“To reach the project’s goal of one minute of power generation for every ten minutes of laptop use, the generator would need to produce 20 watts (the laptop will require less than two watts in a primary application as an electronic textbook replacement).”

The generator can thus produce 20 watts if used continuously. The computer itself uses only 2 watts as compared to the 9 to 11 watts for the Q1.

So to answer your question: yes, you could charge your Q1 battery to 66% with one of these string chargers. However, it would require that you keep pulling the string for a full hour. Doesn’t sound like a lot of fun to me … yet it might be better than having to watch the in-flight entertainment ;-)
