A new system was designed to turn waste heat from chimneys into electricity. It has three parts: a heat collector, a power generator, and a heat dissipation module. The system directly converts leftover heat into electrical energy. By doing this, it stops a lot of waste heat from going into the air, which helps reduce the greenhouse effect. The researchers measured the voltage and resistance to make sure the system works well. This design lets us reuse waste heat from boiler chimneys, which is good for the environment.
