Horst Walther (هُرست وَلتِر) - water from the air ...

Harvesting water from the air around us is one of my old dreams - but not only mine. The idea was and still is virtually in the air.
To collect the morning dew, which occurs even in many deserts, by the use of an old blanket or a foil is reported to be an old legionnaire's trick: You dig a hole into the ground, put a pot inside to contain the collected water and cover it with a stretched blanket. A small stone put in it's center ensures, that the blanket's lowest point is right above the digged-in pot and the dew drops concentrate here - and drop into the pot.
This little trick was known to the human rights activist and survival expert Rüdiger Nehberg already. However he intended to survive when there was no dew as well.
But what to do if there is no dew? Here the chemist job starts.
During our adventurous trip through the Danakil desert in 1977 (Klaus Denart, Rüdiger Nehberg and Horst Walther) we experimented with the drying agent silica gel and zeolithe. But this methods had it's own specific disadvantages.
Water from the air - this idea also fuelled Frank Thielow's activities. Frank Thielow looking back on a successful professional life as an engineer, inventor, developer and entrepreneur represents the prototype of an Swabian inventor. His engineering firm Logos Innovationen delivered major contributions to many interesting technical innovations and Improvements.
He was the driving force which led to the foundation of the α-spring endowment, which was celebrated at March 13th, 2005 in Bodnegg at the shores of the Lake Constance recently.
The foundations registered capital amounts to 50.000 €. This capital is surely not enough to fund such an ambitious venture. The α-spring foundation therefore depends on additional contributions and donations.
The α-spring technology has matured over 7 years already. In the course of this development they investigated several competing methodologies have been and built a prototype. download the flyer
The Diploma thesis of Stefan Haag in 2004 started the scientific research on this topic.
