Philips Research Laboratories engineers have taken inspiration from moth eyes to develop a coating for solar cells that increases their efficiency. Nanostructures, comparable to the tapered structures on the insects' eyes, reduce the amount of light that's reflected off the photovoltaic material. From Physics World:
To maximize the amount of light entering (moths') eyes, to help them see at night, the insects' eyes are covered in tapered nanostructures. This creates an "effective medium" where the refractive index gradually increases as light travels from air through to the insects' optical nerve. The resulting effective index is close to one, which means that very little light is reflected out of the eye.
Inspired by these biostructures, Gomez Rivas and colleagues have mimicked the effect by growing nanowires of different lengths - creating a metamaterial with optical properties that change gradually as a function of distance.
Never heard of Nibbler? You’re not alone. Nibbler was one of a handful of arcade games produced in the early 80’s by Rock-Ola Manufacturing Company, a company better known for its stylish jukeboxes. Designed by programmers Joe Ulowetz and John Jaugilas, Nibbler is the bastard lovechild of the Pac-Man and the cell phone game Snake, […]
As the former editor-in-chief of the technology project magazine MAKE, I’ve learned that makers don’t limit themselves to simply making things. Their urge to be an active participant in the world around them means that they also have a strong desire to make the tools, processes, systems, and organizations that empower other people to do […]
My wife has been using this wine saver vacuum pump for several years now. It creates an airtight vacuum in the bottle to preserve the wine. The pump comes with two rubber stoppers with one-way valves. You insert the stopper into a partially full wine bottle, then suck the air out with the pump. It […]
