Cow Dung Boiler : An Emergency Source of Steam
Cow Dung Boiler: An emergency source of steam for solar powered steam pumping systems.

Solution

Solar powered steam irrigation pumping systems, like the Sunflower, are viewed by this participant as an excellent solution for pumping water in rural Bihar India.

A potential issue for solar powered steam irrigation pumps is a prolonged period of clouds. Also, if the parabolic dish was damaged, the time required to repair it could result in crop damage. 

My idea is for the Cow Dung Boiler to serve as an emergency source of steam for pumping systems utilizing steam as its energy source. 

Even if the Cow Dung Boiler was never used, the peace of mind knowing you had an emergency backup plan to prevent disaster would be extremely valuable.
