If mankind perished today and our remains were dug up by future archaeologists from another species there is one thing that would become apparent quite quickly; we love to build things. From houses to bridges, sky scrapers to motorways we tear up resources lying around us and hammer them into useful and beautiful feats of engineering all the time. Sometimes those things really are inspiring examples of what we can achieve (the Millau Viaduct is taller than most sky scrapers) others are slightly more wacky (see the Hitler house). I’ve encountered quite a lot of ideas of the years that have left me enthused, impressed, awed, disturbed, incredulous and overall gobsmacked! Here are a few that instill all of those things…
There’s not enough land so let’s build more!
In 1929 a German man by the name of Herman Sogel had a rather…interesting idea. He believed that the 20th century would see the rise of both the U.S and a Pan-Asian nation that would displace Europe to the third power block of the world (personally I think he was a little over half right, the U.S did rise and many Asian nations are becoming more and more prosperous). To combat this he wanted to turn Europe and Africa into one continent. Yup, you read that right. The continent would be named “Alantropa” and would be created by damming the Strait of Gibraltar, over the years the Mediterranean sea would evaporate lowering its level by 200 metres. The plan had many aims, according to Sogel it would take nearly a century for the project to be completed. Hundreds of thousands of workers would be needed to build the damn in under ten years with potentially millions more required to turn the growing land of the Mediterranean into fertile farmland and colonise it. Alantropa would be powered by the dam which would produce Gigawatts of energy from hydroelectricity. Sogel saw this plan as a way of ensuring co-operation and peace in Europe as well as providing economic and industrial growth (later versions of the plan involved draining some of the mediterranean into Africa to produce three great lakes to turn the desert into more fertile land).
Alas his plan isn’t without its flaws. Aside from the building logistics the dam would cause massive ecological damage to the mediteranian and whilst Sogel had peaceful intentions towards Europe he had less savory attitudes towards Africans who he saw as in the way of an Expanding Europe. Still the audacity of this plan brings a smile to my face.
- Dubai City Tower
Those with a fear of heights need not apply
Of a slightly less extreme nature but by no means less imaginary is the Dubai City Tower proposal. Over recent years Dubai has become a hotspot for extravagant buildings like this, this and this. However of all the future proposals DCT really stands out. The tallest building in the world, the Burj Khalifa, stands at 800 metres (half a mile!). It is an extraordinary feat of engineering but the DCT would stand three times higher. The ‘tower’ would consist of multiple towers spiralling around each other before meeting hundreds of metres from the ground. With its extreme height the tower would not only have lifts but would have vertical trains that stopped every 100 floors. Each section of 100 floors would be a different “neighbourhood”. The plan isn’t just to build a tower but a vertical city. The DCT would be as self-sufficient as possible generating much of its own power from solar panels and wind farms attached to the outside of the towers, each neighbourhood would feature a sky atrium (domed garden) stretching between the spiralling towers to act as parks and focal areas for local businesses and communities. It’s still doubtful if this structure will ever be constructed and if it is it won’t be for decades. But this idea of arcologies (one building cities) has always intrigued me. The DCT will have everything in it; shops, homes, hospitals, schools, cinemas, hotels, offices….you name it and it will have it. Which intrigues me because of the simple odd fact that a person can be born, raised, work, marry, have kids and die all in the same building! Not that this is a desirable thing (it isn’t to me) it is merely extraordinary.
- Space Elevator
If you thought a mile and a half building was impressive how would you like to take a ride on a cable car….to space? The Space elevator is an old favourite of both science fiction and speculative engineering. The idea is pretty simple; at an altitude of 30,000 kilometres an object can be placed in orbit so that its orbital speed matches the rotation of the Earth. In other words an object in this ‘geostationary orbit’ would always hover over the same place on Earth. From a platform in this orbit a cable could be slowly lowered
down and attached to the corresponding place on the ground, then ‘climbers’ can run up and down this cable literally taking an elevator ride to orbit. Of course in reality the project is not that simple! There is no cable material that we can use at the moment that has the strength needed however we have started to produce materials that may be future candidates. Carbon nanotubes are small tubes of carbon nanometres wide made from just one atom thick sheets of carbon. They are the strongest materials known to man and we’ve been researching better methods of making them for years, the only problem at the moment is we can make small fragments but not thousands of kilometres! How the climbers would attach and actually climb is another problem however there are competitions between universities over this kind of thing already. A space elevator is daunting but its biggest advantage is the cost cutting that it would give to the space industry, that is costs of putting something into geostationary orbit would shrink to 1% of today’s price. On a purely weight cost that would change the cost of putting an average man to geostationary orbit from £1,200,000 to £5,000! That’s a pretty good amount allowing the average person to save up to go to space, not to mention the boom that the company/country who owns the elevator would get from trade in the space industry.
I hope you have enjoyed reading about these ideas, it’s things like this that still give me a passion for science (though my field focusses on the very small which is slightly less gobsmacking to see). If you’ve come across any crazy plans yourself feel free to let me know, I’m always keen to find the next thing that with that level of wow factor!
