Miracle or usury?

You can fool some of the people all of the time,
and all of the people some of the time,
but you can not fool all of the people all of the time.

(all. Abraham Lincoln)

Due to the incredibly fast technical and scientific progress, it has become almost impossible for the average consumer to discern between effective and ineffective products. For example, out of 98 German suppliers of devices for physical water treatment, only 9 proved to be effective according to the German Technical and Scientific Association for Gas and Water,  DVGW (W512, tested at the “Technologiezentrum Wasser” in Karlsruhe, January 2003). I want to present a short overview of the actual research on the presently very popular so-called “Grander water” (“Granderwasser”). Besides drinking water sold in bottles, also technical devices are offered, pretending to improve tap water quality, and attributed with a number of “miracle effects”, including medical ones.

Here in advance a short abstract of the results of my scientific inquiries:

  1. Grander water does not have any effects beyond normal tap water and/or beyond human imagination.
  2. The so-called “Grander technology” used for “vitalization” of tap water is ineffective.

This website gives an overview on the pretended working principle, the pretended effects, and the research about them in different scientific studies. Use the menu to the left to access the different topics.

Have fun and enjoy reding!
