Buoyancy and Upthrust

Started Nov 2

 

Welcome, Nelson!

The SpaceShaft is an application of what I call a “combined method of construction and transportation”. At http://spaceshaft.org I explain in a qualitative way its attributes and the method itself, from which other applications can be derived.

I am a mechanical engineer that has worked and has a great deal of interest in naval engineering.

Some years ago, when I heard about the CNT Space Elevator and the currently popular design using ground based lasers, I could not help myself thinking about the challenges of relocating an asteroid, transporting the CNT spools to space, the down to Earth deployment, and the many other issues with anchoring, laser targeting, maintenance, ..., etc. Don’t get me wrong, I am not in anyway dismissing the popular system of anchor, tether, car and laser, however pretty much as the system is proposed i,e, a combination of technologies, so I believe, shall be the "end result", if a space elevator is ever to be constructed, so my invention is just but an apportation to resolve some of the current problems. In fact, as it is with many other things, probably some of the proposed systems shall be displaced or entirely replaced by other better suited systems. After all, that is the reason NASA called upon the private and public inventiveness to this challenge!

The reason why I am introducing myself at this website, and disclosing some information of the patents I’ve applied for, is because of a very simple reason; such a thing like a space elevator is a monumental endeavor and if I, like others, wish to see a "functional space elevator" constructed during our lifetimes not only I need to assist others in their endeavors but vice-versa to.

Doing what I’m trying to do, cannot be the work of a one man only, neither should the benefits of such a system be in the hand of a few, but instead humanity! Particularly at these taxing times, in which humanity is at a fork on the road; that is, humanity’s destiny is to face climate change, ecological disintegration, and some other minor problems like the current recession. Worth mentioning is the fact that, beside the space elevator application itself, my method of combined construction and transportation can have other more earthly applications; perhaps in the field of atmospheric sequestration of green house gases, or of power generation by the “stack effect”, etc..

At this time, the SpaceShaft is still in its theoretical stages, and because I am avoiding the financial overhead a company imposes the endeavor is not formalized within a such a framework. Much of the prototyping cost has either been financed by myself or by 3rd parties, to whom I am very grateful for their trust.

Working with me are other professionals whom started by doing peer review and now hold the rights of co-inventors and shareholders of a future business. These are Eng. Patrick Vankeirsbilck and Prof. Dean Vucinic. Their CVs (unlike mine,) are easily found by doing an internet search or going to our website (my apologies for being so lazy). I certainly hope that our team becomes more extended including professionals in other domains that we really need to fulfill for the constitution of a full fledged organization.

Challenge: Can anyone estimate the theoretical upthrust power of a buoyant column 50 kilometers tall and 100 meters in diameter, ignore other factors such as structural mass, anchoring and mooring, etc.?
