We can tell things are heating up in the electric aircraft marketplace.  Established aircraft companies are investing (Boeing and Airbus for starters), growing numbers are planning for electrified and autonomous future flight (Uber Elevate Summit), and an absolute plethora of new designs are tumbling forth from an aeronautical cornucopia.  Their video of an Uber sky taxi ride illustrates the charm of the idea. A Common Reference Uber provided two common reference eVTOL (electric vertical takeoff and landing) reference models for partners to emulate.  Both seem to share a common passenger pod with an unusually long tail boom. Perhaps taking the 2011 Green Flight Challenge as his reference point, Mark Moore explained how Uber inspires others to give their best efforts to create several plausible vehicles.  The American Institute of Aeronautics and Astronautics (AIAA) reports, “’We will never build a vehicle, but we want to make sure that our partners who are building vehicles are successful and that these aircraft are …

Will VW Take on Tesla?

Volkswagen just bought a five-percent stake in a startup company called QuantumScape, a commercial spinoff of work done at Stanford University’s Nanoscale Prototyping Laboratory for Energy Conversion and Storage.  The Labroratory’s head, Fritz B. Prinz, Finmeccanica Professor of Engineering and Robert Bosch Chairman of Mechanical Engineering, explains: “Our team creates, models, and prototypes nanoscale structures to understand the physics of electrical energy conversion and storage. We are exploring the relation between size, composition, and the kinetics of charge transfer. We are also interested in learning from nature, in particular by studying the electron transport chain in plant cells.” (Note that the QuantumScape web site is curiously without detail, showing only four pretty pictures and making three or four non-controversial statements.  The most information comes on the Contact link.) Whatever they are doing, the Lab has caught the interest of not only Volkswagen’s CEO Martin Winterkorn, but produced a flood of often speculative articles from Bloomberg, EV World and other sources, …
