Solar-powered wireless keyboard
The Japanese company Buffalo introduced the BSKBW01SB wireless keyboard. In general, it is quite common, except for additional control buttons and a small rotatable panel above the digital unit - a solar battery - due to which the keyboard works.
Despite the fact that the energy produced by the solar battery is quite enough for the keyboard, it also provides for the presence of the usual "finger" batteries. They are needed to “launch” and establish communications, as well as to work in the dark.
The cost of BSKBW01SB is $ 120. The question arises: can it be better to change the batteries more often than to lay out a considerable amount for such a device? Although the "green" obviously will like.
