Green House - LED lantern lights up with electricity generated by water and salt

Green House is going to release an LED lantern in mid-June that generates electricity by water and salt.

It doesn't need any batteries or electric charge. Just by pouring salt water into the lantern, ion seeps out of the built-in magnesium metallic bar and generates electric power.

Ocean water can be used so that it could be the perfect tool for emergencies and outdoor activity.

With the generated power, you can charge up USB devices using a USB cable. However, the output current is about 40mA so devices that need higher current such as smartphones are not supported.

  • Price: 3,700 yen
  • Size: 188x110x85mm
  • Weight: 357g
