Travel by Rocket From New York to Tokyo in 30 Minutes?

U.S. billionaire innovator Elon Musk has unveiled plans for a new rocket that would allow passengers to travel from one continent to another in about 30 minutes.

At a presentation Friday in Adelaide, Australia, Musk showed a video of images of a rocket taking off in New York and landing in various places around the world, including Tokyo and Shanghai.

He said the New York-Shanghai trip could be done in 39 minutes, while a trip from Bangkok to Dubai would take 27 minutes and Tokyo to Delhi would be 30 minutes.

He added that the cost per seat should be about the same as full fare economy in an aircraft.

Musk noted there is no weather outside the Earth’s atmosphere to interfere with travel times and said that once you are beyond the atmosphere, “it would be as smooth as silk, no turbulence, nothing.”

“If we are building this thing to go to the moon and Mars, then why not go to other places on Earth as well?” Musk said.

Musk, who founded and runs the company SpaceX along with the electric luxury car company Tesla, has long been making plans for rockets to travel to Mars.

Musk said SpaceX plans its first trip to Mars in 2022, carrying only cargo with a key mission to find the best source of water on the Red Planet. That mission would be followed by the first manned mission in 2024. He said the company was aiming to start construction on the first spaceship in the next six to nine months.

Musk said space flights to enable people to travel from one continent to another could help to pay for future missions to Mars.

Top 5 Songs for Week Ending Sept. 30

We’re liberating the five most popular songs in the Billboard Hot 100 Pop Singles chart, for the week ending September 30, 2017.

Last week featured a rare treat: a Hot Shot Debut single in the Top Five. We’re happy to announce that this week, history repeats itself.

Number 5: Sam Smith “Too Good At Goodbyes”

It happens in fifth place, where Sam Smith re-surfaces.

Sam tallies his sixth Top 20 – and his third Top Five – hit, “Too Good At Goodbyes”. Back home in the U.K., the news is even better, where it becomes Sam’s sixth number one. This is the opening single from his upcoming second album. It’s been three years since he dropped “In The Lonely Hour.” Sam says he wants the album to update us on his love life… which according to him is still terrible.

Number 4: Luis Fonsi & Daddy Yankee Featuring Justin Bieber “Despacito”

Luis Fonsi, Daddy Yankee, and Justin Bieber aren’t suffering too terribly with “Despacito”: the former 16-week champ weakens a slot in fourth place.

Fans of Daddy Yankee are helping him aid victims of natural disasters. Last week, he went on social media to elicit donations for those devastated by Hurricane Maria in the Caribbean, and the massive earthquake in Mexico. Working with several charities, he collected donations of diapers, batteries, bottled water and other essentials. Daddy Yankee also joined forces with Feeding America, which will bring food donations to 78 municipalities in Puerto Rico.

Number 3: Logic Featuring Alessia Cara & Khalid  “1-800-273-8255”

Logic bumps it up two slots to third place with “1-800-273-8255” featuring Alessia Cara and Khalid.

This is now the highest-charting single in Hot 100 history with a telephone number as its title. Back in 1982, the rock band Tommy Tutone peaked at number four with “867-5309/Jenny.” Actually, no fewer than seven songs bearing phone number titles have made it into the Hot 100.

Number 2: Cardi B “Bodak Yellow (Money Moves)”

Cardi B remains a strong contender at number two with “Bodak Yellow (Money Moves).” 

Cardi recently said she was going to push back her album, originally slated for an October release. Posting on Twitter, rapper J Cole advised her not to pressure herself to release an album…just keep dropping strong singles.

Number 1: Taylor Swift “Look What You Made Me Do”

Taylor Swift stays strong atop the Hot 100 for a third week with “Look What You Made Me Do.”

Did you know Taylor threw a Halloween party last year? Naturally, it drew top celebs: model Gigi Hadid was there along with Camila Cabello, who dressed as a “Grandma Who Couldn’t Find Her Cat Because She Sat On It.”

We’ll find our way to number one next week and we hope you’ll join us.

IMF Chief tells Central Bankers to not Dismiss Bitcoin

Christine Lagarde, the head of the International Monetary Fund, has a message for the world’s central bankers: Don’t be Luddites.

