Google X really did try to design a space elevator

A space elevator is just the thing that is needed to open up the high frontier of space.

A working space elevator is still not a reality as of yet. But some of the most intelligent and imaginative minds on Earth have been looking into the logistics of building such a space elevator. Rich DeVaul, head of Google X’s Rapid Evaluation team, has confirmed for the first time ever that Google’s super hush-hush R&D lab actually tried to design one.

“It would be a massive capital investment,” he said in this month’s issue of Fast Company. But once this hypothetical machine was built, “it could take you from ground to orbit with a net of basically zero energy. It drives down the space-access costs, operationally, to being incredibly low.”

Unfortunately, our current technological landscape has its limitations:

The team knew the cable would have to be exceptionally strong– “at least a hundred times stronger than the strongest steel that we have,” by ­[Google X researcher Dan Piponi]‘s calculations. He found one material that could do this: carbon nanotubes. But no one has manufactured a perfectly formed carbon nanotube strand longer than a meter. And so elevators “were put in a deep freeze,” as [Google X researcher Mitch Heinrich] says, and the team decided to keep tabs on any advances in the carbon nanotube field.

Google X’s space elevator ambitions might be frozen, but they’re not dead. Google’s just waiting for the material and manufacturing world to catch up with its sky-high ideas.
