Description:

Describing a passively stabilized

version of a Kinetic-Energy Supported

Transportation Structure.

Uses a constant load distributed

along the entire endless-loop

between Earth-surface and

geosynchronous earth orbit.

---------------------------------

PASSIVELY STABILIZED KESTS

Specific Insight of this conceptual synthesis: This

configuration achieves stability during movement of payloads

by maintaining a constant mass load distributed throughout

the entire length of the KESTS (Kinetic-Energy Supported

Transportation Structure) ellipse connecting Earth Surface

with Geosynchronous Earth Orbit.

Design: This KESTS has a slowly moving endless-loop

"train" extending all the way around its orbital path.

Whenever payload gets on the train, it does so in the form

of a boxcar of fixed mass, cg, and outer dimensions, and

displaces an equivalent mass boxcar at the point of transfer

to/from the KESTS "train".

Other effects of this concept: The KESTS moving

orbital mass stream moves at a velocity significantly higher

than that which would put it in its elliptical orbit, due

to the force toward the center of the Earth distributed

everywhere along the KESTS. The effect of the distributed

load is to make the KESTS behave as if it were in a higher

gravitational field area.

Train movement: The train moves at a constant speed

everywhere around the KESTS. Its speed needs to be fast

enough to provide acceptable transit times between Earth

and GEO, as well as slow enough to have practical

accellerations prior to insertion onto the train. Perhaps

the energy of the displaced boxcar, being decellerated to

the velocity of the station, could be coupled to accellerate

the payload, note. Analogy is that of a car accellerating

onto a freeway ramp, up to speed for insertion into the

freeway traffic. If 70 mph were used for the "train" speed,

allowing contemporary automotive technology to be used for

the accellerator for the boxcars, the trip one-way would

take:

((22300 miles)*(1.5 half ellipse approx)/70mph)/(24hrs per

day) = 20 days ; longer than solar flare predict time

To make the trip in one day, 24 hours, the train speed would

therefore need to be 20 times 70 mph, or = 1400mph.

1400 mph is supersonic; probably would lose too much energy

to be efficient.

1400 mph or higher might be feasable using a second vacuum

tube skin, supported by the KESTS. Railgun technology could

be used to accellerate payload boxcars to such speeds and

human-tolerable accellerations, although the terminal

becomes complex. Perhaps a 70 mph version for economy

class, radiation-insensitive payloads, and the second train

running at 1400 mph or faster also on the same KESTS.
