The problems will come when Li batteries are *really* popular for cars. There is nowhere near enough Li to supply even a fraction of the ultimate demand. Researchers might spend their timer more profitably looking at Al and Mg.
Who says battery technology can't keep up? With research like this concentrating on ways to boost existing lithium ion batteries, plus efforts elsewhere to craft lithium-air and more exotic formulations, I predict a bright future for battery technology. Will battery technology ever catch up to Moores Law? What do you think?
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
