Johann Grander (24 April 1930 – 24 September 2012) was the Austrian inventor of a water revitalization technology, which has scientifically been proven as ineffective.
It is scientific consensus that the claims as to how the process changes water are not supported by physics or chemistry and may be called "esoteric nonsense", in the sense of freedom of speech, regarding a verdict of a lawsuit.
Supporters and customers in different professions claim that it cuts the running costs of industry from steel works to fruit canning factories, of public swimming pools, and makes for more effective water-based physiotherapy for injuries.
"[6] In 2006, the Viennese Oberlandesgericht ruled that the claim that seriously ill people may forgo medical treatment and trust in the effects of the revitalized water does not constitute fraud because the vendor guarantees a right of return.
