Back ElectroMotive Force or BEMF, is real and useful. Here is shown how it can be recovered very easily. It is energy that is discarded by current science. It can be used to do work. It can be used to increase present circuit efficiency. in Part 2, a simple technique will be demonstrated that that energy can be used to do real work.
I had to give you a like on this series of videos you made. With my current project I haven't done anything with my stored bemf except burn it off across a resistor. Work performed but not very useful at this point. If I don't run it across a load it accumulates up to 1200Vdc depending on what fet I use. In the future I plan to have it be the source for my HV experiment. I did that very successfully in the past. However unfortunately I have no vid to show for it because it was a beautiful sight. I had a rotor spinning at about 6k rpm. I then discharg5e the stored bemf across the rotor. I never reproduced it again. I won't bother with details as to why. The bottom line is that yes it is useful and you have demonstrated that well. I look forward to more.
The BEMF was used by everyone. but was never isolated. I was able to isolate it. Remove the battery and use just the BEMF to work the circuit. All with just a few flick of a switch.
I learned a lot. Replacing the switch with MOSFETs, triggering the circuit with an oscillator. Watching the BEMF increase or decrease while adjusting the frequency of the oscillator is a key. There is much more to it. That's the basis only. It is now clear that is real and useful, moreover wasted in most circuits.
Anyway, I digress. Thanks for your comments and interest Jim. BEMF is part of future development, that I'm making.
