An Invention That (Could) Change the World

[d_mac]

NECESSITY IS THE MOTHER OF ALL INVENTIONS.... So the saying goes....

BBC News - Alfredo Moser: Bottle light inventor proud to be poor

P.S.
Former Pinoy actor and model turned social entrepreneur, Iliac Diaz, is behind the business (A Liter of Light) that supply and install such lights in Philippines - talk about a fruitful partnership with English billionaire, David de Rothschild hehe....

Liter Of Light

Liter of Light » David de Rothschild together with Illac Diaz, founder of My Shelter Foundation, promoted the use of plastic bottles cum solar light bulbs

na feature yan invention ni illac before. sana it could store enerygy as well para kahit gabi may ilaw pa din.

parang minodify na nya yung design, meron nang maliit na solar panel para sa gabi napanood ko nitong taon lang.

Instead of electrifying the provinces, butas sa bubong na lang.::rofl::

Not really idol, you have to remember the (Philippine) business associated with it is social entrepreneurial, where much of it, if not all, is free and voluntary.... Moreover, the men behind its distribution in Pinas are know international (and local) philanthropists (Rothschild and Diaz).... Also, the Brazilian inventor behind it does not exclusively claim and hold rights on it, that's why he doesn't receive any sizeable royalties from it and patents, if any.

If you have a power cost of about US$0.28 per kW-h (and going up without letting up - figure care of Meralco's PhP12.00 per kW-h), and at the same time, a meager to middle-of-the-road income earner, incidentally where most Pinoys belong to in terms of salaries and wages, you would entertain the idea of installing lots of these water bottles into your home to save electricity at least in the day-time. Vietnam, Malaysia and some of the other SE Asian countries more progressive than Philippines charge a power cost of only US$0.068 to US$0.070 per KW-h. Even a 1st world country like New Zealand charges only in recent past years NZ$0.03 per KW-h.

In our house, on the other hand, we use multiple skylights where the windows for them in the roof are tilted to the north or south, which ever looks better aesthetically ---- and the sun travels from east-to-west, hence you get the point, no direct light and heat from the sun going inside the house.... So no need for us to adopt the water bottle idea, at the current only, but who knows into the future.

Cheers!

IMO, people need lighting at night. While this is helpful, it doesn't function at night, the time when children would study or parents prepare for the next day.

So I agree it kinda look backwards in a sense. And I wonder if they really ask what the people need. Lighting in the morning or at night???

Sana water will also work like an optic fiber. Para yung light will pass through the tubig from the plastic bottle could be extended to another location.

pang cave man naman kasi yan ganyan invention.....

mag lalagay ka ba nyan sa bahay mo?

bubutasin mo ba bubong mo dyan?

mas malaki pa ang cost mo dyan kesa bumile ka ng LED BULDS...

[wezz_zzew]

Good news to para sa mga bosero.
Pwede naman window na glass tapos meron lang grills. Yung sa amin pag itinaas yung blinds sobrang liwanag.

[Ry_Tower]

Just improve the battery para solar power will be more efficient and cost-effective.

Yung tipong for the same size, almost twice the energy can be stored and the battery could last twice as long din. So in effect parang 50% disocunt sa current rates.

Plus improve ba LED's na lights and inverter appliances.

Its a stop-gap measure. It wasn't really intended to replace the light bulb, but just an alternative means of lighting places without the need to use electricity.

Some people will appreciate the technology behind the invention, and some will only see the negative. Madaling bumili ng bulb or mag-install ng skylight kung meron kang pambili. Its a better alternative than seeing people stealing electricity from the grid through illegal connections.

how can that "invention" change the world?

it's a freaking light bulb for daytime use

buti sana kung pang gabi na di kailangan ng kuryente

[oj88]

It is pretty ingenious but I wouldn't exactly call it world-changing.

it's not gonna change the world really. just improve the lives of people at the bottom of the barrel. the title is just using sensationalism to attract attention.

That's the whole point of using water. It scatters the light.

If you just put a hole in the roof, the light will go straight down. Diffract it through water and it fills the whole room.

LED bulbs still cost a lot. An LED bulb that is as bright as a solar light is around 250 (super cheap) to 600 pesos (regular price).

-

Many public buildings, offices and modern homes are built to take advantage of natural lighting. Our new City Hall has a lot of natural light, so even if all the hallways are equipped with LED bulbs, they're almost never on, not like the old, enclosed City Hall.

-

The typical baro baro in the slum is built wall-to-wall with the next baro baro... and there's very little natural lighting to be had from open windows. A solar bulb like this is much less expensive than a natural skylight or even installing a light bulb (needs bulb, mount, switch, electrical wiring, etcetera). It can be done for just a hundred bucks (retail... cost to do is just 50 pesos). It's not useful the entire day, but it can cut down on the need for electricity. If it saves a household 100-200 pesos a month... with the only maintenance cost being to replace the water every few months... isn't it worth it?

It may look funny to us, but it's cost-effective engineering. Which is why people are praising it.

State of the Art Pinoy engineering.

Next, the PhUV naman.
