As good as it getsThe State Transport (ST) bus may look like a relic of the past, but when it comes to keeping it clean, the methods used are almost futuristic. For the past year and a half, ST buses are being cleaned not by men, but by machines. A motorised `brush' moves alongside the length of the bus, sprinkling water and scrubbing it as it moves. And within 10 minutes, the bus looks like new. Almost.Says Sopan Nabde, depot manager, Shivajinagar Bus Depot, ``Installing this machine has resulted in huge savings. In the past, we had to have three men working round the clock and it cost us Rs. 21,000 per month. Besides, this system also saves on time and water.'' Old bus, new look, what more can one ask for?Exploring scienceScience can be fun - especially if it is lucidly and attractively presented.