Addressing a conference in London on Friday, Lagarde said virtual currencies, which are created and exchanged without the involvement of banks or government, could in time be embraced by countries with unstable currencies or weak domestic institutions.

“In many ways, virtual currencies might just give existing currencies and monetary policy a run for their money,” she said. “The best response by central bankers is to continue running effective monetary policy, while being open to fresh ideas and new demands, as economies evolve.”

The most high-profile of these digital currencies is bitcoin, which like others can be converted to cash when deposited into accounts at prices set in online trading. Its price has been volatile, soaring over recent years but falling sharply earlier this month on reports that China will order all bitcoin exchanges to close and one of the world’s most high-profile investment bankers said bitcoin was a fraud.

For now, Lagarde said, digital currencies are unlikely to replace traditional ones, as they are “too volatile, too risky, too energy intensive and because the underlying technologies are not yet scalable.”

High-profile hacks have also not helped, she noted. One notable failure was that of the Mt. Gox exchange in Japan in February 2014, in which about 850,000 bitcoins were lost, possibly to hackers. Following that, Japan enacted new laws to regulate bitcoins and other cryptocurrencies.

But in time, she argued, technological innovations could address some of the issues that have kept a lid on the appeal of digital currencies.

“Not so long ago, some experts argued that personal computers would never be adopted, and that tablets would only be used as expensive coffee trays, so I think it may not be wise to dismiss virtual currencies,” Lagarde said.

Lagarde’s comments appear at odds with the views of JPMorgan Chase CEO Jamie Dimon, who this month described bitcoin as a fraud and said he’d fire any of his traders if they caught dealing in the digital currency.

In a speech laying out the potential changes wrought by financial innovations, Lagarde also said that over the next generation, “machines will almost certainly play a larger role” in helping policymakers, offering real-time forecasts, spotting bubbles, and uncovering complex financial linkages.

“As one of your fellow Londoners – Mary Poppins – might have said: bring along a pinch of imagination!”

Researchers Seek Cheaper, Energy-efficient Ways of Producing Clean Water

Having enough clean drinking water has been a challenge in many parts of the world, whether it’s a place where water is scarce or abundant. The World Health Organization finds 3 in 10 people globally still lack safe drinking water at home.

The U.S. Department of Energy has just announced it is providing up to $15 million in funding for projects to develop solar desalination technology to create freshwater at a lower cost. Even before the announcement, researchers had been working on better ways to desalinate water.

“We can take any quality of water that we’re starting with and we can turn it into any quality of water that we desire at the end, and the only real challenge or limitation has to be overcome is how much does it cost and how much energy does it take to go from here to here,” said Eric Hoek, co-founder and Chief Executive Officer of Water Planet Inc.

Cheaper energy

Water treatment plants are largely driven by electricity. A cheaper source of energy is the sun.

“What’s changed in the last five to 10 years, solar has gotten cheap,” Hoek said.

“The only reason that that has not taken over the world at this point is that it’s still intermittent. The sun goes up and it comes down. You have power when it’s up and don’t when it’s down. What you need to make that a continuous base load is you need batteries, which you can charge up during the day, discharge at night, and the cost of batteries is still currently pretty high.”

Household system

Qilin Li at Rice University is building a desalination system that uses solar energy with broad drinking water applications for “individual households or small communities that live in remote locations, especially those who don’t have access to municipal water supply, don’t have a stable supply of electricity. This technology can be an ideal technology,” Li said.

Her solar-powered desalination system can “also benefit megacities in developing countries that don’t have the extensive water and power infrastructure we enjoy here in developed countries, and that kind of relief perhaps in not providing all the water for the whole city, but can relieve some of their need or dependency on the power grid,” Li said.

The goal of Li’s system is to make it modular and cost efficient so it could either meet the needs of a small household or a large community.

Li and her team created a reactor to distill water using heat from the sun. Water turns into vapor, goes through a porous membrane and becomes pure water. Li says a low cost coating on the membrane developed at Rice University makes this unique.

“So it (membrane) harvests the sunlight, converts the photon energy in the sunlight to heat highly efficiently to generate water vapor, and it also serves a separation function to keep the contaminants on the dirty side of the membrane and only allow pure water vapor to go through,” Li said.

