Hira Ratan Manek (HRM) speaks of the benefits of using sun-charged water. Follow these simple instructions to make your own sun-charged drink.
To sun-charge water, place fresh drinkable water into a clear glass container. The maximum recommended container size is one gallon. Using smaller and/or broader containers provide more surface area for the sunlight to directly contact, thus quickening the charging process.
Cover the clear glass container with a clear glass lid. Do not use plastic, since plastic has been found to leech harmful chemicals into liquid and air.
Place the container in direct sunlight, outside on bare earth. Do not place the container on grass, since grass will prevent charging. If bare earth is not availble, choose a suitable material other than grass (sand, rock, cement, etc).
Leave the container outside for a minimum of 5 hours. Depending on the season and planetary location, a container of water will be fully sun-charged between 5 and 8 hours. Leaving the container in the direct sunlight longer than 8 hours will not harm it.
Do not leave the container of water outside over night. Doing so will quickly drain the water of its charge. In addition, no studies have been done to measure the effects of moon-charged water. Moon-charging water is not recommended, since the moon produces no light of its own and has been shown to adversly affect some humans (lunacy).
Drink the sun-charged water immediatly after it has been fully charged. Sun-charged water may be stored for up to 24 hours. After which time, it should be re-charged in the sunlight. There is no need to refrigerate this water. Science has shown that room-temperature drinking water is the most beneficial temperature.
In addition to drinking sun-charged water, this water can be applied directly to the skin through self-massage, soaks, or compresses. Sun-charged water is also helpful when used as an eye-wash.

The results of each set of experiments have consistently confirmed the fact that the bacteria contaminating water from faecal sources are, as a general rule, susceptible to destruction upon exposure to sunlight for an adequate period of time.
