Killer Drone: The drone with a chainsaw attached

Technically Incorrect: Some Fins decide that drone weaponry needs a new twist. So they build a tool that's very useful. Or not.

Technically Incorrect offers a slightly twisted take on the tech that's taken over our lives.


What fun.

Everything's up in the air these days.

Our political system and soon, thanks to Amazon, even our new underwear.

So inventive minds are thinking about all the different uses for drones -- and, of course, all the different things that can be attached to them.

A hacksaw, for example. One that can slice the head off a snowman. Because you've always wanted to do that. (Snowmen can be so big-headed.)

Finns Miika Ullakko, Antti Kunnari and Henri Kiviniemi got together to create a hacksaw drone. Or, as they charmingly describe it on YouTube: "Killer Drone, the Flying Chainsaw."

Yes, it flies through the air and decapitates all that gets in its way.

The hacksaw is remote-controlled. The joy is uncontrolled. There were, though, a few design glitches.

"The drone was on the limits of its carrying weight and couldn't fly longer than approximately 5 minutes with one battery," Ullakko told me. "It was also super unstable, because the saw creates huge momentum, not only because its heavy, but also because it's so long."

And then there was the problem that the saw had to work upside down. The team "flipped the fuel system."

It still isn't that efficient.

"Saws don't work very well neither upside down," Ullakko told me, "since the oiling system of the blade seems to need gravity. We put some oil on the blade manually every time it was down."

But why create it? Ullakko told me it was "mainly a joke to parodize all these ridiculous ideas of using drones in carrying mail and other nonsense."

There has already been some considerable drone nonsense. The drone with a mounted gun, for example. So I wouldn't encourage anyone to emulate the hacksaw idea.

There again, I feel sure that someone is already preparing the next insanity. An AK 47-wielding drone, perhaps?
