Why a V-shaped plane may make a whole lot of sense
When it comes to climate change, today's airplane pollution is a real problem.
- A new partnership between the Delft University of Technology and KLM Royal Dutch Airlines has been announced along with a plan for a striking new plane.
- The Flying-V is a plane that's all wing, and promises a 20% reduction in fuel use.
- Riding in the Flying-V as it banks may not be for the faint of heart.
As more of us take to the skies more often and for longer trips, carbon emissions from aircraft are becoming a real problem. Currently, some 2.5 percent of total global CO2 emissions come from airplanes, and that number is on the rise. It's estimated that by 2050, they'll be responsible for 5 percent of the worldwide carbon budget — that's 43 gigatonnes of pollution, a dirty mix of CO2 and nitrogen oxides. The source of all this is, of course, the fuel consumed by the craft.
To address this, Delft University of Technology (TU Delft) has announced that it's partnering with KLM Dutch Royal Airlines on the design of a new type of plane dubbed the "Flying-V." It was actually the brainchild of TU Berlin student Justus Benad, developed while working on his thesis. The plan is to debut a flying scale model and display a full-sized cabin section as part of the October commemoration of KLM's 100-year anniversary. What's exciting about the Flying-V is that it would use 20 percent less full than the most advanced plane of today, the Airbus 350. What's worrying is that its bold shape may not fly too well.

In a press release, the dean of aerospace engineering at TU Delft, Henri Werj, discussed the project:
We are incredibly pleased to be able to cooperate with our trusted partner KLM on our combined mission to make aviation more sustainable. Radically new and highly energy-efficient aircraft designs such as the Flying-V are important in this respect, as are new forms of propulsion. Our ultimate aim is one of emission free flight. Our cooperation with KLM offers a tremendous opportunity to bring about real change.
The Flying-V, as its name suggests, is shaped like that letter of the alphabet. It's really all wing, with no central fuselage. The passenger cabins, cargo hold, and fuel tanks live in both of the Flying-V's wings. The wingspan of the craft would be the same as the Airbus 350, though it's about 20 meters shorter in length. Nonetheless, the Flying-V would accommodate the same number of passengers — 314 — and have the same kerosene fuel capacity — 160m3 — even though it this amount of fuel would take the Flying-V farther. The plane's smaller overall size would incur less aerodynamic resistance.
The partners also envision the new plane and form factor as an opportunity to improve the cabin experience for passengers, though the details on this have not been announced.
The problem with the Flying-V

An issue that could keep the plane from every becoming a reality has to do with the manner in which planes turn in the sky: They bank as they change course, one wing tipping up as the other tips down.
In conventional craft, we sit along the spine of the fuselage, and so turns are typically fairly easy to stomach. However — and this has been a problem with previous v-wing designs — when you're seated outward in a wing far away from that center axis, banking feels far more extreme, and may feel like more of a rollercoaster than a tolerable means of getting the family to Disneyworld. Still, the actual deployment of the Flying-V is estimated to be 20-30 years off, so there's plenty of time to assess the severity of the problem and hopefully devise a remedy.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Technology may soon grant us immortality, in a sense. Here's how.
- Through the Connectome Project we may soon be able to map the pathways of the entire human brain, including memories, and create computer programs that evoke the person the digitization is stemmed from.
- We age because errors build up in our cells — mitochondria to be exact.
- With CRISPR technology we may soon be able to edit out errors that build up as we age, and extend the human lifespan.
The controversial herbicide is everywhere, apparently.
- U.S. PIRG tested 20 beers and wines, including organics, and found Roundup's active ingredient in almost all of them.
- A jury on August 2018 awarded a non-Hodgkin's lymphoma victim $289 million in Roundup damages.
- Bayer/Monsanto says Roundup is totally safe. Others disagree.
The pizza giant Domino's partners with a Silicon Valley startup to start delivering pizza by robots.
- Domino's partnered with the Silicon Valley startup Nuro to have robot cars deliver pizza.
- The trial run will begin in Houston later this year.
- The robots will be half a regular car and will need to be unlocked by a PIN code.
Would you have to tip robots? You might be answering that question sooner than you think as Domino's is about to start using robots for delivering pizza. Later this year a fleet of self-driving robotic vehicles will be spreading the joy of pizza throughout the Houston area for the famous pizza manufacturer, using delivery cars made by the Silicon Valley startup Nuro.
The startup, founded by Google veterans, raised $940 million in February and has already been delivering groceries for Kroger around Houston. Partnering with the pizza juggernaut Domino's, which delivers close to 3 million pizzas a day, is another logical step for the expanding drone car business.
Kevin Vasconi of Domino's explained in a press release that they see these specially-designed robots as "a valuable partner in our autonomous vehicle journey," adding "The opportunity to bring our customers the choice of an unmanned delivery experience, and our operators an additional delivery solution during a busy store rush, is an important part of our autonomous vehicle testing."
How will they work exactly? Nuro explained in its own press release that this "opportunity to use Nuro's autonomous delivery" will be available for some of the customers who order online. Once they opt in, they'll be able to track the car via an app. When the vehicle gets to them, the customers will use a special PIN code to unlock the pizza compartment.
Nuro and its competitors Udelv and Robomart have been focusing specifically on developing such "last-mile product delivery" machines, reports Arstechnica. Their specially-made R1 vehicle is about half the size of a regular passenger car and doesn't offer any room for a driver. This makes it safer and lighter too, with less potential to cause harm in case of an accident. It also sticks to a fairly low speed of under 25 miles an hour and slams on the breaks at the first sign of trouble.
What also helps such robot cars is "geofencing" technology which confines them to a limited area surrounding the store.
For now, the cars are still tracked around the neighborhoods by human-driven vehicles, with monitors to make sure nothing goes haywire. But these "chase cars" should be phased out eventually, an important milestone in the evolution of your robot pizza drivers.
