Dr Rospendowski, can you be more specific in your question.

Yes sat phones charged by a solar array are in use in various locations and there are wind up / hand magneto torches. I have not heard of a specifically solar powered sat phone, and I am not sure this would have great demand, when a standard portable solar charger / array can serve sat phones and multiple other standard kit. What do you hav in mind to 3D print for reconstruction ... time is of the essence, plus quantities. Emergency reconstruction is ttpicallly quite fast and dirty, with emphasis on providing at a minimim standard, to acceptable quality of shelter / reconstruction on a large scale. What will be 3D printed ?? on what scale, how many printers to mobilidse ??.

What types of dyes are being considered and what are the possible side effects on people and habitat, accomodation, etc. Bear in mind the problems of evapouration from dams which concentrate salts and then very adversely affect possible crop production from water with increased salinity and mineral concentrations ... many studies have been done on the destructive effects of evaporation from dams on salt concentration causing long term damage to arrable lands downstream.

What do you hav have in mind to 3D print for reconstruction ... time is of the essence, plus quantities. Emergency reconstruction is ttpicallly typically quite fast and dirty, with emphasis on providing at a minimim minimum standard, to acceptable quality of shelter / reconstruction on a large scale. What will be 3D printed ?? on what scale, how many printers to mobilidse mobilise ??.
