The 100 uF electrolytic capacitor connected to 100 Mohm load that's inside the freezer is still producing current. Yesterday it was producing 0.5 mV = 5 pA. That's amazing since the temperature is around 3 F. The piezo element, PS1720P02, connected to 20 Mohm load was producing 0.1 mV = 5 ...

Yet another experiment was added yesterday. On 2010/7/15, 13:50, a 100 uF electrolytic capacitor connected to a 100 Mohm resistor was placed inside a thick small plastic container, which was wrapped inside a very thick sock with two wires connected across the capacitor extending slightly out of the sock. At 14:26 ...

I added two more experiments. 1) A piezo element. 2) An electrolytic capacitor freezer experiment. The rest of the electrolytic capacitor measurements are similar to yesterdays measurements. 2010/7/14 11:31, 1 x 0.47 uF #1, 22 Mohm, 74.4 F, 1.1 to 1.2 mV = 50 to 55 pA, ceramic magnet 13:42, 1 x 0.47 uF #2, 22 ...

The end result of yesterdays experiments is that it might be better to hang two thin aluminum foil sheets in the air by long ultra thin copper wires. As the piezo slowly charges the foil sheets, the force between the them will increase, thus pulling them together. I few calculations yesterday showed that it's doable. ...

The voltage was increased to 269 volts DC, and still no spark or current surge. That's about as high as I'd like to take it for now. This is enough time spent on this right now, but if time permitted I would increase the voltage up to 370 volts, no more. If that still would not do it, then it's possible to reduce the ...

Lately I have not been blogging, mostly because I'm working with academic scientists, and it takes time to make these post. The last paragraph of my following email contains numerous methods to build a microscopic piezo array that could produce usable amounts of power, right now with present technology. Here's an ...

Lots of experiments lately. I built a piezo array consisting of 5 in-series, and then made 3 of those lines, for a total of 15 piezos. After the piezos had settled for awhile, the voltages were tested on *each* piezo. One piezo was producing 5.5 volts. ...

Since all of the piezos and electrets just arrived, I grabbed the AM-240 (ultra high input resistance meter) and measured the DC voltage produced by one of the unshielded piezos, part number PKM13EPYH4000-A0. It was nearly 220 mV, and dropping at ~ 1 mV per second. Note that all of the piezos were disturbed. The ...

About a week ago someone asked me what happens if I shake the shielded piezo setup, and if it would flash the efficient LED. That answer was "no." Again, about a week ago while inside the dark room I shook the shielded piezo setup violently, and far longer than ever before. It never flashed once. The only noise I ...

Outline: On Friday, 2009/10/16, I ordered 50 piezo elements, and 10 electrets to start a new line of experiments to understand and break the mysterious 10 pA barrier. The diodes & piezos produce sufficient voltage, over 3 volts for piezos, and over 1/3 of a volt for diodes. The passive components are able to store ...
