Prepare for drones that ‘perch’ on power lines to recharge, never have to land
The Washington Times ^ | April 9, 2014 | Douglas Ernst

(VIDEO-AT-LINK)

Imagine a world where drones never have to touch the ground after takeoff. That’s what MIT PhD. candidate Joseph Moore did, and now he’s on the cusp of creating a drone that can “perch” on power lines just like birds to recharge its batteries.

Mr. Moore gave Business Insider a demonstration of the technology he’s perfecting by using a glider as proof of concept.

In short, if a drone is equipped with the a magnetometer it should be possible to make the aircraft capable of identifying magnetic fields given off by power lines, home in on the signal they emit, and then maneuver in such a way that would allow the drone to perch until fully charged.

Developing such a system for fixed wing aircraft is desirable because of their ability to carry heavier loads than those that use a quadrotor design, Business Insider reported....

I used to pick crows off the lines with a pellet gun when I was a kid, these won’t be much different.

Another use of induction from what I understand. Just need to have the coils in the drone in the right place.

For those of you who never took first year physics in college.

The power of electricity is about differences in voltage, not the absolute voltage.

A 10000 volt line is at 10,000 volts when measured against the ground. So if you are standing on the ground and grab a 10k volt line, you will get zapped with 10k volts of electricity.

Now if you are standing on a copper plate that is hooked up to a 9999 volt line and grab hold on a 10000 volt line, the differenct is 1 volt and you will not feel much of anything.

Now when a bird lands on a high power line, one foot might feel 10,000 volts and the second foot might fee 9999.99 volts because the feet are close together.

This difference will not zap anyone or anything but is small enought to zap a bird with about 10 volts,

Now if a bird lands on a power line and you throw the bird a line connected to the ground, the bird gets zapped.

Can’t wait for PG&E or SoCal-Ed to chime in on these parasites on their transmission cables.

Guess I better get back to work on that Magnetic Pulse rifle I’ve been designing.

I wonder what the penalty for frying the circuits of a snooping government drone will be?

Unless the line the bird is standing on is insulated.

It might make more sense to get near a transmitting tower.

I don’t think most high tension lines are. It would be quite expensive.

At voltages high enough, they could siphon off significant power by deploying panels of sharp pointed spikes opposite to where they perch on the wires. The spikes would corona-off into the atmosphere, and a flow of electricity would result from the perch to the spikes.

But this would have to be very high voltage lines. The 5000 or so volt lines that feed pole pigs probably couldn’t be corona drained.

Current li chemistry does not allow as many charge/discharge cycles as you might expect, especially for high-discharge rate cells. The cells can start deteriorating after only 10-20 cycles in some instances. So the drones are going to be coming back to home base for battery replacement before long anyway.

If it even uses Li-Ion. I’d think chemical fuel more efficient.

I think that this just might be the right tool for drone extermination.

Thanks for getting the reference. Star wars trivia: the guy who said that line- actor Denis Lawson, who played Wedge in the original trilogy is the maternal uncle of Ewan MacGregor who played Obi wan Kenobi in the prequels.

I’m not positive about this, but I think that it’s very difficult to insulate very high voltages.

And you better pray to God that the bird catches it!

You know if you shoot at the drones and miss a little low, you might take down the power line for a few thousand people.

Probably too far apart. The drones want to carry small batteries and stay close to the target they are observing.

No such thing. Since magnetic monopoles are a huge rarity, you can only have an EMP rifle (electro magnetic pulse).

Maybe Fedzilla shouldn’t be employing legions of UAV and UAS to spy on American Citizens. Maybe “a few thousand people” should vote for politicians who won’t tolerate gross violations of the Fourth Amendment.

A low velocity .22 probably won’t damage a power line & anyway a perching drone will be larger than any bird.

Seems that the best way to avoid hitting a power line is for the line of fire to be parallel to the line.

...yes, a lot easier to hit sitting still...can use a 7.62 scoped rather than a shotgun.

Well if you can’t shoot, don’t! I doubt seriously they will be charging on the high tension lines, so probably just a block or two! I guess we should all just bend over because fighting back is just too darn risky.

Better find out where their “blind spot” is before you approach for the shot...

Of course, long distance shots could come from “anywhere”.

That's true, transmission lines are not insulated however lower voltage distribution and service lines usually are.

A buddies kid has one he built out of an airsoft rifle and a bunch of spare parts that would put a steel slug through a beer can from his bedroom window to the back of the yard.

I figure if you can get that with ~20-30 bucks in scrap, someone should be able to make one that hits with authority for a few grand...
