Researchers at Durham University and the UK’s Nautical Almanac Office compiled nearly 3, 000 years of celestial records and found that with every passing century, the day on Earth lengthens by two milliseconds as the planet’s rotation gradually winds down. The Guardian reports: The split second gained since the first world war may not seem much, but the time it takes for a sunbeam to travel 600km towards Earth can cost an Olympic gold medal, as the American Tim McKee found out when he lost to Sweden’s Gunnar Larsson in 1972. For those holding out for a whole extra hour a day, be prepared for a long wait. Barring any change in the rate of slowing down, an Earth day will not last 25 hours for about two million centuries more. Researchers at Durham University and the UK’s Nautical Almanac Office gathered historical accounts of eclipses and other celestial events from 720BC to 2015. The oldest records came from Babylonian clay tablets written in cuneiform, with more added from ancient Greek texts, such as Ptolemy’s 2nd century Almagest, and scripts from China, medieval Europe and the Arab dominions. The ancient records captured the times and places that people witnessed various stages of solar and lunar eclipses, while documents from 1600AD onwards described lunar occultations, when the moon passed in front of particular stars and blocked them from view. To find out how the Earth’s rotation has varied over the 2, 735-year-long period, the researchers compared the historical records with a computer model that calculated where and when people would have seen past events if Earth’s spin had remained constant. The astronomers found that Earth’s spin would have slowed down even more had it not been for a counteracting process. Since the end of the most recent ice age, land masses that were once buried under slabs of frozen water have been unloaded and sprung back into place. The shift caused the Earth to be less oblate — or squished — on its axis. And just as a spinning ice skater speeds up when she pulls in her arms, so the Earth spins faster when its poles are less compressed. Changes in the world’s sea levels and electromagnetic forces between Earth’s core and its rocky mantle had effects on Earth’s spin too, according to the scientists’ report in Proceedings of the Royal Society.

Earth’s Day Lengthens By Two Milliseconds a Century, Astronomers Find
Google said today it will power 100 percent of its sprawling data centers and offices with renewable energy starting next year. The company said today it has bought enough wind and solar power to account for all the electricity it uses globally each year. In comparison, 44 percent of Google’s power supplies came from renewables last year. From a blogpost: To reach this goal we’ll be directly buying enough wind and solar electricity annually to account for every unit of electricity our operations consume, globally. And we’re focusing on creating new energy from renewable sources, so we only buy from projects that are funded by our purchases. Over the last six years, the cost of wind and solar came down 60 percent and 80 percent, respectively, proving that renewables are increasingly becoming the lowest cost option. Electricity costs are one of the largest components of our operating expenses at our data centers, and having a long-term stable cost of renewable power provides protection against price swings in energy.

