Wind has been used for over a thousand years, with the first known windmill built between 500-900 AD in Persia (known as Iran, today). For centuries to come, wind would be used to power grain mills and scoop up water out of a river or stream. Surprisingly, the first windmill, or wind turbine, to actually produce electricity was built way back in 1887 in Scotland. Inventor James Blyth used the turbine to power his vacation home.
Now, wind turbines for electricity are slowly gaining in popularity, but the race is on to see who can make them more and more efficient. Just like solar power, not all of the energy gained from wind can be used.
How do Wind Turbines Work?
Wind turbines are obviously more suitable to windy environments, as it uses the wind to turn its blades. The blades typically rotate at 18 RPM, which is pretty slow, so a series of gears are installed inside the shaft that rotate at 1800 RPM. Those gears then power a generator, which begins to create electricity. The video below gives great information for those looking to learn more about how wind turbines work.
Locogen Wind Turbine Timelapse
Now, for the main attraction. The 330KW wind turbine in North Ayrshire, Scotland. The structure stands 200 feet high (61m) and is Locogen’s Enercon E33 turbine. In the video, you’ll see the entire construction process, from beginning to end and it’s filmed up close, so you can see pretty much every detail. Typically, timelapse videos only show an overview of the entire site, so you can barely tell what’s actually being done, so it’s nice to see a company take a different approach.
Demolition by implosion videos are always fun to watch. Adding an element of water makes them even more dramatic, though it’s probably not great for the ecosystem. Late last week, a one mile long, 23 year-old bridge in China was imploded in front of a crowd of spectators and caught on camera.
Excavators are a vital piece of equipment on many construction sites all over the world. They’re also very expensive machines that deserve to be treated well. They’re also the 3rd most commonly stolen piece of construction equipment.
Cranes are an extremely useful and important piece of equipment on the majority of construction sites. They can also be extremely dangerous if they are not understood or respected.
As the US is experiencing our own natural disaster, by way of Hurricane Florence, China is being hit badly by a Typhoon Mangkhut. According to Independent, the storm has caused a crane, which was being used on a 22-story housing development, to crumble. That collapse was caught on camera by neighbors.
It’s hard to believe that it has been 17 years since the terrorist attacks on the World Trade Center in New York City. I came to the realization this week that many of the men and women that are about to enter the workforce will never have a true understanding about how the country felt that day and how it responded. New York is still responding to this day and, even though the skyline will never quite be the same, there are new buildings in their place paying tribute to those who lost their lives that day.
Astronomy and the planets and solar systems within it, are a source of wonderment and awe for many people. Planetariums, which are educational facilities for the hands-on and interactive learning about astrology, can be found across the world. China is currently building a pretty spectacular planetarium in Shanghai, the country’s biggest city.
There have been a few devastating structural collapses across America and the world this year. In March, an under construction pedestrian bridge collapsed in Florida, killing 6. In Colombia, ten workers were killed when a large section of a bridge being built collapsed. Both of those tragedies happened while the structures were still being built, but a recent collapse in Texas has a bit of a different story.
As America’s infrastructure is continually described as “crumbling,” I thought it would be a good time to take a look back to how highways were paved around 70 years ago. A lot has changed in the past seven decades, but you might be surprised by how similar paving still is.
On Monday morning, a 13 story building in Miami Beach that was being prepped for demolition suddenly collapsed, injuring one Project Manager that was struck by debris.
One of the best parts (for me, anyway) of large developments that cost hundreds of millions of dollars being built is being able to learn about different construction methods that can reduce costs or deliver the project sooner than traditional methods. The Crown Sydney, a future 890 foot tall tower in Australia, is using a method called “top down construction” to shorten their project schedule and avoid additional hazards on the $740 million project.
