Long ago there was News!

Long ago, actually more then a year I wrote my last News. Too bad as there was plenty to tell. I also wrote plenty in diaries and reports that I could have posted here at this very place.
But doing so was that one extra thing that did not happen. Reason was real complete involvements in two develoments.
First the Hy2U for washing hands. I was dissatisfied with it being not easy enough to make and that it still was incomplete in its functioning. The drain for collection waste water was missing. Being not happy with a design I made sometimes helps. It resluts in constant poking for a better solution. That soluron slowly came of this last year. Shortly I will publish about it at this site and at the site www.hy2u.org.
Second was the work I did together with my colleage Bram de Vries on the rope pump in a small village in Ethiopia. The target was Demotech-like: cost locally affordable with ease and some real innovative improvements to make future users as enthusiastic as people in the Netherlands are about the new iPad or Androit.

Two weeks ago I came back from Guatemala. At last I was kind of satisfied with the results. Cost is as low as it should be. Promise for new and exiting functionality certainly is there. Most important: the quality of the construction is catching up. It was not very robuust, but it is now. And ideas for even better parts are emerging.

Lots to do before I go back to Guatemala around July. I'll give an update of what had been achieved and what further progress should be got. Specially the work on water tanks holds innovative promises. This News is just for catching up and saying sorry for neglect. More is to come soon!
