Here is more on these types of machines from wikipedia

In a Wimshurst machine, the two insulated discs and their metal sectors rotate in opposite directions passing the crossed metal neutralizer bars and their brushes. An imbalance of charges is induced, amplified, and collected by two pairs of metal combs with points placed near the surfaces of each disk. These collectors are mounted on insulating supports and connected to the output terminals. The positive feedback increases the accumulating charges exponentially until the dielectric breakdown voltage of the air is reached and an electric spark jumps across the gap.

Here is also an inqusitive comment by Rob The Plumber:

Awesome. Love the idea. I had a conversation with a friend the other day. We talked about why there has been no technology leaps in electricity. We actually talked about Tesla’s wireless electricity. I sure hope you can figure out the receiving tower. The fact that you are doing this for all of YouTube is a blessing to all. Thanks again.

These types of questions often come up when researching new efficient energy methods.  We hope you like the video.