Google Says It Is About To Reach 100 Percent Renewable Energy
Zero-emissions cars are popping up left and right, but motorcycle design has been a little late to the game. Yet, all-electric motorcycles and are zooming down the streets in increasing numbers. With varying engine sizes, charging times and driving ranges, each new electric motorcycle that hits the market offers something unique. From far-out futuristic designs that look like something Batman would ride to bikes that could have driven off a Star Wars set , cutting-edge electric motorcycles have broken the early trend that suggested EVs ought to look like dorkier versions of their fossil fuel counterparts. Other electric motorcycles target ambitious performance standards — from blistering top speeds to longer driving ranges and even some fun features like built-in LED effects . BMW Motorrad VISION NEXT 100 Leave it to BMW to create an electric motorcycle fit for the world’s most popular superhero. The self-balancing BMW Motorrad VISION NEXT 100 is an all-electric, zero emissions ride that looks like it was designed for Batman himself than your average biker, with a sleek, matte black frame and futuristic style. Unveiled last month in Los Angeles, BMW’s newest electric motorcycle features a triangular design similar to the luxury automaker’s previous bikes, but this time it is comprised mostly of carbon fiber and polished aluminum. The Motorrad’s ability to stand on its own aids in the ride’s stability and safety — BMW is even suggesting that riders can go without a helmet. While we wouldn’t recommend that approach, BMW created a smart visor for the rider to wear, which replaces both the windshield and rearview mirrors while enabling the rider to access navigational data and other information on bike performance. AP Works Light Rider The world’s first 3D-printed electric motorcycle came hot off the presses earlier this year. Light Rider was created by APWorks, a subsidiary of Airbus, and the fully electric bike boasts a 37-mile range and a top speed of 50 miles per hour. The prototype sports a frame that looks more akin to an alien skeleton than a standard cycle, and it weighs only 13 pounds — around 30 percent less than the average e-bike. With the motor and all its wiring hidden inside the casing, this bike looks like something straight out of a science fiction film. Only 50 of these futuristic high-end bikes will be created, and each will be sold for a whopping $56, 000. Concept Honda Chopper A few years back, someone created a concept motorcycle that would get the attention of any Stormtrooper in its vicinity. The Honda Chopper stems from the mind of designer Peter Norris, who typically works in video games. The Chopper concept calls for a different approach to motorcycling, and Honda seems like the carmaker that might be able to get away with a launch of something this wild. With electric motors mounted right on the wheels, the Chopper has a lower center of gravity than the standard motorcycle, which lends to its stability and handling. No word on whether Honda R&D is actually considering production on such a thing, but the concept is pretty intriguing. Johammer J1 The Johammer J1 electric motorcycle has promised to do what none before could deliver: 125 miles of all-electric range on a single charge. The bike is able to exceed the energy storage capacity of the average e-bike thanks to a larger, enclosed compartment for its larger batteries. Manufactured in small quantities in Austria, the Johammer J1 runs on high-density batteries created specifically for this all-electric cycle. The e-bike initially sold for $31, 860. Voxan Wattman Upon its release in 2013, the Voxan Wattman was known as the world’s most powerful electric motorcycle, thanks to its 12.8kWh battery pack. The all-electric motorcycle can go from zero to 60 mph in a mere 3.4 seconds for a quick, emissions-free getaway. Perhaps one of its best features, though, is that the battery can be fully charged in about half an hour – and that gives the bike a range of around 111 miles. Launched as a concept bike, the Voxan Wattman was primed to take on the motorcycle market, but the company dropped the project after it was plagued by a host of complications. The Tron Lightcycle In 2011 Parker Brothers Choppers created the Lightcycle : an all-electric motorcycle that doubles as a moving light show. Outfitted with an array of LEDs, the Lightcycle is capable of traveling as fast as 100mph and has a 100-mile driving range after just 35 minutes of charging time — but its makers insist that isn’t the point. The motorcycle’s contoured frame and wheels are all lined with glowing LEDs, which accent its hardened steel frame, and a carbon fiber and fiberglass body. Driving an emissions-free chopper like this at night would be a sure-fire attention-getter in any urban environment.

Six amazing all-electric motorcycles
At Universal Studios in Los Angeles Tesla CEO Elon Musk showed off the company’s solar roof-top panels and new Energy initiative. It also showed off its new $5, 500 Powerwall 2 high-capacity residential batteries and Powerpack 2 for businesses. Musk and company have been teasing the photovoltaic cell-embedded rooftop panels for a few weeks . It’s also using the announcement of the new product as an explanation for why its acquiring Solar City. Musk said that if the merger doesn’t go through, the launch of the new tiles will be difficult. During the event, Musk sort of talked about the price of the panels. He said that when a house has these the “installed cost is less than a normal roof and the cost of electricity.” But there was no concrete pricing announced. The event was held on a Hollywood backlot where Solar City and Tesla had installed non-operating solar panels onto the houses you might recognize for the TV show, Desperate Housewives . The houses didn’t attract any attention before the event because they appeared so normal. He also showed off a house with a Tuscan style glass tiles that to the naked eye, you would be hard-pressed to notice that the roof was actually sucking up the energy of the sun. “People love their homes and we want them to be better, ” Musk said. Of course the entire equation requires batteries for a home to keep it lit up when the sun goes down. Tesla says the new Powerwall 2 will power a four bedroom house with lights, refrigerator and other appliances for an entire day. Musk said that they expect to start installing the glass tiles in summer 2017 and for the roofs to last a very very long time. “We expect this to have two or three times the longevity of asphalt. It’s really never going to wear out. It’s got a quasi-infinite lifetime. It’s made of quartz, ” he said. Tesla and Solar City are working with 3M on the coating on the glass tiles. Tesla has just come off an impressive quarter where it posted a profit for the first time in two years . It also announced earlier this month that all vehicles produced going forward would have the hardware capable of full autonomous driving . Developing. Source: Tesla

(credit: Qualcomm) Qualcomm is promising to launch its first 5G modem in 2018, even though basic standards for 5G have yet to be established , nor even which part of the radio spectrum it will use. Dubbed the Snapdragon X50, the San Diego chipmaker says its new modem will be able to deliver blindingly fast peak download speeds of around 5Gbps. The X50 5G will at first operate with a bandwidth of about 800MHz on the 28GHz millimetre wave (mmWave in Qualcomm jargon) spectrum, a frequency that’s also being investigated by Samsung, Nokia, and Verizon. However, the powers that be have far from settled on this area of the spectrum, with 73GHz also being mooted. In the UK, Ofcom is investigating several bands in a range between 6GHz and 100GHz. As the industry as a whole is a long way from consensus, this could be Qualcomm’s bid to get the final frequency locked down well before 2020—the year that 5G is expected to reach any kind of consumer penetration.

