As a still, it eliminates all harmful microbes, chemical contaminates, salt, minerals, and any other impurities from most water

As a Pasteurizer it kills all harmful microbes in fresh water

After nearly two years of constant testing and multiple design improvements of our first generation solar still, we’re proud to announce that our upgraded and improved second generation ClearDome Solar personal Still/Water Pasteurizer is now available.

We’ve made many innovative improvements on the original triangular shaped still design, shown below, and the more compact, more efficient personal size solar water purifier is now be available to order for only $349 from the PayPal order links below. All you need is sunshine to turn brackish, polluted, salt or most questionable water into delicious ultra pure solar distilled water from nearly any water source.

With a simple modification it will make foul lake, stream or standing fresh water safe to drink by Pastuerizing about 6 times more fresh water at temperatures between 140-150 degrees F.

It is scientifically proven that water does not need to boil to kill the harmful microbes that can make you sick.

In only about four hours of full midday sun, it will Pasteurize up to 6 liters (or quarts) of safe drinking water for medium size family, and it will ultra purify about 1-2 quarts of water for one adult or two children in a 24-hour day when set up for distillation.

First combination Solar Still/Pasturizer

This is the world’s first combination solar still and Pasteurizer in one unit. A photo of one Pasteurizer configuration is shown below. Notice the heating trays have optional clear lids on them and not the fluid heat absorbers used to distill. The clear lids trap heat generated by the sun to boost the water temperatures to over 150 degrees F in about 3-4 hours of full midday sun, hot enough to kill harmful microbes.

Another method to solar Pasteurize is to nearly fill up to six, one liter (or quart) clear drinking water containers with the questionable fresh water and lay them in the solar heating pans inside the still box. In about four hours of midday solar heating, all the harmful microbes will be killed, making the water safe to drink.

In many areas where fresh tap water is questionable or not chemically contaminated, but still unsafe to drink because of microbe infestation, heat treating the water at the proper time and temperature is all that’s needed to make it safe to drink. More photos and more details will be posted here in coming weeks.

The dome-shaped ClearDome Solar water distiller/Pasteurizer is 1/3 smaller (8” tall x 17” wide x 48” long), lighter, more portable and unbreakable, and even more efficient than our previous still. It will include the same automatic self-feeding three gallon foul water container with reservoir, connecting plastic tubing for gravity feed, two internal foul water trays and our unique efficiency-boosting solar fluid heat absorbers.

This is similar to the original system below, but the heat absorber assembly is now arched into a dome shape for quicker, more efficient evaporation. The dome shape of the heating box is very sturdy and has outstanding wind resistance in moderate winds without having to secure it down. The 3-gallon pure water catch container and activated charcoal filter will be optional.

For larger solar distillation or water Pasteurization needs, we are also designing a simple Clear Dome Solar Still Array where multiple dome stills are positioned near each other with connecting tubes that drain to a central pure water storage tank. We’ve had a number of requests from around the world to design a simple, easy-to-use large solar distillation/Pasteurization system for small communities where pure drinking water is scarce or too expensive.

Having two choices for making completely safe drinking water using only sunshine as the power source is a real advantange for most survival and emergency situations. It can also be used for melting snow, re-heating food and to heat bathing and clothes washing water. Smaller quantities of water can be pasteurized even faster than the normal four hours in full sunlight. And soon we’ll be offering a smaller half-size “demonstrator” solar Still/Pasteurizer” for students, instructors, and thermal professionals. It solar distills about one pint of pure water per day.

Our discontinued first generation Solar still is shown on the left. We’ve made a number of important improvements and the price will be lower for the upcoming Dome Still/Pasteurizer.

All polycarbonate plastic parts used in construction of our solar stills and other products are unbreakable, FDA/NSF approved, non-toxic, and make delicious pure drinking water.