Waste heat

The sun is not the only low cost source of energy. Amy Childress’ lab at the University of Southern California (USC) looks at how waste heat that comes from manufacturing can be used as a resource.

“With waste heat you’re going to have cycles and spikes. We’ve gone out to the field, measured waste heat at an industrial site. We come back. We plug that into our system, so that we can repeat that waste heat curve over and over and watch the response of membranes to the waste heat,” said Childress, who directs USC’s Civil and Environmental Engineering Department’s environmental engineering program.

Her lab looks at how waste heat would impact the longevity and properties of a membrane.

Childress says the work in her lab will be helpful in the development of better membranes.

Filters in demand

There is high demand for membranes that help produce clean water. Water Planet’s PolyCera® membrane used to treat wastewater, is finding broader applications.

“We have a lot of interest now around the world, not just in industrial wastewater, but we’re actually making point-of-use under-the-sink water filters for applications in India, in China and here in the U.S. We’re making membranes that are being tested now for deployment offshore in sea water desalination to produce drinking water in barges and in platforms,” Hoek said.

With nearly 30 percent of the world’s population lacking safe drinking water at home, researchers will continue to work on harnessing free energy to clean water.

Telescope Moves Forward on Land Sacred to Native Hawaiians

A long-running effort to build one of the world’s largest telescopes on a mountain sacred to Native Hawaiians is moving forward after a key approval Thursday, reopening divisions over a project that promises revolutionary views into the heavens but has drawn impassioned protests over the impact to a spiritual place.

Hawaii’s land board granted a construction permit for the $1.4 billion Thirty Meter Telescope atop the state’s tallest mountain, called Mauna Kea, but opponents likely would appeal the decision to the state Supreme Court. Protesters willing to be arrested were successful in blocking construction in the past.

“For the Hawaiian people, I have a message: This is our time to rise as a people,” said Kahookahi Kanuha, a protest leader. “This is our time to take back all of the things that we know are ours. All the things that were illegally taken from us.”

No construction soon

Telescope officials don’t have any immediate construction plans and will consider its next steps, said Scott Ishikawa, a project spokesman. Officials previously have said they want to resume building in 2018.

“In moving forward, we will listen respectfully to the community in order to realize the shared vision of Mauna Kea as a world center for Hawaiian culture, education and science,” TMT International Observatory Board Chairman Henry Yang said in a statement.

Richard Ha, a Native Hawaiian farmer who supports the project, urged opponents to avoid confrontation.

“The possibility of getting the best telescope in the world … I don’t feel is the right battle to fight,” he said. “It will hurt our own people.”

While opponents say constructing the telescope will desecrate Mauna Kea, supporters tout the instrument’s ability to provide long-term educational and economic opportunities.

“This was one of the most difficult decisions this board has ever made,” state Board of Land and Natural Resources Chairwoman Suzanne Case said in a statement about the 5-2 decision.

Plans for the project date to 2009, when scientists selected Mauna Kea after a five-year around-the-world campaign to find the ideal site for what telescope officials said “will likely revolutionize our understanding of the universe.”

The project won a series of approvals from Hawaii, including a permit to build on conservation land in 2011. Protesters blocked attempts to start construction. Then in 2015, the state Supreme Court invalidated the permit, saying the board’s approval process was flawed, and ordered the project to go through the steps again.

​Protests from the beginning

Protests disrupted a groundbreaking in 2014 and intensified after that. Construction stopped in 2015 after 31 demonstrators were arrested for blocking the work.

A second attempt to restart construction a few months later ended with more arrests and crews retreating.

Mehana Kihoi said being arrested while praying on the mountain was one of the most traumatic experiences of her life. She started going there to help heal from domestic violence, Kihoi told the land board earlier this month.

“For years, I carried grief and pain … until I went to the mauna,” she said, using the Hawaiian word for mountain.

Culture over money

Kanuha, a protest leader, dismissed the millions that telescope officials have paid toward educating youth on the Big Island in science, technology, engineering and math. So far, $3.5 million has been paid into the educational fund, even while the project’s construction permit was invalid.

That money isn’t the answer to improving the lives of Native Hawaiian youth, Kanuha said. Revitalization of language and culture through Hawaiian-focused education is what’s important, he said.

