Feeling like you’ve had enough of this planet? Saturn’s biggest moon , Titan, is an attractive option for a space colony, according to new research. Amanda Hendrix of the Planetary Science Institute and Yuk Yung of the California Institute of Technology (Caltech) say the moon has enough energy sources to power a settlement the size of the United States. Saturn is home to 53 moons. But Titan, the largest, possesses its own atmosphere , which according to NASA is rare for a moon. It turns out Titan could also have an abundance of energy sources, according to Hendrix and Yung. They say there are options for solar power , wind power , hydropower , and nuclear power on the moon. They drew on the information we know about Titan and mathematics based on technologies we currently have on Earth. Related: Scientists Discover an Ocean of Water and Potential for Life on Saturn’s Moon The scientists said, “Once propulsion challenges are overcome, allowing humans to travel great distances quickly without incurring significant radiation damage, Saturn’s moon Titan is the optimal location in the solar system for an off-Earth human settlement.” Researchers know there are oceans of methane on Titan, which could offer a source of power or rocket fuel. Tidal power could also potentially energize some of the colony as experts have observed strong tides on the moon. In particular, an area called the Throat of Kraken, which John Hopkins University planetary scientist Ralph Lorenz likened to the Strait of Gibraltar, could be the perfect location for a settlement. Lorenz, who was not involved with the research, told New Scientist, “We’re pretty sure there’s a very strong flow of liquid back and forth every Titan day. If you want reliable power that you know is going to be accessible, that’s where I would go.” Hendrix and Yung did say they overlooked some details, because there’s still a lot we don’t know about Titan, but view their research as a first step. Their study was published in the Journal of Astrobiology and Outreach this week. Via ScienceAlert Images via Wikimedia Commons and NASA/JPL-Caltech/USGS

Comments Off on U.S. just generated 10% of electricity from solar and wind for the first time

Would anyone still like to claim renewable energy can’t power our world? It may take a while, but America is getting more and more of its energy from renewables, according to data from the United States Energy Information Administration (EIA). In March 2017, the country generated 10 percent of total electricity from solar power and wind power . This week the EIA reported more than 10 percent of the country’s total electricity generation came from wind and solar. In 2016, those two renewable sources made up seven percent of America’s electricity generation. Increased generating capacity enabled the U.S. to get more clean power . The figures include utility plants and small-scale systems. Related: The sweet moment California got a record 50% of its electricity from solar The EIA noted seasons impact how much clean energy will be generated from renewables. Wind electricity generation usually reaches its height in the spring in places like Texas and Oklahoma , but in California it usually peaks in the summer. Solar output is unsurprisingly best in the summer due to longer daylight hours. The EIA predicted the country would again generate over 10 percent of power from renewables again in April based on weather patterns from other years, but the numbers would dwindle to under 10 percent during the summer. Solar and wind combined tend to generate more power during either the spring or the fall, the administration said. Data from 2016 shows wind generated more power than solar in nearly all of the states, according to the EIA. Looking at the top 12 states, only California and Arizona obtained more power from solar than wind. The prize for most wind energy generated goes to Texas. And energy received from renewable sources was highest in Iowa , which generated 37 percent of power from renewables. Six other states got around 20 percent of power from wind and solar.

