Peter Davey Heater

[AlanA]

Hi FatBird,

sounds logic. But Peter Davey seems to heat a great amount of water.

Hi FatBird,

Vaporizer. Interesting.
Could you give us any picture?

Best

I hope some more people will experiment with it,
as the most energy is still used in a household to heat
water via electricity.

To goo OFFGRID we need a technology like this to save
for instance the battery bank in your house ( if you
now use solar power or any other means to recharge your lead acid
battery bank..)
to heat water more efficiently...

So did anybody experiment with it already ?

Many thanks.

Regards, Stefan.

The Davey setup is definitely a good design, but we still have no idea of how much energy he is using to create the effect.

We know that Thrapp's setup seems much better, but is a bit more complex in its apparent use of multiple frequencies and a perfect sphere.

Little do many know, but there is another electric setup that I FEEL works better than both of those, and it was made by good old Stan, SM...

If you want me to write up a bit about it, let me know.

The answer is seen in any stringed instrument, or tuning fork. For example, take 2 tuning forks of the same LENGTH and hit just one of them. Put that vibrating one near the other and the second one will start to vibrate also. You can also use a tuning fork of double the frequency and get the same effect. Take a guitar and strike the low E string (top string) without touching the others. Now stop the string you just stuck and listen to the high E (thinnest string) and it will be vibrating also even though it is at twice the frequency of the low E that you struck. Octaves (doubling or halving of the frequency demonstrates this the best. Take a wind chime and another wind chime exactly half the length of the first. Strike the bigger one and then put it near the one half it's length and then stop the big one from vibrating. The smaller one will be vibrating also even though it was never physically touched. All the same principle.

In this heater the electricity (mains) are oscillating at 50Hz. These bells Peter uses can't be 50Hz because they are too small. I guess them to be 800Hz or 1600Hz which are just octaves of 50Hz.

Someone here asked how to tune bells. Just like wind chimes, the smaller the bell the higher the frequency so start with something a little lower frequency than 1600Hz and then grind it down until you get to 1600Hz. If using 60Hz mains then the bells would need to be 1920Hz.

Then these bells will be vibrating in octave relation with the mains and you just need to adjust the distance between the two bells to find the sweet spot where the waves coming off each bell strike the other bell so as to not dampen IT'S vibration.

Same theory as to why you suspend a wind chime from a particular distance from the end so you hold it only on the node of the wave so you don't dampen the wave that is traveling up and down the wind chime.

Or think of it like two children swings but slow it down to visualize it. A swing (pendulum) will have a natural frequency determined by it's length. If you want to use the most minimal energy to continue the swing swinging then you need to push at the same frequency as this natural frequency of the swing.

With the 2 bells vibrating both at 1600Hz (in the case of 50Hz mains) and distanced from each other so the node of the waves strikes the opposite bell at exactly the right time and you make the water very hot very fast :-)
