Wireless power transmission

Using Arduino General Electronics

Paul__B: It is the (AC) electric field. That is why the explanation given is so badly wrong as it refers to the magnetic field which is extremely weak as it essentially only exists between the wires themselves.

What you describe there is exactly how the tubes operate in their normal configuration; in this case the actual current - and so the brightness - is very small (and painless) but the voltage is so high that the gas can be ionised without the cathodes hot.

Thanks for mentioning all that Paul. Definitely nice that you and Mark mentioned those things. Not great when the wrong info gets passed along like that (on that website).

Theres no differance at all between 1 and 2 other than efficiency and how much power you need to transmit and how far you want to transmit it .
You can theoretically transmit 50 hz over very long distances if you want, but the difficulty is making an efficient 50 hz antenna. ( a 1/4 wave 50 hz antenna is 1500 kms high )
If you stand near a large power transformer with an audio amplifier and a loop antenna you will easily hear the
50 hz hum being radiated.
Hi frequencies like 2.4 Ghz and 433 Mhz are easy to transmit long distances simply because its easy to make efficient antennas at these frequencies.

Totally agree with you. The practicality of a 1.5 million metre length antenna hahaha.

There is no Connection so you can't really call them Option-1 and Option-2 because WiFi and Bluetooth are not charging technologies. They are DATA TRANSMISSION technologies and proximity charging is NOT a data transmission technology. In short , they should NEVER share the the same paragraph. Talk about one and then wait a day before bringing up the other one.

Sorry, I actually speak English. :sunglasses:

Present Tense

That's wierd, present tense is spelled with a "z".

Who decided it wasn't good enough for the PAST tense ?

Ionization or ionisation, is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.

Looks like either spelling is accepted.

My bad.

It depends on which dialect of the English language you use!

How many dialects of English are there ?

I thought there was only the U.K. (the original) and the U.S.A (derivative).

#20

Exactly. The UK "original" uses "s", the American uses "zee".

#21

Sorry, I'm an American...

Sorry, I actually speak the King's English

#22

I do not know about other places, but in the U.S.A., the letter 'z' is used much more that it is in the U.K.

#23

Could it be because we watched "Zorro" when we were kids ?

raschemmel: There is no vonnection so you can't reallty call them Option-1 and Option-2 because wifi and bluetooth are not charging technologies. They ar DATA TRANSMISSION technologies and proximity charging is NOT a data transmission technolgy. In short , they should NEVER share the the same paragrapgh. Talk about one and then wait a day before bringing up the other one.

Thank you for the response, i was just confused because (Mauried) told me that there is no difference.

#25

That's odd .

I thought everyone on the forum was always correct...

#26

raschemmel: Sorry, I'm an American...

Sorry, I actually speak the King's English

We are not amused.

I was posting the question to see the (difference) between the two. If you say that they have nothing related then could you explain why, please? and is my comment #10 correct the way i explained it? Thanks

#28

I already explained it. One is procimity charging technology with absolutely nothing to do wgh data transmisdion whilewifi & bluetooth are exclusively data transmission with nothing to do with charging. Why isthat so hard to understand ?

#29

"We are not amused..."

The classic "Royal" "We" ...

#30

Paul__B: Exactly. The UK "original" uses "s", the American uses "zee".

You clearly don't have the Oxford English Dictionary then! These are greek endings and z is logically correct. The OED recommends -IZE, but recognizes that -ISE is commonly used in British English.

And its pronouned -IZE of course, not that pronounciation is a good guide in English anyway!

The complication is some -ISE only verbs like advise, promise, excise, see https://www.lexico.com/en/grammar/ize-ise-or-yse

raschemmel:
The classic “Royal” “We” …

Not to be confused with the “Privvy”. :roll_eyes:

If you search the reference I gave, it is suggested that Victoria was in fact, not using the royal “We” on the particular occasion apocryphally recorded.
