Clean water with a tea bag – South African style

Clean waterI’ve been looking at water purification innovations  and am proud to announce that Stellenbosch University has developed a nifty little device based on  the same material used for the tea bag that is used for a local herbal infusion favourite – Rooibos (Redbush) tea. With added nano-technology goodness.

Yes – it’s a teabag that works in reverse.  Inside it are very thin nanoscale fibres that filter out contaminants as well as bacteria-killing charcoal.  Learn more about it here, here, here and here. And video goodness here. I’ll put the kettle on.
