Thanks a lot Bob. I will surely not stop until I will be able to get this project done. Its getting more interesting (for me) and getting more complex.

2USD may be too low to be possible.

Read up on micro-solar. It’s booming all around the globe. By buying a small system with time payments people are moving from candles and kerosene to LEDs and cell phone charging. While spending less money.

Lots more programs – just google.

And google a device called Gravity Light. They aren’t actually delivering yet but they’ve got an interesting idea for low cost light. (I like micro-solar better. But there’s room to try lots of stuff.)

I am the one not reading well. I was actually thinking of duplicating this stuff if this will work at night and go for mass production but won’t be working. But anyhow, this study lead me to do further research of keeping the sun’s energy which will be illuminated by nightime. Much like a “glow in the dark” stuff but something that is much cheaper which may be brought at 2USD each.

I don’t see that in the text. In one of the videos do they talk about light at night?

But it said that it will be able to illuminate during nighttime. Are you saying that it just get its illumination from the sky? It will not light at all if it won’t reflect from the sky?

It isn’t storing light. It’s just a cheap skylight.

I was wondering why you need to put it in a whole. Why not just something that can be placed under the sun during daytime and then be brought inside during nightime.

Deck prisms, and skylights, are a bit pricey. This is a very low cost solution.

This idea is by no means “new.” do a simple internet search for the phrase “deck prism” this is technology that has been used for centuries

how do you make this thing we are always in the dark coz of loadshedding

The whole original story I’ve seen (video above) features this Brazilian engineer. I wouldn’t be surprised if diff people discovered/’invented’ the same thing, but as far as I have seen, this guy was the first.

You said a Brazilian Engineer invented this… But other websites say it was MIT students… Who was it? In fact this is the only website I’ve seen that doesn’t mention MIT.

The main “minus” of these sun bulbs is that they do not produce nor accumulate light, they only disperse sunlight so they can be used only by the poorest in the countries with hot climate (no cielings in the houses, only thin roofs)…

Hi guys! Are you all writing these comments too lazy to use your brains? Zachary told you about a program called “a liter of light.”. Does it really take too much intelligence just to google “a liter of light”??? The first search result gives you the answer to the question how it works and how to make such bulbs yourself: http://isanglitrongliwanag.org/ ! You can download detailed step-by-step manual showing it all or watch a film. What do you use your internet for? Just for chatting? Shame on you!
