re: Does Tesla's Supercharger answer the road trip question for EVs?

This doesn't really scale. Imagine 1000s of electric cars driving from San Francisco to Los Angeles. They would all have to stop at the one station at Harris Ranch. If it is like the picture shown, there might be just four charging stations. So the wait is going to be a heck of a lot longer than 30 minutes. These Tesla cars and stations seem more of a solution for a handful of wealthy electric-car hobbyists. I don't really mind, because if they ever do come out with cheap battery or super capacitor technology that allows for -affordable- 300 mile plus cars, then it is useful to have our wealthy friends spend their money helping develop the required infrastructure.

@Bert- fair points, especially about the long lines that would form for 30-minute charges if EVs were really popular. But about the grid, Tesla says the solar-powered Superchargers actually give more back to the grid than it will take to charge the cars.

I wonder what it does to battery life, to attempt these high-current charging sessions. Anyway, sorry, this idea still relies on batteries, still requires way more "fueling" stops than the competition, and each stop is still way longer than anyone would accept in a gasoline powered car. Which means, among other things, that *if* BEVs ever did become somewhat popular, you'd have really long qeues behind each one of these stations. Still puts a heavy burden on the electric grid (assuming popularity of BEVs), and still limits people who want to get off the heavily beaten path. The answer has to be with fuel cells and on-board H2 separators.

I want to like electric vehicles for road trips, but this still comes up a bit short for me. A gas fill up is no more than 10 minutes even with a bathroom break and snack binge. When I'm on the road, I tend to be very impatient to get where I'm going, especially on long trips. I can't see myself fidgeting impatiently for 20 extra minutes every time I need a charge. It would be mental torture. Also, no option of wandering off the beaten path for for an occasional scenic view along the way would also make a long trip less enjoyable. Such spontaneity is useful for breaking up the monotony of long trips. Nevertheless, it's still a step in the right direction, and for trips that only require a single recharge, it would at least be tolerable.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
