New solar autoclave

The autoclave uses steam to kill bacteria. Water needs to be heated by electricity or burning fuel, which may be rare in poor areas. The new solar autoclave is equipped with a storage tank that releases water into a set of pipes. The pipe is connected to the copper board with copper board black coating on the surface of the heat-absorbing. The surface is also covered with transparent silica-based aerogel to allow sunlight to pass through. Polished aluminum mirrors on both sides of the plate also help to gather sunlight. When the plate gets hot, the liquid water in the pipeline will turn into steam and reach the autoclave.


The small version of the new solar autoclave equipment was tested in Mumbai and can operate normally in cloudy skies. A solar collector of about 2 square meters is enough to provide the autoclave with the same size as most doctor's offices.
