A while back I wrote about the coal ash ponds we have in the Triad that are similar to the pond in Tennessee that ended up bursting and flooding surrounding areas with all kinds of nasty gunk.  Well there's a story out out of Asheville about some residents in a subdivision who have a "cenosphere, a hollow, inert, nontoxic silicon particle that contains gas" that is blowing off a nearby coal ash pond and coating their roofs and cars.  Progress Energy, the owner of the pond, is working with North Carolina environmental officials to see how they can keep wind from blowing ash from their pond onto their neighbors.  Lovely.
