This study assumes Space Elevators can and must be built. "Space Elevators: The Green Road to Space," completed in April 2021, emphasizes that Space Elevators will not replace rockets but would join them on parallel paths towards the stars. This Dual Space Access Strategy will carry out the missions that are now planned and ensure the future we dream of becomes a reality. Space Elevators are needed to do the "heavy lifting" for movement off planet. Their transformational characteristics will enable so many of humanity's dreams by moving huge mass to far away destinations.Space Elevator Vision: Space Elevators are the Green Road to Space while they enable humanity's most important missions by moving massive tonnage to GEO and beyond. They accomplish this safely, routinely, inexpensively, efficiently, daily and they are environmentally neutral.

This 18-month study has produced some remarkable results during a time of transition inside the space arena. As the dreams of many describe customer needs and lead to more assets in space (at GEO, the Moon and Mars), the realization grows that a robust permanent transportation infrastructure is desperately needed. Essentially, we (ISEC) must insert the "positive environmental impact" aspect of spaceflight into a new vision. Everyone needs to understand the potential benefits of liftoffs accomplished by electricity. Our new vision is:Space Elevators are the Green Road to Space - they enable humanity's most important missions by moving massive tonnage to GEO and beyond. They accomplish this safely, routinely, inexpensively, daily and they are environmentally neutral.This study shows how the Space Elevator can actually enhance the Earth's environment and accomplishes much to fulfill the dreams of many. The compatible and complementary combination of future rockets and Space Elevators leads to the implementation of the Dual Space Access Architecture which enables:Rockets to open up the Moon and Mars with Space Elevators to supply and grow the colonies. In addition, Space Elevators will enable Green Missions such as, Space Solar Power and L-1 Sun Shades.

A NEW Space Transportation Paradigm has emerged. Ideas brought forward in this report are presented in clear and understandable ways, although a revolutionary concept is becoming real. The envisioned cooperative and collaborative operations between rockets and space elevators will benefit mankind into the next century. 1- Space Elevators can be accomplished because there is a material for the tether, 2- Space Elevators are Earth Friendly, and 3- Space Elevators ENABLE Interplanetary Missions with:o Fast Transit to Mars (as short as 61 days, with variations out to 400+)o Can release towards Mars EVERY day (no 26 month wait)o Can move massive amounts of cargo (170,000 Metric tonnes/year to GEO and beyond)

SCUBA live aboard trip preparation. Step Zero process enables one to go on an adventure called an underwater photo safari with confidence. The appendix has a long checklist of things to bring and actions to complete. The book prepares one to go on a live aboard SCUBA adventure by assisting the answers to... Where do I want to go? How do I do it? Who shall I go with? How much do I pack? What do I need on the trip?What

The subject selected for this 2013 study is the Space Elevator Tether Climber. The objective of the one year study was to survey current concepts and technologies related to tether climbers, identify critical issues, questions, and concerns, assess their impact on the development of space elevators, and project towards the future. The following are a few of the conclusions:¿ The study used the concept of "constant power" as a baseline because of its ability to lower design requirements on the tether climber. ¿ The mass breakout of 6 MT for a climber and 14 MT for customer payloads seems feasible. The estimate is that with a travel time of one week to GEO seven tether climbers can be on a tether simultaneously. ¿ The communication architecture should be integrated into the space elevator infrastructure and nodal layout. ¿ Solar power, as the sole source, appears achievable.¿ The use of laser power as the sole source also seems achievable.
