From Vice’s Motherboard and my friend Alex Pasternack, here is a great short documentary on an alternative nuclear energy model that many interviewed believe would have safety and economic benefits. Moving from a uranium and plutonium fuel cycle to one based on thorium, they say, would produce reactors whose failure state would be a safe one. The doc is a sympathetic view of folks who may look like cranks—but what’s to say they’re not on to something?*

*I have literally no idea whether this would work. As your local nuclear physicist.

At Motherboard.tv, Alex Pasternack and I took a look at the U.S. cyber offensive, one that’s far more secret but seems to match its worries about defense in scale.

I think it’s worth checking out.
