AN ELEVATOR TO GOD (ok, to space because we don't actually know where heaven is located) IN OUR LIFETIME! (Not yours though baby boomers)

Blogger note: This original post was published almost 5 years ago... but amazingly, it is now a doable thing to cheaply deliver people, supplies to the International Space Station AND BEYOND! Read this post because it is accurate and good... but then read the addenda at the end which adds a few more truly amazing facts, though some information on Elon Musk has changed to date.
 

SciFi author Arthur C. Clakre wrote about it in his 1979 novel The Fountains of Paradise and it WAS science fiction then... but not any more. There are scientists who think it can be done--and it could be a reality in this century, possibly as early as 2050.

Now that's pretty impressive!

Spoiler alert: much of the technical language is not understood by mere mortals. It is included to impress you so you think I do.)

"It's a phenomenal enabling technology that would open up our Solar System to humankind," says Peter Swan, President of the International Space Elevator Consortium. "I think the first ones will be robotic, and then 10-15 years after that, we'll have six to eight elevators that are safe enough to carry people."

The concept is simple. First, you would need a landing station that, let's say, would be the equivalent of floor 12,000,003 (avoiding the 13th floor, of course). That landing station, maybe called God's Little Acre, would be a satellite or space-debris platform in geosynchronous orbit with the earth--a floating anchor, so to speak--and there are lots of possibilities out there.

Earth station would best be about 600 miles west of the Galapagos Islands because of the rarity of hurricanes, tornadoes and typhoons in that area, say those smarter than me.

Then you need a very strong cable--which doesn't yet exist--running between the two. There are now several concepts that would produce a cable with sufficient strength. One is a diamond-like nanothread material. Another is a cable made of carbon nanotubes with a tensile strength of 63 gigapascal--about 13 times stronger than the toughest steel. And that cable would need to be about 60,000 miles long. (Remember, up AND back with a counterweight and/or maglev technology similarly as used on high-speed trains.)

Oh, and we'd have to dig up an extra $100 BILLION or so.

Now here's the kicker... IT IS POSSIBLE, say many involved with the knowledge and desire to do it. But how does one go from concept to reality?

The reason we would do this? It would be incredibly less costly to send stuff to space... and from this platform, the universe would open to us as never before. 

Elon Musk, one of the most fascinating people of today, has offered his say. He is the genius behind SpaceX which develops and launches space vehicles, CEO and chief product architect of Tesla Motors. He is also the founder of SpaceX and a co-founder of PayPal and Tesla Motors. He has also envisioned a conceptual high-speed transportation system known as the Hyperloop.

With Hyperloop, Musk envisions 'shooting' people from Los Angeles to San Francisco in a metal tube in just 35 minutes. How's that for a starter? But regarding the space elevator, he says it would be easier to "have a bridge from LA to Tokyo." So what does he know?

Interestingly, as bizarre as this seems, remember that the Wright brothers' first flight was in 1903. Who then would have visualized humans would land on the moon just 66 years later--less than a lifetime!

As Groucho Marx said, "Time flies like an arrow, fruit flies like a banana."

Special updated info... this is not only doable but in the planning stage!

Lead from the Wall Street Journal, Sept., 2018

"Gradually you accelerate upward, reaching a cruising speed of several hundred miles per hour. Your elevator car moves up a cable 100 million times as long as it is wide--connected on one end to a platform in the ocean (Ed. comment--See, I told you so) and, on the other end, to a counterweight, a heavy mass orbiting high above the planet--kept taut by centrifugal forces. It takes about two weeks to reach the top of the cabl, some 60,000 miles above the Earth's surface. But the trip is serene, with none of the G-force of a rocket ride."

The elevators would be able to carry people and supplies to space without the need for a space shuttle and the special skills required of its occupants to fly it... and at much less cost! But really, can we do it?

Yep, it is technically possible... and as we do more, we learn more and have the advantage of all the discoveries to follow by the target year, 2050. A Japanese firm is already working on it and says do-ability by 2035 is target.

Well, then all we need is that little bit of competition to do it first. A NASA-backd company won the battle to try.

In a word, WOW!

I felt the earth move once!







Actually, I have had two very notable visits to The Willis Tower--formerly The Sears Tower--2nd tallest building in the western hemisphere. It rises 108 stories, 1,452-feet (1730 counting antennas) above Chicago's downtown. Its ultimate height was determined by what the FAA would allow so it would not affect planes landing at Ohare and Midway airports.

But first, as they say on television, some interesting background.

One World Trade Center--built in 2006 as a tribute to the two World Trade Center buildings--including antennas is 46 feet taller at 1776 to honor the date of the signing of the Declaration of Independence.

Completed more than 40 years ago, The Willis Tower is an ancient, not particularly beautiful building by comparison to today's giants. But it was for a number of years, the tallest building in the world. That was before technology and bragging rights made the race for the sky a worthy pursuit. Today it occupies last place in the tallest top 10 list.

Notably though, the race for the tallest is still to the future. Architect Frank Lloyd Wright who died in 1957 proposed to build a mile-high building rising 548 stories to house exclusive residences for more than 100,000 residents. He had the plans ready for presentation to Chicago movers and shakers but the practicality and the cost put the project on permanent hold just one year before he died. He did however show that a structure that high was possible.

