Sebastian Africano was just through the SF Bay area, building stoves on his way to Stove Camp, and I added this post on his workshop to my evolving IAP site:

Experiences Using a Hand Crank Generator for Fan Stoves

For about four months I have had a hand crank powered LED flashlight that I have been very impressed with (http://www.freeplayenergy.com/products/illumination/jonta, and other retailers such as REI sell it for less - ~$50) – it can either be charged by its AC adapter or by turning a hand crank, the high performance LED is extremely bright, the flashlight has several intensity settings, it lasts longer on a full charge than I can easily measure, and my model is heavily rubberized for ruggedness and waterproof characteristics. It is by far the best of the many LED flashlights that I have tried, including both moving magnet and straight battery powered ones – this one seems very bombproof and efficient; several of us have been very pleased with it.
