Re: Could we harness energy from black holes? Obviously we cannot harness energy from black holes because there is no such thing as a black hole.
There are, however, such things as plasmoids. Not only have they been produced in the laboratory (unlike black holes or dark matter, both of which have never been detected or produced in any experiment, because they don’t exist) they have been detected at the centre of galaxies, where they have been mistaken for black holes by observers blind to the fact that ours is a plasma universe governed by electrodynamic effects.
Plasmoids might be used as a way to directly produce energy. The plasma focus device has been touted as a device that could lead to practical nuclear fusion, but it still has some obstacles to overcome.
Re: Could we harness energy from black holes? Not to be starting an arguement, as I have no knowlege to defend either side, but that article suggests a very hard way to do this.
It says make and break magnetic field lines very close to the event horizon - which is the theoretical point of no return, where you are now at the one way point, getting sucked in.
Still, as our research folks work on this, they might come up with some way to get way, way out there and test it. It would certainly be great if they can prove it works. Among other things, it would mean our space exploration capabilities got really advanced - or we couldn't test it.
Re: Could we harness energy from black holes? The way is even harder than the article supposes, because it just assumes that there are black holes. So it’s like saying we could solve world hunger by having Santa work two days a year, and on the second day he flies around the world delivering food parcels. Rather than spending time figuring out how long he would take, based on calculations of the time it takes to deliver toys to all good girls and boys the world over, we should instead dismiss the entire idea as a fantasy built around a non-existent entity.
Re: Could we harness energy from black holes? Well, some much more research needs to be done, with far better telescopes. The idea that matters most is whether we can leapfrog technologically into space habitation in our own solar system, with a pay off? Now, one has to asks is what motivates leaders to go for far ranging capabilities? Example, we didn't try to do a Mars run the 80's.
The far universe such as purported black holes etc, will, as of this day, be a far off consideration. It's a mind game, and outside of astronomy will have zero impact on our lives.
