Axil,
I just looked at the first paper
http://arxiv.org/pdf/1202.2539.pdf and can see why you said that no useful
energy could be extracted from the "time crystal" because it is in it's lowest
energy state but just as they speculate The crystal is only half the equation
like a windmill without a rotor you need gas [field or particle] and relative
motion to the time crystal lattice. "the apparent non-conservation is in
reality a transfer to the background" IOW ZPE can be extracted -not a violation
of the 2nd law but rather a practical method to implement an HUP trap.

2. It is interesting to speculate that a (considerably) more elaborate
quantum-mechanical system, whose states could be interpreted as collections of
qubits, might be engineered to traverse, in its ground configuration, a
programmed landscape of structured states in Hilbert space over time.
3. In general, fields or particles in the presence of a time crystal background
will be subject to energy-changing processes, analogous to momentum-changing
Umklapp processes of ordinary crystals. In either case the apparent
non-conservation is in reality a transfer to the background. In our earlier
model, O(1/N) corrections to the background motion arise.

I posit their math can be related to the Casimir formula where these time
dilating repeating structures accumulate their force in a geometrically
organized and segregated manner responsible for equal and opposite values of
delta time / spatial volume. [very dilated tiny cavities or much larger volumes
of space parallel to the exterior surfaces of the cavity with only tiny
dilation]. The books are balanced through segregation and it requires " fields
or particles moving through this time crystal background being subject to
energy-changing processes" IOW changes in the bond state of gas particles
traversing a programmed landscape [Casimir tapestry] OR the Haisch and Moddel
method of Lamb pinch.
The paper adds support to the Naudts paper on relativistic hydrogen inside a
lattice, the claims of radioactive half lives of gas being modified in a
lattice, my own relativistic interpretation of Casimir effect where virtual
particles are displaced along the time axis and locally remain unaware the
plates are too close for their full wavelength to fit between.

It sounds like the title of a bad fantasy movie - time crystals - but it could
be the next big thing in theoretical physics which might be worth the time and
pain to rap one's mind around this new weird subject.
Those who are interested in zero point energy should expand their interest to
include time crystals as a motive principle in the weird and unexplained...
ideas possibly related to the realm of perpetual motion machines.
In two new papers, Nobel Prize-winning physicist Frank Wilczek lays out the
mathematics of how an object moving in its lowest zero point energy state could
experience a sort of structure in time. Such a "time crystal" would be the
temporal equivalent of an everyday crystal, in which atoms occupy positions
that repeat periodically in space.
The work, done partly with physicist Alfred Shapere of the University of
Kentucky, appeared in part on February 12 in arXiv.org.
"We don't know whether such things do exist in nature, but the surprise is that
they can exist," says Maulik Parikh, a physicist at Arizona State University in
Tempe.
Like Murphy Law states: "If it can happen, it will happen,".
Like any new idea ,scientists don't know how important time crystals may turn
out to be, or whether they have any practical application at all. But Wilczek,
of MIT, says the concept reminds him of the excitement he felt when he helped
describe a new class of fundamental particles, called anyons, in the early
1980s. "I had very much the same kind of feeling as I'm having here," he says,
"that I had a found a new logical possibility for how matter might behave that
opened up a new world with many possible directions."
Wilczek dreamed up time crystals after teaching a class about classifying
crystals in three dimensions and wondering why that structure couldn't extend
to the fourth dimension - time.
To visualize a time crystal, think of Earth looping back to its same location
in space every 365ΒΌ days; the planet repeats itself periodically as it moves
through time. But a true time crystal is made not of a planet but of an object
in its lowest energy state affected by zero point energy, like an electron
stripped of all possible energy; zero point matter is you please.
This object could endlessly loop in time, just as electrons in a superconductor
could theoretically flow through space for all eternity. "It's doing what it
wants to do, and what it wants to do is move," says Wilczek.
In a sense the time crystal would be a perpetual motion machine: If scientists
could build one in a lab, it would run forever. Yet it wouldn't violate the
second law of thermodynamics because the crystal would be in its lowest energy
state; no useful energy could be extracted from it.
Wilczek is already dreaming of extending the time crystal concept into
imaginary time, a theoretical concept of the fourth dimension that runs in a
different direction than the one people experience.
"I don't know if this will be of lasting value at all," he says, "but I'm
having fun."
And like frank, all we want to do here is have some fun.
