The Potential of Building a Space Elevator for Cost-Effective Space Travel
TLDR The podcast episode explores the concept of a space elevator as a more affordable way to reach space, with carbon nanotubes being the main obstacle. The episode also discusses the potential uses of a space elevator and the challenges of avoiding space debris.
Timestamped Summary
00:00
The podcast episode titled "Can we build an elevator to space?" from "Stuff You Should Know" begins with an ad for AC Hotels by Marriott and the Capital One Quicksilver card.
03:47
The podcast episode titled "Can we build an elevator to space?" from "Stuff You Should Know" discusses the end of the space shuttle program and the potential for a space elevator as a more cost-effective way to get to space.
07:28
A space elevator is a feasible concept except for the need for carbon nanotubes that are currently not long enough.
11:16
Carbon nanotubes are incredibly strong and flexible, but scientists still don't fully understand them and are working on making them longer and more durable for use in a space elevator.
15:04
The space ribbon for the space elevator would be braided together like a rope, either with several meters in length or shorter strands, and it needs to be thick enough for lifters to gain traction on it.
18:48
The space elevator could be used to shuttle supplies to the International Space Station or transport materials from an asteroid mining operation, and it would cost significantly less than current methods of delivering items to outer space. However, a major challenge is avoiding space debris, which could potentially damage or destroy the space elevator.
22:41
Liftport, a private firm that has partnered with NASA, is currently working on a lunar version of the space elevator, which could be completed within the decade and would be significantly cheaper than current methods of space travel.
26:15
Private space exploration is the future and will likely be funded by billionaires like Jeff Bezos and Elon Musk rather than NASA.
