Indeed, we will have crossed a major threshold when EVs can generate their required electricity on board.
What we need is Dr. Emmett Brown's futuristic DeLorean that was powered by a "Mr. Fusion" reactor that ran on banana peels and other organic matter :)
It's not such a futuristic concept, though. You can separate out the H2 from a hydrocarbon fuel, like gasoline or E85 or whatever, on board. And then you feed that H2 to a fuel cell on board, and the electricity to electric motors.
You can do an online search and see that people are working on just this sort of scheme.
Since fuel cells have a hatd time with generating high current bursts of energy, a hybrid-sized battery is probably needed too.
Everyone is talking about EVs and HEVs, but Stop-Start vehicles provide a good interim means to save fuel and reduce emissions. We at CAP-XX agree that Stop-Start vehicles – with potentially more than 100 starts per day – could quickly kill a standard lead-acid battery in less than 18 months. Supercapacitors can support vehicle batteries by supplying the peak current (300A plus) for each engine start, enabling longer battery life. Check our site for tests we ran on batteries supported by supercapacitors vs batteries alone: Slides 3 – 9: http://www.cap-xx.com/resources/docs/CAP-XX%20-%20Supercapacitors%20for%20Automotive%20Applications%20%28website%29.pdf
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.
