PowerPot Turns Heat and Water into Electricity




U OF UTAH STUDENTS INVENT PORTABLE POT THAT DOUBLES AS A THERMOELECTRIC GENERATOR, RAISE $126K ON KICKSTARTER AND START SELLING PRODUCT AT NATIONAL RETAILERS

Power Practical, a student startup that sprang from research at the University of Utah, is selling a portable cook pot that transforms heat and water into a power source. Imagine charging your cellphone or using speakers in the mountains at night far from civilization. That’s what the device, called the PowerPot, can do with just a campfire and a little water. Using thermoelectricity, the PowerPot generates power by capturing the electrons moving from the heated pot to the cooler water inside. The greater the temperature difference, the more electricity is generated.

The company has a growing variety of PowerPots that serve different needs. The basic model, the PowerPot V, weighs less than a pound and produces 5 volts, enough to charge a cellphone in 60 to 90 minutes. Larger models, like the PowerPot X, produce 10 volts and can charge larger devices, like a tablet computer.
