It's a scam. TANSTAAFL.
ZPE is an acronym for the same thing as BS. It used to be marketed as "perpetual motion machine" in the past. But just like in the case of "Intelligent Design" which sounds so much better than "Creationism", they changed the label. Too many people had found out that what came in the can was rancid. So now they are selling their stale merchandise under a new brand name. And people are buying again.
