One of the benefits of flash memory is that it doesn’t require electricity to retain its contents. So why, then does this USB flash drive have a solar energy source?
The solar panel that’s built into the flash drive generates electricity — not for the flash memory, of course, but to run a clever LCD display. The display shows how much remaining capacity is available on the drive so that you don’t have to plug it into a computer to see the value.
It would be really cool if you could put a text file on the flash drive which would be displayed on the LCD, but for now, simply showing the free space is much better than the other display-less drives do!
Information is very sparse but I’d imagine you’ll start seeing these at the common online retailers pretty soon.
