Eliminates all harmful microbes, chemical contaminates, salt, minerals,
and any other impurities from any type of water using only the free evaporative power of the sun
Introducting the new ClearDome Solar Still personal Water Purifier, in two sizes.
It's now available for making delicious ultra pure solar distilled water from any water source. 
The retail price of the large two person solar still (seen on the right) is $495. The small still (seen below) sells for $385.
The stills come in two boxes with a three gallon foul water container, three gallon pure water dispenser, connecting plastic tubing, foul water trays and unique solar fluid heat absorber, and directions with technical details for setup and use are normally emailed in advance of delivery.
All plastics are unbreakable, non-toxic, add no taste to the pure water and are
FDA approved. The stills are shipped collapsed and about 1-2 hours of assembly is required before use. The shipping cost shown is only within the USA, so for overseas and Canadian shipments you'll need to ask for
an estimate to your country.
Look carefully in the photos below and you'll see the pure vaporized water forming and dripping inside just like the natural rain cycle, but without impurities like those found in earth's atmosphere.
The photo above shows the first complete stil system prototype test in progress. The still box had only been closed 20 minutes before the photo was taken and the first condensation is already visible on the sides of the still.
The foul water gravity feed container is seen on the left side, and on the far right the pure water drains down through an inline activated carbon filter to the pure water container on the ground.
An elevated platform or table will be required for the still to allow the pure water to flow downward into the polycarbonate three gallon pure water container.
Only the sun's pure and free energy warms the specially designed dual surface internal fluid heat absorbers inside the dark foul water pans. The fluid heat absorbers quickly
heats any temperature water up to 110-140 degrees F and keeps it there all day in full sunlight. Inside, the normal water vaporization temperature is about 45 degrees F hotter than the outside air
temperature.
It's so efficient that solar distillation is still possible on partly cloudy and light overcast days. About 1/4 of the pure water produced each 24 hour day is at night after the
sun sets. Stored heat inside the still helps to continue distillation process but at a slower rate.
Boiling water to obtain the purest evaporated h2o is less effective than solar distillation because some chemical pollutants, and compounds will vaporize at higher temperatures above 200 degrees F but not at the lower solar still temps.
On Earth this is how all of our pure water is naturally made every day since Earth began.
The process starts with the evaporation of water from the surface of the ocean, plants or other bodies of water.
As moist air is lifted, it cools and water vapor condenses to form clouds.
Moisture is transported around the globe in clouds and the air until it returns to the surface as precipitation.

the University of Illinois web pages that explain it in more detail using animations.
That same natural process is duplicated inside your solar still, except instead of forming clouds, the water forms on the cool clear 90% transparent surfaces inside the still.
The more transparent the surface, the cooler it will remain because only a small amount of heat energy is absorbed. A cool surface is important because without it, water vapor cannot form.
A number of people have asked about using the still on a boat, and for now, it's not possible because of a number of reasons. The still must be used on a flat, stable and level surface for the automatic foul water gravity feed to flow into the water holding pans inside without
over flowing the pans and contaminating the pure water. For example, the still must remain unmoved during distillation to allow the vaporized water to form properly on the inside of the still. We have a number of ideas for ways to stabilize
the still on a docked boat, but it could be at least a few months or more before the ideas become reality and are tested.
Solar distillation is ultra-pure and always free to use
Solar distallation is by far the most reliable, least costly method of 99.999% true purification of any liquid -- especially in developing nations where fuel is scarce or too expensive. Conventional boiling distillation
consumes three kilowatts of energy for every gallon of water, while solar distillation uses only the free, pure power of the sun. Expensive filtration and deionizing systems are even more expensive to purchase and use, and
will not totally purify the water by removing all contaminants.
No additional heat or electrical energy is required in our still, and even after the sun sets, distillation continues at a slower pace into the night. Recently, we've even been experimenting with a unique optional solar energy booster - using our top quality SolaReflex reflector - to increase the water
vaporization by increasing the temperature on the internal fluid heat absorber. This will add efficiency and increases the amount of daily pure water production.
Absolutely pure water is essential for use in fuel cell power generators, scientific research and many medical and plant uses. Scientists, students and researchers will find our Solar Still Water Purifier ideal for
making consistantly ultra pure h20 from any water source. The lack of inexpensive, drinkable water for people around the globe is becoming a very serious problem, and recent
published stories address the concerns from scientists around the world. click here ·
to read a recent story published in many newspapers and magazines.
This unique triangular shape, wind resistant solar still design has taken over six years to perfect, and it has many new and improved features not found in existing solar distillers-- such as a self-feeding three gallon foul water system that eliminates any risk of contaminating the pure evaporated water.
Instead of daily flushing with 2-3 times excess water that's wasted in traditional solar stills, ours converts all incoming fluid into drinkable water and none is wasted. Foul source water only needs to be added every 2-3 weeks in winter and an estimated 1-2 weeks in summer.
Unique new fluid solar heat absorber increases still efficiency
The specially designed internal fluid heat absorber area is angled slightly towards the sun, and not level to the ground as with most other solar stills. This, combined with the unique triple evaporative surface areas increases
the water evaporation by nearly 200% to increase vaporization for faster and
higher quantities of purified drinking water in a smaller area than traditional large solar stills. As a result, winter and summer water distillation is possible with higher efficiency--even on partly cloudy and light overcast days.
This closeup view of the pure water drops forming and dripping also shows a side view of the inside of our unique solar still. It's a completely new design compared to the traditional solar still that has a bottom basin filled with foul water and only a slight incline of the single clear pure water
condensation surface. Ours has a front and back side, (seen in back view photo below) and two side surfaces that combined, rain more than twice the pure water than an equal sized basin still.
Most expensive high energy consumption filtration water purifiers won't remove all toxic chemical contaminants such as precription drug or petrochemical seepage that's been found in many domestic water systems around the world. Solar distillers completely remove
harmful toxins and numerous government and private testing labs around the world have consistantly confirmed this throughout the years. A properly designed solar still is the most reliable way to make any foul water safe to drink. Once the still goes on sale, we will
provide some links to order your own inexpensive water test kits to verify the water purity from your still.
We believe that it is more efficient and more affordable than most other solar stills, and as a result has one of the smallest footprints, measuring only 2' wide x 4' long x 2' tall. It's made for affordable shipping and
portability because of it's light weight at 17 pounds, it's thin size when packed collapsed, measuring only 3" thick and because we use the
best quality unbreakable, testless, and food safe polycarbonate and for the enclosure, and high density polyethelyne plastic for the foul water pans, which only need to be cleaned every 6-8 months or more. Some simple assembly is required before use.
The same design can be scaled up to larger size stills for increased pure water production, but to reduce
shipping costs and to preserve portability, the 2x4' size is more practical for your own use. The 2x4' still is ideal for two people, and a smaller 2x2' still produces enough pure drinking water for one adult or two children.
In the middle of winter, on cool days after freezing nights about 1-1.5 liters (or quarts)
of water are being produced each 24 hour day, and as longer, warmer days approach in summer
we expect increased pure water production to be at least twice as much.
Instead of relying on a single large still for many people, we've designed the large family size still for personal use or for small group use with a small array of stills.

It doesn't matter how polluted the source water is, our unique self-feeding ClearDome Solar Still Water Purifier makes consistantly crystal clear pure drinking water day and night. Included with the still is a round, removable and unbreakable 3 gallon foul water
jug, with a reservoir and tubing to slowly drain by gravity feed into the internal foul water pan as the water evaporates, and a handy three gallon pure water collector that has a spigot for dispensing the newly made delicious pure drinking water. Once the distilled water leaves the still,
the water stays pure on it's way to your mouth because it's never exposed to the open air or dust. We're even included an activated carbon filter to the distilled pure water drain from the still to improve the taste of
severly polluted, smelly water.
Most or nearly all the foul smell and taste will removed from the purified water as it drains into the pure water polycarbonate container, unless the source water is extremely bad smelling.
It's never flat, tasteless water that conventional boiling distillers make because as the water slowly evaporates, it absorbs oxygen before it condenses as pure water on the inside surfaces of the still.
Please don't confuse water Pasteurization (water disinfection with higher temperatures that only kills harmful microbes) or water filtration (reduces many water impurities but seldom all) with solar distillation.
Many so-called "water purification" systems will filter many impurities from water and make it taste better, but most will not
actually completely eliminate every type of combined toxic, organic or chemical contamination. Solar distillation is true water purification.
In the photo on the left, a young Earth Day fairgoer and her dad take a sample of the delicious pure solar distilled water made by our small prototype still at San Diego's annual EarthFair 07. Our Pyramid cooker is visible at the
left side of the still. Large crowds surrounded the still and cooker for most of the day, with most people asking lots of questions, and wanting
water samples to taste. This was the first public demonstration of the final prototype of the still, which is scheduled for the first beta testing
starting between May 15 and May 31. We've had a few delays from some of our contractors that are making the unique plastic forms for the still.
We, and our many taste testers all agree that it's by
far the best testing, purest drinking water you'll ever enjoy. More people in developing nations (over one billion) die of water pollution/contamination disease each year than a lack of food. Our lightweight, unbreakable, shipable
stills will help clean up dirty and dangerous water for them and improve the quality of your drinking water at home to the highest level possible, even more pure than bottled, deionized or filtered water. To learn more about
the proven advantages of solar distillation please do your own Internet search on "solar stills" and to read about the many (over 18 million web pages on Yahoo) university, government and private projects and research papers on solar distillation.
Here's one of the most comprehensive papers written about the evolution of solar stills, including excellent technical information about the different types and performance of the most popular stills by Horace McCracken

And have a look at this web page from AKF Engineers that explains the various types of water purification systems and how well they work. You'll notice that conventional boiling distillation is by far the most reliable, however solar distillation is not mentioned.
Because of the lower vaporization and condensation temperatures, the solar distillation water purity is even greater because of reduction or elimination of harmful gasses.
