If the minimum batteries are installed in electric cars and you just rented an additional extension pack for long trips this would make the cars cheaper up front exellerating sales.
this does a few things:
1) increases sales of e vehicles toward criticcal mass.
2)Lowers price tag (badly needed)
3)rent extenders as needed. (Could give 2 free weeks a year of battery rental as part of car purchase.
3)Allows for improvements in batteries to be rolled out and used instead of purchasing a new car with new technology.
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.
