"Smoking Gun" - finally!

[sm0ky2]

i was reading another thread, where the guy was charging a capacitor using earth ground, and 2 series of diodes.
1 in and 1 out..

so i placed 5 diodes in series, x4 sets in parallel.  Each row of 5 is connected to the next with a single diode, to keep current biased in one direction.
at the front, i attached an antennae, and 1 more diode, facing from earth ground INTO the front of the array.
the diodes go to 1 leg of the capacitor.
then i have 10 diodes from the other leg to earth ground. (heading out)
Across the entire array from the antennae to earth ground i have a steady 0.07v (70 millivolts)
i cant measure the impedance of the circuit, i just know that it exceeds 1MOhm, so there is LESS THAN 30 picoamps flowing through this circuit

This circuit will charge 2 capacitors up to 1.5v, in 45secs to 1 min.

Capacitors are::  50v 10 uF     and  100v  100 uF
charge time seems to be he same between the 2, but they ARE connected in parallel.

my larger capacitor (4700uF) will charge up to 300mv after sitting for 1 hr in the circuit.

it seems to max out in either case, but this is thousands of times more energy that is being discussed with a simple diode array.  Something to think about....

Hi sm0ky2,

Yes, there are earth energies, natural and mad-made. The only problem is that they can vary from location to location.  The great thing about diodes rectifying ambient thermal energy is that it does not vary from location to location, with the exception of ambient temperature of course. Often one has to actually go out of their way to detect such earth energies; e.g., a long wire or antenna. I never saw Earth energies in my diode array, but to be certain I use an extremely small diode array, two layers metal shields, and place the diode array inside an oil bath.

Did you tested ever, cool down the whole diode array with liquid nitrogen meantime testing the output?

No. To *properly* perform that type of test could take years to fine tune, if it's even possible with present technology. The reason being is that the entire setup (including the electrometer) would have to be cool as well. Otherwise the thermoelectric DC voltages would be in the measurable range. Also, such a test would still be inconclusive because diode *behavior* changes with temperature. So we would not know if the drop in DC voltage was due to a drop in ambient thermal energy or diode behavior.

IMO, it would be far easier and cheaper to just build home brew semiconductor fabrication equipment, build a diode array chip, place under appropriate resistive load, and test to see if the chip temperature drops.

Also, such home brew semiconductor fabrication equipment could easily allow one to make their own affordable solar cells, and even LED's. Someone gave me some papers on a students University lab sheets provided by the professor that shows how to make LED's using home brew semiconductor fabrication equipment that the professor made. They use a simple rotary pump in-series with a diffusion pump to make the vacuum. They deposit the material, and use a tungsten coil to heat it up. The materials atoms inside the vacuum will evaporate onto the wafer. I'll try to upload those papers sometime this week.

Don't you think the diode behaviour directly connected to ambient thermal energy?

Diode behavior is not linear with temperature. Every diode is different. The peak rectifying efficiency is different for each diode. One type of diode may peak at 120F, while another at 150F, while another at 80F. I'm certain it's possible to build diodes that have a peak at -50F. So if the temp is 80F, and you drop the temp in such a diode, then the rectified DC voltage would actually increase.

Also, when you start getting down into very low temperatures, below 200K (-100F) there can be sudden changes in the materials. It is expected that there would be appreciable changes in diode behavior at various low temperatures. So it's nearly impossible to tell if the drop in DC voltage from rectification is due to a drop in ambient thermal energy or a change in diode behavior.

Also, it is possible that the diode has multiple rectifying peaks. There could be various rectifying peaks at such low temperatures.

It's been a while, and have made a lot more DC voltage measurements on the 156 in-series SMS7630 diode array since last in this thread. It's all nothing but great news, and is revealing the true nature of diodes. Last night ended the 156 diode array measurements while connected to a 2M ohm load. Tonight's scheduled 156 diode array measurement is the start of new measurements with no-load while connected to only the 4.7uF Mylar capacitor. Actually all caps have parallel resistance. I'm guesstimating this Mylar is about 5G ohms parallel resistance.

It appears the diode array DC voltage stability increases as the load resistance increases. The 2M ohm measurements were rather stable, or about as stable as one could expect from rectifying purely random noise. We'll have to see how stable it is with exceptionally high resistance load. Also the DC voltage is expected to increase over time, as it appears that the increased trapped carriers over time from flicker noise increases the diodes small signal resistance, which in turn increases the diodes thermal noise. If true, then diodes slowly adjust to the load resistance, which would be cool (pun intended  ). Also, it appears that the rectifying efficiency increases with an increase in resistance. I'm taking a massive guesstimate that the diode array could approach 50mV DC across the Mylar capacitor, that is if it's around 5G ohms.

Hmm, dare even say that if this trend holds true, that the 156 diode array could produce enough light to be seen inside a dark room across a 1T ohm LED?
