STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[Omnibus]

Steorn do not eliminate back emf, they recover the energy of the back emf.
A simple circuit with a diode connecting the coil to a capacitor can recover the back emf energy when the current in the coil is switched off. For example, all switching power supplies recover back emf, it is conventional technics. Even beginners in electronics engineering know it. It is the same in motors, and it is the reason their efficency can go up to 95%.

Take a look at @Omega_0 calculation. That'll clarify the issue for you.

Hi All,

As the mechanics are bi-directional with timing the only issue as to rotational direction, the BEMF resulting when the coil/s are turned off ADDS to the rotation and hence efficiency.  Don't need to harvest it, it is already used if diode across the coil!!!!!!!  It is a moot issue.  Being married to two women (one after the other ha)  for 42 years and 4 kids has made me a verry mellow fellow.  Egos here/a persons competance/ slip ups, all part of life, don't mean "nuttin".  Ideas, theories, results, and HAVING FUN AND SAYING WOW WOW when you see something work and then trying to figure out why when the workings turn your "theoretical" world upsides down is where it is at!!!!!
ALL, keep up the good work!!  And whomever the pest is that keeps locking the site down, simply quit it.......

Respectfully
Ben

@Ossi,
well done !
Looking forward to see a few measurement numbers from you.
Nice enhancement with the iron washers !

Regards, Stefan.

Hi Stefan,

OK, here they are. Motor being powered from batteries via a 1 ohm shunt resistor. Voltage to motor after shunt is 2.2 volts. Average current on analogue ammeter is 300ma. Rotor is spining at 180 RPM. Circuit is a simple series circuit of battery, shunt, reed switch and coils, that's all. The two torroidal coils are in parallel. Here are the scope shots.

The first scope shot is across the shunt resistor. The second scope shot is across the coils (Both are in parallel).

Regards,

Ossie

Hi Ossie,

Can you also weigh out the rotor so that we can make Omega_0 calculation. It'll be very nice if Ben also does this. Thanks.

Hi Gang,

Does everyone realize that we have experimenters on every continent working on this now.  All are contributing in their own way to the effort to understand  this effect!!!!!  Absolutely most excellent!  The internet has made this possible, the rapid melding of minds and ideas.  Astonishing.  I stand in AWE.
