Yeah, by all means there should be no heat transfer without a medium like air.

There should, will and must be heat transfer by means of radiation, thats not some Sci-Fi stuff but very real.

i think this thread is kind of a mess now.

can we like, discuss about game mechanics first then slap a layer of lore later?

As for OP, i think gauss is good in terms of stealth. after all in the spirit of design, it is a slow firing, high damage sniping weapon. the mass of sparks and the loud thump from the impact along with the red damage indicator is good enough to tell the victim where the rounds are coming from. let alone the sparks created when the gauss is fired.

if the player is experienced enough to hide their position after firing the gauss rifle, i think they player should be rewarded with skilled use of the weapon.

i feel this is one of the ways the skill ceiling can be raised.

That's when the substance is emitting particles like photons, etc. For example when a material reaches incandescence temp, it will glow and radiating heat outward. Normal materials do radiate black body radiation but not at the scale that would cool a mech. Laser heatsinks "[color="#000000"]a laser heat sink uses lasers to excite the hot exhaust gasses to a higher-energy state, converting the infrared energy of the gasses to light which is then shunted out of the 'Mech via a series of highly polished surfaces. " which is even weirder because it adds even more energy but still uses a medium.

I used "sci-fi" stuff to describe it because there is no conventional way that it will work in the current technology. Mobile Phones were "sci-fi" stuff at the time of tesla.[/color]

Regarding Laser Heatsinks, I guess the creators got the inspiration from "laser cooling".

Laser cooling is used to study Bose-Einstein condensate but it can't be used practically for large scale applications I imagine.

i think its a form of sublimation cooling, but then again the laser is going to make more heat. laser ablates a hot brick of metal or some other heat carrier. i dont see it as very heat efficient. its sort of like regenerative cooling in rocket engines, where you take the heat out of the bell and combustion chamber by pumping the liquid hydrogen around it. then the heat goes out the nozzel with the exaust, keeping the engine from melting.

other ways to get heat out of the mech is to evaporate coolant, or through ground coupling (provided the ground is colder than your mech). you would need extra coolant (as if heat sinks had ammo). you can also use radiators for radiative cooling, but that involves a large bulky surface area that doesn't fit on a mech very well. also if hpg is that bad, vitric would be impossible.

You can actually just **** up the properties of a material by lasering it. I wouldn't be surprised if excited a certain materiel with a laser can excite into giving off more heat. The laser heatsinks give off a distinctively bright light, don't they?

Laser physics are super weird.

The basic principle of laser cooling is actually pretty simple, which is that we use laser beam (photons) to slow down the movement of particles in gas. The devil is in the details.

There we go. That's what I was thinking. Thanks for the laser lesson. :0

Still its there so "no heat transfer" is plain wrong.
Most likely it couldnt cool the mech all by its own but at 350K surface temperature it should dissipate close to 1kW per m² to space. Plus much less to ground.

Another way of exchanging heat without a medium like air is plain conduction. In HPG the mech is standing on about 260K cool surfaces, especially those made of metal could be useable.

Btw, how much heat is one DHS supposed to dissipate?
