Tech talk: what about that Faraday cage that protects you form your microwave oven?

in #microwave7 years ago

Michael Faraday

Somewhere around 1836 (long before we made cellphones and microwave ovens) Michael Faraday came up with the concept of a cage to block electromagnetic fields.

Al perfect science in 1836, nothing wrong with that.

But technolgy evolves, and we take science facts for granted

So military technology eventually starts to explore microwaves to build radar devices. And while playing with the technology they discover that it can boil water and cook meat. And the microwave oven was born.

Then first the tech-nerds got exited and they bought into this technology. After them the tech-sceptics got nervous about having a 1000Watt microwave transmitter in their kitchen. And that lead to 'FCC approved' kitchen appliances.
FCC allegedly test if the Faraday cages of microwave ovens are build according to the scientific 'FCC standards' that a bunch of financial backed scientists of the industry happen to agree on.

All perfectly fine, right?

Microwave oven technology.

Frequencies around 2.5Ghz happened to work good for this purpose, as water molecules get exited at that frequency and start to heat up. Again good science, right?

Then another technology, radio communication, took microwaves on to another exiting path. And all of a sudden cellphones started to use frequencies around 2.5 GHz for communication.
Cellphone towers of several kilowatts are placed all over the planet, blasting microwaves into the world like there was no tomorrow. But now it all of a sudden was safe to do so. Yet microwave ovens still must be build like FCC rules dictate.

All fine.

Now lets put the two together and use the 3 technologies to test echother!

How?

Now this is where it gets interesting.

  • Invite a friend who has a cellphone.
  • Place one cellphone into Faraday cage
  • Then use another cellhone to call the number of the other phone.

Does the phone IN the Faraday cage start to ring?
Does this prove that a Faraday cage still works at 2.5 GHz or not?
Does this put FCC microwave rules into question?

If a Faraday cage allegedly shields 2.5 GHz from a microwave oven from blasting out, into your kitchen. Then it also should be able to shield a 1000 watt cellphone tower located a mile away, right?

Then WHY does your cellphone receive the call signal while being INSIDE of a Faraday cage?
And why would it be safe to have a 1000W microwave oven IN a Faraday cage IN your kitchen and have you standing next to it while cooking?

What is good science in this case?

YOU could do the test with devices you own and prove that things simply don't add up.

Having any doubts?
Having a bit of anger about not being told the truth?
Or is this nonsense?

Do you trust your OWN findings. Or do you trust the FCC?

Let me know, in the section below.

This is very interesting.. I've heard a lot of talk about the safety regulations set by the FCC regarding cellphones but I'm no physics major and have no experience really with RF so I have little real knowledge. With that said I did look into microwaves being Faraday cages and it seems this is quite the argument as well.. some people say they definitely are others point out there are spaces/holes in the microwave oven which makes it an incomplete-ish cage.
Not sure how reliable this site is but I found this one to be interesting:

let me know what you think

this one is very interesting and on the side that cellphones are more dangerous than the FCC is claiming

'We' don't understand but probably someone knows what this is all about.

the s-human resonance? ;-)

nice docu, thank you!

all is frequency, and all is empty space.

Seem my dark matter article about some of that hehehe

also look up benzene rings in human cells. their size and what resonant frequency that resembles. link that with water (90% of our body) and DNA

:-D

ohhh yes, I was a chemistry major ;-) the geometry of biology is very beautiful and when we look at matter in general we start to see the hexagonal structure evolve into 3-5-8d and a tetrahedron as it does so.. and as for the water frequency I'm sure you've seen Dr. Emoto's studies and images? so profound - glad you liked that one, I thought it had some pretty interesting parts

the hexagonal benzene ring, what size is that? and how does that saze compare to frequency.. as in a ring antenna...
Where do i find the tetrahedron ? That's an interesting one! the strongest structure in the universe.
The benzene rings as antenna (resonators) can be exited. And what happens then?
Masaru Emoto can answer that for sure.

It depends.
If you want to be shielded from high voltage high frequency electro magnetic waves then a Faraday cage may work. But if you put your cellphone in a cage, and let someone else call you...
Well, give it a try and let me know the result. :-)

For high voltage there is a skin-effect and THAT travels on the outside of a cage to the ground.
But what happens with the cellphone signals is not explained by science as far as i know.

So how FCC can claim to make a difference between safe or unsafe cellphone signals is beyond me.
Before you can make that claim you have to be able to measure anything. And my experiment above shows you that there is a massive gap in science. I think i know a part of the answer, but i'm not a big name scientist. And the little part I know for sure that's how I managed to get to this experiment.

I have viewed the entire MIT course on this topic but could not find anything in there that could explain this. https://archive.org/details/MIT8.01F99
Some subjects get close but they are about high voltage, and that's where a cage works just fine. :-)
Once the rest of internet discovers this article then some people will most likely ridicule me. Yet my experiment will still work.

Let the bullshitters reveal themselves.

Come kitty kitty.... it's a challenge. Not a textbook recital game.

hmm very interesting. im gonna try putting mine in a microwave see if it rings :-D
