Proven Overunity Heat from Transient Events in Water! (Video 16)

Two inventors (Karl Schaeffer and James L. Griggs) came up with two similar technologies, both based on the principle of using transient events in water ("water-hammer") to create overunity heat.
This video is one in a series intending to show that Free Energy has been produced by adding simple changes to commonly known technology, producing results which have been measured but largely ignored by the world.
What will we find if we follow the trail of these overlooked or suppressed scientific discoveries?
Stay tuned for future videos in this channel! And, in the meantime, please feel free to check out the following links:
