The Physics Department of DAV College, Jalandhar organised an invited talk on the topic “Space Elevator: A next Frontier ” and a poster making competition on the theme Futuristic Technologies, on Feb. 27, 2023 to commemorate the National Science Day. The resource person for the event was Dr. R. K. Seth, Associate Professor, DAV University, Jalandhar. The session started with recitation of DAV anthem. Dr. Ritu Pal (Incharge Physics Association) welcomed the resourced person, Principal Dr. Rajesh Kumar, HoD Physics Department Dr. Kunwar Rajeev, all the faculty members and the students. Prof. Kunwar Rajeev and Principal sir accorded a floral welcome to the resource person. Afterwards, Dr. Ritu Pal introduced the speaker to the audience.
Dr. R. K. Seth started his talk with elaboration of an elevator. He has worked on the subject ‘Space Elevator’ as a future generation technology. It is an alternative technology to access space. He said that NASA has proposed a 36000 km long vertical road using Carbon nanotube. Carbon nanotube is the prime material to build such elevators. He also explained that equators could be the best place on earth for space elevators. Dr. Seth provided detailed information about the vision of this technology. If we sustain the height of space tower upto 20 km, then launching of satellite becomes very easy by saving 30% of the energy. It also reduces space junk and induces possibility of harvesting high altitude renewable energy resource, thereby provides increased efficiency, enhanced communication and space tourism. The estimated cost for the futuristic project is $7 Billion i.e. 60000 crores. He also motivated the students to indulge in space and engineering. This work has been acknowledged by NASA, CTB, CNN and various renowned magazines. The entire talk was quite interactive and the students enjoyed it a lot.
The students from UG and PG classes enthusiastically participated in the poster presentation competition. Dr. Seth was judge for the event. In the end, a valedictory session was organised. Parneet Kaur from M.Sc. II (Physics) achieved the first prize and Sumit from M.Sc. I (Physics) got the second prize for best poster presentation. Two more students were given consolation prizes for their sincere efforts. Along with this the winners of another event named “paragraph writing competition” organized on World radio day were also honored.
The session ended up by a formal vote of thanks proposed by Dr. Satish Kumar.
