I first started thinking about thorium reactors after watching a TED talk by Kirk Sorenson. I found the idea of developing an alternative to uranium based reactors that was safer, smaller, cheaper, and that uses a more plentiful supply of fuel to be pretty mind bending.
More recently, Business insider published a long article about thorium reactors and I posted on it.
Since then, I have started to look for sources to keep up with news about thorium reactor development. I will be tracking these.
