No ZPE here - conclude nothing! It is a simple trick. The ammeter is
measuring current at the water electrodes while voltage is taken at the
main input supply.

What happens is that as the rotor magnets are inductively coupled to the
output coils there is a magnetic flux linkage across the airgap between the
magnet and coil poles. When the pole gap is 'loose' (large gap), the flux
coupling becomes sensitive to the response time of the output coil. By
arranging the system so that the flux coupling frequency is higher that the
coil response time, there can be a decoupling effect between magnets and
coils. This simply means that, from the coils point of view, the magnet
poles race past too quickly for complete flux coupling to occur. When this
happens induction to the coil decreases (decreasing output power) and the
magnetic drag experienced by the rotor also decreases. Less drag means less
load which in turn allows the rotor to increase RPM.
