Energy from the Ground - Self powered generator by Barbosa and Leal

[ramset]

Does anybody have any suggestions on a signal generator that can do what this one does
[or better]

the above is a bit over present budget.
used or otherwise?
all suggestions welcome [it would be going to  the UK]

thanks

Yeah, tell Cangas Khan that I am going into my evil underground lair for bad guys to get my beauty sleep.

While Dragon has surprised me by posting even that much, it should be clear that the circuit diagram above is _not_ complete. There is no indication of the turn count on the "primary" of the toroid. Nothing about toroid material. Nothing is indicated about the _input_ to the inverter, the inverter type (make and model), or how the input and output power measurements were done.

One of the basic requirements of the scientific reporting of "experiments" or even patent applications is that the information should enable someone "skilled in the art" to reproduce the experiment or device and (potentially, no pun intended) to get the same results as claimed. There isn't enough information in Dragon's diagram to do that.

I'd like to know the make and model of the inverter. Is it possible that the measurements are of _reactive power_ circulating in the output loop?

Any function generator capable of over 20MHz output will be similarly pricey. For a 100MHz 2-channel AWG this is actually surprisingly cheap.

Yes the newer models that can be hacked and do Sooo much more are leaving tonnes of
used units on Ebay for much less money.

I just can't pic a winner so easily ...
