The Coin Lamp operates on a very basic principle - no money, no honey. It will only light up whenever you insert coins inside, and the lamp itself has been specially set to a pre-determined time by an internal mechanism. It was specially developed with the assistance of a NESTA training programme, where the final product will be available sometime in the near future. I guess this is a good way for folks who want to save as much money as possible, as the coins stored in the Coin Lamp could be used to offset the monthly power bill.
