The Human Battery ( & H2O ) This battery can supply enough electric current. to power such devices as a digital clock / wristwatch, a digital calculator with just your fingers tips,.. It can also generate a continuous current by holding the battery under a dripping water tap or from a roof down spout during a rain shower ( the chemical component )....Wrapping a honey mandarin orange peel tightly around the human battery will also power the digital clock for up to 5-hours or more...So recycling does pay...My next challenge is to design a battery that uses humidity / water vapor... Will it happen, I think so, wait and see...Designed By: Lorrie Matchett ( [email protected] )
