University of Tokyo researchers have developed a machine to gather and recycle wasted energy produced by microwave ovens when they run. When cooking food, microwave ovens continuously lose energy that could be put to a better use.
The device has an antenna that collects the excess energy and distributes it to other devices. Engineer Yoshihiro Kawahara and his team found that running a microwave for two minutes generated enough energy to power a kitchen timer with small batteries for a few minutes. If the technology was built into kitchen applications, consumers would be able to decrease their carbon footprint with no extra effort.
