Liquid light system

Did you know that sea water or even very dirty water at the village can be a source of light at your home? According to Alan Riser the brain behind the invention, there is stored energy in water inform of oxygen minerals and microorganisms.


During his presentation at the TUM’s marine Engineering block on 15th February 2016, Students, Lecturers and Professors were astounded by his technology. The light produced an amazing amount of power because of the close proximity to the ocean. The water he used was a bit salty and full of minerals which produced an amazing amount of output in the liquid light system. 

Riser highlighted that carbon, magnesium plates, wires, torch and water are some of key materials needed for the system to work.

“The LED light is powered by water. These lights are designed for rural villages without access to electricity or they can be used for emergency lighting. No batteries required, just add water. Simple and green, this system contains NO Toxic chemicals and is environmentally friendly.” Riser explained.

He described liquid light model as one of the simplest models in light production.

“Just drop the plates into any river, lake or plastic bucket. If you have the portable model just open the lid and add about one and half litres of water .If you use dirty water you can expect better performance and better light output. One and half litres of dirty water should run your light for several months or longer.” Riser explained.

He revealed that one can even mix in a little clay soil, swampy mud, sugar, or animal waste manure into the water. This will add energy to the light system in form of microbes which produce oxygen and increase performance of the system. If the light gets dim one is supposed to pour out the water and add new and will light at full brightness again. Water can be added as many times as possible and the light will continue as long as the plates are intact.


“If you are using a stream or a river the light will stay on as long as the plates are in the water. To turn the light off just remove the plates from the water, dump the water from your container or disconnect one wire by removing the wire nut and separating the two bare ends so that they are not touching.” Riser noted. 

After answering a lot of questions from students and lecturers he closed his presentation by telling the audience that they will find true happiness when they're in the service of others.

Riser who is based in the United States of America runs an organization by the name Charitable Ingenuity. His inventions are mainly meant to help people in remote villages who have no access to electricity. He has initiated projects in Zambia, Ethiopia, Uganda, Tanzania, Zimbabwe and Kenya.

    am Kahindi katana very soon I will join tum through God's effort to do bachelor of technology in marine engineering. I like that presentation because it opens up our minds to think smart in the field of engineering and technology.
