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.

Think and read carefully before typing. It is to serve you when when there is power outage during the day. unless of course ur 50 naira bulb can power itself.

adeoflagos: According to the World Bank, the inventor is Alfredo Moser (use Google). For now, its application is limited to day-time in human settlements (e.g. slums) where rooms are in darkness day or night. I read someone (SayITnw) write something about seeking cheap publicity on nairaland for such a great and in-use concept. How much publicity does an idea that is already on the website of a global financial institution need. "Nada"!!! Not from nairaland.

How could this be more expensive than buying electric light bulbs (ELB)? You pay for the ELB as well as the electricity. How much energy goes into production of the ELB and the electricity, which are likely produced from non-renewable sources.
You seem to have forgotten that we don't pay for electricity just to light bulbs. How much kWatt does a bulb condume in a room housing an electic iron, electric stove, refrigerator, AC, TV sets, etc. ? less than 8%! If u caim that the bulb is expensive, is the bottle free? You have to buy it afterall. The dividing lines between this Mosar bulb and the "Legendary" Faraday's bulb are - reliability & efficiency. You can use the bulb at anytime & at steady brightness. The mosar bulb is dependent on an astronomical body - the sun, and is therefore time-dependent. It deems off towards the night.
More so, some energy that is converted from electric energy to light energy by some bulbs is lost as heat. The initial cost of the solar light bulb (SLB) will likely be recouped over the life time of its use. The other benefits (i) wastes bottles are recycled and reused
The usefulness of any idea (sometimes cheaply called innovation) is in weighing its merits against its demerits. Is the recycling process the drilling of rooftops? This will only pave way to imminent leakage from the roof. Again, how do use it even use it in nigeria when most buildings have ceilings below the roof? Do u drill the ceilings too or u produce some 5-feet bottles ?
(ii) in the long-term the amount of waste-bottles that end up in landfills is reduced and the energy cost for transportation of wastes-bottles to the dump/landfill is reduced
Well I think in the long run this isn't going to reduce waste-bottle dumping because it only looks practicable in "Slums" , whose inhabitants translate to what in global population? maybe some 0.0x% (iii) it empowers individuals installing the solar light bulbs to generate income (electric bulb makers are large corporation not individuals).
What is ur defination of "individuals" when millions of people not having a roof directly above them cannot use this? Milions of people living under storey buildings cannot use it.
Other indirect benefits include less green-house warming (think about the production processes used for electric light bulb production, the CO2 from electricity generation, and the CO2 released during transportation of wastes bottles to the landfill).
Are you sure about no production of CO2? What does the plant powering the machines fot producing the plastic bottles releasing to the atmosphere? Except the plastic bottles are natural too, just thinking!
Young Nigerians need to learn to think holistically, so that they do could better than their parents who successfully put the country in the mess that it is in now.

Black Peni5: WTF...What's the use of a light bulb in the afternoon when you could just open the windows.
