Talking about something similar, have you heard of the concept of Space elevator?
Arthur C. Clarke introduced it to the general public in "The Fountains of Paradise", although it is an idea from a Russian scientist...
What about Jack and the beanstalk, what kind of genetic engineering and mechanical engineering is required to have a plant grow as long as to reach the sky?
Not to metioned the speed and materials required to make it grow over night!
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
