The PowerFilm Solar Battery Charger. Hmm…a flexible roll up solar charger. I can see that. Priced from around $100.00.

‘PowerFilm solar panels are monolithically integrated which eliminates the need for damage-prone manual connections of individual solar cells. PowerFilm is made of silicon, a natural resource in abundant supply. Also PowerFilm performs well in diverse enviroments [sic], including hot sun, and does not suffer from wasted over-voltage. Cadmium Free.’
