Idle power control – phase 2 complete

So phase 2 of the idle power consumption testing is complete, and with some surprising results. It seems that the X10 appliance module didn’t consume hardly any electricity going by the Kill-a-watt numbers. Unfortunately the time measurements aren’t exactly the same, but they are close enough to get a fairly conclusive result.

phase 1 test results (XBox plugged into an outlet):
Test hours = 172
kW used = 0.30

phase 2 results (XBox plugged into an X10 module):
Test hours = 168
kW used = 0.30

If I had let the test run another 4.5 hours to mimic the phase 1 test then it *might* have added another 0.01 or 0.02 kW maximum. So the overall consumption of the X10 module is actually, and surprisingly, negligible.

Phase 3 will involve the XBox plugged into the X10 module, and the module will be turned off for several hours a day to see how much electricity is actually conserved. It is starting to look like it will be more than I initially expected, at least going by the phase 2 results.
