The Sun Jar

The Sun Jar, made only from a traditional Mason jar and some energy-efficient lighting, collects energy from the sun to be used for 5 hours of light at night. The light is captured in the jar by a solar cell, rechargeable battery and low energy LED lamps.

To work, the Jar needs to be placed in sunlight (either in a lighted window or outside in any type of weather condition, thanks to its weather tight seal) and the solar cell creates an electrical current that then gradually charges the battery. When fully charged, the energy powers three LED lamps inside the Sun Jar. The Sun Jar is “smart” as it’s installed with a light sensor that detects when it gets dark to activate the light.

  1. That is a pretty cool jar. I think my daughter would love that for a nightlight.

  2. I think this is great. I would love to make this. Do you happen to know what materials they used?

    Thans for the great idea!

  3. I’m not sure about the materials used (maybe if they told us we could build it on our own!).

  4. Great idea! Thanks for the post.
