Even as Nashville burnishes its tech reputation — see Oracle’s 8,500-job commitment as the latest example — Silicon Valley investors have asked Enexor BioEnergy CEO Lee Jestings why his company is in Middle Tennessee. He has described the region as an optimal place to do business and build a team, and the proof is in the pudding.

“We’re sort of on a winning streak,” Jestings told the Home Page of his renewable energy startup, which markets the Bio-CHP system, a shipping container retrofitted with motors, valves, fans, pumps, ignitors, proprietary turbines and a digital interface to convert organic and plastic waste into energy on site. A Bio-CHP installation can generate 75 kW of electric power and 125 kW of thermal energy. Executives say the units can offset as much as 2,200 carbon dioxide-equivalent tons annually.
