solar water distilling with fresnel lens

In this video we use a linear fresnel lens to boil and distill salt water into drinking water. The goal is to use this simple technology to help people who don't have a clean water source, or live near the ocean and need to desalinate water for drinking and cooking.

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.

Needs a condenser coil.

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.

Interesting.

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..

how long did it take him to make a cup of water was it 15 mins?

[MrVic1954]

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:
