If anyone is interested, here is the third part of the series where the student claims to have built a perpetual motion machine.

There are lots of physical laws. Some, if considered on their own, seem to suggest perpetual motion machines are possible. Others, however, cannot be ignored and destroy any attempt to create a practical machine that generates equal to or more energy than it spends. Some examples are frictional heating (for mechanical work) and Lenz's law (for electromagnetism).
