Update: One of my readers kindly provided a link with some very detailed technical information: http://www.overunity.com/index.php/topic,4047.240.html
In my original post:
I examine a device proposed by Thane Heins. He calls the device "Perepiteia" which deceptively echos of 'perpetual' when in fact it's from the Greek meaning "a sudden reversal of fortune". A kind poster on the original article pointed out that Heins appears to be applying power to the motor. Thus, this is NOT a claim of perpetual motion, nor can it be, given an external power source.
Just the same, the puzzle remains: Why does the device accelerate when the induction coil is shorted out? My personal question is: Does the device continually accelerate or only accelerate to a given point? If it continually accelerates we must examine the possibility that this configuration somehow has created free energy (highly unlikely with respect to current dogma). If it accelerates only to a given point, then the device is likely a new, more efficient, implementation of an induction motor (possible even in consideration of current dogma). The MIT professor who reviewed the set up refused to call it free energy or perpetual motion, but was willing to consider the set up a possibly more efficient induction motor.
I've dug a little deeper and dug out the actual patent application:
The patent application makes mention of superconducting coils and wires, yet in his videos where he demonstrates the apparatus, I see no evidence of them.
Digging a little deeper, I came across this post:
http://peswiki.com/index.php/Talk:Directory:Perepiteia_Generator_by_Potential_Difference_Inc#No_Useful_Output which suggests that Heins' design is more like a brake and the shorting out of the coil which produces the acceleration is really just a release of this brake. The relevant topic in dynamics is 'Hysteresis' and Heins's setup, appears to use this phenomenon as some sort of a electromagnetic brake. Shorting out the brake would of course lead to acceleration. The above poster also points out that in the 7th video, Heins has a large fan cooling the motor which suggests that this very well may be a brake since braking would cause the current to be released as heat.
I always root for the underdog, and the story of a college dropout who developed free energy would have made me smile. However, in this case, it looks like we'll have to wait to tell such a tale on a different occasion. Just the same, I wish Thane Heins the best of success and hope he continues his research and that significant findings result.
