Our theoretical description of space is the entire observable universe which extends to 13.8 Billion Lightyears (because the universe is 13.8 Billion Years old) through whichever direction we look at it (and is the same from any point of observation in the universe, since the universe is infinite). But, how much have we explored? The furthest distance reached by a machine, the voyager I, is the outskirts of our solar which is a few light hours from earth which it took 35 years to sail in empty space going at an astonishing speed of 1100 Km/sec. Humans, on the other hand have not gone further than the moon (360,000 km away from earth) and are soon planning a trip to mars.
Whenever we hear the word “Tornado” we think of destruction and catastrophe. But, to one man it meant, “How can I generate power with that?” It makes sense. Most large scale power generation methods, directly or indirectly involve rotating parts and tornadoes possess a huge amount of rotational kinetic energy. So if we could create a tornado and harness its kinetic energy, it would effectively provide us with a clean source of energy (provided that it is controlled). Generally tornadoes are caused by the presence of a large temperature gradient present in the atmosphere.
The economic success of a nation depends prominently on its evolution in communication and transportation. Communication is steadily growing its speed, while the same cannot be matched by transportation. There are currently 5 modes of transportation; road, rail, air and sea. Out of these road and sea are quite slow, air is fast but expensive and rail is not as fast as it needs to be. Therefore there is a need to bridge the technological as well as an economical gap between a cheap mode of transportation (say, land) and a fast mode of transportation (like air).
