Sapphire Energy has tried to maintain a relatively low profile since it established its headquarters in San Diego—especially since last fall when the media seized on reports that Bill Gates’ Cascade Investment had joined a $100 million secondary round of venture funding for the algae biofuels startup.
So when Sapphire opened its San Diego headquarters for a public tour during the Algae Biomass Summit that was held here earlier this month, I jumped at the opportunity. The venture-backed company maintains a 70,000-square-foot facility on La Jolla’s Torrey Pines Mesa, and now has about 120 employees. The company’s labs look like a lot of other biotech labs in San Diego, aside from all the gyrating machines with flasks full of gently swirling emerald-green fluid. But there were two particularly interesting factoids about Sapphire that I learned during the tour.
