We've seen many impressive-looking PC mice and keyboards over the years. We've seen mice that support switching between different weights, keyboards with backlights and special keys, and more. At CES this week, Lenovo is unveiling a new mouse and keyboard combo that has another power source: the human hand.
Lenovo calls this combination a "mechanical energy harvesting combination" in a press release. Here, "mechanical energy" comes from humans. PCWorld revealed that the mouse has a handle on the bottom. After just turning it for a few minutes, this wireless mouse has enough power to last about 30 minutes.
Keyboards of the same series have more power supply methods. One is the solar panel on the top of the keyboard, which can help charge the keyboard. There is also a dial in the upper left corner of the keyboard. But it's not used to control volume. By rotating the turntable for about 5 minutes, the keyboard can be powered for 30 minutes.
This new mouse and keyboard concept is reminiscent of doomsday prophets who want to save as much power as possible before the end of the world. Their computer may need some power, but they can save a few watts by turning the handle, or use some solar energy on the keyboard.
PCWorld said that, of course, both mice and keyboards can use ordinary batteries. In terms of performance, the mouse has a built-in 12800DPI optical sensor, as well as two main buttons and two auxiliary buttons. The keyboard has RGB backlight effect. Both products can be connected to a computer via Bluetooth or the built-in USB adapter.
Lenovo said the products are just concepts for now, adding that they are designed "in line with Lenovo's commitment to implement more sustainable practices." It's unknown when or even if it will be produced in large quantities and sold to the public.
