Naturally I have to wonder how scalable this technology is. How much energy can be extracted from one of these diamond generators at a steady rate. Are we talking microwatt-hours, milliwatt-hours, watt-hours, or kilowatt-hours?
And, second, I have to wonder how many’eternal batteries we want out in the wild. How would you ever disable one of these if that were necessary?

Here’s an AMA session at Reddit about these batteries.
