Electrostatic precipitators are widely used. The equipment is expensive and expensive to operate. Industry won't use them unless they are required to. — T Clark
If they are indeed practical purely on an environmental and resourceful level, my next question will be; why is this technology not government sponsored? — XanderTheGrey
It's clear that my next objective is to examine the cost and range of use of electrostatic precipitators, objectively; so that we can define "widely used", "expensive" and or "cost & energy efficient". As well as the production cost in comparison to the "asking price". Basically I'm now only concerned with whether or not they are practical in of themselves, without considering monetary economic factors. — XanderTheGrey
