Researchers want to save shrinking Swiss glacier with 4,000 snow machines

Climate change is shrinking the Morteratsch glacier in Switzerland by around 98 to 131 feet every single year. Scientists led by Johannes Oerlemans of Utrecht University think they have an answer: artificial snow . 4,000 snow machines could recycle water into flakes that could hopefully preserve the famous glacier. Oerlemans presented the idea in late April at the European Geosciences Union annual meeting. He thinks artificial snow blown over the glacier during the summer could help protect its ice . Sunlight melts that ice, but as Oerlemans said, “as long as there’s snow on top, the ice beneath is unaffected.” According to New Scientist, if artificial snow was put over the glacier, it would be the first attempt in the world to protect a glacier on this large of a scale. Related: Scientists hatch crazy $500 billion plan to refreeze the Arctic Morteratsch draws tourists every year because its snout, or the end of the glacier, is easy to reach. Oerlemans said, “Locals claim it’s the only place you can reach a glacier from a wheelchair.” But the natural wonder has dwindled from an 1860 length of five miles to 3.7 miles today. Residents of nearby Pontresina asked Oerlemans and other colleagues to save their treasure. They’d heard white fleece coverings on the smaller Diavolezzafirn glacier helped it grow around 26 feet across a decade. Oerlemans thinks Morteratsch could win back a length of around 2,625 feet in 20 years with some type of covering. A few centimeters of artificial snow fanned across a 0.2 square mile plateau high upon the glacier could help save it, according to the scientist. That may sound like a relatively small area, but it would still take 4,000 snow machines, using water recycled from meltwater lakes near Morteratsch. Scientists are starting with a pilot project at Diavolezzafirn’s foot. They’ll blow snow over an artificial glacier to see how the method works. If they’re successful, researchers hope the Switzerland government might fund the project with the millions of Euros required for Morteratsch.

Elon Musk’s Boring Company video envisions underground LA as a crazy slot car race

Comments Off on Elon Musk’s Boring Company video envisions underground LA as a crazy slot car race

Boldness has never been a problem for Elon Musk , who decided to improve the experience of driving through Los Angeles – while the rest of us just honk our horns. After tweeting in December that the city’s notorious traffic was driving him nuts, he immediately set up The Boring Company to dig underground tunnels for relief from the congestion above ground. Now the company has released a YouTube video envisioning exactly what that system might look like. Check it out after the jump. Forget freeway on-ramps. In the future imagined by The Boring Company, cars simply drive onto a sled-like device on a city street that lowers them into the tunnel network. The sleds then connect to a track and shoot the cars under Los Angeles at speeds of 124 miles per hour, according to the video. A supercomputer could direct car movement to potentially eliminate accidents.

Musk recently spoke more about The Boring Company at TED2017, in addition to Tesla and SpaceX . The interviewer, TED Head Curator Chris Anderson, asked how much of the entrepreneur’s time the project takes up, and Musk estimated just two or three percent. “This is basically interns and people doing it part time…we bought some secondhand machinery…it’s kind of puttering along but it’s making good progress,” he said in the talk. Anderson joked The Boring Company is “what an Elon Musk hobby looks like.” One can imagine all sorts of regulatory hurdles his hobby company would have to jump before they could build the vast tunnel network envisioned in the video, but if anyone can do it, it’s probably Musk. If you want to learn more, settle in over a lunch break; Musk’s TED talk is 40 minutes long and can be watched here . + The Boring Company Via Gizmodo Images via screenshot

Barcelona to Build the World’s First Carbon-Neutral Indoor Ski Slope

Comments Off on Barcelona to Build the World’s First Carbon-Neutral Indoor Ski Slope

The designers behind Ski Dubai’s artificial ski slope , Snow World and B01 Arquitectos have teamed up to improve on the original design with the world’s very first carbon-neutral indoor ski slope. If approved by Barcelona’s City Council, this new Snow World will be one component of the Zona Franca redevelopment project which aims to transform a neglected industrial complex into a thriving residential area. Both the ski dome and housing area will be powered with renewable energy while the extreme cooling necessary to maintain an artificial ski slope in a warm country will be achieved by harvesting the byproduct of converting Liquefied Natural Gas back into its gaseous form.
