From Engadget: Scientists produce stronger T-rays, bring Tricorders closer to reality

A group of scientists from Imperial College London and Singapore’s Institute of Materials Research and Engineering (IMRE) have developed a new technique that could have far reaching impacts for Star Trek fans everywhere. It all involves something known as Terahertz (THz), or T-rays: electromagnetic rays that have already been used in full-body airport scanners and have the potential to be used across a much broader range of medical and environmental applications. Because every molecule can be uniquely identified within the THz range, these T-rays can be used to pick up on cancerous cells and other biological matter, perhaps even within a Tricorder-like scanner. Now, Imperial College’s Stefan Maier and his team of scientists say they’ve found a way to create a stronger beam of T-rays, using so-called “nano-antennas” to generate an amplified THz field. In fact, this field can produce about 100 times more power than most other THz sources, which could allow for sharper imaging devices. “T-rays promise to revolutionize medical scanning to make it faster and more convenient, potentially relieving patients from the inconvenience of complicated diagnostic procedures and the stress of waiting for accurate results,” Maier explained. “Thanks to modern nanotechnology and nanofabrication, we have made a real breakthrough in the generation of T-rays that takes us a step closer to these new scanning devices.” For more details, check out the links below.

From Gizmodo: Latest DIY Destroyer Proves That the Slingshot Master Is Officially a Wizard

As you stretch a rubber band, it heats up. But as it cools down it actually loses some of the energy it stored when it was stretched. That means the longer a slingshot is left loaded, the less powerful it becomes. Unless you’re Joerg Sprave, the internet’s resident master of slingshot design, who discovered that simply reheating a stretched elastic band can restore up to 40 percent of its original powuh.

From Popular Science – New Technology, Science News, The Future Now: Tesla’s Model S Sets a New Standard for Battery-Powered Cars

This is a very welcome news as electric cars lacked one key factor: range. I hope Tesla makes electric vehicles a very welcome category as we need to move away more and more from gasoline powered cars.
=========================================================

Tesla Model S Tesla

Until now, there hasn’t been an all-electric car fit for road-tripping. But Tesla’s Model S, due out late in 2012, is made for extended drives. Its battery goes up to 300 miles on a charge. Its cabin is spacious enough for seven passengers. And it can get up to cruising speed fast-the Model S accelerates from 0 to 60 in 5.6 seconds.

BIGGER BATTERY

At 85 kilowatt-hours, the Model S boasts more than triple the battery capacity of the Nissan Leaf. Its thousands of lithium-ion cells use a new electrode chemistry from Panasonic, which could allow them to store more power than other comparably sized cells.

FAST CHARGE

Tesla plans to install proprietary 440-volt charging stations (first along the I-5 Corridor between Los Angeles and San Francisco) built to match up with the Model S’s circuitry. They will provide a full charge in an hour. Standard chargers will require a full night.

TEMPERATURE CONTROL

To protect the motor, circuitry and battery from heat, channels filled with liquid coolant run through the components. Pumps cycle coolant through a front radiator and a pair of A/C condensers. This helps the motor deliver twice the power of its Roadster predecessor.

LIGHT BODY

To increase the sedan’s range, the designers of the Model S kept its weight low with a body constructed from 97 percent aluminum. They added heavier structural steel only where necessary for safety: in central supports and front-end crash zones.

ROOMY CABIN

The Model S’s batteries sit beneath the floor in a large flat pack that spreads the width of the car and about two thirds of its length. This arrangement leaves ample space in the trunk for cargo or two backward-facing jump seats. The main interior holds five adults.

Top Speed:130 mph
Range: 300 miles
Seats: Five adults, two children
Price: $77,400

From Engadget: BASF, Philips team up to create transparent OLED car roof

If you’re the sort who wished your car had a transparent roof when the rain falls down but want some shielding when the sun’s up (or, you know, vice versa) then BASF have good news for you. It’s showing off the transparent OLED technology it developed with Philips that behaves like glass when inactive, turning opaque when activated. We’re already familiar with the technology here, because it’s the same kit that the chemicals giant showed off on its custom Smart Forvision it produced with Daimler back in September. As before, it’s also been able to pair them up with transparent solar cells, for environmentally friendly sky watching: just remember that people will be able to see you pick your nose from all angles now, okay?

From Technology Review RSS Feeds: Fracking Quakes Shake the Shale Gas Industry

Well shutdowns prompted by fracking-induced seismicity may inspire technology tweaks.

Geophysicists are increasingly certain that expanding production of shale gas is responsible for a spate of minor earthquakes that have upset some communities and prompted authorities in Arkansas, Ohio, Oklahoma, and the U.K. to shut down some natural-gas operations. The question now, say the experts, is whether the underground operations causing the trouble should be scaled back or more closely monitored to minimize future quakes—and whether the relatively small quakes may yet have the potential trigger truly destructive ones.
