During an earthquake, as most people may recall from grade school, sometimes a strange phenomenon occurs in sandy soils known as liquefaction. And it is exactly what it sounds like — the ground that is made up of solid particles (sand) suddenly behaves like a liquid.
One of my favorite things about the new Apple TV is the screensaver that comes on after sitting idle for a bit. There are several slow-moving, but highly cinematic low flyovers of several iconic cities. The pass over Abu Dhabi in Dubai is stunning, to say the least.
In a country known for outlandish skyscrapers, and currently holding the record for the tallest building (Burj Khalifa), it should come as no surprise that it will also play host to the world’s first rotating skyscraper.
What is a rotating skyscraper and why would you want one? Mashable says:
The “Dynamic Tower,” which was proposed in 2008 by Israeli-Italian architect David Fisher, will feature 80 rotating stories that make the building look as if it’s in constant motion. Not to mention it’ll produce insanely cool views.
Each different story of the futuristic apartment building will rotate 360 degrees and move independently, so residents can control their speed or decide to stop movement altogether with simple voice commands. The downside? Each unit costs $30 million.

Back in June of 2015, a relatively unknown company by the name of Daqri introduced an augmented reality-enabled hard hat that they dubbed the Smart Helmet.
While there clearly is not yet massive adoption among the trades for a more than $1,000 hard hat, that doesn’t mean Daqri has ceased innovation. In fact, as Construction Junkie reports, the company unveiled its next wearable device purpose-built for the architecture, engineering and construction industry: Smart Glasses. (Not to be confused with Google Glass, of course…)
Here is a video showcasing Daqri’s products at this year’s Consumer Electronics Show:
And here is a case study produced by Autodesk and Mortensen showcasing the Smart Helmet:

Happy Friday, everyone! Every Friday I try to share a fun or interesting video to help kick off the weekend. But this Friday, we have not just one video, but an entire dozen videos.
Happy Friday, everyone! Today’s treat is a neat video that a builder made during the construction of his brother’s home.
The way he made this video is actually really cool. By programming a route for the drone, and then flying that exact route every day, Youtube user ChuckPPhotography then edited the video from around 32 to 34 of the passes together. The end result makes it look as if the entire home was constructed during a single pass of the drone.
My team and I have been working on something similar for our clients.
Check out the video below:
Ever since GoPro tried to launch their new line of drones for their adventure enthusiast market, problems have tarnished the normally stellar reputation for solid, quality-built imaging technologies. Forbes’ Ryan Mac wrote a thorough analysis of the saga, with the provocative headline, “The Sky Is Falling For GoPro.”
The article opens with a story of a disappointed customer’s experience:
Six days after the release of GoPro’s first-ever drone in October, Brian Warholak was itching to get airborne. As an employee at a Chesapeake, Va.-based government contractor, Warholak, 43, had few opportunities during the workweek to fly his new toy. But on Friday, he left his desk early, unpacked his GoPro Karma from its carrying case and set it on a manicured lawn near the company parking lot.
In the video of Warholak’s aeronautic excursion, the drone lurches upward, pausing for its master to pan the attached camera. What it captures initially is unremarkable: a nondescript office building and a mostly empty car park. Then, two minutes into the voyage, the device bricks. Its four propellers cut out and the drone begins a five-second, 170-foot freefall toward earth. It smacks a few tree branches on the way down for good measure and lands camera upward to capture its owner rushing to the crash. “F***, now where is the rest?” Warholak is heard saying on the video. “Son of a b****.”
Here’s the video in question:
Happy Friday, everyone. As a treat, here is a cool video from The Slo Mo Guys taken at a testing laboratory at Purdue University.
Reinforced concrete is truly an amazing product that is critical to the structural design and integrity of most modern buildings. The utility of the material comes from its ability to resist both compressive force as well as stretching. Concrete on its own has great compressive strength, but relatively little tensile strength without steel reinforcing.
That’s fairly common knowledge among most people in the building industry, but how many people can say that they’ve seen what rebar looks like when stretched to breaking?
Never judge a book by its cover, we are told from a very young age. (Marketers know better—consumers always judge a book, or anything else for that matter, by its cover.)
MIT’s Media Lab, in conjunction with the Georgia Institute of Technology, has developed a technology that will decipher text printed on the pages of a closed book. PBS has more:
This scanner exposes the contents of the concealed pages by relying on terahertz radiation. Terahertz waves mimic X-rays and soundwaves by being able to penetrate surfaces. Moveover, different chemicals — ink on paper for example — absorb terahertz radiation in different amounts. By beaming terahertz waves at a book, the MIT Media Lab device can skip through pages, but also tell the difference between blank and ink-filled parchment.
The gadget shoots these waves in short bursts, a portion of which bounce back whenever they encounter the small slivers of air between the pages. Meanwhile, computer scientists at Georgia Tech developed a sophisticated algorithm that deciphers these reflections when they return to the scanner.
It takes 13,760 individual nickel-cadmium cells, each about the size of a desktop PC and weighing about as much as a full-grown adult, to create the world’s largest battery. Vice’s Motherboard column has more:
On August 27, 2003, the Golden Valley Electric Association (GVEA), the cooperative that provides power to the Fairbanks area, powered up BESS, aka the Battery Energy Storage System. Larger than a football field and weighing 1,500 tons, BESS exists to ensure continuity of electric service. If the supply of electricity coming in from relatively distant coal plants to the south is interrupted, BESS kicks in until local power plants can be put online.
BESS can hold things down powerwise for all of seven minutes. It functions as what’s known as a spinning reserve. It’s a bridge between primary and backup power and is generally taken to mean some amount of excess generating capacity that is at any given time pre-synchronized to the grid. If power goes down, switching the spinning reserve on should be seamless.
Last June, I was in San Francisco for PCBC 2014, a construction industry event held at Moscone Center every other year (this year we’ll be partying in San Diego). Also at Moscone at that same time, in a different set of buildings, was the Google I/O event.
Being that it is such a huge event for Google, it meant that the faithful were also gathered. Which meant lots of Glass-holes, or Google Glass Explorers as they are officially known. (more…)
