Dig this,
These guys are offering a power correction box for the home and claiming it will save you 25% on your utility bill. All it can do that benefits you is reduce the current between your meter and the pf box meaning a slight decrease in power lost due to the resistance of this wiring. They are running commercials on TV claiming to save the heat loss of motors and all kinds of ridiculous stuff.
If anyone knows of a way to get the word out to the public, now would be a good time.
