A New Superpower Joins Space Exploration Race - Launch of China's First Space Laboratory Tiangong-1

Today (29 September 2011) at 13:16GMT China successfully launched its first space laboratory module Tiangong-1 from the Jiuquan spaceport in the Gobi Desert in Gansu Province.Tiangong means "heavenly palace" in Chinese.The module was on a carrier rocket, called the Long March 2F T1.This 8.5-ton lab module is a part of the Chinese space exploration program to test a space rendezvous and docking capabilities which will ultimately serve as a stepping stone to developing a manned space platform.

Tata Nano - The World's Cheapest Car

Tata Nano is a low cost,four-passenger and rear-engined car produced by the Indian Automaker Company Tata Motors.This car is targeted mainly at the Indian domestic market.Tata Motors began selling this car in March 2009.It is also known as "one-alkh car",due to its price point near 100,000 Indian Rupees. On-line sources claim that it the world's cheapest city car today.However,the price of this car is continuously rising due to the soaring material costs.

Serafina - The World's Smallest Autonomous Submarine

Deep sea explorations have always been a great challenge to engineers and geo-physicists,both in terms of technology and financial resources required for such explorations.In such explorations, an under water vehicle or submarine (manned or autonomous) is a very important instrument that has a vital role in exploring the vast depths of the oceans.In this regard development of Serafina,the world's smallest autonomous submarine,developed at The Australian National University (ANU) is a great breakthrough.Development of this small and autonomous underwater vehicle is indeed the beginning of a new era of oceanic discovery as this submarine has potential applications in shipwreck recovery,mineral explorations,search and rescue missions.

Nemo33 - The World's Deepest Indoor Swimming Pool

Nemo33 is the world's deepest indoor swimming pool located in Brussels,Belgium.It's maximum depth is 33 meters (108 foot).It is capable of containing 2.5million litres of water.The complex ,which houses this masterpiece of architecture,was designed by a Belgian diving expert,Jhon Beernaert in 2004.It was constructed as a multi-purpose facility for diving,recreation and as a potential underwater spot for film production.The pool consists of a submerged structure with flat platforms at various depth levels.The pool has two large flat-bottomed areas at depth levels of 5m (16foot) and 10m (32foot).The pool also contains a deep circular pit,which is 33m (108 foot) deep.The pool is filled with 2500,000 litres of non-chlorinated and highly filtered spring water maintained at a temperature of 30°C (86°F ).The pool contains loads of cool passageways, rooms and simulated underwater caves at 10m depth level.There are numerous underwater windows that allow visitors to look into pool at various depths.

What is Uninterruptible Power Supply (UPS)?

An Uninterruptible Power Supply (UPS) is an Electrical device or equipment which serves as an emergency or backup power source when the input power supply, usually the utility mains, fails. In addition to serving as a backup power source, -the UPS also serves a “power conditioner” by ensuring that the electricity being supplied to sensitive instruments and devices in your home or office like computer, TV and telecommunication equipment is free from common utility power problems like voltage sag, surge, noise, frequency instability and spikes.

A UPS, unlike an emergency power system or standby generator, provides almost instantaneous protection from interruptions in power supplied to the electrical load or device from utility mains. For low power electrical devices or loads the UPS provides this protection through one or more attached batteries and electronic circuitry. While for high power electrical loads this protection is provided by the UPS by means of diesel generators and flywheels.

Broadly speaking there are three common types of UPS: On-line UPS, Line Interactive UPS and Standby UPS. However, many manufacturers categorize UPS according to the design approaches used to implement UPS Systems. According to the design approaches used to implement UPS Systems, as described by  Schneider Electric,the following are the main types of UPS:

• Standby
• Line Interactive
• Standby-Ferro
• Double Conversion On-line
• Delta Conversion On-line

Samsung Galaxy S II - A tough Competitor of iPhone?

sQuba - World's First Submarine Car,reality or fiction?

Three decades ago,in 1977,the James Bond impressed the world by driving a car that could 'fly' under water in the film titled "The Spy Who Loved Me".This role was then played by Roger Moore.This act of James Bond in that movie was merely an animation effect,not the reality.At that time it was not possible to drive any car under water,as there was no real submarine car at that time.But now submarine car is a reality.

This scene of James Bond's movie greatly inspired Frank M Rinderknecht,the founder and CEO of Swiss auto-maker company Rinspeed, to turn this idea into reality.He turned his dream into reality by developing world's first submarine car sQuba.sQuba is actually the world's first car that can be driven both on the road and under water.This car can actually 'fly' under water .Snapshots of this car are shown below:
