February 24, 2005 10:41 IST All you need to charge your mobile is -- air! Students at the Department of Industrial Design at Indian Institute of Technology, Delhi have attached a turbine with a mobile phone that helps charge it even when the user is travelling, Head of the Department Professor Lalit Kumar Das told PTI. "The electricity generated by the turbine when moved by wind energy could charge a cellphone in an emergency. The specially designed turbine, which costs about Rs 200 to be developed inside a laboratory, is so small that it could be easily kept in a pocket, he said. The primary objective of the device is to extend mobile 'connectivity' where there is no electricity. The electricity could also be used for other purposes such as illumination and playing a radio. The device is best suited for coastal areas where the wind flows almost continuously.

Mobile Feelings Mobile Feelings The Mobile Feelings project, by Christa Sommerer and Laurent Mignonneau, studies how to communicate via virtual touch over mobile phone networks and explores the ambivalence of revealing personal information to anonymous listeners. They designed egg-shaped devices (picture) that integrate pulse sensor, scent/heat sensor (similar to those used to detect bad breath) and micro-ventilators capture the users's heartbeat, blood volume pressure and pulse, skin connectivity and transmit data over Bluetooth technology. The testers reported sensations of intimacy, bodily connection nearly embarrassing when they had to share the experience with total strangers. What is amusing is that they first decided to insert the technology into real pumpkins for an exhibition (picture above). After the show, the decomposing vegetables were substituted by less unconventional materials.
