Tabacco: Nobody has gone into Space any further than orbiting a Satellite since 1972! Q. Why not? Answer: COST!
To reduce the Cost of Rocket Take-Off, Science has a novel Solution. Well, maybe not so novel! After all, almost all Office Buildings worth their salt have them. But what Genius/Nut concocted the concept of a 12-mile high Space Elevator that can lower to Earth and then elevate supplies 12-miles above ground to an orbiting satellite! The Satellite remains stationery over the planet because it orbits at the exact same velocity the planet rotates (12-miles up that is).
The Space Payload is then assembled 12-miles up, which – if nothing else – eliminates an awful lot of fuel required to effect an Earth Take-off! I’ll bet the folks at Otis Elevator never thought this day would come!
7,000,000 pounds of thrust will not be required to assemble Payloads in Space; but that’s what’s required to LAUNCH A SPACE ROCKET from Earth! Much of that fuel is required for Earth Launch to overcome the Weight of the Fuel itself! Add 100-pounds to the Payload (fuel or not) and you have to add how many pounds of extra fuel! And that added fuel is extra weight, which has to be accounted for with more fuel! How inefficient is that!
Maybe one of you Inventor-Readers is about to patent an Anti-Gravity Engine, which will render even that Space Elevator moot!
Company in Canada gets U.S. patent for space elevator
August 15, 2015 by Nancy Owano
Exploring space while seated on Earth, gazing up on screens in museum theaters or at home via VR headsets is exciting but the top imagination-grabber is the very idea of finding a way to access space. This is the present-day realm of creative thinking over space elevators, in the use of a giant tower to carry us to space.
Scientists working on space elevators are thinking about materials and designs that can be used to access space as an alternative to rocket technology. A sign of the times is the upcoming Space Elevator Conference 2015, which takes place this month in Seattle.
Imagine, said The Spaceward Foundation, the space elevator, serving as a track on which electric vehicles called “climbers” can travel up and down carrying about 10 tons of payload. “There are no intense gravity-loads during the trip, no acoustic vibration, no onboard fuel, nor any of the rest of the drama (and cost) associated with rocket launches”, it added.
Now a Canadian company, Thoth Technology in Ontario, has a patent for a space elevator to access space. It would reach 20km (12 miles) above the planet. Its engineers said the technology could save more than 30 percent of the fuel of a conventional rocket— spacecraft and people could be lifted to a level in the atmosphere requiring less force to launch.
As GCR (Global Construction Review) News described it, this is a freestanding space tower concept, held rigid by pressurized gas.
In Fast Company, Charlie Sorrel had some thoughts on this: ” The patent does say that the elevator could be scaled to reach 200km, but that’s a little like saying that your bank balance could be scaled to reach $1 billion—it’s technically true, but the execution may prove tricky.”(The patent said the tower could be further scaled to provide direct access to altitudes above 200 km and with the gravitation potential of Low Earth Orbit [LEO].)
The patent document reads: “The present invention is a self-supporting space elevator tower for the delivery of payloads to at least one platform or pod above the surface of the Earth for the purposes of space launch. The space elevator tower may also be used to deliver equipment, personnel and other objects or people to at least one platform or pod above the surface of the Earth for the purpose of scientific research, communications and tourism.”
Thoth’s approach suggests an interesting alternative. Eric Mack in CNET wrote, “Technically speaking, getting to space hasn’t become any easier over the past half century or so. It still requires using huge rockets to create a massive enough amount of force to push a payload beyond the grip of Earth’s gravity.” Or, as Information Week put it, “Rockets are extremely hard to launch off the face of the earth because of gravity and air resistance.”
In contrast, said Mack, the space elevator uses “much simpler gravity-defying technologies to access space.”
David Wagner of Information Week said Thoth is using “technology that, for the most part, we already have (to build the building at least). It uses modular tubes of Kevlar-polyethylene composites filled with helium. The tubes are much lighter and forgiving than modern building materials, and the helium helps hold the structure up.”
“From the top of the tower, space planes will launch in a single stage to orbit, returning to the top of the tower for refueling and reflight,” said Dr. Brendan Quine, the inventor and a professor at York University’s Lassonde School of Engineering.
Thoth Technology is a space and defense company in the business of services and products for space applications.

In the meantime,
While Nasa is busy testing its biggest ever rocket in the hope it will propel mankind to Mars, one company is planning a rather different approach to usher in a new era of space travel. http://www.dailymail.co.uk/sciencetech/article-3198474/Going-Space-elevator-tower-12-miles-high-one-day-astronauts-leg-cosmos.html
And you wonder how your Tax Dollar$ get wasted?
As well as tourism, the elevator could also be used for wind-energy generation and communications.
“Top of the Empire State Building for supreme view of Manhattan, anyone?”
The mastermind behind the project is inventor, Dr Brendan Quine.
‘Astronauts would ascent to 12 miles (20km) by electrical elevator.
‘From the top of the tower, space planes will launch in a single stage to orbit, returning to the top of the tower for refueling and reflight.’
While other designs for space elevators have involved complex designs using graphene or carbon nanotubes, the Thoth design reportedly uses inflatable sections and flywheels to provide dynamic stability.
This is not the first time a space elevator has been proposed, with many engineers considering it as a possibility since it was first suggested by Russian scientist Konstantin Tsiolkovsky in 1895.
Engineer, Peter Debney, last year proposed a theory that borrows the methods by which cathedrals control their centre of gravity – by tapering at the top – and applied it to the concept of an elevator that takes humans into space.
When building any tall structure – from gothic cathedrals to skyscrapers, and eventually a space elevator – the sturdiness and balance comes from its centre of gravity.
By creating strong, far-reaching foundations deep into the Earth, the centre of gravity is shifted from above the ground, to below it.
The second part of Mr Debney’s plan is to place a satellite in geostationary orbit, and lower a cable from it to the ground.
But as soon as the cable lowers, it changes the centre of gravity of the satellite, placing it at a lower orbit and causing it to move relative to the ground.
To keep the whole thing in orbit, a cable would then also need to be extended up at the same time, to keep the system balanced.
Because this would make a nonlinear system, the cable would need to extend out almost twice as far as it is brought down.
The alternative is to use a counterweight, such as a suitably sized asteroid, beyond geostationary orbit to balance the cable and save the excessive length.
The design by Thoth seeks to get around the complication of geostationary orbit by limiting its height to just 12 miles (20km) instead of the full 62 miles (100 km) considered the end of our atmosphere and the beginning of space.
Hurry up, folks, be the first to get your tickets for the thrill ride of a lifetime! Don’t forget to bring your iPhones for selfies so your friends and family can all die with envy! Or are you holding out for the ‘Extended Ride’ into the Cosmos? “Coney Island Cyclone, what Cyclone!”
