I’d like to present you Solar LED bricks. This technology is using the solar power to charge a capacitor, which is stored inside of the light, and then during the night, the energy is restored. The company which is manufacturing this equipement is called Simbiousa and you can find their website here.
The bricks (or lights) are fitted with an ultra-capacitor . There is 5 LED colors for you to choose from: yellow, blue, red, green and of course white. It’s pretty cool. What do you think?
