Tinsel must have his own institute to make replications so quickly.

This, btw, is not a Wimshurst machine. Wimshurst machine works by generating charges by moving the plates past each other. Interestingly there, the induction of charges by itself takes no energy, but moving charges in relation to each other takes energy. Testatika is a Wimshurst machine, but whether any elements of that device are also used in Testatika, i don't know.

I think if connect capacitor to sharp and flat conductors, capacitor will be charged.

If that's so simple, then why don't you try that?

The things which are too simple, it is questionable whether they work though. Why, because during the long history someone did already stumble upon them.
