| Water thanks to the sun...Magic ? |

Jan de Koning is the inventor. An atypical man as one likes to meet during a trip. His simplicity and his approach bluffed us ! After 25 years at Dupont de Nemours as a team of 100 people manager, he decided to change his business, to make progress, as one can say ! He then started thinking about a low cost machine, and autonomous in energy, which could desalinise the sea water in an efficient way. He started studying the existing systems, most of them coming from a model worked out by a Scandinavian engineer at the 19th century. He then sells everything, keeping only his boat which has become his house, putting all his savings in the development of his mini desalinisator. A traditional solar desalinisator works in the following way : The salted water is heated by the rays of the sun, and is being separated in 2 parts : salt and vapour. The vapor is being recovered when being cooled, and then it can be drunk without any problem. 4L of pure water are recovered with 100L of salted water. After many researches, he applied for 2 patents in order to improve the existing process, one consisting in separating the heating room from the salted w and the cooling room from the vapour. The other one consists in an irregularrunning of the ventilator transporting vapour in the cooling room. And there you have it, his system produces 40L of pure water with 100L of sea water! 10 times more than the previous system... without any maintenance. To support the marketing at the end of the year, a rich Dutch industrial invested by taking 20% of the shares and agroup of 6 experts in various fields joined him. Objective : first desalinisato installed at the end of 2008.To distribute his invention as largely as possible he is doing his best to sell the system at less than 1000€. A good example of a solution financially viable which brings a great advantage to the inhabitants of the poorest countries, in full dryness. We are of course very impressed of the : I leave everything to be finally usefull ! Shake Your Planet
 Jan de Koning, the inventor in his small office bought with his savings 5 years ago.  The workshop of his first tests in 2002  The curve of the evaporation water according to the temperature.. Its system is working when the salted water is heated with a temperature of approximately 80°C. Collectors help the rise in temperature of salted water..  The current pilot on which the tests are done. (the enlightened cylinder including blacks tubes inside) A new and last pilot is coming in 5 weeks. Last step before marketing. |

Bonjour, j'ai 15 ans et je trouve ça fantastique, c'est une invention qui pourra aider des peuples pauvres sans eaux potables et ça fait longtemps qu'il en faut une !! J'espere simplement que vous allez les mettre en vente à bon marché. Franchement je vous dis respect et surtout félicitation à Jan de Koning. |

Bonjour, |
|
comme ils le disent dans l'article l'eau est pure et on peut la boire sans problème. Le fait qu'il n'y ai aucun minéraux n'est pas toxique pour le moins du monde, c'est juste que l'apport en minéraux n'est pas fait par l'eau... |
