Space Elevators

When I first heard of space elevators, I thought the idea was a little far-fetched. It didn’t seem practical, possible, or useful. However, after researching the concept further today, I am very interested in the development of the idea.

According to NASA, the idea of an elevator to space was first proposed in 1895. It can transport people and cargo to beyond our atmosphere more efficiently than a rocket. With a rocket ship, transporting cargo costs about $10,000 per pound. However, with a space elevator, it would only cost $100-$400 per pound. I found a brief video that explains the concept and mechanics of the space elevator with more clarity than I could, so I’ve included that for convenience (complete with tacky "space" music):


After learning about the basic concept, it still seemed more like science fiction than reality. I was curious as to what recent news there was regarding this concept. I found that in 2012, a company called LiftPort started a Kickstarter campaign to raise $8,000 for their space elevator research. They ended up raising over $110,000. I’ve included their campaign video, which even talks about building a space elevator on the moon!

Another more recent development happened just this summer, when a Canadian company patented an inflatable space elevator idea. This elevator could reach 12 miles high and would be 30 percent cheaper to operate than the cost of fueling a rocket to the same height. This video from CNBC briefly touches on the story, while simultaneously showing the general confusion that most people have about the concept.


The funniest part of that news report comes at the end of the segment, when one news anchor comments “I don’t know how you get a toilet to work at that height”. After some brief research online, I’ve learned that the elevation of the plumbing does not particularly effect its function. Glad we’ve got that mystery resolved.
