My Robot Robbi
Have you ever seen a robot? No? Meet my robot friend and philosopher, Robbi. To be precise, its name is Robbi-999XHA. You may wonder what is Robbi-999XHA. Just as cars, washing machines or xerox machines are of different models with different names, does this strange name also indicate something similar? Yes, you’re absolutely right! It is a particular domestic model of a robot. 999 stands for the year of its make — 1999, X stands for deluxe model, and HA is for home appliance....
What is Daylight Saving Time?
People in some parts of the world gain an extra hour in winters and are able to sleep and snore that much longer thanks to a suggestion by Benjamin Franklin about daylight saving time. But when the suggestion was first made, it raised such a furore not only from those kept awake by the extra snoring but also from others and they wasted a lot of time fighting over this extra hour. Actually the confusion began when the postal service and the railways began to connect far-flung cities....
What is Geothermal Energy?
In winter, all of us warm water in the geysers in the bathroom for bathing. Nature too has geysers which throw up a huge amount of hot water and steam.

Creating Light from Garbage
July 22: We all create garbage. Every day we throw away armloads of things that we don’t need. Wrappers, leftovers, car parts, torn cloth, vegetable remains and mounds of other such stuff. What we throw away at home is domestic garbage. There’s much more that factories throw away. Garbage from factories is often very dangerous, because it could be poisonous chemicals, or plastics that choke the earth. The result of all this throwing away is that garbage levels around the world are rising, and fast....
Protest Without Clothes
July 1: See this picture. What do you think the children were doing? No, they were not waiting for a community bath. They were at a gram sabha (village meeting).

Roy of Light
November 4: While cities and towns have the privilege of an electricity connection, there are still a number of remote villages in India that lack this facility. Their homes remain shockingly dark, even on the threshold of the twenty-first century. It’s a reality that the Indian government has done little to change. Providing electricity to all of India appears to be beyond its reach, even today. So the loudest cheers must be reserved for the man who says, yes, it’s possible to light up all the villages in India, even the poorest, most remote ones....
