Way back a long time ago, the backs of magazines used to sell plans for changing the power factor of appliances and even entire homes. The idea is to change the phase between alternating voltage and current so that it's measured incorrectly; exploiting the difference between sum(volts * amps) and sum(volts) * sum(amps). They used to be scams but it sounds like they could work now.
