Copper Steel Plate Battery using Rochelle Salt and Cotton Wool
In reference to http://docsfreelunch.blogspot.com/ . Doc mentions a honey cotton wool and copper zinc plates as a good starter point and the low power circuit is handy.
So I built a rochelle salt ,copper and steel plated battery with cotton wool insulation.
The rochelle salts is made by mixing sodium carbonate and creme of tartar. Firstly heat gently vinegar and add slowly the sodium carbonate. Allow enough sodium carbonate to be soluble. Add the creme of tartar until no longer solubable. Cool down after the mixture has thickened.Place cotton wool on a steel plate and pour mixture on the cotton wool. Press the copper plate on top and allow to cool. Once cooled ready to measure the voltage.
Here is a picture of the battery measuring 964 millivolts with a capacitor in series. The capacitor had no charge before attached to the battery. Measuring 20 micro amps puts this battery at about 18-15 micro watts.

Digital Oscilloscope Readings of Dr Jones Circuit
This new circuit uses a darlington pair of bc547 Low Noise Transistors 50V at 100mA. I am measuring the voltage across a 1 ohm resistor in the ground loop between the battery and the circuit ground. I am using a variable capacitor 50-150pF as well as a 500K ohm variable resistor. The toroid is wound approx 15 turns triple wired the extra winding provides the green led. The Green trace measures the input power. The Yellow trace measure the output voltage across the green led.
This circuit operates at 208kHz and is consuming on average 15-20 milliwatts. The output waveform is approximately 10V peak-to-peak. I am currently constructing a diode bridge to measure the output power.
It turns out that i was measuring the input power incorrectly.
I tried using two similar 1.7 ohm resistors and connected the diode bridge.
The yellow trace represents the output power. Green is the input power.
I must say this looks like an overunity.

Clauss Turtur Zero Point Simulation
Clauss Turtur has written a paper on the zero point energy using mathematical modelling.
The simulation uses a diametric cylinder magnet.
I have replicated the simulation in scilab.
Period: 0.000277 seconds Frequency: 22691.508773
Inductance: 0.37Mass: 0.37 Inertia: 0.00028345

end
The simulation graphs:
3amps Peak-Peak
The magnet is rotating in reverse at -450rpm so an increase of speed will increase to the negative.
Simulation is increasing at 228 ohms resistance any higher the system will slow down.
The trick is to wind the coil bifilar to amplify the Inductance while in keeping the resistance of the coil down as low as possible to achieve over-unity.
Another method would be to use a stronger magnet or higher initial speeds.

Joule Thief Over Unity Ciruit
The replication following is a circuit derived from Dr. Steven E. Jones joule thief circuit outlined in Figure 1.
| Figure 1 Dr Jones Joule Thief Circuit |
The Rb chosen was 2k ohms. R0 was set to 5-10Kohms.Cb was set too approx 150pF using spare parts from a old TV set. The Transistor is a BC548 standard general use low power.
The Circuit is Connected to a 6V battery the battery reading was close to 5.99 when read with a DVM.
The circuit input current is measured by a 1.5ohm 1/2 watt Resistor. I measured this with the DVM at 65.5mV 65.5/1.5=43.67mA
Power is measured by Pi=VI=6x43.7=262milliWatts.
I then connected a 20-led bulb in parallel to the 10k Load Resistor. Also I attached a 10ohm current measuring resistor. With the DVM I measured this input power again 71.9mV. The current is 71.9/1.5=47.93mA. Pi2=6x48=288 milliwatts.
Finally I measured the ouput current through the lamp. A reading above of 8.04Volts. This however is an AC signal half wave rectified so this will give us the average power through which is acceptable.
The DVM reading from the sense resistor was 96mV. Current becomes 96/10=9.6mA. Po=8.04x9.6=77.2milliwatts.
efficiency n=Po/(Pi2-Pi)=77.2/(288-262)=77.2/26=2.96

Hidro SouthEast Queensland Gravity Generators 50MW for 3.75M$AU
http://peswiki.com/index.php/Directory:_Hidro_--_Water_Pressures_Energy_Conversion_(WAPEC)
Hidro looks to be a method of extraction of energy from gravity using the change in pressure of water.
I Look forward to hearing of developments in extracting energy from gravity. Gravity has a much better capacity to supply safely and long term as force is proportional to inverse distance squared. Current methods of linear (VP/T) ambient temperature heat exchange ie modern combustion can not sustain the allowable limits of vehicles and industry. Gravity has a much larger availability for extraction from the environment than temperature heat exchanged to the atmosphere and is safer environmentally.
I am curious to see if Hidro becomes open source at some stage. I gather that the "energy must be free" hypothesis must be true for humanity to become sustainable.
