Peter Davey Heater

[boguslaw]

I think there is main flaw in device. It has open bottom. When I'm looking at Davey video all his devices seems to have closed bottoms with just a tiny output in the upper area. Definitively imho steam is catched inside device, but it's very strange that Davey also put his device slowly into water waiting for steam to show up from the holes in device then he put it deeper to boil rest of water cup.For me it validates theory about steam holded inside device by acoustic standing waves.

this metal "iron soul" was heated by fire and placed inside iron and worked quite well keeping temperature steady for a long time.Remember that boiling water from 80C to 100C is much faster then from 20C

In your video you heat what appears to be an 8oz glass (1/2 lb) of water from ambient 66 to 200 degrees F in approx 134 seconds. (134 deg F rise delta)

It looked to me as if the device was heating the top of the glass of water
rather than the whole bulk of liquid. Maybe there should be a mechanical
stirrer - in a larger glass bowl - heat proof Pyrex preferably.

Alternatively, after a period of, say, one minute, Core could take out
the device, stir the water thoroughly, and then check the temperature.

Because regular thermometers are sluggish to respond, it might be good
to use twisted wire thermocouples. (Many school's Physics teachers will
have some of the wire, and would donate a few inches to the good
cause, particulary if they are kept up to speed with the research results).

I think the vids you are referring to are the later ones where he is trying to engineer around safety concerns from the patent office. That is when the bottom became inclosed. But I do agree with you on the steam bubble needing to be trapped. I think the bells would resonate at a different frequency being fully submerged in water verses being in a steam bubble

Yes stir the water,Get a cheap fishtank bubbler perhaps [steal Goldy's for a trial run]?
We have a company In the US called Harbor Freight ,they have Infrared Therms for 27 bucks! [goin there today Core If you want me to Pick one up]

Also on the GFI... Not sure if it will be worth the trouble ,As I mentioned I work all the time around Elec and water ...Much higher Volts and Amps than we have here, Most times I can't get anything Done if I'm running a GFI
Whilst working in or on the water.
That being said I will be running a GFI at First just to see ??
And to Keep Farrah happy!

I'm actually thinking of doing a quick baseline without Critical tolerances
Just to see what happens with the GFI and Temp!

Thanks for your Thoughts

That's correct, mixing or averaging sensors will be the way to go in the future.

Thanks, but I have a pretty good one that I use to check steam traps.

Why would you waste your time keeping those clowns happy? Lets get this straight, everything in the OU world deals with dangerous voltages or explosive gas. Every person should gauge there mechanical abilities and make a wise decisions on how to proceed.

How dangerous are the components in a powerful Tesla coil? Funny how they post on a forum call Overunity Research but nobody does any research? What exactly are those two building and researching?

You have the one guy using someones report to debunk Peter Davey's device. Then in the next breath he speaks of two unconfirmed variables. Well if there's still variables in the equation then I guess it hasn't been fully debunked.

He then goes on to say that you are wasting your time? Funny..... the professional community has debunked the free energy movement but those two clowns show up on a daily basis to research what........ overunity devices that according to there standards don't exist? ......Strange. you bet.

Please Please Please tell that knucklehead that nobody has said, spoken, written ANYTHING about the mains frequency being 480Hz or adjusting it to 480Hz. We are talking about acoustic tuning.

Not much Research at Overunity Research. All the good mechanics with build skills left. Within the last 3 months they lost about 100 members. All that's left are Walmart associates during the day and armchair theorists at night. Sad they have a No build No research attitude.

Very true
This device is an absolute walk in the park compared to "Most" of the things fellows Research.

I am having a really good time ! This is going to be fun to play with!!

Thanks Again

I saw also on the video's that a huge air bubble gets trapped under the first cup. There is no indication from Davey if that should be a vented cup.

And at the end of the day thats really what its all about. Eventually they will come to the conclusion that a Tesla coil, specifically the capacitors used, can kill you also. Hydrogen, can kill you also. If everything is dangerous and out of bounds what is there to research?

Always take the correct measures to build a safe device, handle capacitors correctly, vent your work area of Hydrogen. And also remember. Don't drink and drive.

Good Job Core!

Just an observation.
I did a lot of work with Stan Meyers idea to produce hydrogen from water.

Basically - 2 stainless steel pipes, 1 inside the other with a 1-2mm gap between them. Pulse with positive on 1 pipe and connect the other to negative. Produces hydrogen between the pipes. I'd lite the hydrogen bubbles for a loud pop to amaze the kids.

I understand you're water is getting hot fast where as my water wasn't even warm but could you be generating any hydrogen?

Like l said just an observation.

I'm pretty positive Don that there was some hydrogen. I did not confirm it but I would believe its a given with this type of device.

What voltage did you use?

Thanks for posting the video. For now the video just shows good old fashioned resistance heating. Some numbers for reference:

In your video you heat what appears to be an 8oz glass (1/2 lb) of water from ambient 66 to 200 degrees F in approx 134 seconds. (134 deg F rise delta)

At perfect efficency that would take approx. 528 joules x 134 seconds = 76032 joules energy.

Your meter says approx 4-5 amps x 120 volts = 600 watts/hr or 600 joules a second, 134 seconds x 600 joules/sec = 80400 joules.

That works out to approx 94-95 % efficient as of now. About the same as dropping nichrome resistance heaters at 120 v at 4-5 amps in the same glass of water.

Perhaps the glass is more than 8 oz, and the reference to amps consumed are not exact, but no OU yet.

I know your video wasn't for measuring purposes just yet, I'm just recommending for the future when you get the thing tuned.
After it is tuned, Try heating a larger known volume of water for say 5 - 10 minutes and get a rough reading of total energy/amps consumed (with one of those killawatt meters) and you can get a rough measurement of your units efficiency.


Good luck.

Good post, right now its all about getting comfortable with it and finding the best materials to work with. The SS cups are the first things I saw so I started with them. All adjustments are just make visually for now, from this you get some idea's of what will work better.

Yes, if performance with or without these materials gets better then more robust approach to measurements will be made. Paul mentioned stirring the fluid, that's a good idea. Averaging sensors my work or simply getting a bigger tank with a small low power pump.

Tuning

Tuning was interesting. Can home early and started tuning, In this case I mounted the bowl on the drill press by passing a 3/8" bolt through it. From here I used a sharpening stone with the press on. Steady pressure was used to remove material evenly on the cup.

Periodically I would stop and position it on its hanger to check tuning. Interesting, as I removed material ringing frequency dropped. I started at 400hz and ended up at 371hz. At this point the cup was pretty much paper thin.

This appears to a snag in these SS cups not much of a range can be obtained. I checked the other cups. With the lip on them they have a natural frequency of 1000hz or so.

I will probably keep tinkering with these cups I believe the forth octave of 60 Hz is 960. I'll try to tune a new cup to this frequency.
