Beacon: Salt Water Powered Lighting
Have been cheated so many times, the first reaction comes to my mind when I heard water powered is another scam. If you are someone just like me, probably read the title one more time. It is “salt water powered”. And this technology does exist already and has been widely used in many products. Academically, it is called “Osmotic power” which is one of the blue energy available from the difference in the salt concentration between seawater and river water. Beacon, the salt water powered lighting is designed base this technology by Carmen Cumming. If this design can be put into production, it will be a good new to people who live close to the sea and can’t afford normal lighting. As long as you have the product, what you need to do is just to refill salt with and the galvanic cell battery system will work on its own to generate power to provides illumination. Moreover, this design is quite safe which means even kids can operate it.
