Pinnacle Looks Beyond Detroit as the Market for Its Opposed-Piston Engine

leave the venture world, where he’d been consulting with NEA and several other firms, and jump back into management to help Cleeves build Pinnacle Engines.

“If you are going to make a real, fundamental difference in the next 20 to 30 years, you have got to deal with fossil fuel demand,” Hoge says. “I see the size of the problem as an engineer and I also see the challenge of incremental thinking—big, structured companies using 50-year-old technologies. Real invention comes from somebody outside with a passion, who’s not mired in the traditional thinking. That’s Monty.”

Of course, internal combustion itself is about as traditional as it comes. The problem is that alternatives like battery-powered electric vehicles don’t match the performance of gas-powered cars, and are still far too expensive for mass adoption. It’s only by rethinking the old spark-ignition engine that vehicle makers will be able to raise fuel economy while at the same time moving away from petroleum-based fuels, Cleeves argues.

“This engine has the capability to ease the transition from fossil fuels to bio-derived fuels,” he says. “The energy density of alcohol is so poor [compared to gasoline] that right now it has to subsidized. The variable compression ratio mechanism allows us to pull some of the efficiency out of alcohol that you wouldn’t get in a traditional engine. So you can have much greater fuel economy as the price point for alcohol goes higher.”

Cleeves and Hoge say Pinnacle’s next goal, after the scooter deal, would be to try the engine in a light commercial vehicle such as an auto rickshaw (known in popular parlance as a tuk-tuk), and then to continue “blocking and tackling,” as Hoge puts it, until the engine is ready to put into an actual car. “We are funded and we have proof points, but it’s not nearly at the point where we’ve got an engine that we can hand to an auto manufacturer,” he says. “The longer we can go independently, the better the deals we could structure. 2012 will be an active year. I’m very confident we will find a lot of interest.” Just not in Detroit.

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.
