Great use for recycled plastic bottles

A cheap, low (er) tech version of solar tubes! Two thumbs up!

Does the bleach just keep the water from going bio or does it give some extra fluorescence to the bottle?

Ver cool. I may check out the link and send a little of my money their way!

Pretty sure it's just to keep the water from turning cloudy. I do wonder how the light output is impacted over time as the outdoor part of the bottle gets scratched and scuffed from exposure.
Light + water = algae

Bleach probably keeps algae from growing in the bottle.

That is all great, but if you want to move over water...

Imagine collecting thousands of empty plastic bottles, lashing them together to make a boat and sailing the thing from California to Australia, a journey of 11,000 miles (17,700 km) through treacherous seas.

You'd have to be crazy, or trying to make a point. David de Rothschild is trying to make a point.

De Rothschild hopes his one-of-a-kind vessel, now being built on a San Francisco pier, will boost recycling of plastic bottles, which he says are a symbol of global waste. Except for the masts, which are metal, everything on the 60-foot catamaran is made from recycled plastic.

Not bad.
