Uncharted Play is a company that, believe it or not, manufactures a soccer ball called “Soccket II,” which can be used to power a lamp for three hours after it is played with for 30 minutes. This unique source of renewable energy opens the door to new ways of thinking about alternative power.
There appear to be no limits to what can be used as sources of renewable energy. The imagination and creativity of scientists and researchers have no boundaries and the next new alternative fuel they develop may be even more surprising.
