IICM

IICM-Innovative Ideas & Creative Minds is a technological community of the Electronics & Communication dept of Pragati Engineering College initiated with a main view of providing a platform for the creative minds of Pragati. The forum was initiated by the pragatians-Divya Sri,Mounica Deepthi,Praveena,Anuradha. Officially launched by the dignitaries of Pragati on Jan10th 2008.

When a Plane flies on Wireless Power

An aeroplane consumes nearly 50% of its fuel during takeoff.25% of that fuel is used on the runway.Instead of using fuel,electric power could wirelessly propel an airplane.
Last year,there were two billion flights.by 2010,this figure will go up by 500million.A single trasalantic flight consumes 60,000 litres of fuel that release 140 tonnes of carbondioxide.Green house gases such as carbondioxide trap heat onto the earth and contribute to global warming.it’s a real problem.According to a recent UN report on climate change,the glaciers of gangotri that supply 70% of water to the ganga could melt by 2030.

If aeroplanes are part of the problem,nikola tesla,the extraordinary inventor of the AC motor who held over 1200 patents in his day,is a part of this solution.The principle of Resonance that underlies your ability to tune into a particular station is behind an exciting innovation in wireless power.In a recent issue of science,proff Marin soljacic and collegues at MIT demonstrate that over a distance of two metres they can wirelessly light up a 60-watt bulb.The transmitter coil emits a weak magnetic field that is only noticed by an identical coil tuned to it.As the coils resonate,energy is ‘tunnelled’from one to the other with high efficiency.
How can this slow global warming?an aeroplane consumes nearly 50% of its fuel during takeoff and 255 of that fuel is used on runway.Instead of using fuel,in theory,electric power could wirelessly propel an airplane to flight that would require significantly less fuel on board and shift our carbon burden to the lower atmosphere where it is less damaging.What could keep the plane up once airborne?Both light and microwaves can do long distance energy tranfer.in the 1980’s the canadiansbuilt an unmanned aircraft that could fly 20KM above a large microwave transmitter that powered it from the ground two years ago,NASA demonstrated that it could focus light(through a laser) and fly a model airplane that had photovoltaic cells,to convert the light into electricity.theses are the necessary technologies for tomorrow.Virgin atlantic is purchasing new boeing 787s that are made of lighter materials to consume 27% less fuel than comparable.
