University of Rochester scientists have created a metal that is so extremely hydrophobic that the water bounces on it. They used lasers to etch a nanostructure on the metal itself rather than using chemical coatings.
AlgaeBulb lights up with green algae
Algaebulb
Designer Gyula Bodonyi has harnessed the power of green algae in a light bulb. Algae projects have already been seen powering power entire buildings, but Bodonyi’s concept brings green power to the public on a more user-friendly scale. With the Algaebulb, algae powers a single LED activated by a tiny air pump and hydrophobic material able to create a teeny-tiny power house for light. (photos)
