Another enjoyable post from you. The fog harp is an interesting invention but I find many of the comments worried about the potential damage from the device even more interesting. Does a hiker taking a sip of water from a river also cause them alarm? If we planted a tree or a bunch of trees and put a water collection system under them, would they still be worried about upsetting the environmental balance? We should always be mindful of the unintended consequences of our actions, but this fear of using technology to improve peoples lives is interesting to say the least. Just my opinion.
