Solar roofs are an obviously popular choice for those interested in conserving energy, but traditional panels are extremely clunky and expensive. Tesla and CEO Elon Musk announced last year that they have solved that issue, which the impending release of Tesla Solar Roof, which look like a traditional roof shingle.
Tesla obviously knows what they’re doing in the realm of energy usage, as their high powered electric vehicles are also extremely efficient. After harnessing what they already know about electric efficiency and also acquiring SolarCity for over $2 billion, Tesla claims that their solar roofs will cost less than a traditional roof when combined with utility bill savings. In combination with Tesla’s new Powerwall 2, which stores energy for use at night, the roof is expected to be able to power lights, sockets and refrigerator of a 4 bedroom house for a full day, but can be scaled to any size. Power output of each Powerwall is 7kWh.
The Solar Roof shingles are going to be available in 4 different styles: Tuscan glass tile, slate glass tile, textured glass tile, and smooth glass tile. Those interested in the roof are able to put their name on a waiting list on Tesla’s website. Elon Musk also recently announced on Twitter that the company would begin taking orders in April. The first installations are to begin later in the year.
As far as durability goes, Musk shared a video in his presentation announcing the new solar roof, which showed a weight being dropped on a terra cotta, clay, slate, and tesla glass tile. The 3 traditional roof systems shattered under the weight, but the Tesla glass was only slightly dented.
The solar roof is made up of 3 layers: a high efficiency solar cell, covered by a color louver film, which is then covered by tempered glass. The color louver film creates the look of the tiles.
You can watch the video of the announcement below, which has some additional information about the roofs, starting at 7:25:
Rapid growth and the industrialization are the major contributors to China’s noted air quality issues. 4 years ago, the Chinese government issued a “war on pollution” aiming to improve air quality and reduce other environmental hazards, such as land and water contamination. Air quality is at its worst in the winter months across the country, due to households relying more on coal power to heat residents’ homes.
Asphalt is one of the world’s most popular pavement materials. Because of that, researchers and scientists are constantly looking for ways to improve upon it. Additives have been included in some asphalt mixes for years to improve strength, but recently researchers have been getting pretty clever with the types of additives they’re testing.
As great as a product as asphalt is, there’s no doubt that there is room for improvement. Scientists all over the world are trying to solve its most common issues, such as potholes, cracking, ice build-up, and storm water drainage. Los Angeles is now tackling another issue with the material: heat island effect.
In March of this year, Elon Musk announced that Tesla would begin taking orders on their Solar Roof Shingle concept. Tesla Solar Roof is a solar power roof system that eliminates the need for bulky solar panels installed over top of traditional roof materials. Instead, the shingles themselves, which come in a variety of different styles, are the solar panels.
At the company’s second quarter earnings report, Tesla announced that the first solar roof installations have been completed.
Standard vertical elevators have had it too good, for too long. After the first cable dependent elevator was unveiled in 1857, not much has changed in the elevator industry. They’re still using cable systems and still only going up and down. But not anymore. ThyssenKrupp has officially made a multi-directional elevator a reality.
There’s no shortage of company’s trying to improve the world’s roadways. Asphalt and concrete each have their own disadvantages, especially when maintenance environmental factors are taken into consideration. Plastic is a major problem for landfills, as well, as it can take an estimated 500 years to fully decompose. One UK company believes they can solve both maintenance and environmental problems through the use of recycled plastic.
The Massachusetts Institute of Technology (MIT) is constantly researching ways to improve construction process and materials, like this material 10 times the strength of steel, or this solar cell that’s lighter than a soap bubble, or this “reversible concrete.” This time the Institute is showing off its autonomous robot that can spit out building structures on site within hours.
One of the most challenging issues with modular construction, of any kind, is the sheer size and weight of many of the components that need to be transported and lifted in place once onsite. That presents a specifically tough situation for jobsites that are not easy to get to. Arup, a design, engineering, and consulting team in the United Kingdom, has developed and successfully implemented what they say is the “world’s first modular glass-fiber, reinforced polymer bridge.” You may remember Arup from their testing of a “living wall” scaffolding cover that we wrote about last year.
Snow causes all kinds of travel nightmares and not just on the roads. Snow and ice can cause major airline delays and flight cancellations. Because of these issues (and the large amounts of money to be gained by solving them) several different groups of researchers have been hard at work figuring out ways to reduce and remove snow and ice from pavement without the need for chemicals and snow plows. The first technology to get a full scale test slab installed at an American airport, however, came from Iowa State University professor Halil Ceylan.
Maybe I’ve had my head in the sand for a while (forgive the pun right out of the gate), but I've recently found out that the world is suffering from a shortage of sand. The New York Times reports that the increasing demand of sand from manufacturing and construction in combination with rising sea levels and human development of shores is reaching crisis levels. Sand is used in plenty of construction activities, from mortar to concrete to brick and asphalt. We use a LOT of it. In fact, concrete production takes a whopping 80 percent of all the sand that is mined. So what can we do? One company says the answer is to drink more beer.
