Battery technology is at about as far as it can go. It is one of the most mature technologies around. I wouldn’t get too excited about some wonderful breakthrough in this area. If something replaces the IC engine it won’t be soon, and it won’t be batteries.
I disagree. There is little or nothing designed by humans that cannot be improved upon.
I think I've heard something like that before. "256K of memory is as much as anyone will ever need."

For most users, rechargeable batteries have already replaced fossil fuels in weed-whackers, leaf-blowers, chainsaws, and increasingly in lawnmowers. Laptops and cell phones are built around their batteries. Rechargeable battery-powered machines are already winning; they just need more heft and longer endurance.
