Supercapacitors might help to replace use of petrol one day: Prof Apparao M. Rao: Expert.

Hyderabad, December 19, 2017..... Imagine charging your mobile phone in just a few seconds or electric car in only a few minutes. Electric buses which were once a science fiction are now a reality. These and many exciting subjects came up for discussion at the ongoing International Conference on Advanced Functional Materials 2017 here at the Rajiv Gandhi University of Knowledge Technology(RGUKT), Basar in Adilabad district.Supercapacitors might help to replace the use of petrol one day. Ground-breaking research has resulted in the development of technology that could revolutionize the capabilities which until recently was not possible. The best researchers in the world are working on it. China has already made progress in this area, shared Indian born American Professor Apparao M. Rao, Nano Material Expert, Director, Clemson Nanomaterials Institute, 128years old Clemson University of America while delivering Key Note address at RGUKT.

While delivering his keynote address on “Energy andour future” to 200 plus delegates from across the globe, Prof. Apparao M. Rao,whose research in Nanoscience and Nanotechnology has been cited over 30,000 inthe open literature. He shared the story of energy technology at ClemsonNanomaterials Institute. He talked mainly energy generation/production and itsstorage.  He shared oil consumption projections for 2030 and saidthat only Japan would be able to manage well its oil consumption without muchgrowth in it compared to other countries.  And there is a search foralternate energy sources, he told.  Prof Rao, a Telugu man who servedas Chairman of several international conferences, spoke about Triboelectricityand how it can be stored and used later.


Triboelectricity is a charge of electricity generatedby friction. 


Speaking further, Prof Rao added that theTriboelectric Nanogenerators could power cell phone / small devices with thegenerator placed in shoe soles. The same technology can be incorporated intofloor tiles to generate electricity.  This is a new technology whichis about 3-4 years old and cheaper than other alternative sources like wind orsolar. The same technique can also be built-in textiles. He gave an example ofLED jackets that light up without any external power source/battery and can beused on people working in night time on highways, etc.


China wants to implement Triboelectric Nanogeneratorsto power street lights, etc.. And wants to harness and generate energy where alot of people walk. He also spoke about Supercapacitors which might help to replacethe use of petrol one day. China is experimenting with a new form of electricbus, known as Capabus. Capabus is a capacitor vehicle or capavehicle.  Supercapacitors are then charged on each bus stop with apantograph (like a tram). 30 seconds are enough to charge the bus to 50%, andit takes 80 seconds to charge to 100%.


It runs without continuous overhead lines (is anautonomous vehicle) by using power stored in large onboard electricdouble-layer capacitors (EDLCs), which are quickly recharged whenever thevehicle stops at any bus stop. Electric buses are gaining prominence in various partsof the world. China initially experimented and now commercially deployed themall over China.  China is known for stringent emission standards, andhence, Capabuses found increased acceptance, he added. Prof Rao also talkedabout similar buses in Germany and Singapore.


Replying to a query from the audience on practicalapplications and its usage in present day he said that China is generatingTriboelectricity in fishing nets. China is the leader in this followed byKorea, he said. The commercial application of this technology can happen in thenext three years, he opined.