Incredibly rare two-headed porpoise found in the North Sea

Comments Off on Incredibly rare two-headed porpoise found in the North Sea

An unsuspecting fisherman recently stumbled across an incredibly rare two-headed dolphin. Only nine examples of conjoined twins have ever been found among cetaceans , according to Erwin Kompanje, curator of mammals for the Natural History Museum Rotterdam in the Netherlands . So he jumped at the chance to study a rare specimen of conjoined harbor porpoises caught the end of May by Dutch fisherman. But when he reached out to the fisherman, what happened next was a scientist’s nightmare. It’s not unheard of for trawlers to accidentally catch a porpoise. There are hundreds of thousands of the cetaceans near the coast of the Netherlands. But no one has ever caught conjoined twin harbor porpoises. The fisherman snapped photos, which made their way to Kompanje. He couldn’t wait to study the creature in the laboratory. Related: Fish with “human-like teeth” spotted in Michigan lakes Kompanje could tell the twins were male, and had likely recently been born – and he thinks they were born alive. They probably didn’t live for long; either they had two brains which might have told them to swim in different directions, or a single heart may have failed to pump enough blood to keep them alive. Conjoined twins are an extremely rare find. And these looked to be in good condition. Others that have been discovered were undeveloped fetuses – such as one found near Japan in 1970 in a dolphin’s womb – or have started to decompose, such as a dolphin with two beaks found in 2001. Kompanje reached out to the fisherman to try and obtain the specimen for study. But this story doesn’t have a happy ending for science. The fisherman thought it was illegal to catch the conjoined twins, so after the photographs, they tossed the creature back into the sea. Kompanje told The Washington Post, “For a cetologist, this is a real horror.” Based on the photographs he was still able to publish a paper in DEINSEA, the online journal of the natural history museum, joined by one scientist of the Royal Netherlands Institute for Sea Research and one from Wageningen Marine Research . Sadly, we may never know more about the rare twins. Via The Washington Post Images via Kompanje, E.J.O.; Camphuysen, C.J.; and Leopold, M.F.

Comments Off on China unveils train that travels on ‘virtual tracks’

City public transportation systems typically rely on a mix of trains and buses . But what if the two could be combined? Chinese company CRRC Zhuzhou Locomotive recently debuted a trackless train that could ease traffic and emissions in urban centers. The Autonomous Rail Transit (ART) uses sensors to run along invisible tracks on city streets. Train tracks on city streets could be a thing of the past if all goes well with the ART, recently unveiled in the city of Zhuzhou in the Hunan province in China , where it recently went on a trial run. Firstpost described the ART as the world’s first trackless train. Sensor technology enables the ART to glide over roads, helping it track a guiding system in place. The sensors send the information back to the train’s central control unit – what Firstpost described as a brain – to help it travel smoothly. Related: You won’t believe the interior of Japan’s jaw-dropping new train More than 300 people can ride on the ART, which is comprised of three carriages in its basic state but can expand to include five. It has rubber wheels with plastic cores. A twin-head system means the train never has to make a U-turn, according to Firstpost. The trackless train is over 103 feet long. The ART is powered by electricity , so it won’t give off carbon emissions as traditional trains do. It can travel at a speed of around 43 miles per hour. CRRC Zhuzhou Locomotive has reportedly been testing the ART technology for around four years, but the trackless train could finally be ready to roll out on the road in 2018. The company boasts a wide array of electric locomotives. Their Blue Locomotive won the title of Best New Energy Locomotive at the Berlin International Rail Transit Technology Exhibition.

Comments Off on Nations tallest timber building to rise in Portland

The nation’s tallest wooden high-rise will soon take shape in Portland , Oregon. Funded by a $1.5 million-dollar award from the U.S. Tall Wood Building Prize Competition , the innovative timber building, named Framework, will be built from domestically sourced and engineered wood products. LEVER Architecture designed the mixed-use high-rise as a beacon of sustainability with its use of low-carbon materials, green roof, and resilient design. Slated to begin construction this fall, the 12-story Framework building will comprise ground-floor bank and retail, five floors of office space, and five floors for 60 residential units with a mix of studios as well as one-bedroom and two-bedroom apartments. Nearly half of the 90,000-square-foot building will be zoned for affordable housing. The mixed-use building will also be primarily built of cross laminated timber and is designed to be fire- and earthquake-resistant. In a Framework press release: “Beneficial State Bank, a triple bottom line community bank, teamed with project^, a values-based commercial real estate developer; and Home Forward, the public housing authority for Multnomah County, Oregon to reimagine their existing Pearl District property in Portland, Oregon into Framework, the nation’s first wood high-rise building. The building seeks to develop a model for a sustainable urban ecology by promoting social justice , sustainable building, and economic opportunity thus yielding broad advancement of these objectives at a national scale.” Related: Magnificent timber skyscraper will sequester carbon and add greenery to Bordeaux Framework, which is expected to complete construction in late 2018, will likely be the nation’s first timber high-rise building with wood from the ground-floor as well as the first with exposed wood in North America. The building is also expected to use significantly less energy than a traditional building of similar size and function with energy savings of 60 percent when compared to code and water savings exceeding 30 percent compared to code. Framework is also expected to result in 1,824 tons of carbon dioxide emission offsets, equivalent to taking 348 cars off the road for a year. + LEVER Architecture

