Nope it's a rectangular magnifying lens made by etching multiple concentric rings in the plastic which will distort light and magnify the object on the other end. They used to have this for TV sets so people with vision problems can see TV by having it in front of their set.
hoverbored, You don't really have to do the ultraviolet step with the clear bottle, I was just taking the extra precaution. Boiling should be enough. I kept it simple to make it easily reproduced in other parts of the world. A black metal pipe would certainly work, but you would probably not be able to monitor the boiling and keep it in the sweet spot of the focal point.
Hey, great video... Why first heat in the clear, THEN move to the darker bottle? Wouldn't it go faster to boil in the dark bottle from the start?
Wonder, too, if you could use metal black pipe as your boiling vessel? Might use a 1-way valve to encourage a flow, and get a (gravity driven?) constant process going? Can't wait to see the wind experiments!
Needs a condenser coil.

put a damp cloth over the pipe to cool it off. This will allow the steam to condense into water before it hits the end, making it more efficient..

Isn't that lense a piece of plastic with a magnifiying glass in the middle of it?

Nice video, but it seems very similar to:
