Obama hails Pinay scientist's saltwater lamp


MANILA – US President Barack Obama hailed a Filipina scientist's invention, a lamp that runs on saltwater, as the US leader made a push for the use of renewable energy ahead of a crucial meeting in Paris that will weigh heavily on the future of the earth.

During a light moment at the Asia-Pacific Economic Cooperation (APEC) CEO Summit, Obama admired De La Salle University faculty member Aisa Mijeno for making the aspirations of ordinary people as her inspiration in coming up with an invention that provides a very basic necessity that is also environmentally sustainable.

''One of the most important things you said, in my mind at least, is that this starts from the bottom,'' Obama told Mjieno.

''If we're working at the grassroots level, seeing what folks need and figuring out efficient way how to deliver an improved quality of life while being environmentally sustainable, that's an enormous opportunity. But it starts at looking at the aspiration and hopes of ordinary people."

Mijeno's multi-awarded SALt (Sustainable Alternative Lighting) lamp runs on saltwater and can last for up to 8 hours before the saline solution inside it requires replacement.

''The main science behind the lamp is it’s a chemical reaction. You try to convert chemical reaction into energy. There's something inside the lamp and you have to change it, but you only have to change every 6 months if you are using the lamp 8 hours a day,'' Mijeno explained to Obama.

Mijeno said the idea of the SALt lamp was conceived when she visited mountain communities in Kalinga, where people had to walk for hours a day just to get kerosene to power their lamps.

Obama, in turn, said Mijeno is a ''perfect example of what we're seeing in a lot of countries – young entrepreneurs coming up with leapfrog technologies."

''They did not have to make some of the massive infra investments. This is part of the reason why the old idea of development and environmental sustainability is outdated. It does raise the issue though of what we can do support young entrepreneurs like Aisa,'' he said.

Obama said governments should provide tax incentives for those producing renewable and alternative sources of energy and help and provide support for research and development.

Mijeno said the SALt lamp project is now on its critical phase as she and her team attempt to mass produce the lamp.

''What we need is support from the private sector and the government to mentor us how we can scale up the project, [give] support in terms of funding,'' she said.

CLIMATE CHANGE SUMMIT

In his speech during the summit, Obama said renewable technology is the way to go with traditional sources of energy threatening the earth's climate.

Obama will attend a climate change conference in Paris, France by the end of the month where world leaders will craft a legally binding agreement on lowering carbon emissions.

Obama said the climate change conference would provide ''opportunities'' for businesses because the agreement will usher in ''new jobs and opportunities and an investment in technology that frankly needs a boost right now.''

''The urgent and growing threat of climate change is a challenge but also, I would argue, an opportunity,'' he said.

''An ambitious agreement in Paris will prompt investors to invest in clean energy technologies because they will understand the world is committed to a low-carbon future.''

The Philippines has already submitted its climate change mitigation and adaptation plan to the UN Framework Convention on Climate Change.

Obama said more than 160 countries, representing 90 percent of global emissions, have put forward climate targets for post-2020.

The Philippines had earlier said it would cut the archipelago nation's carbon emissions by 70 percent by 2030 but only if it receives support from developed nations.

Pinay scientist creates lamp that runs on saltwater


MANILA – “To light up the rest of the Philippines sustainably” was the vision of Filipina scientist Aisa Mijeno when she made the Sustainable Alternative Lighting (SALt) lamp.

The SALt Lamp is an environment-friendly and sustainable alternative light source that runs on saltwater, making it suitable to those who live in coastal areas.

It can also function well in remote barrios. With just two table spoons of salt and one glass of tap water, this ecologically designed lamp can run for eight hours.

“It is made of tediously experimented and improved chemical compounds, catalysts, and metal alloys that when submerged in electrolytes will generate electricity,” Mijeno explained in an interview with ABS-CBN.

Because of its inspiring vision and ground-breaking innovation, the SALt lamp has received various awards and recognition from organizations in the Philippines, Singapore, Japan, and South Korea.

It has also won in several competitions here and abroad.



Safe alternative to traditional lamps

According to Mijeno, the idea behind the SALt lamp is the chemical conversion of energy. It utilizes the scientific process behind the Galvanic cell, but instead of electrolytes, the SALt lamp uses saline solution, making it harmless and non-toxic.

Compared with kerosene lamp, the SALt lamp is also a lot safer, Mijeno stressed since it does not have components and compounds that may spark fire. Moreover, it does not emit toxic gases and leaves minimal carbon footprint.

“This isn’t just a product. It’s a social movement,” she said.

Although the SALt lamp is not yet being mass-produced, Mijeno and her team have been working intensively with non-government organizations (NGOs), local government units (LGUs), and charitable foundations, among others.

These organizations aid in the purchase and distribution of the SALt lamps to remote communities where electricity is scarce, or worse, not available.

A sustainable light for the Philippines



Mijeno said that her experience working with an environmental organization made her realize the need for an alternative source of light, especially in rural areas of the Philippines.

“I used to be part of Greenpeace Philippines and did personal immersions/volunteers across rural communities, and there I learned so many things. Most of these people are so poor and underprivileged that they endure long hours of walking just to get kerosene for their lamps,” Mijeno recalled.

Currently, for every SALt lamp that is bought, one lamp is given to a selected family.

“Our main focus is on the island communities that do not have access to electricity and have no financial capacity for acquiring alternative source of electricity,” Mijeno added.
