An Invention That (Could) Change the World

[Retz]

my only complain with LED's is that it is good for low ceiling lighting. pag high ceiling na hindi na umaabot sa slab ung kinang ng LED.

Depends on how they're aimed/focused.... and how many watts the bulb is. LED floodlights can be very effective.

State of the Art Pinoy engineering.

Next, the PhUV naman.

With the PhUV, they were trying to reinvent the wheel. Use ultra-cheap Chinese mechanicals, mated to bespoke sheetmetal, fiberglass and lights that were not cost-effective to design, buy and produce. In the end, you have a UV that cost almost as much as a Chinese UV but was uglier. A lot of us posited ways in which the design could be improved to cut costs and make it look attractive.

The inventor of the bottle light has never claimed it to be "state-of-the-art" or "super-duper-califragilistic-eco-duper-osius"... just that it was easy to make, easy to teach people to make and cheap for them to make and sell. There is no illusion that this will replace electric lights completely. Just that it will help reduce the need for them.

You really should watch interviews with him. Some of the stuff his group does (like buildings which use sacks, plastic bottles and adobe) looks simple, but is effective, robust and reproducible.

This is opposed to most "green" initiatives, which are complex, expensive and unreliable.

You're probably not using the correct LED lumens and/or lighting fixture for your environment.

currently im using T5 fluorescent lamp and sinubukan kong palitan ng T5 Led with a lower wattage that is equivalent to a T5 Fluorescent 54W, yan ung na observe ko.

I replaced a 25w circular with a 7w LED. The 7w is brighter.

There are many different kinds of LED. The early ones with exposed bulbs surrounded by reflectors were inadequate. Newer ones have diffusers much like some CFLs. They're pretty good.

FINALLY, the most sensible man in this forum butted in and gave credit to the man and the idea behind the invention ;)

Thanks for sharing your progressive thoughts on this.... Just like in the old days, people who were still riding horses and carts, including the elitists opined that the car will never be able to replace the their trusty carriages because they say that they just couldn't stand the smoke coming out of the engine.... And they were proven wrong ;)

The typical Pinoy mentality is just like any "instigator" or "pot-stirrer", has never matured nor become a progressive thinker thru the centuries; no wonder why the country runs in mayhem that there was even no single industry developed known to fuel industrialisation thus were labelled only as a trading country.... That's why when we're hit by regional crisis, we feel the impact heavily.... Imagine US$0.28 per kW-h cost on power alone and a population ballooning to 102.5 M Pinoys in 2013, to name a few of the many woes in the country.

And ingenious ways like this just won't survive in Pinas because of the "talangka mentality" nothwithstanding that it is somehwat still in its maiden voyage and can still be improved in who knows how long, say, 5 years down the line when another individual or group decides to do something about it at a cost-effective manner.

Dinaig natin sa power cost, fuel cost pati sa population (to name a few) mga SE Asian neighbours natin (except Indonesia), pero tinalo nila tayo sa economic level nila hehe - Indeed, ONLY IN THE PHELIPENS

What a bang of description boss Niky! 5-star rating ang comment mo!

Cheers!

sa ibang news naman ... ginagamit yung plastic bottles as "float device" ... sama-sama nakatali gawing salbabida, rescue boat para baha ... basta hwag lang leaky yung takip, reliable siguro yun

Solar-powered lamp.



Little Sun Philippines

What is the Little Sun?

A high-quality solar-powered lamp in the shape of a hand-sized sun.

A social business that produces Little Sun lamps and distributes them worldwide by establishing sustainable trade routes, allowing off-grid distributors to profit while bringing light to local users.

A global project connecting the world’s electrified areas with off-grid communities – purchasing a Little Sun at the regular price of €20 in areas of the world with electricity allows Little Suns to be sold off-grid at much lower, locally affordable prices.


A work of art that works in life.
