Ice & frost on airplane wings is extremely dangerous to flying. The U.S. airline industry spends over ~$750M dollars in the winter to chemically defrost their planes to stay on schedule. These de-frost chemicals are environmentally hazardous and must be carefully contained for special disposal or re-use. SolarMelts has designed a spray-able solar activated liquid de-icer, SkyMelt, that is completely bio-degradable. Our liquid de-icer solution can be used to passively absorb sunlight or can be used as a spray-able electrode that can heat surfaces when passing a current through it.
