gephyrophobiacs: look away now
this is the sky bridge in langkawi, malaysia, a stunning cable-stayed bridge which actually curves around the single support column from which it’s suspended, 687 metres above sea level. whilst the upside is incredible views, the downside for gephyrophobiacs is that you’re seemingly placing all your trust in a single, relatively thin lattice tower which also happens to be standing at an angle.
the world’s most astounding agricultural engineering project
the rice terraces of the philippine cordilleras, if laid out end to end, would stretch halfway round the globe. if this ingenious feat had been accomplished in recent times the clearly enormous task would have seemed more than impressive, however the fact that it was completed thousands of years ago without the use of modern apparatus and machinery takes the terraces and integrated irrigation systems to a whole new level.
extremely impressive shiny balls
the enormous 34ft diameter shiny ball pictured above goes by the name of ‘la géode’. this stunning metallic structure houses a 1000m² hemispheric imax screen at the ‘cité des sciences et de l’industrie’ in paris. it was designed in 1983 by french architect adrien fainsilber and then realised by engineer gérard chamaillou. it’s apparently one of the largest geodesic domes on earth.
man vs mountain: avalanche control structures
one of the places i’d refuse to set up home would have to be at the bottom of a mountain with a history of avalanche activity. unfortunately for some that choice doesn’t seem to exist and after reading a post over at the highly recommended blog pruned yesterday the frightening world of avalanche survival systems nearly became an obsession, for a couple of reasons.
the grand shaft - amazing military engineering
here’s an incredible piece of wartime engineering - the grand shaft in dover. built between 1806 and 1809 during the napoleonic wars, this triple spiral staircase was used as a rapid route for soldiers making their way from the clifftop barracks to the town of dover and it’s harbour below. without it the troops had to navigate badly maintained winding roads from top to bottom.
hamburg’s unique elevator tunnel
running under the river elbe in hamburg is a beautiful tunnel like no other. this 1/2 kilometre ‘technical marvel’, known as the ‘old river elbe tunnel’, was built in 1911, sits 24 metres below the river and connects central hamburg with the shipyard island of steinwerder. what makes the tunnel unique are the entry points on each side of the river: rather than just driving straight into the tunnel, vehicles enter a freight elevator which slowly descends to the tunnel below, the tunnel then taking traffic to a similar elevator on the opposite side which lifts them back to ground level.
i hope those pillars are strong
below is the recently (2003) extended runway at funchal airport in portugal. the original 1400m runway was notoriously short and, as a result, sometimes dangerous for landing planes. the runway extension won the iabse’s ‘outstanding structures award’ and rightly so: due to an obvious lack of land, engineers have supported the extension on 180 pillars, each 70m high. on the last photo you can see the presumably noisey car park that now lives under the end of the runway.
4 more stupidly cool research facilities
the joint european torus (jet) is the largest nuclear fusion experimental reactor on earth and is also a unique facility for researching fusion technology. jet is an example of a ‘tokamak’, a machine which produces an extremely strong, doughnut shaped magnetic field in order to confine a plasma. in jet’s case these plasmas can reach temperatures in excess of 100 million degrees centigrade…
israel’s bizarre uphill subway system
maybe i live a sheltered life but i’ve never been more surprised by a public transport system than when i came across this little beauty. it’s called the carmelit, it runs underground in the citry of haifa, israel and it’s the country’s only subway system. due to the city being located on the side of mount carmel, the entire single track ‘funicular’ system has been designed to accomodate the incline, hence the strange stepped stations and diagonal trains.
the forgotten sound mirrors
from 1915 onwards these huge eerie concrete structures started popping up along the uk coast, all built with one purpose: to provide the military with an early warning system in relation to incoming aircraft. their construction was pretty much limited to the uk and arrived just before radar technology as we know it became widespread.
