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.

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.
Residents living near a Jersey City, New Jersey construction site were frightened as they watched “explosions” of smoke coming out of holes in the ground.
Smaller heavy construction equipment is the most likely to be stolen on a jobsite, but most of the time the thieves try to sell the equipment for money. On rare occasions, the thief just takes the machine out on the town for a joy ride and leading the police on some pretty frustrating pursuits. Early last year, a man in Florida stole a backhoe and lead police on a wild 3 hour chase as the hammer attachment drug along the asphalt throwing sparks the whole way. Just last week, police dash cam footage showed an 18 year old backing over a police cruiser, with an officer still inside, and then leading several other officers on a slow chase.
The Seattle Space Needle is not a normal building, which makes it a unique project to try to renovate. The iconic building is set to receive a $100 million renovation dubbed the Century Project that promises much better views thanks to new floor to ceiling exterior glazing. To prepare for the project, construction crews recently hoisted a 28.000 pound ring of scaffold to the tower’s Tophouse, around 400 feet in the air.
As we saw after the Lake Oroville Dam in California collapsed earlier this year, dam failures can have sudden and devastating effects. Recent footage showing raging muddy waters swallowing a construction site in a matter of seconds has been shared after river dam in Thatom, Loas failed.
Hurricane Irma ripped through the Caribbean and landed in South Florida a little over a week ago, sadly killing at least 50 people in Florida and causing plenty of property damage. High winds that accompanied the storm also caused the collapse of 3 construction cranes – two in Miami and one more in Fort Lauderdale. The crane in Fort Lauderdale was recently dismantled and the action was caught on video.
The Atlanta Falcons will play their home opener against the Green Bay Packers this Sunday, 9/17. As exciting as that is on a normal year, this year will be that much more special as it will also mark the opening of their brand new $1.4 million stadium, the Mercedes-Benz Stadium.
If you’ve ever wondered what the worst way to get rid of a puddle is, you’re about to find out.
In October of last year, officials in Dubai held a groundbreaking ceremony for the Dubai Creek Tower, a building which is expected to surpass the reigning “tallest building” champion, the Burj Dubai. Flash forward just a few short months and over a million hours of labor have already been spent on the project, all accident free.
New demolition videos are always fun to watch. You know what’s even better, though? A bunch of demolitions all at once.
While being prepared for demolition, the Grand Avenue Bridge in Glenwood Springs, Colorado unexpectedly collapsed to the railroad tracks below. Thankfully, no injuries were reported, but the local police chief said that workers had to flee the scene once the bridge section started to fall.
