Electrical seminar topic

i am a final year Electrical engg,
i am supposed to give a 50 mark seminar on any topic related to "recent trends on electrical and electronics" preferably IEEE papers

close to 150 topics are done by all my seniors.
my present batch is doing seminars on rail gun,smart grids,holograms,sputtering etc.

i have also gone through the seminars topics list but cannot decide on any.


Thanks
