Clean Technology – Why it is the time to be Green?

What is the 'Need' of the, "Clean Technology"? Why Not? There is a desperate need to meet the challenges caused by climate change and environmental degradation. In the past, it was the entrepreneurial spirit that contributed most to the innovations with far-reaching benefits. Besides, scientists from outside the industry innovated technologies like steam power, the railways, telegraph, radios and telephone, petroleum, the automobile, computer, internet etc. Yet the role of entrepreneurial innovation in addressing environmental problems has received relatively little…

Radioactive Pollution

What is Radioactive Pollution? Radioactive Substances and nuclear radiations (i.e., alpha, beta & gamma-particles) produced during nuclear reactions, affect our environment adversely and thus radioactive pollution is created. Sources of Radioactive Pollution Low level radioactive liquid wastes, radioactive gaseous wastes & dusts are released during nuclear explosions. Effects of Radioactive Pollution I. The radioactive gaseous wastes are injected into the upper layer of atmosphere where, due to cooling they condense to fine-dust particles and thus Radioactive Cloud is formed. This…

Entropy and Disorder

In science, we look for patterns to discover nature's laws. What is the pattern common to all spontaneous changes? To find a pattern, it is often best to start with very simple examples, because then the pattern is likely to be more obvious. So let's think about two simple spontaneous changes -- the cooling of a hot metal and the expansion of a gas -- at a molecular level and search for their common feature. https://www.youtube.com/watch?v=ZsY4WcQOrfk A hot block of…
