no it can't its not possible
I know because I am a Physics teacher.

Vaccum is not energy, but energy can be harvested, and a variety of different methods exist such as;
1. solar power
2.Thermoelectricity
3. Piezoelectricity
4.Ocean tides.
5.Geothermal .
Did you know that we can harvest the energy expended from footsteps and the vibrations from trains?
There's been a surge of interest over the past 10 years, driven by the search for battery-free techniques for powering wireless sensor networks, laptops and mobile phones.
The concept was pioneered by the military sector, largely bankrolled by the DARPA in the United States (Defense Advanced Research Projects Agency). http://news.bbc.co.uk/1/hi/magazine/5009358.stm

Vacuum itself is not an energy. A vacuum is created by expending energy. More energy is consumed in creating the vacuum than is returned by allowing matter to rush back in to the vacuum.
Energy from nature is created all of the time. Solar and wind energy are two examples of 'free' energy. Two others are tidal energy and ocean thermal energy. Even what many people think of as the 'dirty' energies are from nature. Things like oil, coal and nuclear power are all natural.

All our energy comes from nature.
Vacuum energy probably can't be harvested, since it is supposed to be the lowest-energy state of the vacuum. This may not be the case, however. It is possible our vacuum is a "false vacuum" and that energy could be extracted from it. This is just speculation.

While energy (photos) can pass through a vacuum, vacuum itself is not energy and cannot be harvested.

"loose means" is often utilized to a crackpot layout for a self-powered generator. in the context of your question i anticipate you recommend means with 0 value of manufacturing. the difficulty is that the graphene itself, alongside with the different areas required in manufacturing of means on a practical scale, is expensive to produce and look after. The agencies putting up the money to try this might assume a return and so the "loose means" turns right into a commodity bought to the utmost bidder with all people in contact desiring a slice of the salary. As with hydro-electricity, the promise of inexpensive means has been overtaken by utilising advertisement greed.

May be...Everything is possible.
If vaccum can have energy, someday we may be able to trap it definately.
Till then, keep looking...

If you can find a way around the First and Second Laws of Thermodynamics, then yes.

Do you mean zero point energy? Then no by definition.

Yes, and I'm thinking of non-conventional types of energy:solar, eolian, hydro...
