Five physics lessons for Obama. Including: “If the [nuclear] waste is stored underground in such a way that there’s only a 10 percent chance that 10 percent of it will leak—which should be more than doable—the risk will be no worse than if we had never mined the uranium in the first place.”

Or how about: “What about high-quality batteries—the kind used in cellphones and laptops? These batteries contain only 1 percent of the energy of their equal weight in gasoline. You can recharge them cheaply, but current batteries typically die after 1,000 charges. If you include the cost of replacement, then they are far more expensive to use than gasoline, though a bit less harmful to our atmosphere.”

Worth a quick read.
