Is joule thief circuit gets overunity?

@all

How can i make a high voltage static electricity without using van de graaf generator?

whimshurst... but more generally speaking you have two options: triboelectric effect or electrostatic induction.

You can use a Bonetti machine, or a Dirod, or a Kelvin water-drop machine or a few other methods I know about.

What kinds of things do you want to do with your HV static electricity, and why don't you want to use a VanDeGraaf?

My favorite is the Moore's Dirod, but I can get much higher voltages from a Bonetti.

Thanks.. I want to experiment with high voltage because i have a feelling that free energy appear at high voltage but using high voltage transformer is very dangerous because of its high current so im thinking to use static electricity. Another problem is i have no money to buy van de graaf generator and i dont know how to make one.

@Neo-X:

A fairly easy way to create high voltage (up to 20 KV) is by building an electrophorus. Search the net for "electrophorus" and you will find good explanations.

I attach a simple circuit (elctrophorus, 3 HV diodes, 1 HV capacitor) and photos of an electrophorus I built.

It is difficult to find HV diodes and HV capacitors (5 KV or 20 KV). The Chinese will sell you some for a good price, look at eBay. They even send them free of charge from Hongkong, PayPal payment works nicely.

The circuit allows you to "pump" a high voltage into the capacitor by lifting the top steel plate of the electrophorus away from the bottom part (acrylic disk covering an other steel plate) and putting it back (many times).

The handle on the top plate is important and has to be plastic. The acrylic plate is best glued to the bottom steel plate with epoxy. The bottom plate needs insulating "feet" (can be wood or plastic). Note, it has to be disks, rectangular eletrophorus plates give strange results (the charge does not spread evenly).

The acrylic plate has to be rubbed a few times with a synthetic fabric or best with real wool, synthetic wool also worked.

The huge diodes on one photo are Russian 10 KV 100 mA diodes, which I bought from a German surplus store some 20 years ago. But I bought HV diodes recently from China (50 KV) via eBay, also HV capacitors.

The best materials for an electrophor: sheet steel disks (e.g. diameter 300 millimeter, thickness 0,5 mm) and acrylic disk (e.g. thickness 3 mm, has to be bigger than the sheet steel disks)
