Full-Rotation Electric Vehicle Pivo 2, an electrical car introduced by Nissan, can swivel 360 degrees to face in any direction. So now there is never any need to back the car up: simply swivel the cab 180 degrees and drive what is now forward. The wheels can all turn 90 degrees. So now one can drive sideways while facing diagonally… if one really wants to.
Largest Turbine This is one of the world’s largest turbine and was built at Siemens’ Power Generation plant in Berlin. It measures 13 m in length, 5 m in height, and weighs 444 tonnes. It generates an output of 340 MW and aims to achieve an efficiency of around 60%.
Laser Tag painting The 90-meter-high piece of graffiti scrawled on the back of this office building in Rotterdam, Netherlands, was the product not of hundreds of aerosol cans but of Laser Tag, an open-source painting program. As an ordinary green laser pointer’s beam was drawn across the building, a sensitive low-noise camera captured its movements and relayed them to a laptop running the software. Then a movie projector ”painted” the squiggles onto the multi-storey canvas in real time.
Earth racer Earthrace is a 78-foot (24 m), wave-piercing trimaran, originally created as part of a project to break the world record for circumnavigating the globe in a powerboat. Its time of 61 days broke several records, however failed to supercede the fastest record by Groupama 3 of 49 days. The vessel uses biodiesel fuel as power supply. It also uses other eco-friendly materials, such as vegetable oil lubricants, hemp composites.
3D Skull Modeling Designers use databases of North American and European body measurements to create their products but lack data to adapt the designs to Asians. Roger Ball, an industrial designer at Hong Kong Polytechnic University, has digitally scanned the heads of 2000 people from six regions of China and created computer models of average Chinese heads He intends to sell the models to companies that make helmets, eyeglasses, and face masks for Asians
Smallest Instrumentation Amplifier The AD8235 is the smallest and lowest power instrumentation amplifier in the industry. It measures 1.6 mm x 2.0 mm—one- third the size of competing instrumentation amplifiers. The AD8235 draws a maximum quiescent current of 40 μA. In addition, it draws a maximum 500 nA of current during shutdown mode, making it an excellent instrumentation amplifier for battery powered, portable applications. It can operate on supply voltages as low as 1.8 V.
Electrical Engineering Department of IIT Kharagpur
The Department of Electrical Engineering,one of the first three engineering departments in IIT Kharagpur, started in 1951.
In the research field, so far number of degrees awarded are 140 in PhD and 44 in MS (by research) EE produced the first MS scholar of the Institute in 1992.
In 1955M. Tech. in ElectricalMachineswas started
in 1963 the M. Tech.in ‘Power Systems’ wasstarted byDr S. P. Roychoudhury.
In 1959 M. Tech. inControl SystemEngineeringwas introduced.
First B Tech pass out batch was in 1964 with 50 students
Dr. P. K. Rajagopalan becoming the first Doctorate of the department in 1960
Present Head of the department of Electrical EngineeringDepartment is Prof. Jayanta Pal.
