Cell Phone Vs Telephone

[hazelm]

The state of California has warned its citizens that cell phones are indeed dangerous to one's health.  So, somebody please tell me.  What is in cell phones that is not in Alexander's telephones?

 

I was going to say that among the dangers (like brain cancer), they didn't list the one thing I truly think is a danger: addiction and its negative social results.  But then I remembered the 50s and 60s teens tying up phones for hours.

 

Anyway, back to my question.  What is in cell phones that is not in Mr. Bell's invention?

Could it be the potential fire danger posed by the batteries?  I've noticed that mine does heat up sometimes, though so far, not yet to the point of combustion.

All right but my cordless phone has batteries.  I've been hearing a lot about batteries exploding.  We have batteries all over the place now.  They wouldn't cause brain cancer?

 

I went back to find what I'd read.  I did not find it but did find this one dated 16 December 2017.  It is probably from the same source but written differently - no list of health threats.

It seems radiation is the problem.  So, what is the radiation from?

The radio.

The radio.

Thanks.  I am showly getting this put together.   I don't think there are radio waves in m little $20 cell phone that does next to nothing but make calls and-if you know how - text and take pictures.  Anyway.....

 

By the way, I love your little kitty-friend.  He looks as if he knows more than I do which is entirely possible.

Yes, there is a radio. That's how it communicates with the local cell phone tower.

 

A regular corded home phone does not use a radio, it uses the wires.

 

A home cordless phone uses a radio, but (to my knowledge) lower power than your cell phone, as the range required is much less.

I did not know that.  You see, if you can teach me how to use it without me learning all the technicalities, I am happy in my innocence.   When I got my first computer, I thought I wanted to know all about its innards and how it worked.  I bought a book, took one look and said forget it.  I've been computer-handicapped ever since.

 

Thanks much.  I did wonder about my cordless phone.  Now I know.  Handy little critter, being loose like that.

You have noticed that mine does heat up occasionally

How is that possible?

I don't know, 'Farming Guy' has wrote about it, maybe you should ask Farming Guy

Completing a circuit with any battery/electrical source is inefficient: The wires and everything else have electrical resistance (not just the "resistors"!), and that is converted to heat energy.

 

So, when your cell phone just sits there, especially if it's turned off, it'll be cold. But talk on it for a few minutes and indeed it will be warmer.

 

The very high-speed processors they put in phones now are even more prone to heating up because they've got a billion switches in them that are going like demons when you're using them.

 

The upside is that they're great hand-warmers in the winter! :cheer:

 

 

Where there is power, there is resistance, :phones:

And where there is resistance there is power.  Turn the thing off!  My neighbors had started out on their little Christmas weekend journey yesterday.  They got a few miles down the road when their phone rang.  The boss (highway department) saying "this looks like a bad one; better come back home."  (Snow storm).  So, back they came, had a good night's sleep and waited for boss to call again.  He did.  "Turns out it was not so bad after all.  Go ahead and go."  So, now they are traveling again.  I told them to turn off that phone!  Resist!  :cussing:

Actually, I have not noticed anything about yours.

It might be possible if I was monitoring the phone belonging to DingerM786, but I'm not, and I didn't.  Honestly

Actually the exhaust pipe on the tractor is much faster, but keep the gloves on while warming hands by this method, and don't linger.

Not all of us have a tractor, guy.

 

Plus, they won't let you bring it into the football game.

 

 

A lot of people like snow. I find it to be an unnecessary freezing of water, :phones:

But the thing is you wont be able to because my phone will rip your brain apart, that's how powerful it is

While tin cans do provide some capability for transmitting sounds, I doubt most people would call them "phones."
