Granted, I'm just another /.-er who never RTFAs, but I do have some experience w/ FO comms and free-air transmitters (of one wavelength or another).

So consider: the channeling lasers may disperse, but they carry no information beyond the existence of the channel and possibly the source and destination. The transmitted data packets do not disperse, so what you've got is the equivalent of a phased-array transmitter with zero sidelobes.

A few years back, before Obama, one of my black friends said when we have the first black president they are gonna paint the White House black, and call it the "Black House."

In fact, the political comedian Dick Gregory said that about his own satirical run for president back around 1968 or so. When I'm president (c'mon, you guys gotta start campaigning for me!), I think I'll do the exterior in Jackson Pollock.

It's kinda like cable tv: 500 channels, of which 450 are QVC, 40 are rerun channels, and 10 are worth watching.

Similarly, plus its "affiliates" claim 100k books, but rather a lot of them are of extremely limited interest to anyone other than historians.

Amazon has roughly 33 million listings; even allowing for overlap between kindle, paperback, and hardcover (and audio), 600k is a rather small fraction of what's out there.

Meanwhile,today, if you can afford a $90,000 car, I doubt there are any real impediments to your making that purchase.

That's all very nice and snarky, but Tesla's got a Model E in design with a target sticker price of around $30k US. Wouldn't it be nice to fix the problem now, so in a couple years we don't have to order our Tesla-E via Amazon Prime?

The military application is that it is rumoured to be able to detect stealth aircraft.

No rumor that. Dunno about cell towers, but it was shown pretty conclusively in the '90s that the "hole in the sky" caused when a stealth aircraft blocks FM radio signals can be seen. Depends of course on having a good FM sensor and a solid transmitter or two in the area.

I don't see a problem showing a device is working as intended. If it can prevent even one bomb from going on a plane it's well worth it.
I don't see why people are getting bent out of shape about this. Take a chill pill people.

Dunno why I'm responding to a subhuman troll, but hey it's Monday, so:

First of all, it won't prevent any bombs from being brought onboard. How difficult do you think it is to show a working laptop which happens to have 500g of C4 wedged inside?
Second, it's an absurd abuse of reality, since as everyone and his brother already said, any device w/ dead battery -- or heaven forbid, some toy that only runs on AC and you didn't bring the adapter-- gets tagged as "dangerous terrorist thingie."
Third, it'll be cheaper to pay $10 million per person injured, let alone killed, by your fictional device-bomb than the direct and indirect cost of this screening program.

Finally, it'll take approximately negative 5 seconds for any potential bomber (of which there aren't any in the first place) to use some other gizmo to carry a bomb. Like a fake tin of sardines. Ooops, apologies to everyone who was going to bring a snack on board.

Aren't you glad you're not getting all the government you pay for now?
