A) 11.54 read the extracts (a-d). which are: introductions? conclusions? for years, i have been searching for the perfect energy solution. i have taken part in global research projects and worked with some of the best scientists and engineers in the field. now, i am pleased to tell you, i have finally found what i was looking for. b) gravity is truly universal and so these towers really are a global solution: they're clean, efficient, cheap and can be constructed almost any environment. c) do you think these towers are a viable solution for our future? i'd be interested to hear your thoughts after the q&a session. gustave eiffel, the french engineer who designed the eiffel tower, said that building a tall tower represented a "victory over the formidable law of gravity that tethers man to the ground". but today i'd like to offer you another perspective: what if we stopped fighting the power of gravity and harnessed it instead?
