Promhize: He copied it. It was an indian or philippine that invented it, I downloaded d video of an indian that did d samething a while back. Its on youtube, lemme look 4 d link

It's not even something u can use @ nite.

SimonAndal:
This is not logical. Light is most needed at night and this will not work at night.

caesaraba: This one is more expensive than buying bulbs na! Haba! From getting the water bottles, filling them up with water and adding bleach. Then to the unthinkable boring of holes in the roof and using adhesives to hold the bottles in place! Why not buy 50 naira bulb that can serve you both during the day and most importantly at night.

On the creative side, it's cool. But it's not really productive......well except of course I find myself in a prehistoric times or in a very remote region without electricity.

Jonwesley:

Haba, so if u buy N50 bulb to serve both day and night, do u get the light free or u do not remember ur meter or almighty PHCN. Do u think before u talk? Compare the overtime usage of electricity with this concept that only has a fixed cost at the beginning: the cost of bleach, and adhesives.

zig2ryme04: ok...so? should i shout hallelujah or jump up?

yunfazz: What a brilliant idea!

A Brazilian mechanic has invented a way of lighting bulbs without electricity- using plastic bottles filled up with water and a splash of bleach.

The secret: Adding two capfuls of bleach to a bottle of water stops it from turning green when exposed to sunlight. He then drills a hole in a roof tile and pushes the filled bottle in from below. He keeps the bottle in place with polyester resin, which waterproofs the 'window' in his roof. More photos after the cut:

During a power shortage, it was his boss that first suggested the use of a plastic bottle filled with water as a lens to focus the sun's rays on dry grass and to light fires in case of an emergency. It was after then that Mr. Moser developed the concept into his Moser Light.

In a statement to the BBC World Service, he was quoted as saying: 'It's a divine light. God gave the sun to everyone, and light is for everyone. Whoever wants it saves money. You can't get an electric shock from it, and it doesn't cost a penny."

Wow..!!! The man should patent his invention immediately and not forget to fly to Nigeria asap too...we have plenty of water bottles and sunlight!!!

Promhize: Op u are a very funny somebody o
Patent what, what do u patent about this.
So because I want to put a bottle filled with water In my roof, I will call him and his team or seek his approval, are u high??

mozeybee: [quote author=mozeybee. As much as much credit should be given to such seaming creativity, I have reservations on its need.
1. U have to drill through the roof. what should a man in the ground floor of a multi-storey building drill?
The solar light bulb (SLB) is not for everybody. Meaning that if you live in the ground floor of a multi-storey building, even in the darkest slum, it is less likely that you will use it, even if you live in the top-most floor. The cost of installation in the latter case will likely increase.
2. Even if the bleach keeps the water colourless, what will keep the "plastic " bottles from melting after persistent solar radiation absorption? Common sense will tell that plastic will contract/shrink/melt when exposed to solar radiation beyond its thermal limit.
There are other option apart from plastic bottles. But important to note that common plastic bottles are made with PET (Polyethylene terephthalate) which I understand has a melting point of 250 oC, more than twice the boiling point of water. So, common plastic bottle is ideal, except if you live close to the sun or in the middle of an hydrothermal vent.
3. Even if you aren't living under storey buildings, why perforate ur roof (giving room to leakage during rainfall) when a transparent roof would simply do? I've seen many warehouses with such desings to allow sunlight in from the roof.
A living space is different from a warehouse. The general preference for roofing are non-transparent materials. Transparent material may increase temperature in the room.
4. Again, since it only works in the day, why drill the roof when the windows would let in sunlight anyway?
Not all houses have the luxury of a window. You need to take a trip to a typical slum.
5. Finally, electricity gives us much more than lightning the room. Can the mosar bulb power the electrical appliances in the house?
The application is for lightening not electric generation.
I really commend the trial but it isn't SCIENCE since there is no TRANSFER OF ENERGY. Thinks about it - It's just LIGHT ENERGY to LIGHT ENERGY. If this is not science, so what is science? More so the concept is already being used in some countries. So what proof of concept (i.e. trial) are you talking about?
