Material Converts Solar Energy into Steam

July 21, 2014 2:49 pm | by MIT, Jennifer Chu | News | Comments

A new material structure generates steam by soaking up the sun. The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water.When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam.
