> here we are still with lithium ion in practice Lithium ion batteries are actually amazing tech. I certainly remember the world without them; laptops had an hour of battery life, mobile phones were "car phones", everyone was running around paranoid about the "memory effect", and electric cars were an interesting curiosity always ten years away. Here we are today with pocket computers that last for days and electric cars buzzing around the city. In 30 years, some of this new tech we read about will be widely adopted, but in the meantime, it's not like things are that bad. I think that electric airplanes will be the thing that new battery technology unlocks.
