take up your challenge whenever I get a break at work (after q-switched's next patch, of course) and see if I can build a good warship around your limits.

If we make ruby lasers, can we use trace quantities of materials for frequency doublers?
