A new carbon-based material structure developed at MIT generates steam from solar energy.
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. The brighter the light,… read more
