Just make sure to do the yield / cost comparison to make sure the ratio is higher before saying something is a new cheaper replacement heh. I am a big fan of min-maxing for cost myself as well.

Can also protect turrets with other turrets. qswitched could get get an extrusion height option to allow noncheesy superfiring and wider attack angles without using larger turrets? Put a radiation shield in front of the ship / turrets to act as armor for maximum cheese. (ship still under development needs a bunch more km of lasers to justify the enormous rad shield ) But really turrets should run a line of sight check before being able to fire to get rid of exploits like this.

Thanks, and earlier you said the first few were optimized for aluminum mirror with calcium radiators. ive been using boron nitride, should i switch ? you should pick the radiator comp off the outlet of the thing you are supporting it (if you want to save mass and cost). Here are the optimal radiator compositions by temp that they can handle Lithium 0 K - 452 K 59.1 tons / 100,000m^2 239,000 c / 100,000m^2 Calcium 425 K - 1110 K 172 tons / 100,000m^2 1,000,000 c / 100,000m^2 RCC* 1110 K - 2270 K 194 tons / 100,000m^2 14,700,000 c / 100,000m^2 Boron 2270 K - 2348 K 230 tons / 100,000m^2 4,000,000 c / 100,000m^2 Boron Nitrade 2349 K - 3244 K 233 tons / 100,000m^2 4,890,000 c / 100,000m^2 Amorphus Carbon 3245 K - 3913 K 233 tons / 100,000m^2 5,200,000 c / 100,000m^2 Pyrolitic Carbon 3913 - 3920 K 249 tons / 100,000m^2 5,580,000 c / 100,000m^2 Halfnium Carbide 3920 K - 4158 K 1,410 tons / 100,000m^2 86,800,000 c / 100,000m^2 Tantalum Halfnium Carbide 4158 K - 4486 K 1,620 tons / 100,000m^2 282,000,000 / 100,000m^2

The silver option maintains the beam intensity but doesn't get nearly the same outlet as the moly setup if you wanted a middle ground option:

I can give it a higher melting temp mirror which would increase the outlet and reduce the radiator surface area but the total cost and mass will go up very significantly. Atm it is optimized for the aluminium mirror with calcium radiators. The only other way to get less radiator surface area is to use less power with a larger aperture to make up the intensity difference (aka the enormous laser) but you wanted small heh. I'll tinker with a higher temp outlet since you want to keep it small and see if I can make anything reasonable but expect to see a huge total price and mass increase to accompany the lesser radiator surface area. Calcium radiators ? Oh dear, ive been using Boron Nitride. Here is a 1928 K outlet laser which should greatly decrease needed radiator surface area at the cost of about half the intensity:

jasonvance, i will think about the huge lasers, but i was looking for smaller ones, becuase the had to hit in the spaces avialable for them on this ship Thanks a ton for the lasers :-) im going to incorporate the 400 MW lasers, in an even larger design, maybe a laser battleship. is there anyway to make the laser's radiators more effecient ? (so i could use less ?) I can give it a higher melting temp mirror which would increase the outlet and reduce the radiator surface area but the total cost and mass will go up very significantly. Atm it is optimized for the aluminium mirror with calcium radiators.

I also threw together a 400MW laser that followed the same metrics as the others in case you didn't want to build enormous laser arrays of enormous lasers, even though they are cheaper. I hope you will at least give the cheap big laser a thought though since it did take a lot of math to figure out. Aperture size: 2.357

Thanks jasonvance :-) any luck on the 250-400 ? Well I can throw together one for that power input and make the laser small as a result but I wanted to present a cheaper alternative (when taking power generation mass and cost into account). This 19MW enormous laser will produce a 100MW/m^2 intensity at 1Mm for the cheapest possible total cost. For total cost (power, radiators, and the laser itself) this comes in at just 22,952c and a combined mass of 3.432 tons. I would make the argument that if you want the most dps / cost and want to use 380MW 20 of these things on the nose of your craft would be the most optimal fit for only 459,040c. For that same cost you could only fit 5 of the 150MW medium lasers (which would take 750MW). Without even taking into account this beam intensity is 3x stronger than the medium laser. Aperture Size is: 9.108 Turret inner radius size is: 19.321 Coolant Pump rotational speed: 114.2

I was going to do some math to figure out what the optimal laser would be for the heavy one to get the cheapest overall 100MW/m^2 beam @ 1Mm so that one will take a little bit longer those 2 should be fine for what you were looking for though.

Here is a light laser within your spec of ~5m diameter and T50MW. The one stat that is rounded (and not listed properly) is the aperture which is 1.131 (not 1.13). *fixing this atm standby* Thanks a ton Fixed now I forgot to set the right inlet for the coolant originally (which was making it way heavier than necessary).

Here's my improvement on the 13.9 watt hydrogen (Which I'm pretty sure was based off of my design in the first place), can be neutron fluxed all the way up to about 30 watts I believe but I don't do that because I use it on the smallest possible radiator. It's the same price but 2 grams lighter. Pretty sure you based it off my design (as you stated in the Unlimited Power thread) and then I improved it further by going Hydrogen... This is the reactor for my microdrone, been playing around with it a lot since it's most of the cost of the drone. Jasonvances small ethane reactor gave me the idea to use a criticality changing coolant to make the chamber smaller, which shaved 8 grams off of it. Anybody want to give a shot at making it lighter/cheaper? Needs to be at least 12.5 watts or so.

Mainly just need to know what outlet you want to run but this is more in your energy ball park as an example: This is great! Could I see the 1 MW reactor too please? If it fits the size requirements, I might be able to stretch my other limitations for that much power. Thanks a ton! It is listed on the main thread but here it is again you can add as much boron nitride neutron reflector as you want to lower the radiation hazard:

Hey could someone who has experience with reactors help me with something? I'm trying to design something that produces ~10 kilowatt+ range energy, but with the restrictions of being no larger than 50x50x50 cm, weigh no more than 25-55 Kg, and most challengingly have minimal heat output temperatures, without creating too much excess heat. And as if that wasn't enough, I would prefer as low radiation leakage as possible, but it might be easier to just make a ship and surround it with some Lithium-6 This is going to help with part of my next big thread, so you'll see why I need these parameters then (If you don't figure it out on your own by then) Thanks Mainly just need to know what outlet you want to run but this is more in your energy ball park as an example:
