i've got a cheap $15 dollar form of cooling in front of me...a 12 inch oscilating fan.....i find one thing intersting...dust particles seem to be attracted to and stick to the fan blades...what about a product that causes dust particles to "stick" to a wood-type membrane?....i can imagine a spritz type water fan filter that glues dust particles to a wood-type sponge...this sponge/filter might be used for local/near-by air cleaning...or... it might be used for larger scale "scubbing" of the atmosphere
the moisture of lungs causes particulate matter/smoke to stick to lung walls......why not have a moist wood/water filter/sponge that sticks/attracts particles?....
Canada needs to think of new products for wood products...a wood filter/spoonge that cleans the air might be another product for trees (besides TP and paper)....locally/personally one might have a moist wood sponge/filter that sucks/sticks dust particles (most of heating and cooking in 3rd world homes is done by old-school stoves...(which means alot of local air dirt))....
not only could a wood-type filter/sponge clean air locally.....why not large scale?....imagine off the coast of NW Africa....floating blimps/ballons that house water spritzing, wood filter/sponges....how much dust particulate matter might those large scale scrubblers clean the atmosphere?....get rid of the seeds for future hurricanes
(more later...
