Joule Thief

Xee2:

Nice circuit!  I'll bet this will light and 18" and then a 48" tube easily.  That is a very bright 4 watt tube you have going there.

I know this was posted way back somewhere, but where did you guys get those large toroids?

@ jeanna

will you please time this on your battery?

You do not need to time, just calculate.

hours = (battery mAh rating) / (battery drain mA)

for AA battery the mAh rating at 200 mA = 2200

hours = 2200 / 200 = 11

NOTE: mAh is milliamp-hours

some of the other circuits I posted had less than 100 mA battery drain:

mAh rating for AA battery at 100 ma drain is 2500

with 100 mA battery drain > hours = 2500/100 = 25 hours

A buddy of mine on Youtube posted this and asked me to bring it to your attention:

He did not film this and it is in some language I do not recognize but it is what appears to be an earth battery, joule thief, spark gap (Jeanna will like this) and God knows what else and they are lighting about a dozen incandescent bulbs from it.

It is a 7 part series (the link above is for part 1) and maybe someone here will be able to figure out what they are saying.  It is very interesting to say the least.  I can't quite figure out what they are doing even though I recognize some of the components.

they bury an automobile? radiator that appears to be empty (i am assuming that's why they rolled it all about and turned it on all axis) wetting the ground while burying.

i think i learned a new swear word in vid 2 @ 2:52 
i'm only on vid 3 but this is very interesting. a 'cobbled' tesla coil on the outside of a large green box. what's in the green box? i'm curious to see how it ends. did they use the 12v car battery to 'charge' the radiator in the ground? does the water pipe run near the radiator under ground?

back in an hour or so when i get done with the rest.
thanks bill.

edit:
maybe ask the user 'forest' to take a look. he might know the language.

@ All:

I started a new topic here:

http://www.overunity.com/index.php?topic=7679.new#new

for anyone that wants to discuss the earth battery geo videos posted on Youtube.  I didn't want to get too off-topic here even though it is related, since I don't know how it works I don't know if it has a joule thief or not.

@ Wilby:

Yes, I believe that was a swear word, ha ha.  Looks like he got bit when he flipped that switch.
