MIT Develops Brilliant Graphite Sponge that Converts Solar Energy into Steam

MIT Develops Brilliant Graphite Sponge that Converts Solar Energy into Steam

Until now, solar-powered steam generation has required large-scale systems of mirrors or lenses to concentrate sunlight. Newer methods using nanoparticles have required intensifying solar energy to about 1,000 times a normal sunny day. However, the graphite sponge system only requires about 10 times the intensity of a regular sunny day, drastically reducing the costs and infrastructure required. The graphite component of the sponge is also created in a cost-effective manner: graphite is simply placed in a microwave and “exfoliated,” bubbling up to form a nest of highly porous flakes.
