No it's not a claim, certainly not a promise, sorry. I heard it exists, tell me if I'm right.

Its a power inverter, you switch the amount of power you use from 220v to 110v or w/e. No, not the inverter you plug into your car to charge your cellphone or laptop. Appearently, it causes appliances to work more efficiently, utilizing a lower voltage source. How does it work? You got me. Does it exist? I think so. Somewhere, for some lofty price. Can we find it? Thats what I'd like to know. Let's get started people! This...could be revolutionary.
