We covered Washington Governor Jay Inslee’s visit to the Group 14 Technologies battery plant in Woodinville last year.  Now the Group is getting attention from Porsche, among other funders.  The startup company announced raising $400 million from investors including the Teutonic automaker. According to Reuters, part of those funds will be used to build a second battery materials plant in eastern Washington State.  The company is now valued at over $1 billion, money which will help expand battery materials production for the silicon-lithium cell market. Silicon is a desirable material in batteries, capable of storing more energy than lithium or other metals.  It has a major drawback, though.  In expanding and contracting during charge-discharge cycles, it eventually deteriorates, crumbles, and brings the battery’s usefulness to an end. Dr. Yi Cui of Stanford University has tried various methods over the years to prevent such crumbling.  His firm, Amprius, has developed a silicon nanowire anode that enables a battery with 450 Watt-hour …

Since Chip Yates hit the fastest time ever for an electric motorcycle up Pikes Peak last year, then pulled the UQM motor from the bike and installed it in his Long-ESA (Electric Speed and Altitude) record-setting flying test vehicle this year, other Pikes Peak EVs have demonstrated the benefits of their high torque power units.  Such performance shows the ready applicability of electric motors, with their uncompromised performance at altitude, as being great for hill climbers or aircraft. Toyota, Mitsubishi, and several private individuals entered the 2012 Pikes Peak International Hill Climb, three finishing in the top 15 of all competitors. Scheduled for July, the hill climb had to be set back to August because of massive wild fires in the area. David Herron reported in Torque News, “The top electric finisher, Fumio Nutahara, driving the Toyota Motorsports Group EV P002 electric race car. The EV P002 is built on a Radical race car chassis, and has pair of axial flux electric …
