as i know many inventions are made in this century
in the fields like robotics, hybrid vehicular design and solar technology which are most interesting fields for me
in this i like the solar technology for new solar panel which has the high efficiency and coming to hybrid vehicular i give high rating to solar vehicles and brain controlled cars
in the field of robotics i give rank for the design of a robotic humming bird made in calfornia
i really like the concept of that robot actually it is not launched but i love it
