Quite an explosion if a 1 kg battery developed a mechanical cascade failure and released its 1 MJ in a few milliseconds. That's about the equivalent of 250g of TNT - approximately 5 hand grenades worth.
If this concept pans out, that means that ceramic vacuum tube batteries could also end up being extremely rugged. As long as the final sealing of the ceramic didn't turn out to be a problem with the heat. This could circumvented by maybe sealing it with a laser.
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.
