According to Blazing Tube Solar's website, the Sol*Saver Water Pasteurizer is a rugged and easily transportable unit. Equipped with eight 22 oz. stainless steel bottles, the user simply fills the bottles with water, closes the cap, snaps them into the unit and closes the transparent lid. All that remains to be done, is to wait until built-in thermal indicators record that pasteurization temperature has been reached.
Once finished, the stainless steel bottles (themselves disinfected in the process) are allowed to cool and will provide long-term sanitary storage of the disinfected drinking water. Using drinking water out of the stainless steel bottles avoids the potential for recontamination, often a risk encountered with batch type solar pasteurizers. On sunny days, several heating cycles can be achieved, providing a multi-day store of reusable, easily transported water bottles.
