Philippine architect and scientist Aisa Mijeno has created a revolutionary lamp that does not require batteries to emit light in just one glass of salt water. She hopes to bring to light people in other parts of the Philippines in a sustainable way by finding an environmentally friendly and locally adapted source for people living in the coastal areas. She had lived in the Butbut tribe in Karinj province, Philippines, for some time without electricity, and she had the idea of ​​making a brine light.
With just a glass of water and two tablespoons of salt water, the salt water lamp will give people eight hours of light. Mijeno explains: "I did a lot of tedious experiments before doing this lamp to continually refine compounds, catalysts and metal alloys that generate electricity when they are immersed in the electrolyte." The rationale behind this is to shift the chemical energy For electricity, although it takes advantage of the science of galvanic cells, it makes use of non-toxic brine rather than harmful electrolytes.
Saltwater lights not only bring light to remote areas, but are also cheaper and safer than traditional kerosene and electric lights. It does not contain any ingredients or compounds that may cause a fire, nor does it produce toxic gases, nor does it have a carbon footprint. Mijeno said: "It's not just a product, it's a social movement."
Although it has not been produced yet, it has gained global recognition. Mijeno produced the equipment that she won in the Philippines, Japan, Singapore and South Korea won a lot of rewards and competitions. The New York Times recently reported that she attended a climate change seminar presided over by President Obama, where she presented all the details of the brine lights. President Obama praised her for daring to put her best ideas into action and described her as "the best example of creating a young entrepreneur across technology."
At the moment, Mijeno's challenge lies in finding a durable, economical and easy-to-maintain way to mass-produce brine lights. If she succeeds, then people will be able to get 90 lumens of light for just $ 20 and replace the anode for only $ 3 every six months. This is perfect for areas without electricity and is also safer than kerosene lamps. There is also a USB excuse above the brine lights that people can use to charge their cell phones or other electronic devices. If everything goes according to plan, Mijeno estimates the product will be available by 2016.
"The disadvantage of kerosene lamps is that it can cause a fire," she said. "We wanted to use salt water or sea water to provide people with a cheaper, safer and more environmentally friendly lamp."
