When it comes to technology, "first," "better" and "stretchier," sets some innovations apart from others. This week, we have the world's first solar power plant (seen here), the most efficient solar cell, the first thought-controlled bionic leg and the first transparent, stretchable organic light-emitting diode, which could lead to stretchy phones. Have a look.
The Ivanpah Solar Electric Generating System in California’s Mojave Desert just came online. Once it's up and running fully, it will generate 392 Megawatts of renewable energy, enough to power 140,000 homes and reduce carbon emissions by 400,000 tons per year.
Mater Dei Supermileage Team
High school students from Indiana's Mater Dei High School in Evansville built a DIY eco-car called Elroy that gets 849 miles to the gallon. Although it's not as efficient as the one students from the Université Laval in Quebec, Canada tested earlier this year, which got 3,587 miles per gallon. That said, the Mater Dei High kids still won the grand prize for their competition, a Duralast 392-piece tool cabinet valued at $2,500. Way to go, kids!
Fraunhofer Institute, Soitec, CEA-Leti and the Helmholtz Center
Theoretically, the efficiency of a solar cell tops out at 33.7 percent. But now scientists from the Fraunhofer Institute for Solar Energy Systems, Soitec, CEA-Leti and the Helmholtz Center have announced that they built a solar cell that's able to convert 44.7 percent of the sunlight hitting it into electricity. The team is not stopping there. They say they want to reach 50 percent efficiency by 2015, and they just might do it.
A new kind of antenna could make it easier to navigate in cities where buildings frequently force GPS signals to bounce around. The VRay, developed by the US Air Force Institute of Technology and the Locata Corp., uses a beam-forming antenna with 64 receiving elements that identify and subtract the numerous paths a signal takes while bouncing around, as well as other forms of interference, and produces a clean signal.

Tiny cage-like structures could work like delivery trucks inside our bodies to deliver the precise dose of medicine to the exact location. The "vehicles" are coated nickel and steered wirelessly by electromagnetic fields.
Anish Kapoor, Arata Isozaki, and the Lucerne Festival
The world's first inflatable concert hall is getting pumped up for a show in Japan in Matsushima, which was hit by the tsunami of 2011. The Ark Nova, designed by sculptor Anish Kapoor and architect Arata Isozaki for the Lucerne Festival 2013, is made from a translucent purple membrane reminiscent of a parachute. It can house up to 500 people. Tsunami-damaged trees will be used to build seating and for acoustic reflectors inside.
Microsoft has unveiled its Surface 2. Two pieces of magnesium sandwich electronics powered by a Tegra 4 chip. The company hopes that customers will respond favorably to the tablet's lighter and thinner design, its full HD screen and camera that's 5 times sharper than in the Surface Pro.
Researchers from UCLA led by Qibing Pei, a materials scientist, have developed a transparent, elastic organic light-emitting device, or OLED. A transparent display that bends could usher in smartphone screens that have adjustable sizes, displays that double as window shades and medical implants and flex with a person’s body.
REHABILITATION INSTITUTE OF CHICAGO
Zac Vawter, who lost his leg below the knee after a motorcycle accident four years, is the first amputee with a thought-controlled bionic leg. The leg has a computer chip that decodes the electrical signals traveling through Vawter's leg muscle and translates it into motion. A motor in the knee and ankle helps him push himself up stairs.
For the first time, scientists have put a kind of tuning fork for light waves onto a computer chip. Just as a tuning fork produces a standardized pitch in sound, this spiral-shaped optical resonator produces a consistent light frequency, or wavelength. Wavelengths correspond to colors in the light spectrum. Miniaturizing a device that's able control the frequency of light could lead to computer chips that use light instead of electrons to process signals -- and that could usher in super-fast computers, precise navigation and futuristic applications that haven't even been imagined yet.
