Question

Microwave frequency is approximately equivalent to Wifi frequencies (2.4GHz).
This is why microwaves can disrupt your wifi signals.

Now consider extracting the microwave-generator from a microwave, and assemble it into a sniper:

Answer 1

You can also being it as a portable food-cooker

Answer 2

And create fires with tin-foil



So the question becomes...why hasn't such a useful tool been utilized yet?

Answer 3

here is a little bit of something on this:

the idea sounds plausible in theory, but if you examine the science, with backyard tech, it would be hard to achieve such a thing

Answer 4

XD

Answer 5

Also, your real trouble is amplitude. How could you reach a distance like you describe in your diagram. I do beleive you might be able to start fires. But there are simpler ways to do so. Like a lighter for example, but if you want to be sciency use a 9 volt battery, and steel wool.

Answer 6

It's actually not that hard, just disassemble a microwave and take out parts like the magnetron and capacitor. Then reassemble into the preferred gun. And I'm pretty sure this has been thought of in the past and has prototypes. The issue is the risks knowing how egoistic the human mind can be.

The most probable reason why whe haven't mass produced microwave guns is because with that, we'll need to wear tin foil hats and tin foil clothes and live in faraday's cages.

Answer 7

And yeah like Gdein said, this isn't like an infrared laser gun that can go very far. It will most likely only work on things within a 1-meter distance

Answer 8

The reason I said hard, is because of the distance he wants it to reach. But assembling the gun wouldnt be hard, no.

Answer 9

yeah exactly

Answer 10

Electromagnetic guns would be useful in warfare though. Not microwaves necessarily
