How to charge your phone if the power goes out (and why you SHOULDN'T use the 'battery hack' taking Twitter by storm) - Daily Mail

'You don't want to put anything past 4. 5 volts. As extreme weather events have left thousands without power, the question of how to keep your phone fully charged is more important than ever. This device is the most manual way to give your phone a charge. There are also premium versions that hold enough power to charge your phone a half dozen times. Charging your phone this way would take a lot of labor - three hours of cranking, to be exact. It started on Kickstarter as Trinity, a device folds together into a 12-inch cylinder and then unfolds into a vertical turbine that be used to charge USB devices. It's a $60 hand crank that is roughly the size of a smartphone itself and has a retractable crank you can turn to charge your phone. 'That’s really really bad,' he echoed, emphasizing that no batteries, even lower than 9V, should be used. Matthieu Dubarry, an electrochemist at the Hawaii Natural Energy Institute who is an expert in batteries, told DailyMail. There is also an internal battery that can store energy if you don’t need it right away. Then cut open the USB end of your charging cord, connect the wires to the ends of the copper wires in the fruit circuit, and plug in your phone. If you attempt this for too long and the battery gets too hot, the phone can explode. This is a somewhat affordable option that ads more versatility than the traditional backup battery packs because it doesn't require electricity to charge in the first place. '5 or 6 [phone batteries] is as much power as a hand grenade,' he said. After reconnecting again and giving the iPhone another 15 minutes to charge, it was at only 9 percent battery - less than it started with. The phone started out at 13 percent - after 15 minutes using the DIY charger it was still at 13 percent. Next, connect one end of the pen spring to the other sprocket, and then connect the spring's other end to the metal piece on the side of the car charger. Using this small, 10. 1-ounce device, you can charge your phone using solar power. com that trying to charge a phone with a 9V battery 'is certainly not a good idea because of the voltage. Then connect your charging cable to the phone and USB port of the car charger as you usually would. Battery packs are the easiest and safest way to charge your phone. The inventors claim that when fully-charged, the turbine can charge your phone four to six times. A video showing how to make a charger with a 9V battery went viral on Twitter today before being removed from the site. Simply spread out the panels facing the sun to the charge the device itself (which should take about 10 hours), and then you can charge your phone. To assemble it, connect the metal point on the car charger adapter to one sprocket on the battery. You can charge these devices ahead of time when you do have power and then use them to charge your phone (as well as other devices) later when you can't reach an outlet or don't have electricity. Two electricians designed the world’s first portable turbine phone charger that lets people charge their mobile phone using wind power alone. com this method works on paper but is unlikely to charge your phone very much at all and can also damage it. . 'It's possible, but food is better for eating than charging a phone,' he said. The parts needed to make this charger are a 9V battery, a spring from a pen, a car charger adapter, and a phone. 'There’s a risk, and we don't want people getting hurt because they tried something off the internet without knowing about it. '. He explained the iPhone probably has a safety that prevents it from accepting the charge from the 9V battery, which... From battery packs, solar panels and hand cracks to DIY chargers using a 9v batteries, there are dozens of way to charge your phone without using a typical charger. How to charge your phone if the power goes out (and why you SHOULDN'T use the 'battery hack' taking Twitter by storm) The viral method of using a 9V battery and car charger proved to be a flop Experts say method sweeping Twitter could permanently...

Nissan Unveils Redesigned 2018 Nissan LEAF With 240–400 km Range & ProPilot Autonomous Driving Features - CleanTechnica

