Quotes about Space Elevator from the world's top natural health / natural living authors
"Via private space launches or via the (increasingly likely) space elevator, Earth's orbit could become as accessible as the deep ocean—not easy, not cheap, but still quite accessible to scientific research and even to the truly adventurous tourist.

White, a pioneer of space exploration, takes an "orbital stroll" outside of his spacecraft in zero gravity." - Alex Steffen, Worldchanging: A User's Guide for the 21st Century (Get the book.)
"It turns out, however, that a space elevator is not only plausible, it's potentially revolutionary.
Take a carbon nanoribbon—one a bit stronger than those we can make today, but not by much—and run it from a launch platform in the equatorial Pacific Ocean to a satellite about 62,000 miles (99,779 kilometers) up. The weight at the end keeps the ribbon taut, allowing a structure about the size of a dump truck to trundle up and down, carrying tons of satellites, construction materials, and even people."

"Third—and most ambitiously—we could recycle the junk and use it as the counterweight for an orbital sling (sometimes called a skyhook): an orbiting, spinning tether, sort of a cousin to the space elevator, designed to lift and fling satellites from low orbit into higher orbit without added propellant. If none of these cleanup proposals worked, we could start exploring the really weird ideas. AS
Life in the Shooting Gallery mihi Right now, we know of 1,100 large asteroids a kilometer wide or bigger with orbits that come near Earth."

Electromagnetic vehicles travel the length of the elevator to transfer passengers and cargo between Earth and space. High-strength cables work back and forth to provide adjustments to the position of the geosta-tion. An asteroid counterweight (not shown) maintains the center of mass at a geostationary point." - Douglas Mulhall, Our Molecular Future: How Nanotechnology, Robotics, Genetics and Artificial Intelligence Will Transform Our World (Get the book.)

nium. Contamination from antifouling paint, a deadly toxin for sea life, has been eliminated using surfaces that repel microorganisms by offering no rough areas for them to cling to, or by emitting an occasional electric charge. This reduces water drag, improves speed, and raises energy efficiency."
