Tesla device
I see advertised a device invented by Tesla that cuts your electric bill. Can't seem to find any info on this.

Yeah! The only voltage that you usually use is the top 10% of the waveform above 100 volts. All that voltage between 0 and 100 volts just wastes current and runs up your bill. So, the ideal device turns on as the waveform passes thru 100 volts on the way up and turns off at 100 volts when the waveform is on the way down. That way you are only using the most powerful portion of the waveform. When I get it perfected, I'll let you know. :)

My smart meter has a digital display. Yes it can be read by anyone.
Easier to use the electric company website that gives a daily tally, graph of usage by the hour and estimate for the next bill.

What happens is more current is drawn through wiring as the power factor drops below 1.0. Power utility companies charge commercial/industrial users for low power factor by reading KVA, KVAH & KVAR because it means they have to oversize supply conductors which gets expensive. Engineers and electricians make every attempt to keep PF close to 1.0 to avoid having to oversize supply wiring to equipment in buildings. And no discussion on power factor is complete without including "real power" and "imaginary power" and also leading and lagging PF. :D
IF you see a label with "Volt-Amps" printed on it, That means Volts times Amps, this is what you pay for.. Volts Times Amps, Times POWER FACTOR, is what you get. So bringing the power factor closer to 1.0, means you use less power.

Electric meters are my life and I can tell you that if you have a "Smart Meter" on your house, playing games with the power Co is over for you. What that meter can tell the power co is really everything. Stealing power is really serious and it can cost you big time. If you have a fire, count on your ins co to look into it. As far as reactive power goes, residential single phase has little affect on the bill, big 3 phase it does. The killer for us domestic rate people will be when TOU (time of use) hits us. I know, this is TMI.
