Is Net-metering available where I live?

Net-metering is available to customers installing eligible energy production facilities throughout the FirstEnergy service territories. Each kWh of energy received from the customer offsets the energy delivered to the customer on a one for one basis, up to the amount of energy delivered to the customer during a billing period. Excess energy received from the customer is credited to the customer's account at the applicable generation component of the customer's rate schedule. See: http://www.puco.ohio.gov/PUCO/Consumer/Information.cfm?id=8510

  • Guess: This phrase above means you get compensated for the kWh charge but not the network distribution charge. – need to confirm / deny with Roger's friend or FirstEnergy

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.

Capacitor-Charge-Transfer-Schem

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?

LTSPICE NetList

I want LTSPICE or otherwise to put out a spice deck like netlist as shown in the photo inset and the video embedded below. 

 I have not yet found a way to get this type of output.  All the output formats you can select for export in LTSPICE have the form:

Node#1

RefDes1.Pin1, RefDes2.Pin1 …….

Node#2

RefDes1.Pin2

Which of course is suited to pcb layout programs but not what I am trying to do.   See ExpressPCB Netlist format.
