design gadget :: Sun jar

Jam jars store jam,
the Sun jar collects and stores sunshine so that you can use it at night

Made with a traditional Mason jar and high tech energy efficient lighting! Captured inside the jar are a highly efficient solar cell, rechargeable battery and low energy LED lamps. When the jar is placed in sunlight the solar cell creates an electrical current that charges the battery over a few hours. This energy is then used at night to power the three LED lamps inside the jar.
