hey guys. you don't need stars to create energy. see those 2 planets that orbit each other? gravity deforms them, and the friction results in heat.

suck it noobs?

Now if only there was some way to harness heat to produce work without assraping thermodynamics.

wut?

never new energy could be create. This is new to me.

Maybe some type of hypothetical "heat engine" might work?

>> No.1956393

>>1956388
Yes if only we had a heat gradient instead of all this random heat everywhere.

>> No.1956437

>>1956393
if there's no gradient than is there even heat at all? the term heat applies only to an energy transfer.

>> No.1956449

>>1956437
A heat gradient is when a substance is at varying temperatures and a heat exchange occurs.

If something is just heating up constantly there is no heat gradient.

>> No.1956458

>>1956437
No, heat is the internal kinetic energy of a substance. There doesn't need to be a gradient. There doesn't even need to be a measurable, well-defined temperature.

>> No.1956464

>>1956449

That's a thermal gradient, there's no such thing as a Heat gradient

>> No.1956470

>>1956458
No you're thinking of enthalpy, different thing that. except under constant volume conditions at which point enthalpy is just heat.

>> No.1956472

>>1956470
wait, no fuck that should be constant pressure conditions.

Also, good luck warming up these -273°C to bearable levels with your friction.
