Trawoeer Power Pyramid Version 12 - Electrical output from a homemade pyramid

[neptune]

@Pascuser. I am sure that Ben will give us the measurements when he gets the parts . I would say that the large copper tube is definitely 29-30 mm because you can tell this just by comparing it to the plastic tube on the video . Also on video number two , compare it to the small 10 mm tube . It is obviously about 3 times bigger rather than 2 times . If you can not get adapters of the correct length or diameter , you may need to find someone with a lathe to modify them . I hope this helps .
     Another thought I had . The walls of the pyramid do not just act as a reflector . If they did , then the reactor would still work  with different sizes of pyramid , just as you can use a bigger satelite dish with the same LNB[ the bit that sits at the focal point} I think that the inside of the pyramid acts as a resonant cavity , and the size of the reactor has to match the resonant frequency of this cavity . Just a theory .

Thanks for your informations. I yet noticed the same thing in a previous pots: capacitor and coil are in my mind tuned to a frequency that is characteristic of the pyramid size. So I will calculate mine to have a product LxC that will be half of the one Thomas had. To calculate this I need all measurements (wire diameter, insulation diameter, I can find the dielectric material, etc) to adapt to a small scale.

Another thing to measure: the wire. Thomas said it is 1.5mm diameter but the only thing I can find everywhere is 1.5mm², this is a surface and not the same. We have 1.5mm² or 2.5mm² in all shops for lectric wire, with a single wire.

So I suggest that it is 1.5mm² and not 1.5mm in diameter. Then if it is the case, you have a wire diameter with insulation of 2.5mm (I measured it in various shops for 1.5mm² copper wire inside).

It is obvious that Thomas went to a lot of trouble to make videos . But it is almost impossible to make 3 hours of video without slight mistakes , or leaving something out . It is a good thing we have Ben , who in time will resolve all the very small details . If we draw the wiring diagram as a schematic , it can be seen that the inner and outer reactor coils are in series [most likely series adding ] and the copper tubes and sand cause it to have increased self capacitance . The capacitor [which consists of a sort of bifilar coil ] is connected in parallel with the reactor coils . So the whole thing becomes a parallel tuned circuit . What would be very useful if someone who gets a reactor built to close specification could measure its resonant frequency with a Grid dip oscillator , or a scope and signal generator . Also , on his website Thomas says he he will give a formula to calculate the reactor for other pyramid sizes . I am not sure if he has shown it yet , but we know it exists .I would guess that the resonant frequency of the reactor is between 10 and 20 Mhz.That is just a guess.A Rough estimation of the wire diameter measured to include the insulation . Looking at the video , we know the distance on the inner copper tube between the 2 holes , and we know the number of turns . Simple mathematics .

I can't have this distance; only and idea approximately. About 27cm I think with videos, but nothing exact.

Thomas gave much and I don't criticize at all, he did a great work. There is some small lacks to have an identical replication.

Thomas said calculations formulae would be given but as he said he had to test it; so he hasn't it yet. And with the bad news of non working adaptation with US norm tells us that these formulas doesn't yet exist. It's research and everything can't be given like on a plate. This seems normal; and one times more i don't criticize. But if we can have precise measurements; and the resonant frequency as you suggest it would help to make our work with it too!

hi all

please excuse the following 'damn fool' questions - i have a quota of them to fulfill, so i can justify my position as resident damn fool

has anybody asked to see, on video, a clearly-derived scope trace and  DVM reading of the unloaded and then resistive-loaded o/p voltage from this Giza?

if not, what convincing argument is produced to explain why these are not forthcoming?

seriously now, this is not a criticism - it is a valid technical query

if this data exists, could someone please provide a link?

many thanks
