Futuristic Question
Forums › General Discussion › Futuristic Question-
Anyone think it's possible to harness "vacuum energy". I just finished reading all of the Space Odysee books and at one point that's what they talked briefly about. Powering this futuristic society. That sounds like it might work... Maybe. I'm no engineer, but it still sounded interesting. Ehh. I wonder if anyone would find this interesting here. Forums are sorta dull these last few days.

Why did you stop doing roasts? Just wondering.

Who knows, science fiction often leads to the science fact. One of my favorite books starts with a boy riding his horse in the desert when the phone rings and he answers it. This book was written back in the 1950's by Robert A Heinlein. These days it is standard that we can answer calls anywhere but back then that would have seemed impossible.

Interesting subject. The concept of free energy has always been something that has been pursued in some form or another. Unlikely feasible, but a noble idea.
-
That's dangerous thinking Jeff. Shifting the energy levels of cosmic vaccums could very well destroy our planet.
-
And here's why I say that...
In many situations, the vacuum state can be defined to have zero energy, although the actual situation is considerably more subtle. The vacuum state is associated with a zero-point energy, and this zero-point energy has measurable effects. In the laboratory, it may be detected as the Casimir effect. In physical cosmology, the energy of the cosmological vacuum appears as the cosmological constant. In fact, the energy of a cubic centimeter of empty space has been calculated figuratively to be one trillionth of an erg.An outstanding requirement imposed on a potential Theory of Everything is that the energy of the quantum vacuum state must explain the physically observed cosmological constant.
-
However extracting that energy could theoretically lead to a false vacuum. In quantum field theory, a false vacuum is a metastable sector of space that appears to be a perturbative vacuum, but is unstable due to instanton effects that may tunnel to a lower energy state. This tunneling can be caused by quantum fluctuations or the creation of high-energy particles. Simply put, the false vacuum is a local minimum, but not the lowest energy state, even though it may remain stable for some time. This is analogous to metastability for first-order phase transitions.
Meaning The possibility of a Chaotic Inflation theory suggests that the universe may be in either a false vacuum or a true vacuum state. If a bubble of lower-energy vacuum were nucleated, it would expand, approaching at nearly the speed of light and destroying the Earth instantaneously, without any forewarning. Thus, this vacuum metastability event is a theoretical possible doomsday event.
-
So, if we found out how to harness it somehow, it would be a sign that *insert doomsday material you just stated* is upon us? Or would that actually cause the whole scenario to play out? And I need to re-read that a couple of times haha. And raiko, I just got bored of it.
-
And I'm not understand fully the false vacuum thing. I can't wrap my mind around what it is, exactly.

I was thinking this morning about creating energy in space.
What if you set a turbine turning in space.
There would be no air resistance to slow it down. And no noise to sap the kinetic energy. -

I think new forms of energy will come around. It will no longer be gasoline or electricity, but something better.

No air resistance. No noise.
In theory, once you push it, it should keep turning forever as there is nothing to slow it down. -

I doubt it! It was late 17th century maybe early 18th century discovery. -

If its powering something then the energy transfer would be energy lost to the turbine. It would slow down and stop.
Also if using solar wind, what anchors the turbine in place? Solar wind would push it away like it was a solar sail -
However. Thinking about it, if you set up two sails, one within the other. Set up like a turbine so the solar push turned one clockwise and the other widdershins. With the rotation point between inner and outer sails set up like an electric motor/generator. Then you get the basis for a spaceship propulsion and power unit.

Vacuums don't actually exist. Even in what we call "the vacuum of space" elementary particles are always being created. Plus there are about 4 atoms of hydrogen per cubic meter in space

Think of it like this: A false vacuum is a relative vacuum. It is lower pressure than another area, but not a perfect vacuum. And like Conn-man said, perfect vacuums don't exist in nature; vacuums do exist, though, even if they aren't perfect. Even a vacuum cleaner creates a slight vacuum. I'm not a theoretical physicist, just a nuclear physicist, but I did a lot of work with vacuums and their theory. Also, regarding the perpetual motion of turbines in space, there are other turbine losses that exist regardless of the state of vacuum, and therefore, a turbine in a perfect vacuum will stop if left alone because of these vacuum independent turbine losses.And I'm not understand fully the false vacuum thing. I can't wrap my mind around what it is, exactly.
