Is SODIS just as effective with glass bottles as it is with clear plastic PET bottles?
Generally speaking, glass bottles will work for the SODIS process although they are much thicker walls and generally do not allow as much UV radiation through as thin walled clear plastic PET bottles which are the container of choice. The main disadvantages of glass bottles are the weight and the fact that they can break if dropped. They are also not as plentiful in the rural areas of developing countries where this process is being targeted at the household level. Another disadvantage is the lack of screw top lids found on plastic bottles. They are more difficult to cap and prevent leakage during the process.

What are the main advantages of aluminium water bottles?
I think most people would agree that some properties of a good water bottle are physical durability, and ability to resist corrosion (the corroded material would surely contaminate the water inside the bottle). Aluminium, like most metals, is rather strong. If strengthened with other materials, it should easily resist hard knocks, for example. Also, aluminum has a protective outer layer of aluminum oxide, Al2O3. Said oxide protects the aluminum from oxidation, and prevents exposure to water, which would otherwise lead to a rather vigorous chemical reaction. It can thus be concluded that the aluminum used to make the bottle is almost impervious to corrosion.
