An outdoor light that doesn't require batteries

Have you ever thought about being able to generate electricity from salt water?Have you ever thought about being able to use salt water for lighting?If you have such an idea, then you may be interested in this startup project called Waterlight. This is one that can generate electricity through a chemical reaction with salt water to drive LED light bulbs and even charge smartphones. It can work continuously for up to 5600 hours, which is a long-life product.How does it work?What commercial value does it have?


The principle of Waterlight is simple. It takes advantage of a basic chemical phenomenon. Electrolysi. Electrolysis refers to the process of REDOX reaction of ions in electrolyte solution or molten electrolyte under the action of electric field, thus generating current.Electrolytes are substances that can be broken down into positive and negative ions in water, such as salts, acids, bases, etc.Electrolysis requires two electrodes connected to the positive and negative electrodes of an external circuit, and a conductive liquid, usually an electrolyte solution.

Waterlight takes advantage of this principle by using salt water as a conductive liquid and two different metals as electrodes to generate an electric current through a chemical reaction.

Waterlight has many advantages over other lighting equipment, mainly the following points:

  1. Environmental protection: Waterlight uses saltwater, a renewable energy source, and does not require the use of any fossil fuels or polluting substances.It also does not produce any harmful waste or gases and is friendly to the environment.
  2. Economy: Waterlight uses cheap and readily available materials - salt and water - that don't cost much.It also does not require frequent replacement of parts or maintenance, only regular replacement of salt water and electrodes.
  3. Convenient and convenient: Waterlight is very easy to use, just need to add salt water and press a switch to glow.It can also be carried and used anytime, anywhere, regardless of geography or weather.
  4. Multifunction: Waterlight can not only provide lighting functions, but also charge devices such as smartphones.It can also adjust brightness and color to suit different occasions and needs.Do you think this kind of light will become the mainstream in the future? Would you like to give it a try?
