Power usage saver

When you plug in a ac wall adapter, it drain lots of power when it's not even hooked up to anything, a transformer is a copper wire coiled around a core with little of resistance including the copper resistance and inductance reactance resistance, not much. This save power when there's no output(0.000000Amps). Turn the SPST switch on for power. The LED is the load.

All that heavy power is not count by ur energy meter unles u have industrial grade power delivery contract signed with local electric company. Meters are so constructed to not count any form of reactive power no mater how high it is (ten amps will stuff ur wires yet meter will not react and if it will catch only some minute active power losses that generate winding wire resistance and eddy curents in core. Hysteresy loses are nonimportant just a dust particle hardly to be even noticed unles u not operate at high frequencies)

Ofcoz i hqve in mind ordinary civilian end user. As i notice industrial grade endusers must pay for reactive power if it exceed monthly limit so there a cap compensation stations have high priority and trully save ur money. (Especially if ur monthly bill hits over one milion $$$ hehe)

I like this, the concept is nice

In the United States all residential power is charged on amp's draw, not voltages. This means 120v or 240v is charged the same.

So at that point we should use 240 at the same amperage for twice wattage? I'm pretty sure they charge by the kW/Hr, so that it's the same if you use 100W 120 or 100W 240
