This might slow down wireless intruders, but not stop them...... Now if we where to come up with a package that makes a computer pretend it was an open relay we would be set.
Imagine a BeoWolf cluster of these;-) A spammer finds what he thinks is a open relay and all it does is send his junk to/dev/null.

Um, put a polarizing filter on the monitor, add a simple 90 degress polarized light source to the front of the monitor (translucent sheet) put on your polarized glasses and you are set.

The trick here is if you need more payload you strap on extra boosters.
That's why lockmartin has been calling it 'dial a booster'
Atlas V XXX First X, payload fairing Diameter (4 or 5 meters) Second X, number of solid strap ons (max 5) Third X, number of LOX/LH2 engines in the second stage (1 for GTO insertion, 2 for LEO insertion). The second LOX/LH2 actually hurts GTO insertion performance (extra unneeded weight), but the extra thrust is needed for LEO insertion.
Of course the Atlas V heavy does not quite fit into this, two strap on common core boosters (Saturn 1B concept). The only customer will probally be the DOD. I don't think they ever sold a single Titan III/IV to a comercial customer... no need for the extra capacity.
And to make sure that the system is robust, two manufactures, LockMartin (Atlas V), Boeing (Delta IV). Both who can sell excess capacity to the comercial launch industry (higher volume helps keep the costs down). Remember this a military vehicle that they will allow civilian users to use to keep DOD's costs down.
As far as currently operational systems go, maybe yes...
They are talking about the Atlas V Heavy, not the Atlas V 4xx and 5xx configuration. The first stage is three Common Core boosters strapped together (ie three Atlas 501's strapped together, a two engine centuar upper stage and a 5 meter dia. payload shroud). The Heavy has not yet flown, but should have the same abilities as the Delta IV heavy which can do 23,000 Kg To LEO and 13,000 Kg to GTO.
This is more than the Proton, ~3000 Kg to GTO This is more than the Ariane V, 6800 Kg to GTO Similar to the shuttle, 24400 Kg to LEO
btw. The Delta IV heavy is scedualed to fly before the Atlas V heavy.
The SRB (solid rocket boosters) are recovered and re-used in most cases... There were a few that sunk early in the program, and the challenger units where destroyed by range safety.
The ET (external tank), big orange external gas (H2) and oxidizer tank (O2) is not recovered. This is a big waste.
I've been in the situation, After an incedent it becomes the flavor of the week until someone whines that it's taking up some of there precious time, then the responsibility gets dumped on you again and everyone stops backing up yet again...
These days you can fit the necessary DC to DC stepup converter inside a package the size of a match box.
Hamamatsu makes several Photo Multiplier and Photon Counting Tubes that run off of 5v and internally generate up to 1500 volts. The voltage is clean enough to run a photo counter. The step up converter is small enough to be hidden in the tubes socket... That's what Hamamatsu does.
Water Cooled Tubes are in many high power modern RF transmitters... I have yet to see a solid state high power AM transmitter. Semiconductors can just not take the power load.
Water cooled tubes are designed and built to be water cooled. When I did college radio we had an Old Harris transmitter that use to melt the tubes on us (as in the tube would come out as a glob of glass). We replaced it with a prototype first generation Harris Solid State FM transmitter... and was in 1995.
Check out Harris for more information on high end RF systems. Hmmm... looks like they do have solid state high power AM transmitters now... amazing
Though price is nice, it is not will initially sell this device...
If it has a smaller foot print and is more efficent than other direct cooling technologies, it will sell.
Trust me, If I could use this to cool a CCD chip down to LN temperatures without the use of a water chiller or LN dewar I would be willing to pay for it.
>It's piratanical trolls like you that killed Atari the first time!
??? so my debate on buying the product or investing in the company is evil because I pay for software and invest in that software model, maybe you should re-read what I stated.
Atari is getting royalties of of this, and it was the attempt to live off of the 2600 and not investing in new console technology that killed them the first time...
btw. at $20 I will be buying one... as for stock, I do feel this could be a sleeper, but need to research it first.
The software model I use is, you buy our instrument, it acts as your software key, so we give you the latest software (of course our hardware 'keys' are between $5K and $200K depending on model).
This is news? It is a well know effect... The real trick is picking background noise out of your signal (hint : it is very trivial).
Here is a trick for you kiddies...
The US power grid is 60 cycles, That means Fluorescence lights turn on and off 120 times a second... That means filament lights have a detectable 120 hz intensity ripple... 60 cycles gives you a wavelength about the size of north America... So the whole US turns on and off 120 times a second
In Europe it is 50 cycles...
What does this mean from space?
The whole power grid turns on and off between 120 and 100 times a second (depending which frequency it uses)
Watching the phase of a single light compared to the rest of the grid tells you if that part of the grid has a large inductive load (big motors), resistive load (big computers), or capacitive load (big particle accelerator) on it.
Watching a light that doesn't flicker in sync with the local grid tells you it is on internal generator power (big target).
And you ask how do we know the facility is a viable target?
Lesson : if you want to avoid being noticed stay on the grid and stay in phase. Otherwise big brother will find you and send your coordinates to a circling B-52:-)

No, it was a homing beacon because the radar for tracking it has not been built yet... The homing beacon was an attempt to simulate the radar... I am curious as to why they think this sort of intercept will work... I think boost phase and and reentry phase intercepts would be more effective...

Atlas V (and Delta 4) was funded through the DOD's eelv program to give it assured access to space.
If you check nasawatch they have an article about the military taking the X-34 bird back from NASA.
