Better filters for coal power plants if possible and if better to reduce smog and harmful air

Cleaner coal technology

Better filters are needed. 

Another idea: With a waterpipe design a lot of fine dust might be catched by the water. If possible. And if this is better.

Update: For the water pipe design: Maybe with ''bubble breakers'', with this a lot more will be catched. Or with extra filters inside the water. And research first if the passing of the smoke and everything with it through te water can give health problems.
And research how useful and effective it is to use this system.

Update: A problem: How to get all the smoke through the water if filtering with water is beneficial. Will it go through the water ?

Update: Offcourse not a single coal power plant would be even better.
