Has any eReader ever had a Solar Cell? Is that practical? I mean would a reasonably sized (and priced) solar cell panel run an eReader?
Here is a solar powered kindle touch (k5): https://www.mobileread.com/forums/sho...d.php?t=182872

Of course, this one is DIY, but if you have any hardware geek friends, you can have one!

Also, you can buy USB solar chargers from Chinese (or Hong Kong) ebay stores for about $3USD (including shipping). This one is rated at 5.1v 0.4w (about the same as charging from a host PC), but for a little more money, you can get one with more charging (or operating) current:
