And A good Saturday afternoon to you my freind, message received and noted, excellent range of pictures and comments. Quick question, are the Japanese able to provide any 'testimonials' from the building owners, councils or 'others' to support our marketing campaign?
How do we get some more info on those 'tiles' that allow the water to permiate? Obviously the first part of the rain washes the residue off but I'm not sure why they want the tiles to allow the water through, is it to reduce the run off back into the drainage system? If you have any more info here that would be very helpful.

Ian: TiO2is not harmful to health by the verification of American Food & Drug Administration (FDA) and further certification through application as food additive in various industries.
1. Food industry:

food processing :as white additive color substance?

food freezing :used in freezer & cold storage car through TiO2 air convection treatment machine. It may effectively restrain acetaldehyde consistency to prevent the fruits & vegetables in the freezers & cold storage cars from early ripe & rotting. And prolong their fresh time.

2. Every day life commodities : cosmetics: isolating cream, UVA prevention make-ups, restraining UV in the sunlight from activation to avoid its direct contact with the skin?.
3. Medical industry: internal medicine (for stomach) and anti-cancer (photochemical method).
4. Aquaculture: fish cultivation and nursing room ?the effect of killing germs & killing algae?.
5. Light catalyst: oxyhydrogen gene (OH) produced by TiO2on accepting light has reacted with the organic material in the air and non-poisonous inorganic material is produced.
