Solar Bottle Bulb - San Pedro, Laguna Site

[raktsik24]

kelan po naganap tong csr ng pepsi??

[sabelilah]

but u already have light in the morning, what about at night?

[aeternusero]

@sabelilah

You use your electric bulbs.....

[prasob1]

Thank you for this video, I proposed this for my cousin in school for science exhibition & he won the first prize... We are from India... Thank you so much to the all the persons who worked on it & special thanks to youtube !

[SamuelJoaodaSuica]

fuck MIT

Brazilian Auto Mechanics FTW!!! Thank you for your wonderful contribution!!!

[pagkabolingitjud]

while i appreciate it, sa tingin ko hindi yan kailangan in the first place. nasa pagdesign yan ng rum o bahay to make use of the light outside. hindi kailangan ang butas-butas na yan...

[mnmc10]

@pagkabolingitjud nakapunta ka na ba sa squatters area? kung saan dikit dikit ang bahay? kahit may bintana ka walang sikat ng araw na pumapasok.

[aixledizon]

so my question is, how do you turn it off?

[oolcat1]

@aixledizon the sun goes down id presume

[SamuelJoaodaSuica]

@aixledizon

you can put a black cup over the bottle during the day time... And in the night time it's already off anyway. They probably use candles or something with fire to have light at night...

ang importante nagagamit ng mga kababayan natin wala ako paki kung sino man nag imbento nito atleast alam ko mabait sya at tulong sa mahihirap

@rbarbieri1 : You are right about the mechanic who first used the solar bottle bulb in Brazil. His name is Alfredo Moser from Brazil and he has a video he posted three years ago on YouTube. We will give him proper credit as has A Liter of Light on their website. What a brilliant idea. If I can find his email I will write to him as well. Any more info is much appreciated. We are going to start using this idea here in Guatemala soon. CatherineTodd2 at gmail dot com

Wasn't a Filipino who invented this. This had been done in many South American countries way before it was introduced in the Philipines. Won't work at night, simplified skylight lang ito para sa daytime.

Genius

[digitalkrashed]

what if plastic depolymerized over time, it'll get brittle and someday you'll get water in the house.

[3rdMayhem]

@digitalkrashed That probably takes longer than the lifetime of these shacks

[tatapudi]

@digitalkrashed

well, its 2/3litres of water, eventually it will dry off... also poor dont hav to worry about carpets...

[sailingsolar]

Making holes in any roof is a potential leak over time. I suppose using transparent corrugated fiberglass panels cut in 2 ft lengths instead will be the next big breakthrough. That would let way more light in. SS

[bigxsig]

@sailingsolar well the whole point is to utilize what they already have; corrugated metal roofs, plastic bottles, water, and chlorine, and something to seal the joint. transparent corrugated fiberglass panels would require spending money that they don't have. The whole point in using the bottles is so they don't require a big whole to let light in, or an overly transparent, expensive, roof/ceiling

[tatapudi]

@sailingsolar I agree that there is a potential risk of leaks. but I see he was sealing with cement. And most people might not afford a fibreglass sheet. this looks simple. works for them...

[CommentsSurvey]

@sailingsolar : I have asked people in Guatemala why they don't use transparent fiberglass panels in two foot lengths for light, and they say that it gets too hot in the room and makes it easier for robbers and thieves to enter. Makes sense. That's why we're going to test these solar bottle bulbs, and test them with different caulks for leaks before we start cutting holes in roofs. But the special volcanized caulk they are using in the Phillipines is working; I'm sure we can make it work here.

Plagiarism!

This idea was created by an auto mechanic in Uberaba, Minas Gerais, Brazil in 2002, and NOT by students of Massachusetts Institute of Technology (MIT).

[bulos45]

hindi po pinoy ang nagimbento nito kundi mga estudyante ng MIT sa USA :)

[urban05]

mainit nman walang kisame.

[katchatoredvd]

galing naman nyan. yan ang pinoy

[katchatoredvd]

galing naman nyan



[violetisredandblue]

what does the bottle contain? water?

[ryuuzaki002]

@violetisredandblue Water. And a little amount of chlorine.

[oblak99]

Pag Gabi Pundido ba toh? :D Good Job!!

[nil1230]

do u think it works better w/ glass ? coz its much clearer than plastic botter=brighter..imagine a sky window+chlorine..wow..

[nil1230]

they need to develope a better one, one that can last through the night. experiment w/some chemicals..

[roogz]

@DanFrederiksen - you're stupid... do your research first, skylight/putting a hole will cast a direct light to the floor, the solar bottle bulb will scatter the light 360 degrees around the place just like the bulb.

[CommentsSurvey]

This is TERRIFIC. Can't wait to try it at Lake Atitlan, Guatemala, where I live part time. Where can we find written INSTRUCTIONS?

[DanFrederiksen]

that's just a window.. or a skylight.

[jomer32595]

ito ang dapat ipinagmamalaki ng pilipinas. simpleng bote naging ilaw. nagrecycle ka na, may ilaw na rin at nakatipid ka pa... di ba san ka pa?

[immiecustodio]

hi hi hi himga kpitbahay ko kya yan lalu n ung my tindhan mabait smin yan

[tangadsangig]

oo nga daytime lang ano? pero ok di naman

[cvmontejo]

Gaano katagal yung ilaw? Pwede lng ba sa umaga? Sana pwede sa gabi rin sa loob ng mga bahay. Iba na nakakatipid. Salamat!

[MrKHREINZ1]

morning lang ba ginagmit yan

[SOMEONEatYOURback]

good!

[shriilaksmi]

haha....go ate amie(ung nkablue tas nka short)..haha
