Black energy of the future.

[ronthepon]

I recently had come across mentions of hawking radiation.

 

Then, I thought if this could be useful as a source of energy in the distant future.

 

We could consider collecting small-sized black holes in the future and attempt to harness energy from them.

 

Now how would we do all that? Put your hypothetical thinking caps on, people.

 

For a start, there is a question of how to move black holes from here to there.

[arkain101]

well its possible that they would emmit powerful radiation when matter interacted with the outside layer.

 

I think we need more than a thinking cap on this one. We need an alien implant.

 

(btw, what is up with the trophy beside names?)

[ronthepon]

The trophy is for arcade champions.

 

Ok, for getting the black hole to the correct location we can use some gravity based tow-object.

 

As the black hole won't be as massive as the earth (probably around the mass of several big mountains), we can do so.

[sebbysteiny]

Ignoring the practical impossibility of creating a black hole of any decent mass smaller than a super massive star, wouldn't it be simpler just to create nuclear fusion?

 

A black hole just converts all its mass into energy, but why worry about that when there are already more feasable options.

 

However, if you really want it to work, then why worry about transportation at all? simply find a very big black hole, put satalites in orbit around it so that they can reflect the energy back to earth, where another satalite concentrates the energy on heating water and driving a turbine.

[ronthepon]

An alternative, sebbysteiny, not a primary technique.

 

Just like petrol once looked so much better than wood as a fuel.

 

In any case, the sattelite option is feasible for the bigger black holes. Unfortunately bigger black holes are not as useful, because they emit at a lower rate.

Further, we would not prefer to build a setup for each new black hole.

[arkain101]

I'd like to see evidence of 'small' black holes before thinking too much on this.

[UncleAl]

We could consider collecting small-sized black holes

How much does a "small-sized" back hole mass? How do you grab it? AFter 14.7 billion years, all small black holes have decayed. Remaining black holes are cooler than the cosmic background and accrete not decay.

[sebbysteiny]

A 'small' black hole would take more energy to make than you would get back.

[Jay-qu]

We do seem black balled on this idea, if you could find one they are to far away to bring closer, they would also be to far to bother transmitting the energy back at a mere velocity of c, and if we tried to make one here it would take a lot of energy to make - whether that is more than we get out I cant be sure.

[ronthepon]

So all the black holes present now merely absorb energy and get mass?

 

What after the cosmic background becomes cooler?

 

And considering that black holes of the mass of 30-50 solar masses can form, we can hope for them to lose energy overtime till then.

[Tim_Lou]

if we are to gather energy from hawking radiaton why not just use solar power?

[ronthepon]

Ofcourse! If we colonise beyond the solar system, making our own artificial energy gathering planets will be equally or even more useful...
