It is always so frustrating to hear people saying that electric will never displace petrolium fuelled vehicles. The latest batch is just a taste of what is to come. Safer, faster, more stable, and quieter.
@Rick: now that I see the way Model-S mounts its batteries, I have to wonder how the idea of a battery switch station would work in this case? Could this have been one of the points of contention between Tesla and the now defunct Better Place?
Divakar - I've seen a video of the battery replacement process. It drops down. Tesla released a video showing the process being done in about 60 seconds. It's pretty impressive. I would have to imagine that in a real-world setting, it would take longer, but even at two or three times, it would still be very quick.
I have a FORD Escape Hybrid. It is also safer than the combustion engine version. One reason is that the weight of the batteries significantly lowers the center of gravity. I can drive steep mountain roads in say Yosemite with better traction and "feel" for the road.
It's nice to get a different connection between 'lithium ion' and 'safety'. Between fiery laptops, cellphones, and Boeing planes it was starting to feel like batteries would be classified as WMDs. At some point people might wonder about those crazy 20th-century drivers that carried a tankful of explosives in every car. It doesn't bode well for car-chase scenes in future action movies, though...
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
