Interesting Cost Free Daytime Lighting Idea

Recommended Posts

I can imagine some problems with this system, but it's not a bad idea.

Free lighting indoors during the daytime, without opening any skylights or windows.

A good video of an interesting idea.

As some of the comments on YouTube say, though, the poster's username is a bad choice especially if he/she wants the video to be spread around.

I was going to email a link to the video to a few friends, but, given the YouTube username, I'll probably give it a miss.

The selling point is the negligible production cost, using a bottle and water. I'm guessing a light tube costs more.

However, I do wonder how long the water can last before it clouds up and darkens. Or does a little chlorine in an airtight container do the job for years?

If truly viable, I'd probably put one of these in a garden shed or garage etc.

No idea why he chose such a daft username btw.

These chumps have clearly never heard of Velux. Look much nicer too. You can get wee blinds for them and everything.

Yes, it's clearly a grotesque waste of old drink bottles when they could just have gone for one of these in the first place:

Not sure about that. Too much glass. Would be far too hot during the day.

ahem, I think a few here are missing the point of the bottle and water. It spreads the light, rather just letting in a narrow section of it.

And no I don't think they can afford a proper skylight, even if it did the same job :lol:

So to summarise:

A. spreads the light

B. almost cost free to produce

C. cost free to run

D. recycles unwanted plastic

And if you don't like that summary, sod off ;)

It is a corrugated roof - you can get corrugated plastic - a few small sections will do the job better than the bottle.

I'm only guessing but, I think the water in the bottle focuses the light without acting like a greenhouse thus getting light without additional heat which I think sheets of plastic will do.

Why the negativity? It's a brilliant idea. I guess the chlorine is to stop the algae forming and it lights the whole room much better than a clear plastic roof tile would. Credit where it's due.
