Are black holes a potential source of infinite energy, supposing

>>9167488
No, they actually release very little power. Basically the worst power source you could think of besides nothing.

>>9167520
Well I can only assume how much thermal energy is trapped in the singularity but I don't see any way possible of harnessing it

>>9167520
>>9167488
black hole's radiation (hawkings radiation) is inversly proportional to it's size, meaning tiny black holes behave like powerfull bombs turniing their mass into energy

so it should be theoretically possible to have small black hole giving strong radiation while you keep feeding it mass to keep it at constant size
this would be most efficient way of turning mass directly into energy

But you wouldn't really want to have a black hole anywhere near your local system.

>>9167611
None, the bigger black holes are the lower "temperature" they have, all the black holes in the universe are probably at like 1K

>impliying this shit does even exists

>>9167488
you need an equally large big black rod to harvest the said energy.

>>9167761
A BBR I see.

Isn't there way to continuously harness the black hole's gravitational energy by converting it into mechanical energy? I figured that would be much more efficient than harvesting heat energy, which would be more sensible for solar objects.

Not infinite energy, but it's theoretically possible to extract energy from a rotating black hole

What the fuck is the eye of harmony?
Get the fuck out of my /sci/ you brainlet

>>9167631
But that's wrong, the amount of hawking radiation is actually very small in human terms. Like it could power one small light.

>>9167770
Gravitational "energy" is like the opposite of energy.

>>9167982
a black hole with the mass of 1E-5 earths,
its temperature would be about 2055K

>>9167631
If hawkings radiation exist then we're pretty much a simulated universe, confirmed 100%.

infinite no, massively long lasting yes. It should be possible to tap both their rotational energy and hawking radiation to generate power, problem being that the rate of radiation emission is inverse to size. So that leaves you with trying to produce tiny ones and feeding them, or waiting for the universe to cool enough to come much closer to the landauer limit.

Oh really? Why's that?

I wonder how much boost will gravity assist around one of those give you coupled with some nice oberth burn with nukes.

What if you had a really long rope and wound one end around a crank and threw the other end into the black hole?

>>9167770

Theoretically yes. And would be 100x more efficient to do it this way versus fusion reactions. The SciShow channel on youtube did a good job explaining how it could get made. Basically, they suggested constructing a dyson swarm to collect the sun's energy and concentrate photons on to a single point. Since photons bend spacetime, enough photons in one spot could generate a black hole. At this point, you could feed the black hole mass and it would do a 100% energy conversion. Of course, they said you would need 10% of the suns power to do it, and Mecury would be harvested to make the dyson swarm, but it was all theoretically possible even if it was on an unimaginable scale.

So if objects travel in elliptical orbits, and suppose that part of the orbit passes through the event horizon, where did the energy to leave the event horizon go?

fuck off brainlets. A a small black hole like a kugelblitz releases immense amounts of radiation.

Not really. not sustainable at the very least. if anything the rotational energy would be a sma source of low yeild.
>>9170114
thats impossible. the event horizon is the point where nothing can escape, even when moving at the speed of light. It's like saying suppose a quarter circles the drain and part of its circle goes down the drain and then back out.

There are no such thing as black holes.
Think about for a second how fucking stupid it is to think that space can shrink and contort to a null point.

its always a joy to hear the thoughts of brilliant scientist that are experts in their field

from two black holes spinning around each other

>>9167488
you'd have to decrease the potential for virtual particles to co-annihilate by choosing a polarity in a field around said black hole, generating a tendency for said particles of opposite charge to escape the vicinity, thereby reducing the mass of a black hole over time.

possible? yes. infinite? no. functionally limitless? possibly.

>>9167770
There is tidal energy, like tidal heating but ultimately you'd fall into the blackhole if you got anywhere close enough to extract energy from it.
