For a more long-term approach to the problem though, there's always the option of using rechargeable batteries.
So your alkaline batteries can't power any of your gadgets anymore. In fact, they're so drained they can't even be used for the remote control. With the Energy Seed concept designed by South Korean Sung Woo Park, these old batteries are given a whole new purpose. Instead of being sent for recycling (or more realistically, being thrown away), they could be used to power LED street lamps. |
