This is Part 4 of The Ringer apparatus showing Overunity by utilizing Ground Energy via Negative Resistance and High Frequency.

This is a replication of the work done by MTech Industries from Youtube.

This is an apparatus named "The Ringer" that shows the effects of Negative Resistance, Ground Energy and Overunity when the device is properly tunned.

I am running the apparatus while charging the source and a second battery at the same time. It is extracting very little energy from the Ground but it is enough to charge the batteries while running.
