Boom for Location Based Service in China

China’s location-based services (LBS) market boasted three to four million active users by the end of the third quarter this year. China is already home of more than 30 LBS companies, many of which are growing at a decent clip.

As has happened in the US, Chinese businesses are trying to take advantage of location-based networks to promote their products. On its debut in May, Jiepang signed a deal with a café chain in Beijing to offer users free coffee the first time they check in at one of the stores. The site has also joined up with more than a thousand group shopping websites to help users enjoy bulk purchase discounts on a variety of goods.Currently, around 18 percent of China’s estimated 800 million mobile users are using smart phones, a number expected to grow at an annual average rate of 35 percent in the coming five years.

A location-based service (LBS) is an information and entertainment service, accessible with mobile devices through the mobile network and utilizing the ability to make use of the geographical position of the mobile device .

LBS services can be used in a variety of contexts, such as health, work, personal life, etc. LBS services include services to identify a location of a person or object, such as discovering the nearest banking cash machine or the whereabouts of a friend or employee. LBS services include parcel tracking and vehicle tracking services. LBS can include mobile commerce when taking the form of coupons or advertising directed at customers based on their current location. They include personalized weather services and even location-based games. They are an example of telecommunication convergence.

Ground-Source Heat Pumps:Air Conditioners in Reverse

Our quest to find alternative sources of energy is leading us to new frontiers.Ground-source heat pumps (GSHPs), often called “geothermal heat pumps,” are devices to exploit the relatively stable temperatures found just 5 feet (1.5 m) or more below the surface, either depositing or extracting low-intensity heat. Heat pump are basically air conditioners that can be run in reverse to provide heating as well as cooling.

GSHPs should not be confused with geothermal heat, which lurks roughly six miles below the surface, where the earth’s crust gives way to a layer of molten rock. This geothermal energy occasionally explodes to the surface as a volcano, creates natural geysers and hot springs, and, in places like Iceland, it is tapped to produce electricity.

Some Great Stadiums of the World

Croatia Gospin dolac
When it comes to sports stadiums, does it get any more picturesque than this? Gospic Dolac is home to the NK Imotski football club in Croatia and the 4,000 spectators that its bleachers hold get stunning views of nearby medieval ruins, the hillside and the Blue Lake. Gospin Dolac was built in 1989 and is situated next to a 500m deep fall into the lake.

World Games Stadium
Taiwan has what is being touted as the largest solar-powered stadium in the world, the ‘World Games Stadium’. It comes with massive and gigantic solar panels which harnesses all the solar energy in order to generate electricity that could be used by the stadium. It has a 14,155 square meter roof and it harnesses about 1.4 gigawatt hours of electricity every year. When the stadium is not being used, 80% of the neighborhood around the stadium can also be powered through the electricity generated by the stadium!

 

Marina Bay
The Float at Marina Bay, also known as Marina Bay Floating Platform, is the world’s largest floating stage. It is located on the waters of the Marina Reservoir, in Marina Bay, Singapore. Made entirely of steel, the floating platform on Marina Bay measures 120 metres long and 83 metres wide, which is 5% larger than the soccer field at the National Stadium. The platform can bear up to 1,070 tonnes, equivalent to the total weight of 9,000 people, 200 tonnes of stage props and three 30-tonne military vehicles. The gallery at the stadium has a seating capacity of 30,000 people.

 

Vesturi a Eioinum
Vesturi a Eioinum Stadium is a multi-use stadium in Vagur, which is one of the larger villages in the southernmost island Suduroy in the Faroe Islands. It is currently used mostly for football matches and is the home ground of FC Suduroy, former called VB Vagur (until 2005) and VB/Sumba (until 2009). The stadium holds 3,000 people, but has only 330 seats. The Faroe Islands are an island group situated between the Norwegian Sea and the North Atlantic Ocean. Their national football team’s stadium is located next to the sea. There’s a guy in a boat that collects the balls that fall into the sea during a match.

Sapporo Dome, Japan
Sapporo, Japan gets so much snow every year that engineers faced a dilemma in designing a stadium for the city: how could they ensure that the grass playing field would get enough sunlight without using a retractable roof, which may not hold up to 20 feet of frozen precipitation? Their solution was 8,300-ton field that slides in and out of the flying saucer-like stadium, allowing it access to fresh air and sunlight on nice days. This moving field also enables the stadium to switch between baseball and soccer.

NASA’s Mars Rover to Zap Rocks With Laser

A rock-zapping laser instrument on NASA’s next Mars rover has roots in a demonstration that Roger Wiens saw 13 years ago in a colleague’s room at Los Alamos National Laboratory in New Mexico.The Chemistry and Camera (ChemCam) instrument on the rover Curiosity can hit rocks with a laser powerful enough to excite a pinhead-size spot into a glowing, ionized gas. ChemCam then observes the flash through a telescope and analyzes the spectrum of light to identify the chemical elements in the target.
