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

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
