This spinning motor makes for a great Christmas tree decoration, best of all it doesn’t need to be plugged in. The creator is hoping for a 100 year run time! Not sure if it will last that long since most batteries have an internal discharge rate that will kill it in a handful of years without powering anything but this motor is running from home made Crystal Cells. The motor draws around 3 uA which is a very low draw but as things wear out drag may increase this significantly.
What do you think? Is this just wishful thinking or does this combination stand a change of making it?
