Do they have a magnet in them? If so - Could be based off the Mesmer principle.... also magnets on certain pressure points can be used to alleviate conditions etc... Chinese solders used to bleed kidney point one to help alleviate over heating so they could march all day...
Old is new again....

I just created my own imagination land

This was also a hot topic way back then.
from Wiki
"
Brock began publicly supporting and, eventually, began to fit to all Holden Dealer Team specials a device called the "Energy Polarizer" containing crystals and magnets that, it was claimed, improved the performance and handling of vehicles through "aligning the molecules".
The overwhelming majority of the Australian motoring community regarded the device as pseudoscience.[10] Brock also recommended tyre pressures of 22psi (150kPa) for his polariser-equipped vehicles, a level which many regarded as near-dangerously low. Holden, fearing the consequences of being associated with the device and a resulting breakdown in communications over Brock's plans for new models, cut ties with Brock and set up an alternative racing/modification operation, Holden Special Vehicles."

Barn,
You have so much faith in science, but what does humanity have left when science fails us?
....Some faith, hope or a bit of belief....It's not such a bad thing.
Your science is just another greedy industry out to make as much money as it can, if that wasn't the case things like cancer drugs and treatments would be free, but they choose to feed of the pain and suffering of others.
As for the rhino, it comes down to what we as individuals find acceptable and to be honest if one rhino horn could save a hundred people I would find that acceptable. It may not be right but I could live with that sacrifice.
We all ride around on carbon fibre which pound for pound while being constructed release toxic gases into the environment but we find this acceptable.
Your science has killed far more people and animals then my power band ever will....
as far as sailing skills went)
We have to apply scientific and engineering principles to these harmonic devices. Recall your Nyquist stability theorum. In some instances if a true harmonic stimulation is applied vibrations can lead to instability. Clearly Brocky had his device too finely tuned to the cars natural frequency resulting in a catastrophic case of instability. I think Muhamed Ali wears a highly tuned power band that leads to uncontrolled tremors. If these bands were precisely tuned to the individuals natural frequency we would see people starting to wave around like Peter Garrett before finally flailing their arms and legs off.....that would be indisputable evidence of the efficacy of the power band!!
you lost it and now your back to square one and learning how to stand on your board
OK, Thanks to science I've had my arms and legs re-attached and all is good.
As requested I've put the power balance band to the test today and the results speak for themselves. I've compared my session from yesterday with the band on to todays session without the band.
Thursdays session with the Power Balance band...
Date:.............07/10/2010
Boards:...........JP SLW 154L
Sails:............ NP Helium 8.5
Wind speed:....10-15knots
2 Sec:............22.2knots
5x10 Sec........20.52
Alpha 500.......13.39
Rider weight.....95kg
Awesome day on the water, blasting back and forth all day doing gybe after gybe, tack after tack in perfect balance.
Fridays session without the band...
Date:.............08/10/2010
Boards:...........JP FSW 112
Sails:............ NP ALPHA 6.2
Wind speed:....0 knots
2 Sec:............0.00 knots
5x10 Sec........0.00
Alpha 500.......0.00
Rider weight....98kg(a few beers last night)
Just couldn't get planning and kept falling off, My gybes were all very wobbly and I kept sinking the board in the tacks...Terrible day.
******My Scientific conclusion*******
Base on the results of this scientific test the Power balance band improved balance and also my power, My GPS files are available for any doubters out there.
Anyways I'm off to sacrifice a Panda as I've been told this will help me do forward loops....Now where did I put my snake oil...Oh there it is right next to my book on Scientology which happens to be under my ivory back scratcher....Oops I've just kicked over a bowl of ground up Rhinos horn because I tripped on a severed tigers penis.....I'm having a shocker, where did I put that power balance band.
Apparently this is a very old story (December last year)
The website/facebook page for the distributor both closed shop a while ago.
The bracelets are made in China for $1.17 and sold for $60.
There is no scientific proof, or any double-blind placebo tests performed on it.
This reminds me a bit of the book titled "The Secret" (see the Chaser sketch).
Cheers
