Right a Watt-Hour meter treats reactive loads like resistive load - the
meter can't tell the difference. But the load of a large motor - like an AC
compressor - is mostly reactive (the resistance is negligible). If you can
vanish the reactive load, you get your AC for free. Supposedly.
Here's their website:

There's even a few on Ebay for about $270

I, for one, would welcome comments from those more knowledgeable than I.
