"It would be great if batteries could improve exponentially, à la Moore’s Law. But it’ll never happen. Gordon Moore himself told us so in his seminal 1965 magazine article, in which he predicted that we would be able to double the number of components in a digital..." (1/4)

"in a material, using a reversible mechanism so that we can tap that energy later. And because we pack that matter as full of energy as we can, halving the amount of matter halves the amount of energy we can store. No Moore’s Law. Not ever." (4/4)
