Where the OVERUNITY using INDUCTION COILS comes from (eg Joule Thief)

[verpies]

Do you not get more current if you move a magnet across a coil faster?

You do not - you only get more voltage (emf) if the coil is not ideal and not perfectly closed.
...and if the coil is ideal and closed, then voltage cannot be even measured across it.

I always liked Don Smith's "watt second" for a current measurement.

But "Watt Second" is a Joule - a measure of energy (not current).

Hi all, Hi pfrattali, have you built something that hints at this or could you share what specific devices that were actually built, that you feel are exhibiting this idea, thanks.
I ask, because I'm working on improving the efficiency of a boost circuit i have, joule thief style, i have so far been able to equal and slightly exceed the efficiency of a 600 watt boost converter i bought from bang good.
I'm wondering if using an air coil might give higher efficiency, as it would certainly fit the criteria of higher frequency.

It says up to 95% efficiency.
peace love light

How do you define current if you don't consider it energy?  Isn't 'horsepower' considered energy?

Let me ask you something. Do you consider the Kapanadze circuit a scam?

"How do you define current if you don't consider it energy?  Isn't 'horsepower' considered energy?" all units have been defined.
Wikipedia gives excellent definitions. Learn them, but don't try to change them.
