Comments Off on Massive iceberg draws tourists to tiny Canadian town

A new natural attraction drew scores of tourists to a small town of around 500 people in Newfoundland, Canada over Easter weekend. A massive iceberg appeared near the coast, and photographers dashed to the area to snap pictures. The Southern shore highway close to Ferryland filled with traffic over the weekend as tourists came to view the impressive iceberg. The Newfoundland coast area is commonly called iceberg alley due to the ice blocks that float down during the spring from the Arctic , but this particular huge iceberg might stay right where it is, according to Ferryland Mayor Adrian Kavanagh, who told The Canadian Press it’s the biggest one he’s ever seen in the area.

Local Don Costello told CBC News the iceberg probably won’t be moving unless winds keep blowing because it’s stuck on shallow ground. He estimated the iceberg’s highest point is roughly 150 feet. The BBC reported more icebergs are drifting through iceberg alley than is normal for this point in the year, with hundreds of icebergs in the Atlantic. This particular iceberg has moved around some and broken apart, but it appears it’ll stick around for a while. That’s good for tourism – a tour operator told CBC News they’re happy when the icebergs are grounded, and his company is receiving dozens of online bookings every day. Iceberg tourism season technically hasn’t even started – there are a few weeks to go. Costello told CBC News, “I met a couple of people and they were looking for somewhere to get a bowl of soup or a sandwich or something, and there’s only two places here…and they don’t open until the 24th of May.” Via the BBC and CBC News Images via Randy Wheeler on Facebook , Fantasy RV Tours on Facebook , and Alison Thorne on Facebook

Solar Impulse co-founder aims to make electric aviation a reality with new company

Electric high-speed trains have been zipping passengers across Europe and Asia for decades. Now the era of affordable electric cars is beginning with the introduction of the Chevy Bolt and Tesla Model 3. But what about aviation? Could the friendly skies one day join electric trains and cars as an alternative to fossil-fueled transportation, which is polluting the air and contributing to climate change?  Solar Impulse ’s co-founder André Borschberg is aiming to make electric propulsion in the aviation industry a reality with a new company he co-founded, H55 . “Electric air transport will undoubtedly disrupt the aviation industry,” said Borschberg. “15 years ago, when I started with Solar Impulse, electric propulsion was anecdotal. Today it is a major development path of every large aeronautical organisation as well as attracting many start-ups and new players. What is science fiction today will be the reality of tomorrow.” Related: Solar Impulse successfully completes solar-powered flight around the world The Switzerland-based venture will focus on the entire propulsion chain — from the energy source to thrust and power to pilot interface and control systems. H55 has already successfully completed more than 50 hours of flight testing with its electric demonstrator aircraft, aEro1. Borschberg piloted eight of the 17 legs of Solar Impulse 2’s around-the-world flight, including flying for five days and five nights non-stop over the Pacific Ocean — the longest flight ever recorded in a single-pilot airplane. Solar Impulse 2 departed Abu Dhabi in March 2015, returning there in July 2016 after flying around the world (including a nine-month delay for technical repairs). + H55 Images via H55

Scientists use Martian dust to 3D print tools

Food and transportation aren’t the only aspects of a mission to Mars scientists must consider. Limited cargo space means to obtain tools or similar items, astronauts may need to make use of resources available on the red planet – like dirt. Four Northwestern University researchers were recently able to utilize a Martian dust simulant to 3D print building blocks and tools . NASA started looking into space 3D printers back in 2013 to manufacture repair parts or tools. Now Northwestern scientists have used lunar and Martian dust simulants approved by NASA to 3D print tools in a process the university described as simple, scalable, and sustainable. Related: 6 space farming projects that could save the human race The researchers drew on a technique they call a 3D-painting process; engineer Ramille Shah said using 3D paints “really open up the ability to print different functional or structural objects to make habitats beyond Earth.” They’ve created a 3D ink and printing method they’ve used to print 3D graphene and hyperelastic “bone.” They made their 3D paints for this project with simple solvents, biopolymer, and the dusts, which are similar to real Martian and lunar dust in terms of composition and particle size and shape. The structures they printed are more than 90 percent dust by weight. The 3D-printed material is flexible, tough, and elastic, kind of like rubber. It can be shaped, folded, cut, or rolled. In addition to tools the team 3D-printed interlocking bricks Shah said are like LEGOS . According to Northwestern, “…this work highlights the potential to use a single 3D printer on another planet to create structures from all kinds of materials.” The journal Nature Scientific Reports published the research online in late March. Shah and another Northwestern professor, who was not a co-author on this paper, are working together on ways to fire the 3D-painted objects in a furnace to make them harder – more like ceramic.
