Scientists developing a seawater-desalination chip

Although various alternative technologies are being developed, the large-scale desalination of seawater typically involves forcing it through a membrane that allows the water to pass through, but that traps the salt. These membranes can be costly, they can get fouled, and powerful pumps are required to push the water through. Now, however, scientists from the University of Texas at Austin and Germany’s University of Marburg are taking another approach. They’ve developed a chip that separates salt from water.

New type of silicone exhibits both viscous and elastic properties

Looking for a more effective solution to the all-too-common wobbly table dilemma than a folded up bit of cardboard or piece of rubber under the leg, University of Virginia physicist Lou Bloomfield created a new type of silicone rubber called Vistik – it's malleable enough to take on any shape when pressed, but is still resilient enough to offer support, as it gradually starts to return to its original shape as the pressure is released. The material could have many applications ... beyond just steadying up wobbly tables. Vistik is a viscoelastic material, meaning that it exhibits both viscous and elastic properties. As a result, when compared to something such as conventional silicone rubber, there’s a considerable time lag in its response to continuous pressure. “It seems elastic in response to sudden forces or impacts, denting in proportion to the sudden, brief stress and then returning almost instantly to its earlier shape when that stress is removed,” Prof. Bloomfield ex...

Wired wood: Gizmag's top ten wooden gadgets

We may be surrounded by gadgetry clad in shiny aluminum and gaudy plastic, but there's still a place left in the digital age for the comfort, simplicity and beauty of wood. Perhaps its the trend towards a "green" aesthetic or some deeper drive to get back to nature, but we've noticed a growing number of consumer electronics offerings in recent times that mesh circuit boards and synthetics with the wonders of wood. With this in mind, we've scoured our resources to come up with this list of Gizmag's top ten wooden gadgets. OOOMS Wooden USB Stick OOOMS, a design company based in The Netherlands, has created a USB stick that is made of … a stick. The creators literally pick up sticks, based on quality and appearance, and professionally work them into unique USB sticks that can hold from 2 to 16 Gb. Wooden Records Amanda Ghassaei has developed a laser cutting system that can carve music into a wooden record . After pulling audio from a WAV file with P...

Recycled, solar-powered, boat-roofed wonder wins Shed of the Year

The crowning glory is a 14-ft boat which has been left whole and inverted to form the roof. A 20-W solar panel powers the creature comforts inside. To create the shed's frame, the boat was fixed atop four telegraph poles plonked judiciously on a hillside amid Wales' Cambrian Mountains. (The views aren't at all bad, either). Aluminum-framed windows were salvaged from a 1940s caravan, and others were "borrowed" from Holland's farmhouse. Walls are a mixture of corrugated metal and, for a taste of the Neolithic, wattle and daub. Inside things take a turn for the high tech. The shed's PV panel feeds a battery which provides power to LED lighting and a 12-V sound system – the only new item in the construction. The shed also boasts a plumbed Belfast sink (the generous, cuboid-shaped ones), and a 19th century wood burning stove for heat fitted with a chimney fashioned from the queen pole of an old circus big top.Where sheds end and (sometimes pretentious) ...