Comments Off on Electric cars could reach cost parity with conventional cars by next year

Are you eager to get your hands on a new electric vehicle,  but the price is too steep? You’re in luck – electric cars will likely reach cost parity with vehicles that have internal combustion engines by next year, and electric vehicles could be cheaper that gas by as soon as 2025, according to a new report by USB . The report makes it clear that while electric vehicles will still cost more than ICE cars, owning a new EV will be comparable to owning a gas or diesel car in the long-term. Analysts took into consideration the fuel costs, maintenance costs and other related expenditures related to owning all vehicles and used the information to determine that over time, the cost of owning a green vehicle is comparable to owning a conventional one. As Green Car Reports  reports , it is becoming more affordable to own an EV due to breakthroughs in battery capacity, charge times and a growing demand for environmentally-friendly technology. Part of the analysis required UBS to break down a $37,000 Chevrolet Bolt in order to estimate how much the vehicle cost to build. It was discovered that “the EV powertrain is $4,600 cheaper to produce than we thought and there is more cost reduction potential left.” Analysts continued that the 238-mile range Bolt costs around $28,700 to build and that GM is only expected to produce 30,000 Bolts in 2018. Therefore, there won’t be a huge incentive for it to be profitable. Related: UK solar smashes record, supplying 25% of electricity demand On the other hand, the Tesla Model 3 is expected to be produced in numbers as high as 500,000 by 2018. When extras are added on to the base price of the Model 3 at $35,000, the company is expected to break even. UBS declared that electric vehicles are the “most disruptive car category since the Model T Ford” and that though total sales for electric cars is still relatively small, global EV sales will reach 14% by 2025 (4.2 million vehicles). Europe is expected to take the lead in this department, selling 30% of the world’s electric cars within eight years. Now that EVs will soon cost the same to own as a car or truck with an ICE, a massive shift is expected to take place within the auto industry . + UBS Via  Green Car Reports

Comments Off on Watch Toyota’s flying car take its first test flight

Have you ever wanted to ride in a flying car? In just a few years, you might soon be able to! Several companies are working on developing this technology, and Toyota-backed Cartivator recently made progress on this goal by taking its flying car for a tentative test flight. Though the vehicle still needs a lot of work, the Japanese-based startup company is certain the car will be ready to fly in time for the 2020 Olympic Games in Tokyo. The test flight can be seen in the Associated Press video below. Because the early prototype of the car is little more than structural scaffolding, batteries, and rotors, it doesn’t look like much. However, it is able to get about head height before returning to the ground. Unfortunately, the trial had to be called off after the propellers were damaged several attempts later. CNet reports that Cartivator Resource Management, a small tech company, received nearly $400,000 in investment from Toyota to bring the flying car concept to life. This isn’t the only futuristic technology Toyota is seeking to develop. After ending a partnership with Tesla , the company seeks to become a global leader in electric automobiles. When the Toyota-backed vehicle is completed, it should be able to take off from public roads and travel at speeds up to 100 kmph (62 mph) when flown at approximately 10 meters. At present, the team’s goal is to complete the flying car by the 2020 Olympic games in Tokyo so it can light the flame.

Comments Off on New NASA probe will get closer to the sun than any spacecraft in history

Humanity has never before touched the sun , but that’s about to change. NASA is sending the Parker Solar Probe to the sun in 2018, and will get closer to the star’s surface than any other spacecraft in history. They say the landmark mission “will revolutionize our understanding of the sun.” The Parker Solar Probe mission – which NASA describes as humanity’s first visit to a star – will take us closer to the sun than ever before. The probe will need to endure extreme radiation and heat as it ventures into the outer part of the sun’s atmosphere, the corona. NASA says the Parker Solar Probe will gather information on the corona and on the evolution and origin of solar wind . Related: Teen creates world’s lightest satellite and NASA is sending it to space A 4.5-inch-thick carbon-composite shield will protect the instruments inside the spacecraft from crazy temperatures of around 2,500 degrees Fahrenheit. The various instruments will be able to image solar wind, and study plasma and energetic particles and magnetic fields. Even though we’re around 93 million miles away from the sun on average, solar wind disturbances can affect us here on Earth. They impact what NASA calls space weather, which can interfere with our satellites . NASA says much like the seafarers of old had to learn about the ocean, now we must learn more about the space environment. The mission holds claim to another first: the first time NASA has named a spacecraft after a living person. Once called the Solar Probe Plus, NASA this week renamed the probe for astrophysicist Eugene Parker, a professor emeritus at the University of Chicago. His work decades ago provided a foundation for much of our knowledge about stars’ interaction with worlds orbiting them. Parker, who will turn 90 this month, said in a statement, “The solar probe is going to a region of space that has never been explored before. It’s very exciting that we’ll finally get a look. One would like to have some more detailed measurements of what’s going on in the solar wind. I’m sure that there will be some surprises. There always are.” Via NASA ( 1 , 2 ) Images via John Hopkins University Applied Physics Laboratory and JHU/APL

