Gravity wheel of Krstan Pejic. This device works

[Shokac]

Hi All,

In the video he mentions his first prototype which is briefly shown @ 2:27. I think this would give a better idea of pulley ratio since it looks like all bike rims are being used.

These are just estimates on the bike wheels from standard sizes which they seem closest too.

Flywheel - 26" diameter
To Alternator - 20" diameter
The small pulleys look to be 1-2" diameter
Drive Motor - 16-18" looks a little smaller than the 20" diameter

Windshield wiper motor is between 30-100rpm depending on voltage, it has high torque since it's wound almost like a winch motor.

Let's go with 40rpm as an example

40rpm @ 18" wheel to 2" pulley = 40*(18/2) = 360 rpm on flywheel shaft
360rpm @ 20" wheel to 2" pulley on alternator = 360*(20/2) = 3600rpm

Please correct if you see a mistake.

Weight has on the other side.
Drive Motor - is from old waschmaschine fi 310 or 12,2"

He said it can ran for as long as batterys life - a few years

Why does it need a battery at all, after starting?

Please explain this, before measuring wheels and calculating belt lengths. Require a demonstration of the device operating without the battery. If this cannot be done.... please give some coherent explanation why not. I am quite certain that I or any other competent electrician could make the device self-charge a capacitor bank or use some other system to substitute for the battery -- IF it was actually making any excess energy at all.

I just translated what the inventor said in the video.

He said that the battery must be connected non stop so the circuit is not interrupted. He also said that 20 pct of flywheel energy goes to maintain the flywheel movement and battery recharge and 80 pct is used to power different loads. He also said that the battery is needed only to start the device.

That is all. I can not say if it works and if it does I do not know how for sure.

I see. SO
The battery is only needed to start the device.....
but...
The battery must remain connected non stop so the circuit is not interrupted.

Guess what.... the battery in my car is only needed to start the car....
AND...
Since it is only needed to start the car..... it can be removed once the car is started, because the car DOES NOT RUN ON THE BATTERY.


These "qmogens" are just bait. Don't be a fish.
