Does anyone have info about solar water distillers?
Is there a way to purify water using the sun’s energy? An affordable method everyone could have?
Thanks you guys, I’d like to make a miniature one for ALL people to be able to collect rainwater, then purify it. I’ll be researching your ideas.
Yse, Jim, I was trying to open a dialog where someone could come up with a way for peoples around the world to have access to their own drinking water derived from rain water. thank you all who responded, I “lerned” something already. Anyone else want to answer before Jim get 10 points?
Sorry about the spelling errors, everyone.
Water has the highest specific heat of any liquid below the molecular weight of 100 – it really takes a lot of energy to boil water!!! Using solar energy to boil water is certainly possible, but are you really interested in creating drinking water, or distilling water?
Someone in India needed an affordable way to make lots of drinking water inexpensively (I saw this on TV). What they came up with was a “germicidal” UV lamp and a shallow aluminum tray for the water to pass under the lamp, thereby “purifying” the water to drinking water quality by killing all the bacteria.
The germicidal lamp fits in an ordinary fluorescent fixture, and is very efficient on power. His task was to design the parts that would certify that all the bacteria was killed. The design will treat LARGE volumes of water economically; something a distiller won’t do.
One more important point to consider: a true steam distillation process is intended to remove the minerals from the water as well as everything else. You need to think this through very carefully and research what happens when people drink (only) distilled water.
Because of difference between salinity in people’s body and the distilled water, the distilled water will strip the electrolytes (minerals) from your body. This is not a good thing! If you distill the water, you’ll have to add some minerals back before it would be drinking water quality.
This is why the bottled water at the store offers both drinking water (water with small amounts of minerals) and steam distilled water (for your steam iron, where you don’t want any minerals)
One other person in Yahoo! Answers wanted to purify water using UV LED technology – UV LEDs operate at even lower power that UV germicidal bulbs, and could be driven by solar cell/battery combinations. UV LEDs are just now becoming available, and will soon be affordable.
This is assuming that the water you have is drinkable but just needs to be affordably cleaned of bacteria.
Water that is brackish or saline would need to be steam distilled, but that is expensive due to the energy required. There are other water treatments available (osmosis, filtering, dissolved mineral removal such as iron, hard water treatment, etc), but these cost money.

catnip perhaps?

heavy metals will not evaporate at those temperatures, so yes it would remove heavy metals from the water. Its all about at what temperature things evaporate at, some things in water like some toxins, may evaporate at the temperatures reached in the solar distiller, this kind of distiller is good for emergency purpose, I wouldn’t use it for regular use, there are plans for large glass units available on the net.

Yep, the trick though is to keep the temperature at a point that evaporates alcohol more efficiently then water. higher grade alcohol is obtained by passing it through the distiller more than once ( removes more and more water.) solar would not work well, because it would be difficult to control the temperature.

Thanks Gilgamesh. I didn’t realize flouride won’t evaporate. My research showed me that water distillers DID get rid of the flouride. Maybe not THIS one, but other claimed they did. I guess I have more research to do. Thanks.

Excellent presentation. Love the cat! Particularly, I like how the narraration takes in stride that the feline is trying to steal the show (or, at least the parts).
Virtual fist-bump for job-well-done.

Next time, use urine as the water you start with. Show how it can also be made drinkable.

hahahaha, you should get also a bulletproof vest. I think we’re gonna need experiments like this one, sooner than we thought. Not really sure about the soil question. Maybe it just changes the taste of the water.

i think if u had a liquid with a higher boiling point that to water and was poisionous it might filter out depending on the heat of the day, its jusrt a thought if u want to try it

we watched this video in my grade 8 science class hahaha and i was like thats zack scott and everyone was like who?

Isn’t aluminum linked to Alzheimers and plastic bad for you as well??? Is there anything else you can use to replace these items?

just so you know dirnking to mutch off that water is danguros

NICE!

@emmagr1002 maybe he was sick

look at the cat just chillin

@Gokill2 Explain.

hold on a sec can i distill alcohol this way too?

I will try pee, myself.

@SavageArms357 the destiled water will have no salt & minerals in it and so if you drink to much you will get a lack of salt & minerals and may kock you unconsius

@Gokill2 I suppose extremely long term drinking of it wouldn’t be good.
