I noticed my tire shop is using what appears to be a rather low end web tool to manage their stock. This points out business opportunity.

Capacitor Charge Sharing
When reading about charge pumps you will encounter a phrase like "they act like resistors". The following example demonstrates why they say that.
So each capacitor ends up with 1/2 Volt on it. That means the system starts with 1/2 Joule of energy and when the transfer of charge is done total energy in the system is 1/4 Joule.
So what happened to the lost 1/4 joule? It got dissipated in the series resistor. What about if you do not use a resistor and just charge up C1 and connect it to C2?
