The speed with which technologies become obsolete is amazing! Electric Vehicles (EVs) are an example. The EV concept first began in the 1980s but ready availability of petroleum products made gasoline driven vehicles both faster and cheaper.

The 1970s saw a renewed interest in the field but the industry did not grow because research revealed that EV technology would be expensive. Fast depleting oil resources and increased environment pollution (smog, noise) in the twentieth century has forced world communities to think of alternate ways to meet the demand for better vehicles.

EV technology appears as a ray of hope in this direction. EVs are zero emission vehicles, noiseless except for the faint hum of the motor. They can be easily charged (at home or at work) saving the ordeal of long queues at gasoline stations. Capable of drawing electricity at night (when consumption is low) they ensure efficient use of power. With no gears or clutches, they are easy to maneuver and maintain.

Considering these advantages, developing countries including India are investing largely towards development of EVs which can travel longer distances and provide better comfort. The first EV (electric car) to be developed in India is the 'REVA'. it is a product of the REVA Electric Car Company - part of the Maini Group, in collaboration with Amerigon Inc. USA.

A preview of the car was organised at 'Smiles 2000', an exhibition on renewable energy, held in Bangalore recently. Specially designed for the Indian market, its first prototype was tested by the Automotive Research Association of India (ARAI) in 1996. Since then it has undergone extensive tests on Indian roads, the company spokesman said.

Being an EV, REVA is non-polluting. With no engine, exhaust, gears or clutches, it is ideal for 'stop-start' city driving. Compact size and small turning radius enable easy maneuvering and parking. The two computers on board help I better vehicle management. Side impact beams, a special steel frame, regenerative braking and body panels made of dent proof ABS ensure safety. Its on-board charger uses 220V power from a 15 Amp socket. REVA, a 2-door, 4-seater compact car, boasts of an 80km range on full charge with a top speed of 65km/hr.

Claimed to have acquired government approval for commercial production, REVA is slated for launch in early 2001 as a low priced car. When launched it is likely to revolutionise the concept of city mobility, sharing an equal concern for the environment.
