Strong Tesla sales push Norway to 58% zero-emission share in March

Over 58 percent of passenger cars sold in Norway in March were zero-emission vehicles, according to Norway’s Road Traffic Information Office (OFV). That’s a new record for the small Scandinavian country that has long led the world in adoption of zero-emission vehicles.

The strong sales reflected pent-up demand for Tesla’s new Model 3, which only became available in large volumes in late February. The Model 3 accounted for 5,315 of the 18,375 vehicles sold in Norway in March, with the Model S and Model X selling another 500 vehicles combined.

“In 2018, Norway’s fully electric car sales rose to a record 31.2 percent market share from 20.8 percent in 2017, far ahead of any other nation,” Reuters reports.

If you include plug-in hybrid vehicles, Norway’s electric vehicle share reached around 50 percent in 2018. The comparable figure for the United States was around 2 percent.

Norway’s stunning sales of electric vehicles overall reflect aggressive policies by the Norwegian government to promote the shift away from vehicles with internal combustion engines that contribute to climate change. Norway imposes hefty taxes on conventional cars, but the country fully exempts electric (and hydrogen-powered) vehicles. As a result, electric vehicles are comparatively more affordable in Norway than they are in most other countries around the world.

Governments in Norway have made other efforts to promote electric vehicles, too.

“Capital city Oslo has made extraordinary efforts to promote EVs, including toll-free roads, HOV-lane access, free parking, and free charging,” CityLab reported in December.

According to Reuters, demand for electric cars is so strong in Norway that automakers have struggled to keep up. Tesla’s entry into the market represents a significant expansion of the availability of all-electric vehicles in the country.

March’s electric vehicle sales may prove to be a bit of an aberration driven by pent-up demand for the Model 3. But the head of the Norwegian Electric Vehicle Association, Christina Bu, told Reuters she expected electric cars to reach 50 percent of the new car market for 2019 as a whole.

A big question is what will happen if Norwegian authorities start to scale back some of the generous incentives offered for drivers of fully electric vehicles. For example, CityLab reports that electric cars’ exemption from the Value Added Tax could be phased out in 2020. Electric cars are also slated also lose their exemptions to some tolls this year. That could hamper Norway’s progress toward its goal of having all new vehicles be emissions-free by 2025.

Researchers designed a shape-shifting airplane wing

https://www.engadget.com/2019/04/01/nasa-mit-shape-shifting-airplane-wing/

If you’ve had a window seat next to the wing of an airplane, you’ve probably watched as flaps on the wing engage and disengage as a plane takes off and lands. That’s because in each phase of flight — take off, landing, cruising and maneuvering — the ideal wing parameters vary. Until now, we’ve made do by modifying rigid wings with hinged surfaces. But imagine if the entire wing could change shape — that’s what researchers led by NASA and MIT are working towards.

In a paper in the journal Smart Materials and Structures, the research team explains how it has radically redesigned the airplane wing. Their new structure is a lightweight lattice framework, made of thousands of repeating, tiny triangles of matchstick-like struts, covered in a thin polymer layer. Because this "metamaterial" is mostly comprised of empty space, it is extremely lightweight — less than one-thousandth the density of rubber. And, the carefully positioned struts allow the wing to change shape automatically in response to changes in aerodynamic loading conditions. Both factors could make aircraft more energy efficient.

This isn’t an entirely new concept. It was presented a few years ago, but now, the researchers have developed a way to manufacture the individual parts for the wing using injection molding. They’ve brought the time required to produce each part — a hollow cube with tiny struts along each edge — down from several minutes to just 17 seconds. While the meter-long model they created was hand assembled, the process was designed to be repetitive, so that in the future, small, autonomous robots will be able to assemble the wings.

The potential for a light-weight, shape-shifting wing raises questions about the ideal aircraft shape. With this technology, we might be able to break away from the "tube with wings" design and utilize a more efficient configuration — possibly an integrated body and wing structure. If the idea of watching an airplane wing change shape as you cruise at 30,000 feet alarms you, don’t worry yet. This is a long way from commercial airline-ready. In the meantime, it also has the potential to redesign other structures, like the wing-like blades of wind turbines.
