A Space Elevator For the Moon?

The idea of a space elevator has been around since the late 1800's, but despite big dreams and years of research, the low-cost, easy access to orbit that a space elevator promises is likely still decades away. The biggest problem rests on the fact that no one has been able to successfully manufacture long ribbons made of ultra-light, ultra-strong carbon nanotubes, the only known material that is strong enough for a space elevator. But entrepreneur Michael Laine believes a lunar elevator – a space elevator from the surface of the Moon – could be created with materials that are available now. With more research and the right amount of capital, Laine says a lunar elevator could be built within a decade.

While Laine said he is still "emotionally very invested" in the concept of a space elevator based on Earth, for now he has shifted his focus to the lunar elevator. "There was a question of where was I going to put my time," he told Universe Today, "and being able to do this soon – perhaps within 5-7 years and not some mythic 15-25 years in the future is enticing."…
