Tiny, Morphing, Electricity-Stealing Spy Planes Developed 163
tkohler writes "The Air Force Research Lab is developing an Electric Motor-powered Micro Air Vehicle (MAV) that can 'harvest' energy when needed by attaching itself to a power line. It can also temporarily change its shape to look more like innocuous piece of trash hanging from the cable. For domestic spying, maybe it will morph into a pair of sneakers?"

Actually, it's the drug users that throw the shoes up there. Drug pushers are for some reason (a mystery to medical science) compulsively driven to powerlines with shoes hanging from them. Obviously this is seen as a big problem for the drug dealing community, which is trying to enter the 21st century, leveraging such fast-paced technologies as 'two-way pagers' and 'cellular telephones'. They find themselves involuntarily skulking around power lines in every sort of weather, knowing full well they could be successful drug deals in the back of the local chuck-e-cheese, but find themselves incapable of breaking the spell of such a powerful lure.
Or maybe it's some sort of urban legend or something, and it's just, like, kids with nothing better to do throwing up some shoes. Dunno.

There was a tree near a fraternity at my college that always had a bunch of shoes in it. The rumor was that once someone had sex with a girl they'd steal her shoes and throw them up there. There were a lot of mens shoes in that tree, so I doubt the truth of that rumor as well.

Why do they assume the UAV would be conductive? Wouldn't your best bet for tapping energy off power lines be to simply use induction? You don't even need to land on the lines themselves; a fluorescent tube light will light up at yards from the power line.

Not quite. Hold one end of the tube, point the other end at the line. Needs to be one of the higher voltage ones cos experience shows that 11kV doesn't cut it (although it might work if the lines were really close to the ground, depends on the electrostatic field in Volts per meter). The tube will light but not that brightly so you'll have to do it at night for it to be visible. Ever see this photo? [cpluv.com]

Sure, but you need a difference in potential for that to happen, and you won't get one unless the UAV creates a bridge between the line and the ground. Birds have been partying on power lines for about a century now, so it's pretty silly to assume there's going to be massive disasters caused by UAV's emulating them.

I wish you had given some examples here, Just because I am curious what technologies you think far outstrip what's available to "regular folks." It's not as though you can go to Wal-Mart and pick up an APIC and a li-ion box. But then again until a few weeks ago you could buy uranium on Amazon.

Using electrostatic field gradient (Score:5, Informative)
Cute idea. What they're trying to do, it seems, is mooch a little power from the electrostatic field gradient around the wire. This is quite feasible if you have a wire with a few KV to ground. The classic demo is to light up a fluorescent lamp by placing it vertically below a high tension line. [zen.co.uk] This works partly because air is not a perfect insulator. There's an electrical path to ground; it just has a high resistance.
If the thing lands on an 11KV power line that's 10m above ground, and has a conductive part that dips 10cm below the line, it should see a voltage difference of about 90 volts. You can't draw very much current before the voltage difference disappears, but you can draw a little.
It's also possible to extract some energy magnetically. See U.S. Patent #3,202,963, "Apparatus for Illuminating Power Lines". But that approach requires heavier parts than an electrostatic approach.

FYI: In a typical power pole situation, you have three wires on top (in sort of a triangle config), and one part way down the pole. The top three are three different phases of the AC power, and the one part way down the pole is ground (you can see the occasional tap where the line is grounded to a stake in the ground). The step-down transformers for the home circuits tap into the ground, and one of the three phases, to give you 220v for several homes. (Factories and such will use all three phases for serious equipment.) Often on branch lines, only one of the three phases (and the ground) will be tapped off from the main line, to service some houses (with skinnier looking pole arrangements with only two wires). The fatter, insulated wires on the poles are cable and phone lines.
