Aluminum-air also differs from lithium-ion in that it is not rechargeable. That's why the company is suggesting that its batteries be used in a hybrid arrangement, in which drivers would employ lithium-ion on a daily commuting basis, while aluminum-air would serve only on those days when greater range is needed. In such an arrangement, the aluminum-air system would last about a year before needing to be "refurbished" at an unknown cost.
So, great, you're carrying around extra weight every day hoping you'll not need it instead of driving a lighter car with more daily range.
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.