Comments Off on San Francisco bike shop lets you trade in car for e-bike

A new bike store in the Bay Area of San Francisco has come up with an interesting way to get people to reduce their transportation footprint. Electric bikes make a great alternative for commutes in cities like San Francisco , but many people find the hefty price tag of an e-bike prohibitive. The New Wheel solves that by allowing patrons to trade in their old vehicles for an e-bike – and a healthier lifestyle. San Francisco’s 74 hills don’t make for pleasant bike commutes – unless you’ve got an e-bike to help you. The New Wheel is making it easier for people to obtain e-bikes. Patrons can bring in their old cars, and the bike shop will take notes on the car’s condition and mileage, and send the information to Roadster.com . 48 hours later they make patrons an offer, and will even come pick up the old car and deliver a check. Ideally patrons will spend some of that money on an e-bike at The New Wheel, but aren’t required to do so. Related: Propella’s lightweight electric bike rides like a regular bike Shop co-founder Brett Thurber told Fast Company, “We’ve always been in the business of trying to figure out ways to get people out of cars and onto bikes. With all the traffic and even parking, it’s not convenient anymore, in many instances, to own a car. I think the thing we’re up against is just habit.” The New Wheel has adopted other ideas from the car industry to help people get used to the idea of owning a bike as their main vehicle. They offer financing for e-bikes and allow people to trade in their old e-bikes. They even offer roadside assistance; if bikers get a flat tire The New Wheel will pick them up twice a year and give them a free ride up to 30 miles. + The New Wheel Via Fast Company Images via Pixabay and Tom Lowenthal on Flickr

Over 700 North American bee species are heading towards extinction

Comments Off on Over 700 North American bee species are heading towards extinction

Life without honeybees would be less than sweet – it’d mean a lot fewer fruits, vegetables, nuts, and seeds. But honeybees aren’t the only bees we need to worry about. The future of many Native North American and Hawaiian bee species is also in peril: a new study found that more than half of the region’s native bee species are declining , and nearly one in four native bee species is imperiled and at risk for extinction. Image © Dominik Scythe via Unsplash A new report by the Center for Biological Diversity entitled “Pollinators in Peril: A systematic status review of North American and Hawaiian bees” outlines the importance of these native bee species by valuing their financial importance as well as their ability to help ecosystems thrive. As fruit-pollinators, native bee species are worth more than three billion dollars, yet their work pollinating wild flowers and plants is equally important in maintaining diverse and colorful flora. As if the information regarding known declining populations wasn’t cause enough for alarm, the author warned that this study and other bee studies simply don’t have enough data on thousands of native bee species – many of which are found in areas of “great environmental degradation” – to determine if they are at risk. Image © Jenni Peterson via Unsplash Related| This could be the United States’ first endangered bee species The study cites loss of habitat due to agriculture, heavy use of pesticides , climate change, and urbanization as large drivers of the native bee populations’ decline and endangerment. Lead author Kelsey Kopec said, “It’s a quiet but staggering crisis unfolding right under our noses that illuminates the unacceptably high cost of our careless addiction to pesticides and monoculture farming.” The report includes case studies of five distinct bee species around the country that are in great peril, including the wild sweet potato bee, which is the only known species in the world in its genus, and the sunflower leafcutting bee, which is the largest and most distinctive leafcutting bee on the continent. While a casual eye might be tempted to group these bee species together, their unique habits and contributions to varied ecosystems highlight their individual importance and fragility.