By Cat DiStasio We all love our battery -powered gadgets, but portable power cells can be devastating to the environment. Fortunately, recent developments have proven that greener batteries are coming in the not-too-distant future. Engineers are replacing toxic components with less harmful materials ranging from leaves to sugar . Other innovations on the rise look to nature to help make batteries last longer, perform better and leave less of a trace once they’ve been discarded. This gold nanowire-based battery , for instance, was created by accident and could make lithium ion batteries obsolete, while this single-use battery dissolves in water when its job is done, making it easier to reuse its components. The leafy green battery A team of University of Maryland researchers sought to develop an inexpensive material to serve as their batteries’ negative terminal (anode). In the end, they found the perfect material right on campus. The team found that oak leaves could be heated to 1, 000 degrees Celsius to destroy the existing carbon structures, and then introduced the electrolytes to the leaf’s natural pores for absorption. The result is a plant-based anode that performs similarly to traditional battery components. Research is ongoing to test other natural materials, such as peat moss, banana peels and melon skins in search of the nature-based battery of the future. A graphene battery that charges in an instant Scientists are working hard to create rechargeable batteries that can withstand more use. Australia’s Swinburne University has created a new graphene-based battery that shows rapid charging abilities — and it has enough durability to last virtually forever. Super strong graphene replaces lithium in the battery’s supercapacitor, addressing all of the shortcomings of that widely used material while also reducing the environmental impact of battery production. The graphene-based supercapacitor allows the new battery to charge to 100 percent power in just a few seconds, it can withstand many more recharging cycles and it also costs less to produce than traditional lithium-ion batteries. Sweet and cheap: a battery fueled by sugar A Virginia Tech team developed a sugar battery that lasts longer than any previous sugar-based prototypes could. Maltodextrin, a polysaccharide made from the partial hydrolysis of starch, is isolated from natural sugar and then used as fuel. When combined with air, the battery releases electrons from the sugar solution to generate electricity. Sugar is cheap and abundant, so it makes for a battery that’s not only affordable, but biodegradable as well. Gold-based battery that doesn’t die An accidental discovery by researchers at University of California, Irvine led to a technological breakthrough that could leave lithium-ion batteries in the dust. The team built a nanowire battery using gold and some new-fangled materials, and it can be recharged hundreds of thousands of times without slacking in the performance department like lithium-ion batteries are known to do over time. The battery consists of protected electrode nanowires made from a thin core of gold, surrounded by layers of manganese dioxide and a Plexiglas-like electrolyte gel. Although the team had initially been searching for innovations to increase the power capacity of batteries, they stumbled upon this method of building a battery that can last basically forever without showing any signs of wear. Self-destructing battery dissolves in water A self-destructing battery won’t come in handy for everyone, but the development of this dissolving energy storage device is a key innovation for certain applications where single-use batteries are currently being left behind to pollute the surrounding environment. Created by a team at Iowa State University, this battery is designed to self-destruct when triggered by light, heat or liquid, so it’s well suited for military applications and other so-called “transient” devices that require a power source for a finite amount of time. Certain medical devices and environmental sensors might fall into this category, and since the battery simply dissolves in water once it has served its purpose, its lasting impact on the environment is approximately nil. Edible saltwater battery Although there’s probably no need to eat a battery, you could chow down on parts of this one if you really felt compelled. In an attempt to demonstrate how natural and eco-friendly his company’s new battery really is, Jay Whitacre at Aquion Energy has eaten parts of the saltwater-based battery, and lived to tell. The battery’s components are comprised largely of naturally derived materials such as dirt, cotton, carbon and saltwater acting as an electrolyte solution. While hardly a delicious meal, the battery components demonstrate an ecological sensitivity not often found in the energy storage field. This battery is designed for large-scale jobs, such as providing backup power for a home or business equipped with a renewable energy source, such as wind or solar. It can also be charged up with off-peak grid power, to save money on energy use during peak times when prices are higher.
