mg - the ceramic filters you are talking about clearly DO NOT EXIST, from what the story says. They are a blue-sky idea that has never yet been tested experimentally, let alone put into production.

The Fukushima workers need to deal with tens of thousands of tons of dangerously radioactive water RIGHT NOW. They can't wait 20 years for the perfect product, nor can they afford to move in shiploads of stuff that has no proven record of doing anything at all (like hemp or volcanic ash).

Your speculations are offensively condescending.
