You're willfully releasing pollutants into the atmosphere to see what happens, and hoping something good will come of it.

I very very much doubt this can't be shut down by some environmental agency, if they only care to look. Even if there is no specific law about it, you can't normally just release stuff into the shared environment - you have to have some kind of dispensation for it (like the oil and coal industries unfortunately have for their own pollution, for example).
