Moore's law has provided us with dramatic improvements in CPUs, memory, hard disks, etc, but has had little impact on batteries. While the iPad has great battery life, this is due mostly to being almost all battery internally.
Louis Bergeron reporting … Stanford develops new batteries:
Stanford researchers have used nanoparticles of a copper compound to develop a high-power battery electrode that is so inexpensive to make, so efficient and so durable that it could be used to build batteries big enough for economical large-scale energy storage on the electrical grid – something researchers have sought for years.
