Investigation of Solar Energy for Ice Melting.
The object of this study was to investigate the possibility of melting ice formed on the surfaces of rivers and lakes in the northern parts of the United States by applying a layer of a material that would absorb more of the available solar energy. Heat losses from water surfaces during the winter m...