Today the focus in New York where skyscrapers abound has turned to very tall and slender exclusive residence buildings using new technology with different types of unique problems to solve. More of that next post. Hint: If you are liking that thought of that killer view of Central Park but aren't yet in the multi-multi-million (or billion) dollar bracket, some nice little bungalow almost anywhere might be a better option. More about that tomorrow.

Now, about me... it's all about me:
View from the Willis Tower 103 floors above Chicago
Experience No. 1: The Willis Tower is actually built four feet shorter on one side and designed to sway as much as 6 feet in hefty winds. (It ain't called the Windy City for nothing.) I was on the 100th floor in the offices of a large attorney firm surrounded by at least a dozen 'dot every i, cross every t' legals as we were closing on the purchase of a group of magazines. (That was my business.)                                                                                                                                                       
The winds were howling. We could all feel the building sway as if we were in a boat on the sea. Six feet at 1/4th mile high made me appreciate how those ultra high divers must feel as they climb that skinny ladder to the top. It was no small thing to the senses to imagine us about to topple to our deaths. We were not much comforted to be told 'That's why we don't fill the coffee cups and water glasses too full (ha ha ha.)"

Personally, I believe the whole thing was a bargaining ploy to get us to act irrationally just to get the heck out of there.

Experience No. 2: Perhaps the weirdest phenomena I have ever experienced is when I took my family to the Tower's 103rd floor SkyDeck on a later trip. The crowded elevator ride to the top and down is without an attendant. It took just over a minute in the large express elevator, gulping to clear our ears as we rose. Our progress was marked by a silhouette of the building on a monitor. Rising, the image filled, as if one was pouring milk into it, until we were at the top. Going down, the image emptied.

But a strange thing happened on our descent. All 40 of us in the giant cage watched progress of our trip to ground level. But about half way down, the image showed us stopping and then beginning to rise to the top again. Now we all knew that the elevator NEVER stopped or even slowed. It was a straight shot down. Yet, the image told our senses differently. When we finally stopped and the doors opened, we all felt sure we were at the top again... but we weren't. There was a big laugh and sigh of relief as we all realized we were unintentionally duped.

Proof again that mind over matter is a fact.

Tomorrow: The longest commutes by elevator.

    Part I, The Set Up: Classic joke ALL WRONG! Part II will blow your mind, I promise.


    The elevator operator





    Back story: In the olden days elevators were not 'do-it-yourself' transporters.* They required an elevator operator to make them go, usually someone pleasant who makes friends easily.

    So, his passenger greets the operator and asks:

    "How is your day going?"

    "Oh, it has its ups and downs."

    (Laugh track crescendos... then fades)

    Now this was not an easy job... well, sort of it was. In the early days, it required training before earning an elevator operator license.

    Elevator control panel
    If you think modern elevators were a step into a bold new future (and they were), when some people saw their first escalator, they didn't know what to do and others couldn't figure how to safely step on and off. Many just stood and marveled at where all those steps that disappeared into the floor were going and where the new ones were coming from.

    A few worried about being transported into an alternative universe (like I was... but that's another story). Some stores stationed an employee (escalator operator?) at the bottom offering instructions or a helping hand. Really.

    But the old "ups and downs" joke won't work any more because German elevator manufacturer Thyssen-Krupp has something up its sleeve for the skyscraping record breaking heights of today's world. They are testing 'The Sideways Elevator."

    In its test tower the company is replacing steel ropes with magnetic levitation used on high-speed trains. Without the need to stabilize a central cable, these elevators require half the building's prior elevator footprint and multiple cars can use a single looping shaft, vertically AND horizontally, at up to 11 miles-per-hour. Riders can be at their desired stop, dizzy or not, within 30 seconds.

    Mile High
    Powerful magnets suspend and propel the cars from floor to floor to any created stop point. Building operations can add or remove cars depending on demand and occupancy. Says the concept's director for vertical transportation, "The mile-high building is easily achievable. There is absolutely no limit to how far you can go."

    There actually was one planned and on the drawing board, four times taller than today's giants. Frank Lloyd Wright talked about its fesibility in his 1956 book, A Testament. The design, intended to be built in Chicago, would have included 528 stories, with a gross area of 18,460,000 square feet. Wright stated that there would be parking for 15,000 cars and 150 helicopters. There's a lot here for King Kong to like.

    So I thought this would be the ultimate in elevators. Boy, was I wrong! When you read Elevators, Part II, THE NEXT THING will blow your mind. I promise! Stay tuned.  

         * Historically, simple elevators really go back to about 300 B.C. predating the Julian-Roman calendar. They were crude 'lifts' powered by human, animal, water or wheel power and probably did not have floor by floor push button operation.
          In 1835, a belt-driven, counter-weighted, steam-powered device was created in England.
          In 1857, a steam powered 'moving room' for a 5-story building was developed by Elisha Otis, founder of the most known name in elevator-dom, Elisha Elevators. OK, Otis Elevators if you prefer.
         The first escalator was on the old steel pier at Coney Island in 1897. Then, of course, there is the moving sidewalk envisioned no doubt by the future-seeing Wright brothers for expansive airport use.
