College student invents cardboard vacuum cleaner

Enlarge

(PhysOrg.com) -- In another attempt to reduce the amount of plastic refuse that winds up in landfills, Jake Tyler, an industrial design student at Loughborough University has devised a means to construct a working vacuum cleaner out of corrugated cardboard. The vacuum, developed as part of his final year degree project in conjunction with a design team from Vax, where Tyler is now employed, has its housing made of cardboard, while the inside motor works employs recyclable pure nylon plastic using rapid process manufacturing, rather than injection molding.

Called the Vax ev, the cleaner is designed to be assembled at home by the customer using the cardboard from the box in which it is shipped. The cardboard is pretreated with fire retardant, and because it is the corrugated variety, it is assumed it will be able to withstand the rigors of home vacuuming, though, it isn’t clear just yet how long such a vacuum cleaner would last. In its favor, the entire housing can be easily and cheaply replaced, and customers with some foresight might in fact purchase some extra corrugated cardboard from their local packaging store, along with their new vacuum and then use the original panels as a pattern for fashioning their own replacement panels thus avoiding having to go to the manufacture when their new vac runs afoul of some heavy furniture or perhaps a bit of a liquid spill.

Vax, the U.K.s leading floor-care brand says that the new model will be a limited edition, as it’s uncertain just how many customers would actually buy such an appliance.

Royal College of Art student make a 3D printer that focuses the light of the sun

(PhysOrg.com) -- 3D printing has been around for a few years. If you hooked it up to a solar panel you could make it work with the sun, but still would not be as cool as doing it the way that Markus Kayser, a MA student at the Royal College of Art, has gone about it. He has create a 3D printing machine that is able to focus the rays of the sun through a glass ball with enough intensity that it can create a beam that is able to heat silica sand to its melting point. Silica sand is often used in manufacturing process of heat resistant products for its high melting point.

The device, named the Solar Sinter, is based on a previous design known as the Sun-Cutter, which was able to cut two-dimensional shapes into thin sheets of plywood. Because of the imprecision of the tool it was only able to make relatively rough cuts, and there was a great deal of variation in functionality based on changes in the cloud cover.
