Why free energy is not possible? The collision of virtual particles should generate gamma ray

[gabl8a89]

Im not expertise on this field,

however I do concern about the sustainability on our earth.

and finding a renewable energy base on quantum physics

seems inspire me alot.

 

I know there is a new form of energy call vacuum energy

and it exist everywhere, everytime, but why we can't exploit this energy?

 

according to E=mc2, when two virtual particles collide,

they should just like matter-antimatter collide, which

ends up as gammaway.

 

According wikipedia,

"the vacuum energy in a cubic centimeter of free space has been estimated to be 10⁻¹⁵Joules.^"

http://en.wikipedia.org/wiki/Vacuum_energy

 

which mean if we can build something big enough,

such as a device

1000000000000000 x 1000000000000000 x 1000000000000000 big,

we should able to extract 1 J of energy in the given time.

 

I know my idea sounds stupid to some of you,

but assume we are now able to build this hypothetical device

is that really going to extract 1 J in every given time

Maybe its some kind of energy, but is it usable in any way? I mean we can't really even use gravitational waves themselves unless we have substances to cause friction, like a waterfall, sand paper, etc. Also, it seems incredibly inefficient anyway. Unless the units your using is angstroms, 1000000000000000 of any unit to get like 1 joule isn't that efficient.

I know its not efficient

but the point of this questions is to discover

whether extracting energy in vacuum is possible.

 

I dont know much about quantum physics seriously,

but i know when matter and anti-matter collide,

they will transform into a beam of intense gamma way.

 

If the same theory apply to the vacuum fluctuation,

we should able to obtain energy from the virtual

particle annihilation.

 

Many people say

extracting vacuum energy is not possible because

vacuum is the lowest state of energy, therefore extracting

energy from the lowest state is not possible.

 

but vacuum itself its not the lowest state!

because vacuum itself has vacuum fluctuation,

which mean in quantum scale, some vacuum space contain more energy

than other vacuum space.

 

so, why extracting vacuum energy is still not possible?

You can't extract it. You certainly can't extract it using a system similar to how you suggest. The particle pairs are only in existance for a tiny tiny time (prescribed by the uncertainty principle), it would take more energy to make them into real particles and then annihilate something with the antimatter and capture that energy than you would ever extract from the system.

so, virtual participle collide wont generate gamma ray?

A recent arxiv paper seems to indicate that we may be able to extract quite a bit of power from vacuum energy via piezoelectrics and the casimir force.

Well wait, how did scientists figure out there was particles created out of the vacuum of space unless they did have real effects? Didn't they have two plates and they were forced apart because of the energy in the vacuum caused by virtual particles?

One of the virtual particles has positive energy and one has negative energy. So when they collide, no energy (such as gamma rays) is produced.
