GSM WORLD

Excellent article !!

http://www.wymsey.co.uk/wymchron/cooking.htm

I tried it at home and it works ! cellphones are way forward for cooking :-)

PRAT(M) declared for all the world to hear...

Except for point 6, which seems to imply some direct communication
between the two handsets.

Does it?

Anyway I suspect this is false - I rely upon Brainiac for my science and
they tried this with 100s of mobile phones. Two is not enough!

It is going to take a long time to cook an egg with a 0.6W transmitter.

OTOH the UKs 8th Army discovered in Egypt that you could easily cook and
egg on the mudguard of a landrover.

I suppose to be picky it needs to be pointed out that the Land Rover
wasnt devloped until after the 8th Army had left Egypt

This very much depends on the power output of your mobile phone. For
instance, a pair of mobiles each with 2 Watts of transmitter output
will take three minutes to boil a large free range egg.

Lets see. This egg; it is a few inches from two mobile phones with a
maximum power output of two watts. Lets try some thought.

The maximum power transmitted from a GSM mobile phone is 2 watts, but
in a duty cycle of 1:8, so the average maximum power output is 0.25
watts. That power is transmitted in a sort of sphere, but for
simplicity, lets assume it is all in a flat circle.

The egg is around one and a half inches across. So each phone is two
inches from the egg, so the circumference of the signal strength
circle the egg is a part of is 2 x 2 x pi = 13 inches (roughly).

That means that even if the egg were to absorb 100% of the signal, it
would get 1.2/13 x 100% of the signal. It seems sensible to assume a
maximum possible absorption of half the signal.

So the power going into this egg is:

2 watts / 8 (duty cycle)

times

(the proportion of the signal the egg sees)

1.2/13

divided by half because half doesnt get absorbed
doubled because there are two phones

Net result: 0.023 watts

This is a ridiculously high estimate, though. Phones do not normally
run at full power. One hundredth of full is unusually high. The signal
goes out in a sort of flattened spherical pattern. So for real-world
use, we can divide that figure by around five hundred.

A power input of 0.00005 watts to boil this egg. Guess how hot that
will make it!

Now, you may assert that you have successfully boiled an egg in three
minutes using this amount of power input. I can assure you that if
this is the case, you cant tell the difference between a stone cold
raw egg and a hard boiled one.

Thanks for the explanation!

Im embarrased to admit I tried this, just because I, well, could. What
else are the free minutes on ED50 good for anyway? :) (Ill soon move
that to PAYG too...)

15 minutes later, and the egg was practically as cold as when it had
left the fridge. :)
