Solar Power Pennies
Description of build: Energy from pennies, as semi-conductors 🙂 Take 2 copper pennies, in the USA they must be from before 1982 as later ones have zinc under a copper plating. Place 1 penny on a gas or electric oven top. Heat at medium/high heat for 20 minutes. The penny will go black. Allow to cool thoroughly. Use water to remove the black oxide, to show red oxide underneath – this is your semi-conductor surface. For mine, I found that soldering to the pennies was difficult, so I cut grooves in them with a Dremmel and wrapped bare wire around. Make sure the 2 pennies are close but not touching and rmemeber it;s one burned one to one untouched one (though make sure the untouched is clean in itself, or it would be better at conducting an orchestra than electricity !) Next, use your fave salts mixture and build a salts cell, or put a heavy amount of salt in water and drain the water off. Then dip the pennies in the mixture. A wetted salt solution will dry, as shown in the video as the amperage decreases, but salt cells to the Bedini Earth Light method on Energetic Forum need not.
