With Andy Campanella, Sims formed a company, Loci Controls, that targets the nation’s 645 energy-producing landfills. The company created algorithms that adjust vacuum pressure at individual wells. Their system remotely monitors dozens of wells in real time. The initial results are impressive: One test site showed a 25 percent increase in energy production. Loci’s monitoring is also wireless, solar-powered, and user-friendly. “I check on the system on my cellphone,” says Sims.
