Comment: Re:That's mostly just the US. (Score 1) 786 786

RyanFenton: the use of various techniques to discredit aspects of science that suggested companies had to change their behavior began in the 1950's. For example, denying that smoking harmed health. Denying that chemicals were poisoning birds. For the details see "Merchants of Doubt" by Oreskes and Conway.

Comment: backyard light (Score 1) 243 243

Currently using an inexpensive single-led backyard white light. 6 inch square solar panel. Small battery hidden somewhere inside. Stays astonishingly bright all night illuminating a rose tree (pointing a bit down, not up at the sky). Way more than enough to read by. Something to free much of the world from darkness.
