Tomorrows World long ago.......

[AlanM]

Once upon a time there was a programme called TW. One day they had an item about a water heater which essentially was a drum which contained a cylinder. The cylinder had dimples on its surface. Water was passed through the drum from one end to the other while the cylinder was spun. Apparently the water came out having been heated up, with more heat energy in the water than the energy supplied to the motor spinning the cylinder.
Does any one remember the above item.
I do understand that energy cannot be created, only transformed. The inference was that the water heating up was due to the friction/turbulence between the dimples and the source was zero point energy. There was a working example which was used for water heating in a fire station

Does anyone else remember this, or have any thoughts.
I await the enslaught.........

I fondly remember Tomorrow's World, but can't remember that particular experiment - "zero point energy" has been cited in several "perpetual motion" scams - here's a learned dissertation on the subject
http://www.calphysics.org/zpe.html  -I will confess to having got an acute dose of "tilt" on first reading - it seems rather reminiscent of the obscure concepts in banking derivatives............

Just noticed that this was a topic started by Amy in April, in general discussion, "Did any one see this"

This is probably the only story I remember from Tomorrows World.
I was a wee lad at the time, no idea why that one stuck in my head :-)

It would be nice if this stuff was cheap....

All our insulation problems would disappear.

Especially if it could be sprayed.

Apparently it's cut with a water jet!  http://en.wikipedia.org/wiki/Water_jet_cutter, how often do you have to change the working tips on these machines?

I think this maybe what you are thinking about.

Yes, heating water by squirting it through small holes is viable (friction),but it uses as much energy as it creates in the form of steam. Over-unity doesn't exist.

Wyleu, I looked at the Wiki article - I loved the picture captioned 'A water jet cutter creating a specialist tool' - showing a waterjet cutting out a template of an open-ended spanner!!

Sonic boilers are not new. James Griggs invented the hydrosonic pump.

You can buy one. Many claim it is an over-unity device.  I always looked at the Griggs Hydrosonic pump and thought the efficiency could rise if the motor was in the water flow giving up its heat to the water.  The same for any heating water pump really.  Some pumps get really hot and this heat is wasted.  Then maybe over unity.

The company:

They are also on sale in Moldavia for domestic use - where they were developed entirely separately from Griggs in the USA. 

I would like to see hydrosonic pumps developed further.  They can only get more efficient.  Large boiler companies like Viessmann and Vaillant need to invest in it.  A domestic unit would be nice.  They are quite simple and no scale build up either.  Then no gas meter and standing gas charge either.

Jim Griggs did not claim over-unity. He didn't know initially if it was or not.  He may have thought it was, but did not want to be regarded as a crank and be discredited before it was even off the ground.  The Moldavian unit was tested by NASA and proved not to be over unity.  However many in Moldavia say it is as when installed replacing resistance heating, the electric bills dropped substantially.

Water jet cutters are pretty standard and there are cavitation jets as well, as the wikipedia article briefly mentions.

There's also cavitation fusion http://en.wikipedia.org/wiki/Bubble_fusion  Perhaps that explains the perpetual motion claims      

If I buy a zero-point module, do I get a free Teyla? More likely a free Rodney, I guess 

[Ivan]

Cavitation fusion sounds perfectly viable - shame the guy can't be left to justify his work rather than his integrity

With further research I always thought a hydrosonic pump could be used as an instant water water.  A flow switch and the pump comes in.  No scale created.  Maybe a small vessel as a buffer and of course a good control system that maybe modulates the motor to the DHW setpoint.
