Salt Lamps Suck The Chi Out Of Your House?

So I just read a quick article on using Crystals for Feng Shui. The article takes a swipe at Salt Lamps saying that though they look like Crystals, they are not like them at all and that using them can suck the Chi Energy out of everything and everyone living in your house.

This seems to contradict everything I have read about Salt Lamps and Feng Shui. Anyone got an opinion on this they want to share...assuming you haven't had your Chi already sucked out!
