HELLO EVERYONE,

Lemme do the math. Hamster can apply a maximum force roughly equal to its weight (30 grams * g = 0.3 N), at a velocity equal to its run speed -- let's say 1 meter/second or so -- for a total power output of about 0.3 watts. Cell phone batteries hold something like 2500 mAh at 3.8 volts for a total energy of 30 kJ.

So in an ideal situation, it'd take about 24 hours to charge a typical phone on hamster power. Keep it up little guy!
