Anyone who graduated high school should know that potatoes can be used to generate electricity. One person, however, took that idea to the next level by stringing together 500 pounds of potatoes together, generating five volts in the process. The potato battery then powered a small audio system, which neighbors got a chance to listen to while wondering, "Am I crazy, or am I listening to Neil Diamond being powered by a bunch of spuds?" Who says battery technology is hampering mobile technology?
