Glad you understand this enuff to assume and write things about presenter ?
7 years now ?
Please teach ...
or show us _your_ replication !


Too much pointing at others ....not enuff teaching/sharing!
Exactly what are you waiting for ?
Here it's an open source forum.
Schematics etc etc ?
Many open source builders here .
Please share !


Thanks
Chet
EDIT for comment on removal of " your personal surveillance info above"
And now modified you tube link you posted ?


Here opinions from  core members and reasons they
Moved on !

Perhaps best to show your own work ?


Enuff hauntings ...and assumptions about others ...

PLEASE share something ( anything) that can survive scrutiny and show a true gain mechanism...
Yes obviously you must have replicated video and have something which works to share ?
Please do share ..
Here we are part of open source community
Which greatly needs solutions !

ur right. my comment was just to inform regarding that vid I recently found.

Help me out here.
In my very limited understanding of the back EMF avenue to OU, do I understand correctly that in a perfectly efficient system with fully recovered back EMF, we'd have a COP = 2 system?
Now what efficiency might be realistically achieve in high power density solid state applications, around 95%?
Then would recovering about 15% of the available back EMF not already suffice to get a self runner with a few percent of net out, a never depleting battery that does real work, a few % of circuit flow?

Thinking in terms of equipment I read a lot about, electric cars. A Tesla car, especially the big ones, seem able to maintain about a 100 kW output (1 C discharge) for longer periods of time, at say 85-90% efficiency with battery is pre-charged.
If just a but of it's back EMF were to be recovered, this car would become a multiple kW OU station, right? Not enough to drive, but enough to provide the grid more than it would be pulling from the grid, over a typical annual usage.

I want OU to work, but if back EMF were a viable field, would we not have easily replicable setups with predictable net output by now? If someone could recover as much as 50% of the back EMF without hamper the regular output, that would turn a boring BEV into a huge power station and a total gold mine. Seems to me, if viable, a back EMF runner would be easier to build than a magnet more.

I think Joel's point (forgive me for putting words in your mouth Joel) is that we've only been able to tap 5% of the available back EMF and this proposed new way forward might unleash 10 times more (or more) by 'filling in the gaps' if you were.

I'm interested to see how far this can be taken. It doesn't seem to have been tried before in this way and bravo to Joel for having the imagination to see this possible route.
