WIND GENERATORS
blades you use, the greater the potential power produced, but the greater the drag. The tips of the blades
travel much faster than the base, so thin, narrow tips create less drag.
3–4.Answers will vary but should indicate an understanding that factors that increase lift and decrease drag
will increase both voltage and current.
5. Answers will vary, but most wind turbines are not very efficient at capturing the total power available
in the wind. If you were able to capture 100% of the energy available in the wind, you would stop the
wind. (Of course, you could not literally stop the wind, but instead the wind would flow around the
obstruction.)
6. Generally the windiest parts of Alaska are along the coast, especially in western Alaska and along
mountain ranges (Healy, Delta).
7. the north wind
8. Answers will vary slightly based on individual experience, but should include the idea that you should
hunt moose according to the wind. You should travel against the wind so that the moose does not smell
you.
9. Answers will vary slightly based on individual experience but should include the idea that traveling with
the wind can make your trip easier and faster (for you and your dog team).
