This is not solar panels. This is cooling radiators for their old nuclear reactors.

That wouldn't work very well... can't transfer heat that well into a vacuum.

Why do most Minatar ships have Solar Panels on them? Are they powered by the sun or something?

Ever wonder how things in space get hot being exposed to the sun?

I'll bet it's not due to convection.

The word "radiator" contains the clue that will help you.

Yeah... how exactly are nuclear reactors cooled again?

This is not solar panels. This is cooling radiators for their old nuclear reactors.

In space? Through radiation.

So the question is, how would you take the heat extracted from the secondary and convert that to a form that can be efficiently radiated into the vacuum of space?

By running it through a myriad of cooling surfaces GÇö the more surface the better. A standard passive cooling system.

You could do it by simply dumping the coolant as well, but that gets cumbersome.

Hmm... seems horribly inefficient when compared to convective cooling... I wonder if some sort of a dummy load to suck out the most energy kinetically as possible would suffice to cool the secondary enough... of course the energy captured by the dummy load would still have to be dealt with...

Knock yourself out (or, more specifically, this).

It's a fun site overall, in spite of its geocities styling, so it's worth a look.

However, since by their nature radiators are difficult or impossible to armor, radiators will probably be the first thing shot off by hostile weapons fire. Then you have about thirty seconds to scram the ship's reactor before the engineering section turns into a sea of molten metal.

You should be able to radiate heat though space fine. That's how the heat from the sun gets to the planet from the sun. The heat from fission reactors has to go somewhere, hense minmatar ships have radiators, only they are unlike house "radiators" as they are designed to convect heat not radiate it. Technically anything dark, hot and has lots of surface area should radiate heat as IR fine, no matter if there is a vaccuum.

The're called "wingy bits"!

Assuming they are solar panels, what the **** else would they be sued for you imbecile?

That's why they're so big and frilly GÇö more surface to radiate from.

...stuff...

You need to reveal this useful secret to the aerospace industry as they've been building spacecraft with them useless radiators all this time. That thar's some serious weight saving idea you got.

modern spacesuits have cooling systems because body heat builds up forever in a vacuum.

there are zero particles in a vacuum, hence zero ways to radiate heat. (...).

In space? Through radiation.

heat is vibrating particles

they aren't part of a radiator system.

No. They have such systems because heat builds up faster than what it can be radiated. It's a volume vs surface thing: astronaut volume (body) generates heat faster than what the skin/suit surface can radiate it while preventing the astronaut from cooking if exposed to direct sunlight (wihtout insulation, heat would move quickly in both directions... inside too utside, but also outside to inside, and you don't want that under direct sunlight within Earth's orbit).

Otherwise radiation is proficent enough to keep ships uncomfortably cold unless they are warmed up. You could go and ask the crew from Apolllo XIII how fast was heat "bulding up" inside their powerless spaceship in the way back home. I'll give you a clue: without their heating systems, the moisture from their breath ended up freezing on the walls...

space is not a true vacuum........... why do people think space is a true vacuum....

a true vacuum would be devoid of matter... space is full of matter

Definition of a Vacuum

The're called "wingy bits"!

there are zero particles in a vacuum, hence zero ways to radiate heat. space does have some particles in it, but they are so few and far between that it would be meaningless. heat is vibrating particles. they aren't part of a radiator system. they are either solar panels, heat *gatherers* (absorbing sunlight), or just there for the same reason everything in EVE looks the way it does - because an artist thought they looked cool.

Finally if the 'sail thingies' are not radiators, then if the current modifications to the Standard Model of the Universe are correct then Dark Matter & Dark Energy could provide the weird particles or energies required for reactor or warp drive to work, in that case the 'sail thingies' would absorb them for the warp drive or reactor!

Uh...solar wind FTW.

From Wikipedia:

'The solar wind is a stream of charged particles ejected from the upper atmosphere of the Sun.'

And the crew of the space shuttle, on some of its early missions, noted that the shuttle's heat-shield absorbed heat form the sun and expanded, producing an audible 'roaring' noise within the spacecraft.

Besides, if there was no way for heat to radiate in a vacuum, Earth would be a block of ice.

space does have some particles in it, but they are so few and far between that it would be meaningless.

Uh, did you read what you quoted?



the solar wind is so unbelievably sparse that you'd have to be silly to factor it in here. do you have any idea how large a solar sail needs to be to pull a tiny little mass, like, say, 1kg?

and we are talking about radiators. a radiator will basically not function in a vacuum, simple as. there simply isn't nearly enough matter in space for thermal energy to ever transfer in significant amounts. if you wanted to cool off in space, you would have to use very different methods, such as turning that thermal energy intro electromagnetic radiation.

also, please read what you quoted again. heat is *not* being directly transferred from the sun to space to the earth. it is radiation striking the earth and energizing its particles. the space between the earth and sun is still pretty much 0-¦K.

here, go buy a thermos. put scalding hot food into it, seal it, and let it sit there for a few hours. open it up later. you just witnessed how any object encapsulated in a vacuum (almost encapsulated, in this case) will not cool off. If a "radiator in space" worked, then the thermos would cool off just as quickly as if it were a metal jug.

I'm picking up a lot of radiation...
they're operating without core
containment. Well, that's feng kuang de,
that's suicide...

Proof positive Minmatar are Reavers

No. Heat is a form of energy. In matter, it generally manifests in the form vibration GÇö kinetic energy, if you want to simplify it.

You mean liquid vacuum huh? Dont forget that there is no usual physics in New Eden Universe.
Besides there is lot of objects in EVE space that you cannot call "usual vacuum' like gas clouds, for example.

I don't know almost anything about EVE lore, but if what people are saying about Minmatar using nuclear reactors is true, then the radiator idea still doesn't make sense. Yes radiators can radiate heat without convection, but on something like the ISS or the Apollo missions. The ISS does not have to radiate heat from a nuclear reaction. Radiation is so inefficient there is no way it would be able to effectively cool a nuclear reaction.

o_o Kind of scary how many people don't understand how heat is transferred though. Either way I will just pretend they are speed fins and all the Minmatar pilots are teenagers.
