Christopher writes - "Handcrank rechargable flashlights are a great idea (not my idea - just a great idea). LED's comsume very little power compared to traditional blubs and last a lot longer. Throw in the need to never change the batteries and it makes a simple yet elegant solution to the age old problem of the absence of light." - Link.
