@All,

This is my first posting to this thread at this forum.
Heartfelt congratulations to all contributors on exceeding average posts >1000/month. A very active research group with significant developmental results. I also admire the group social self-regulation.
In my opinion, there is a fundamental thread undertone of curiosity and pure research; few are concerned with illusions of personal gain. There is an undertone of curioisty and rare alruistic research. 

@Bill
Will you drop an email to say hi at Alternative Systems Research Fund (ASRF@bellsouth.net) so we can discuss some things without cluttering the forum? I think you may be interested or I wouldn't waste our time.

@ All:

Have a look at the above video.  This fellow says that we can double the amount of back emf by using a few tricks.  This may well apply to our research here.  Check out his other videos as well because he explains how this works.  See what you think and let me know.  Thanks.  http://www.youtube.com/watch?v=zP4dfxXhxxg&feature=channel  This video, he charges 4 batteries with only 2 batteries.
