New Solar Plant Shines Even At Night
It s the thing that seems to bother most people whenever solar power is discussed What happens at night? The most sophisticated solar plants have found ways to compensate for the lack of sunlight during the night by coupling solar plants with other energy sources or by storing some energy during the day to be used at night. But now a new power plant developed by Torresol Energy in Spain has claimed to offer once and for all a reliable 24-hour solution to solar energy.
SETUP AND WORKING :
The Gemasolar plant (above) uses hudreds of mirrors to reflect concentrated sunlight toward a central tower, where water is heated to steam, which drives a turbine that produces electricity.This scheme is becoming increasingly more popular than the traditional photovoltaic (PV) cell systems because of lower costs and comparable efficiency. The CSP systems also have the advantage of being easily integrated into existing power plants that already use turbines.
During the day, energy is stored by heating up large tanks of molten salt composed of a mixture of 60 percent potassium nitrate and 40 percent sodium nitrate. The molten salt is able to retain a very large amount of heat -- enough to drive the plant for 15 hours without sunlight. Although molten salt has been used in other plants to store heat energy, the efficiency achieved by Torresol is new.
PRODUCTION CAPACITY :
The plant has a production capacity of 19.9 Megawatts and although this is relatively small as far as power plants go, the fact that the plant runs continuously means that the effective production is comparable to a traditional 50 Megawatt solar power plant.

Double-Decker Bullet Train Could Speed Through Australia
Australian design firm Hassell has unveiled a concept for a new double-decker high-speed train meant to travel between Melbourne and Sydney. Flying at speeds of 248 miles per hour, the train would make the trip, which is one of the busiest air traffic corridors in the world, in less than three hours.
Hassells design shows a spacious, sophisticated train that has private booths for business meetings as well as dining facilities and a convenience store. Such a train could appeal to commuters, who are tired of dealing with long lines, delayed flights and cramped seating common in air travel.

Turn Your Snapshots Into 3-D Photos
what if you can spin a photo?or you can actually see back of anything
Well, thanks to Sudipta Sinha and his colleagues at Interactive Visual Media, that's now possible. Along with his research team, Sinha helped develop a system that allows a regular digital camera to create a 360-degree, 3-D image from a collection of about 40 ordinary digital photos. The team unveiled the 3-D scanning demo earlier this week at the Microsoft Research hosted TechFair 2011 in Washington, D.C.
Suppose you see something interesting and you want to capture different views of an object from different angles, You take these pictures from different viewpoints, send them to our system, and it automatically figures out a 3-D model by measuring the 3-D depth behind the pixels in the images. Once you have that, you can interactively, seamlessly change the view from one camera location to another, and this allows the object to be viewed interactively in 3-D
The photos get transferred to a PC and uploaded to the cloud, then are processed by a pipeline that matches similar images andlearns how the camera moved in 3-D. This enables the creation of a depth map, similar to the depth data provided by the Kinect for Xbox 360 sensor. The depth data gets stored in a compact format and is then viewable on virtually any screen you prefer: phone, laptop, desktop. .

Climate-Controlled Jacket Keeps You Cool or Warm
When Kranthi Vistakula moved from the sweltering heat of Hyderabad, India, to study at Boston's Massachusetts Instituteof Technology ( MIT ), the frigid East Coast winters gave the young engineer a chilly reception.
Trudging through Boston's sub-zero winters with layers of clothing -- only later to remove those layers once inside warm classrooms -- irked Vistakula. So he created a climate-controlled, all-weather jacket capable of adjusting to extreme temperatures.
The MIT graduate is now CEO of Dhama Innovations , his start-up in Hyderabad that has begun selling Clima Ware jackets and other clothing that allow wearers to control their comfort level without adding or removing layers.
Our products can go from zero to 100 degrees C in the push of a button.We have four levels of heating and four levels of cooling that include low, medium, high and very high.
Despite bulky prototypes weighing over 7 pounds, complete with motorised fans, heating pipes and electric wiring, Vistakula settled on a more streamlined design by using a thermoelectric device called a Peltier plate, which consists of a junction between two different metals. Forcing an electric current across that junction causes the metal on oneside to heat up, and the metal onthe other side to cool down. This so-called Peltier effect also helps cool electronic device such as laptops.
The tiles are powered by rechargeable batteries that can hold 8 hours on a single charge. The jacket weighs just over one pound and can maintain internal temperatures between 68 to 104degrees Fahrenheit and can operate in ambient temperatures between -122 and 122 degrees Fahrenheit. Besides ClimaWare jackets, the company also sells neck wraps, shoes, and bike helmets, as well as knee and elbow packs that provide hot and cold therapy.

Bike Laser Aims to Increase Cyclist Visibility
Hopping on a bicycle saddle and peddling through the heart of the city is not for the faint of heart. Besides being safeguardedby minimal protection amidst aggressive traffic, their slower pace and low visibility often subject bikers to unfathomable road rage and projectiles hurled from angry motorists.
Helping bridge this gap is BLAZE,a device invented by Emily Brooke, a final-year Product Design student at the University of Brighton . Her device alerts drivers to the presence of a bikers by projecting a laser image onto the road in front of the bicycle.
To make bikers more visible, thehandlebar-mounted device projects a bright green, diamond-shaped shared lane symbol on the pavement, severalfeet in front of the cyclist. The symbol, even visible in daylight, can be made to flash on and off.
The idea is that motorists will notice the green image on the road and take precaution, even if they don't see the cyclist in their blind spot.

Apple's Newly Planned Headquarters is Pentagon-Big
Ask yourself, is it good that a company headquarters is roughly the size of the Pentagon? Or should that be a red flag? I jest. Somewhat. But that's basically the size of Apple's new building, proposed by CEO Steve Jobs, although a bitof a smaller footprint overall.
