  • An Industrial-Sized Generator That Runs on Waste Heat, Using No Fuel

    Startup Alphabet Energy has its first product: what it says is the world’s largest thermoelectric generator.

A new device could reduce that waste, cutting fuel consumption and carbon emissions by as much as 3 percent and saving companies millions of dollars. (Three percent might not seem like much, but for context, air travel accounts for 2 percent of worldwide carbon dioxide emissions.)
