“A very simple modification to a standard electrical coverplate changes its function from one of consumption into conservation. A standard junction box behind the face plate catches your coins and saves them.”

Neat! I’d probably need a cash or credit card slot, but I like the concept. I wonder if there are any electrical metering attachments, somewhat like the iSave water meter concept. This almost makes me want to make a piggy bank for the green, sustainability, aids, foundations etc…take all that pocket change that pile high monthly and donate it. A Donation Piggy bank.
