Cool and cheap mini windturbine for kids

Cool build for a simple wind turbine that is pretty cheap to make, and can be used with kids.  Down sides, 1, the motor has to get pretty good speed to “light” the LED from my experience.  2,  I wish there was more on the propeller (like where did he buy it).  3, I don’t think I would buy an LED stake solar light just for the stake, maybe use an old broom handle or something.  Unless the author had plans to add a solar component at some point?
