Bessemer Venture Partners, which has offices in Wellesley Hills, MA, is the leader in a $30 million Series D financing round announced today for PowerGenix. The San Diego company makes rechargeable nickel-zinc batteries, which are lighter, smaller, and less toxic than batteries using competing chemistries, such as lithium ion and nickel-metal-hydride. Existing investors Advent International, Angeleno Group, Braemar Energy Ventures, Granite Ventures, OnPoint Technologies and Technology Partners also participated in the round, which will help the battery maker expand into markets such power tools, lawn and garden tools, military vehicles, light electric vehicles such as golf carts, and consumer AA batteries.

Between 2007 and 2014, I was a staff editor for Xconomy in Boston and San Francisco.
Since 2008 I've been writing a weekly opinion/review column called VOX: The Voice of Xperience. (From 2008 to 2013 the column was known as World Wide Wade.)
I've been writing about science and technology professionally since 1994. Before joining Xconomy in 2007, I was a staff member at MIT’s Technology Review from 2001 to 2006, serving as senior editor, San Francisco bureau chief, and executive editor of TechnologyReview.com. Before that, I was the Boston bureau reporter for Science, managing editor of supercomputing publications at NASA Ames Research Center, and Web editor at e-book pioneer NuvoMedia.
I have a B.A. in the history of science from Harvard College and a PhD in the history and social study of science and technology from MIT. I've published articles in Science, Technology Review, IEEE Spectrum, Encyclopaedia Brittanica, Technology and Culture, Alaska Airlines Magazine, and World Business, and I've been a guest of NPR, CNN, CNBC, NECN, WGBH and the PBS NewsHour. I'm a frequent conference participant and enjoy opportunities to moderate panel discussions and on-stage chats.
