Centralian invented Solar Night Light being used in typhoon-stricken areas

Solar Night Light by Silverio Navarro Jr.
Solar Night Light


Silver says:

It’s heart warming when I saw my invention being used to light up areas hit by Yolanda. Thanks to Shelter Foundation and TESDA for helping spread this technology.

It only started as a design challenge to light up at night the bottles on the roof that were promoted by Illac Diaz.

The design had to be simple using locally available parts and the device can be easily fabricated and repaired by local people.

After building the first prototypes, the interest to replicate this just spread like wildfire. Please sponsor the dissemination of the solar LED lamps to light up more lives. This is my contribution to humanity, galing sa Pinoy para sa mundo (from Filipinos for the world).

Engr. Silverio T. Navarro Jr. graduated Electrical Engineering at CPU in 1989. During his student days, he designed the electronic bell of Central Philippine University that plays the Alma Mater song to signal the start/end of every class period.

For readers who might search in the Internet and read the article about the Solar Night Light being attributed to University of Sto. Tomas engineering students, here’s what Silver said:

“I taught the UST students how to build the solar LED lamps with an instruction manual and guided them to talk to TESDA to promote this nationwide. There are several parties claiming who started this but they know it was yours truly who designed and built the first prototype. It’s self glorification to fight for this claim, so I focus more in helping others benefit from this technology. Others will use this for financial gains with selfish ends, so be warned.”

Infrastructure Management – Does CPU Teach This?

Infrastructure Management involves the prolonging of life and use of long-term assets for the common good.

Does CPU teach “Infrastructure Management”?

I’m a Civil Engineering graduate of CPU 1989 and I can’t recall encountering the phrase “infrastructure management”.

Maybe I wasn’t listening or I was absent when it was lectured but was the topic ever brought up in any of our subjects?

Our curriculum at that time included nine units of management but they are more related to financial and business management.

I could recall two phrases that could relate to infrastructure management topics, “sum-of-the-years digits” and “cost-benefit ratio” but they were never emphasized in that context.

Is “infrastructure management” in the vocabulary of Central Philippine University? The easy and fast way to know is to do a search in CPU’s website. I made a quick search and it can’t be found.

Anyway, Centralians need not be dismayed for the absence of “infrastructure management” (maybe during our years at CPU only) in our curriculum.

I’m sure that some civil engineer alumni have practiced infrastructure asset management in their profession, courtesy of learning through experience or formal training through their company.

I learned recently that infrastructure management is integral in New Zealand local government practices.

The basic aim of infrastructure asset management is to create plans and implement best practice procedures to maintain and prolong the service life of long-term infrastructure assets.

This is very crucial to supporting and sustaining the quality of life in the community. When infrastructures or assets are managed well, it has implication in local and national economy, especially when resources are very limited.

Going back to the question, I also have the big suspicion that other top engineering schools in the Philippines might be touching lightly on ‘infrastructure management’ and related topics.

If Central Philippine University gives emphasis on “Infrastructure Management”, she will soon be graduating people who are apt and ready to gain career in this area, maybe in their local districts initially and take on jobs internationally.

Philippine Association of Food Technologists, Inc. Annual Convention

Philippine Association of Food Technologists

The PAFT convention is for food technologists and other allied courses.

PAFT is one organization that addresses concerns related to food science and food technology. They advocate food safety.

The convention theme is about innovative food ingredients.

Packaging engineering, chemistry, chemical engineering and agricultural engineering, biochemistry, microbiologists and heads of higher education institutions are invited to attend.

Engr. Asiel Nils Castillon (CPU ChE 1987) currently sits as member of the PAFT board of directors.

He desires Centralians, students and professionals, to participate and be updated about current trends in food technology.
