Air tanks to prevent road accidents
Pranav Singh
Class IX
Maharaja Agrasen Vidyalaya, Memnagar Ahmedabad
Accidents are common today, especially on the crowded roads of metropolises. To escape this situation, Pranav suggests that small air filled tanks be fixed under the base of car. The air inside them can be compressed to such an extent that a large volume of gas can be stored in it. In case of a collision, the stored gas will be released, and the car will be heaved upwards due to the force to save it from the accident.
(If it sounds strange then suggest some thing better. Ed).
Seeds to generate electricity
Seeds exert a lot of pressure while germinating. If kept inside a container along with some water for a few weeks, they can generate force that can break a thin glass container. If thousands and thousands of seeds are left to germinate in a large glass container, it will exert a huge amount of pressure on the walls of the container eventually leading to its breakage. The mechanical energy generated in the process can then be converted into electrical energy. The seeds can later be then given to farmers and water can be used for various purposes so that nothing goes waste.
(In earlier times, gram seeds were placed in the crevices in the rocks to break them apart, using the same principle. Ed)
Road bumps to light houses
There are many bumps or speed breakers on the roads. We can design speed breakers that would get pressed under a vehicle's pressure. The mechanical energy thus generated can be converted into electrical energy and supplied to homes.
(Similar ideas were received by National Innovation Foundation nif.org.in, several years ago from many people. Shri Sham Rao Parhate, in fact made a prototype using hydraulic system to amplify the pressure created by moving vehicles. Why do not we still have working models of such creative ideas ? Ask the makers of public roads and culverts in your region. Ed)
Insect repellent floors
Shalini Pal,Class IX
Maharaja Agrasen Vidyalaya, Memnagar Ahmedabad
A permanent layer of bacteria and insect resistant material should be placed on the floors in houses so that we do not have to clean the floors everyday with repellents. Such floors will also be preferred by mothers because kids often end up carrying infection playing on the floors.
(A paint mixed with nano particles of Titanium dioxide or silver can in fact achieve just this effect, but Shalini did not know about nano particles so far. Will teachers teach such ideas to our children now? Ed) |