A group of Native Hawaiian telescope supporters formed a group called Perpetuating Unique Educational Opportunities. Some members had been against the telescope in the past, said the group’s attorney, Lincoln Ashida.

“We believe that with increased opportunities for children, that results in stronger families, which in turn benefits our community,” Ashida told the board.

A group of universities in California and Canada make up the telescope company, with partners from China, India and Japan. The instrument’s primary mirror would measure 98 feet (30 meters) in diameter. Compared with the largest existing visible-light telescope in the world, it would be three times as wide, with nine times more area.

Mauna Kea, a dormant volcano, has been the first choice, telescope officials said, calling it the best location in the world for astronomy. Its summit provides a clear view of the sky for 300 days a year, with little air and light pollution. They selected an alternate site in Spain’s Canary Islands if the telescope couldn’t be built in Hawaii.

Hundreds of Species Arrive in US on Japanese Tsunami Debris

Nearly 300 species of fish, mussels and other sea critters hitchhiked across the Pacific Ocean on debris from the 2011 Japanese tsunami, washing ashore alive in the United States, researchers reported Thursday.

 

It is the largest and longest marine migration ever documented, outside experts and the researchers said. The scientists and colleagues combed the beaches of Washington, Oregon, California, British Columbia, Alaska and Hawaii and tracked the species to their Japanese origins. Their arrival could be a problem if the critters take root, pushing out native species, the study authors said in Thursday’s journal Science.

 

“It’s a bit of what we call ecological roulette,” said lead author James Carlton, a marine sciences professor at Williams College, in Williamstown, Massachusetts.

It will be years before scientists know if the 289 Japanese species thrive in their new home and crowd out natives. The researchers roughly estimated that a million creatures traveled 4,800 miles (7,725 kilometers) across the Pacific Ocean to reach the West Coast, including hundreds of thousands of mussels.

 

Invasive species is a major problem worldwide with plants and animals thriving in areas where they don’t naturally live. Marine invasions in the past have hurt native farmed shellfish, eroded the local ecosystem, caused economic losses and spread disease-carrying species, said Bella Galil, a marine biologist with the Steinhardt Museum of Natural History in Tel Aviv, Israel, who wasn’t part of the study.

‘Jaw-dropping diversity’

A magnitude 9 earthquake off the coast of Japan triggered a tsunami March 11, 2011, that swept boats, docks, buoys and other man-made materials into the Pacific. The debris drifted east with an armada of living creatures, some that gave birth to new generations while at sea.

 

“The diversity was somewhat jaw-dropping,” Carlton said. “Mollusks, sea anemones, corals, crabs, just a wide variety of species, really a cross-section of Japanese fauna.”

 

The researchers collected and analyzed the debris that reached the West Coast and Hawaii over the last five years, with new pieces arriving Wednesday in Washington. The debris flowed across the North Pacific current, as other objects do from time to time, before it moved north with the Alaska current or south with the California current. Most hit Oregon and Washington.

 

Last year, a small boat from Japan reached Oregon with 20 good-sized fish inside, a kind of yellowtail jack native to the western Pacific, Carlton said. Some of the fish are still alive in an Oregon aquarium. Earlier, an entire fishing ship, the Sai sho-Maru, arrived intact with five of the same 6-inch fish swimming around inside.

Co-author Gregory Ruiz, a Smithsonian marine ecologist, is especially interested in a Japanese parasite in the gills of mussels. Elsewhere in the world, these parasites have taken root and hurt oyster and mussel harvests and they hadn’t been seen before on the West Coast.

Much of debris is plastic

 

The researchers note another huge factor in this flotilla: plastics.

 

Decades ago, most of the debris would have been wood and that would have degraded over the long ocean trip, but now most of the debris — buoys, boats, crates and pallets — are made of plastic and that survives, Carlton said. And so the hitchhikers survive, too.

 

“It was the plastic debris that allowed new species to survive far longer than we ever thought they would,” Carlton said.

 

James Byers, a marine ecologist at the University of Georgia in Athens, who wasn’t part of the study, praised the authors for their detective work. He said in an email that the migration was an odd mix of a natural trigger and human aspects because of the plastics.

 

“The fact that communities of organisms survived out in the open ocean for long time periods (years in some cases) is amazing,” he wrote.
