Japanese construction firm, Obayashi, plans to build a soaring 96,000 meter elevator capable of transporting people and cargo into space at a fraction of the cost- and with only a fraction of the harmful emissions!- of current rocket flights. Really.

Representatives from Obayashi claim that this science fiction-y idea is a possibility now, thanks to advances in solar efficiency and- more importantly- the development of the carbon nano-materials that make up the space elevator’s cables. “The tensile strength is almost a hundred times stronger than steel cable so it’s possible,” Mr Yoji Ishikawa, a research and development manager at Obayashi, said in a statement. “Right now we can’t make the cable long enough. We can only make 3 cm long nanotubes but we need much more … We think by 2030 we’ll be able to do it.”

As for whether or not such a plan is feasible, Obayashi’s materials point out that the space shuttle spent about $22,000 per kilogram to take cargo into space. For the space elevator, the estimated cost would be somewhere around $200. Once it’s been built, of course.

If it happens, Obayashi’s space elevator would dwarf buildings like the new World Trade Center and Dubai’s Burj Khalifa- and, of course, neither of those things can help you get into low Earth orbit for $200/kg.
