Submission + - A Solar-Powered 3D Printer Prints Glass from Sand (thisiscolossal.com)

Tx-0 writes: From the article:
Industrial designer and tinkerer Markus Kayser spent the better part of a year building and experimenting with two fantastic devices that harness the sun’s power in some of the world’s harshest climates. The first he calls a Sun Cutter, a low-tech light cutter that uses a large ball lens to focus the sun’s rays onto a surface that’s moved by a cam-guided system. As the surface moves under the magnified light it cuts 2D components like a laser. The project was tested for the first time in August 2010 in the Egyptian desert and Kayser used thin plywood to create the parts for a few pairs of pretty sweet shades. But he didn’t stop there. Next, Kayser began to examine the process of 3D printing. Merging two of the deserts most abundant resources, nearly unlimited quantities of sand and sun, he created the Solar Sinter, a device that melts sand to create 3D objects out of glass.

Submission + - New quantum record: 14 bits! (nanowerk.com)

Tx-0 writes: Quantum physicists from the University of Innsbruck have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With this experiment the scientists have not only come closer to the realization of a quantum computer but they also show surprising results for the quantum mechanical phenomenon of entanglement.
By now the Innsbruck experimental physicists have succeeded in confining up to 64 particles in an ion trap. "We are not able to entangle this high number of ions yet," says Thomas Monz. "However, our current findings provide us with a better understanding about the behavior of many entangled particles." And this knowledge may soon enable them to entangle even more atoms.
