Joule Thief

This one didn't post for some reason.

First it is a 4 watt tube. That means it uses 4 watts when plugged into 120 volt AC supply.

I am surprised you asked about this. If you replace your 10 ohm resistor that you connect in series with the 1.5 volt battery to measure current with a 100 watt 10 ohm resistor do you really think that the battery is going to deliver 100 watts into it just because it is labled 100 watts? The 100 watts is the maximum power that can be put into the resistor without damaging it. Consider it a game. When you see something that says "100 watts" you need to play the game of "what in the world do they mean by that?".

I respectfully disagree.  Input power to my earth battery-joule thief-supercaps circuit=0  Output from circuit=1.95 volts, about 12mA's....enough to light the 48" tube, and soon (hopefully) much more.

Your EB is just like any other battery except you made it yourself. It gets its energy from the electrodes which are used up in the process of generating voltage.

your resistor example is truly what to expect from the watts rating of any electric componants and/or appliances.

but, to me, your first statement is somewhat contradicting your resistor example.
i would say : it can support up to ~4 watts without degrading too fast or blow up.

But, you are correct in that it is the EB doing this and not the JT.  I am just using the JT as a tool which, by itself, is not OU.

it can't be called OU.
if you could, any alkaline batteries would be OU devices.

it is a free source of energy, yes, just like wind and solar.
but like everything else, tapping it technicaly cost something.
