This image was lost some time after publication, but you can still view it here.

We don't know where this came from, but reader Tor sent in this picture of a solar-powered visor fan. It looks like the power of the sun gives life to the fan, which blows directly into your eyes, trading one type of eye discomfort for another. Even if this is real, despite the taken-in-the-80s look of the picture, we don't know where you can get it.

Thanks Tor!
