Over at theBulletinoftheAtomicScientists, Pavel Podvig has a very interesting post about the mythology of missile defense and how it has wrongly been credited with ending the Cold War.
An interview published last year in theBulletinofAtomicScientists detailed how at age 88, he was working on a new approach to photovoltaic thin-film production that he said would allow factories to make enough solar panels in a year to produce at least one gigawatt of electricity annually roughly the scale of a nuclear power plant at the price of coal.
