 Often I have come across reports in the media, that some websites project the boundaries of our country, INDIA, in an incorrect manner. The Government comes out in the open and rejects such claims. We, Indians, can assert our boundaries in a much stronger way. It is by getting the outline map of India printed in all the currency notes of our country. In India's currency notes, the white space,where-in the water- marking feature is visible, can be chosen for printing the outline map of I...

IN EVERY BIT OF WASTE, THERE IS GOLD.........WASTE WATER IN RESIDENTIAL BUILDINGS - BATH WATER, WASH BASIN WATER ETC.. THE WASTE WATER COMING DOWN THE LONG PIPE IN ALL RESIDENTIAL BUILDINGS HAS INCREDIBLE ENERGY ASSOCIATED WITH IT AND THAT CAN BE TAPPED.  WE CAN CERTAINLY GENERATE RENEWABLE ENERGY FROM THE WATER FLOWING DOWN THE PIPE. THE ENERGY OF THE FLOWING WATER CAN BE USED TO RUN A TURBINE OR ANY OTHER EQUIVALENT MECHANISM ( USING SOMETHING SIMILAR TO AN ANEMOMETER FO...

All of us know all rivers have lots of capablity to produce elecricity but we have to use very costly hydro plants which harms the aquatic life and displaces many people from their homes but my new idea is to use the speed of the river using floating styrafoam generators with a turbine the generator if i am succesful they will be like fixed buoys attached to the shore and will produce 3 KW/hr for rivers like ganges and missipi per unit we can have many units like this and that produces power ...

 We talk about harnessing solar energy but economical factors pull us down all the time. The world is highly asymmetric. Almost 38 years ago, there was a proposal to bring solar energy from outer space using the microwave transmission mechanism. This process requires tons of solar arrays to be stationed in outer space. How difficult that would be.It is possible to do that on earth. Thanks to the climatic asymmetry God has bestowed on our beautiful planet. The hot regions could serve as s...

 It was just an imagination. We know that fishes swim through water at the greatest speed. The ease with which they achieve such high levels of speed is attributed to its body structure. If it were possible to implement its body structure in the form of attachable curved air bags (filled at some pressure) on the left and right side of the truck and also providing an attachable protrusion (an air bag) like that of a fish with a crescent shaped tail then it would be possible to cut down th...

 If there is a way to harness solar energy in the context of ships that roam around the oceans, surely, it may lead to reduction in emission. Not only that, plenty of fuel can be saved.Please correct me if I am wrong.Regards, Prakash Vaithyanathanpvaithyanathan@gmail.com

 Nowadays schools have made it an habit of providing snacks atleast twice a day. In most of the schools these snacks are provided in steel plates which must be necessarily washed before the next use. We spend water here. If the school children can make use of one of the coconut shells from their "homes not from anywhere else" for their snacks we may surely reduce the consumption of water in a school context. Hygiene is indeed an issue but our homes are indeed hygienic. Whether ...

All of us fear to drive our veichle either car,bike in sharp turnings and in most accidents it is always "The accident occurred after the vehicle's driver lost control while negotiating a sharp turn," It is very tough as the driver does not know what comes in that way and if he is not aware I have a good low cost solution for this we place plane mirrors in the sharp turn at 45*  and the the passenger from both sides can see each other and avoid the accident
