Gas-powered cars are extremely inefficient. Their engines only use a quarter of the fuel’s energy to turn the wheels, the rest wasted as heat and released via an exhaust pipe. A new inexpensive device could recover some of that. Attached to a car’s exhaust pipe, the device—an inexpensive thermoelectric generator—could convert the heat into electricity and use it in the vehicle, making the car more fuel-efficient. The device produced a maximum output of 40 Watts, enough for low-power applications such as phone-charging.
