Yes, and I must say my eyebrows rose ever so slightly over the dimensions inherent in their concept with regards to the atmospheric "Dark Sky
Station". Omnious name, by the way. 3 km across, thats no small thing to have up there.
But, of course, the best would be a craft that could do the whole Earth to Orbit transition without any need for a waystation.
It seems that graphene has some interesting derivatives, and I bet there are even more exotic materials also tucked away. So if you are basically
weightless, and fuel consumption is mainly for station keeping and to counteract weather, I guess you would not need to refuel that often. And, if the
power is indeed nuclear, well... then you could just stay up there, as a well hidden base of operations for all sorts of things. And if you could hide
it in space?
I find it a little interesting that "oily black" seems to pop up in quite a few of the descriptions I have read of the smaller triangles. I don't know
where optical stealth has gotten to, but I read about this canadian firm that claimed to have it nailed down and even claimed to have demonstrated it
for the US millitary, but then the project was cancelled. Could be that it didn't work well enough, or even at all, but it could also be that it was
never cancelled. Or maybe they had something better already.
The Canadian Company I think you are talking about is HyperStealth
of Maple Ridge, British Columbia, Canada (about 50 km east of
Vancouver, Canada) which was of course PURPORTING to use
"Negative Refractive Index MetaMaterials" which SUPPOSEDLY
traps and bends light around a stealthed object or person.
I DO HAVE an issue with this company because
I ABSOLUTELY KNOW on a PERSONAL BASIS
just how hard and EXPENSIVE it is to make
even SMALL Negative Refractive Index
MetaMaterial squares because you
REALLY DO NEED CMOS chip-making
or Nano-Imprinting technology to
be able to make the micro-etches
necessary on a suitable base material.
That is VERY VERY EXPENSIVE!
It's actually FAR EASIER to use cloth-based
digital-ink technology which are microspheres
bonded to a cloth substrate that contain a
liquid crystal that changes orientation
and/or phase to create a reflective
surface of the desired colour depending
upon the application of an electrical current!
A computer and a camera could obtain
and digitize the surrounding environment
and map a particular incoming optical stream
to the opposite side mapping and modifying the
incoming pixels to fit the EXPECTED and/OR
CALCULATED optical pathways. This is an
ACTIVE visual stealth system since you
need some on-person/on-vehicle
computers and cameras to
map incoming light rays to
the opposite side of the
item being stealthed.
Digital ink is CHEAP
and you can get it in
COLOUR as many e-Book readers
contain the technology which is
a LOT CHEAPER than an active matrix
smartphone-type OLED or LCD/LED screen.
Anotehr method is to use tiny and very
flexible micro-optical fibres to PASSIVELY
trap incoming light rays and bend them
AROUND an object. By putting micro-lenses
at the endcaps of embedded optic fibres
(usually plastic multi-mode fibre) you
basically only need about 100 fibres
per square inch to reasonably
provide a visual stealth from
between two to 100 meters away.
The denser the fibre array
the better the stealth
and being PASSIVE, no other
onboard power or cameras
are needed BUT it is physically
heavy becuase of the number
of micro-fibres needed to be
bonded to hard or soft substrates
which will cover the stealthed
item or person.
AND FINALLY you could use micro-video-screens
arranged in squares 1 to 2 inches in size that have
BOTH MICRO-CAMERAS (i.e. CMOS chips with
Sony HyperHAD-like microlenses) and OLED pixels
to capture incoming video transmit to another
software/hardware identifiable square and emit
light at the opposite side. The communications
between the squares would be high-bandwidth
but low-power nearfield mesh-network communications
powered by either RF or inductance.
THAT is how I would do the Visual Stealthing
ON-THE-CHEAP because using a TRUE metamaterial
is just too darn expensive today !!!!
