Samsung Electronics has created a television remote control that does not require batteries, as it draws power by harvesting otherwise wasted energy emitted by wi-fi routers.
The South Korean consumer electronics giant originally launched the Eco Remote as a solar-powered device last year.
At the CES technology trade show in Las Vegas, the company unveiled a new version of the device that includes a tiny antenna that can capture Wi-Fi signals from a distance of up to 40 metres.
That allows it to charge even in dark rooms, the company said.
Samsung said the remote could prevent 99 million AAA batteries going to landfill over the next seven years.
“Disposable batteries are not the best for the environment,” a Samsung spokesman said. “The remote is made from recycled materials, making it even more eco-friendly.”
The company said it would include the remote control with new televisions and other home appliances.
