Looks like a great idea for the beach!

This kind of low-power application is GREAT for solar panels. I'm sick of people trying to put them on everything (like electric cars... do you know how impractical it would be to put them on a Tesla based on their current efficiency and cost?)

Awesome. This makes a lot of sense. An e-book reader should always have lots of surface area (since you don't want to read on a tiny screen) and requires very little power. I'm almost surprised e-book readers weren't built this way in the first place.