Customers will immediately appreciate the signature vibrant blue stitching, an emblem of Nissan EVs, in the seats, door trim, armrest and steering wheel. With that in mind, expect to see ProPILOT making its way into other Nissan vehicles. The new LEAF goes on sale Oct. If traffic restarts, the car will resume driving when the driver touches the switch again or lightly presses the accelerator to activate ProPILOT. The center display has a screen with a flush-surface design allowing the driver to easily operate audio and navigation systems and connect to smartphones intuitively with just a fingertip. This new and ergonomic center console design gives easier access to the controls and switchgear in the lower portion. The combination of these two technologies will make freeway driving much less stressful as the driver hands over control to ProPILOT. The new LEAF is also available in a two-tone White/Black. In performance and agility, the new LEAF excels. To match the improved output of the electric motor and inverter, Nissan engineers enhanced the car’s chassis for better stability. Source: 2018 Nissan Leaf Press Kit. The display shows the Safety Shield technology, the vehicle’s state-of-charge and a power gauge, as well as audio and navigation system information. 2018 Nissan LEAF specifications (U. S model). This is thanks to a software upgrade, new control logic working in conjunction with the steering angle sensor, and a 10 percent increase in steering torsion bar stiffness. Update: This article has been updated to clarify that the 400 km range Nissan mentioned is apparently on the Japanese testing system, which probably means something closer to 240–300 km (150–190 miles) in the real world. By simply releasing the accelerator, the LEAF will come to a smooth and complete stop without the need to press the brake pedal. Another innovation that enhances the LEAF’s driving experience is the e-Pedal, which is offered as standard equipment on all grade levels. It is almost as if the first-generation LEAF went away for a boot camp for the summer and has only now taken off the wraps to reveal its new hardbody. The new LEAF’s improved acceleration will boost enjoyment even further. A spoiler integrated in the window graphics gives the new LEAF an impressive, sporty look. When the car is activated, a start-up movie is displayed, giving the driver a sense of excitement about driving an electric car. The nose of the new LEAF is striking and aggressive, sharpening up the round, bubbly curves that defined the first generation and tightening up the edges. Nissan pushed beyond mere intelligent cruise control with the ability to actually steer the vehicle, keeping it centered in the lane. The Tesla Model 3 has an EPA rating of 220 miles of range and the Chevrolet Bolt has an EPA rating of 238 miles of range. The new LEAF’s cabin features roominess and openness with the brand’s “Gliding Wing” design language used as a framework. If the car in front stops, the ProPILOT Assist system will automatically apply the brakes to bring the vehicle to a full stop if necessary. The new LEAF’s palette of colors offers customers a wide range of options according to their tastes. Scroll down for the full specs on the new LEAF as well as the full text of the press release. Owners can also access their smartphone to check the car’s battery status. It allows the driver the simplicity of accelerating, decelerating and stopping the car by using the accelerator pedal alone — a revolutionary innovation that can change the way people drive. In some countries with V2G (vehicle-to-grid) systems, LEAF owners can get incentives from energy companies to improve power grid stability by absorbing demand fluctuation. With a deceleration rate of up to 0. 2g, the e-Pedal eliminates the need for drivers to constantly move their foot from the accelerator to the brake pedal to slow down or stop. Looking to the future, the LEAF sets a very high bar for other automotive manufacturers looking to compete in the $30,000 electric vehicle market. I personally like the look of the first-generation LEAF, but at the same time prefer EVs with more mainstream appeal simply because they are more likely to be adopted by mainstream consumers. The customer can also recharge the battery in the middle of the night, when prices are lowest in some markets, and then use the electricity during the day to reduce energy costs. The comfort and quietness of the new Nissan LEAF deliver a peerless ride. Even at highway speeds, the new Nissan LEAF’s cabin stays very quiet. While the energy capacity of the lithium-ion battery pack has been significantly increased, the cabin’s interior dimensions remain essentially unchanged and comfortably accommodate five people. Nissan believes that its intelligent implementation of this system will allow drivers to perform more than 90% of driving with just one pedal. Even with the additional power output, the new LEAF’s driving range has been increased. The new e-powertrain delivers an exhilarating, linear driving performance with a power output of 147 horsepower, 38 percent more than the previous-generation LEAF. Using NissanConnect, a key part of Nissan Intelligent Integration, the driver can search for continuously updated information such as the location and operating hours of free charging stations and charging station availability. For those who want more excitement and performance, Nissan will also offer a new higher power, longer range version at a higher price for the 2019 model year. Studies by Nissan in Japan, Europe and the U. S. have shown that the LEAF’s e-Pedal reduces the number of times the driver must apply the brakes while commuting in heavily congested traffic. [ Edit: Presuming the 400 km estimate is on the Japanese system, the EPA rating should be considerably lower, likely even putting the figure below the base Model 3. But we have to wait for the EPA rating to confirm how much different the rating... The battery pack occupies the exact same dimensions as that of the previous-generation LEAF. The new LEAF’s electric power steering system has a more linear feel that enhances confidence, especially on highways, with enhanced feedback from the road surface. Heavy components, including the battery, are placed in the center of the body, helping achieve smaller yaw moments of inertia compared with front-engine vehicles and thereby improving directional stability, enabling smoother cornering. Thanks to the aerodynamic body styling, including a rear bumper with a clear-cut curve and aero-design wheels, the new Nissan LEAF has a 0. 28 coefficient of drag. The new battery design adds energy-storage capacity without increasing the size. The new LEAF’s design expresses Nissan’s forward-thinking attitude and its pioneering approach to replacing the world’s best-selling electric vehicle. Through the thoughtful design of the center console and switchgear, the new LEAF gives drivers the information they need where they need it. This helps them focus on what really matters the most – an enjoyable drive. ProPILOT also includes many other active safety features, like: Intelligent Lane Intervention, Lane Departure Warning, Intelligent Emergency Braking, Blind Spot Warning, Rear Cross Traffic Alert, and Intelligent Around View Monitor with moving... The individual cell structure of the laminated lithium-ion battery cells has been improved, representing a 67 percent increase in energy density versus the original 2010 LEAF model. While the conventional brake pedal must still be used in aggressive braking situations, the e-Pedal lets drivers use a single pedal for more than 90 percent of their driving needs. That will not break any speed records and likely still feels slow to mainstream consumers, but it shows that it’s possible to keep quick charge times down as 200+ mile EVs drive battery sizes higher and higher. If the driver in front of the vehicle slows down quickly, ProPILOT will accordingly decrease the speed of the vehicle to maintain a preset buffer distance (or time), set by the driver. The new LEAF also comes with Intelligent Ride Control for more precise electric motor torque control generation when cornering, reducing vibration while simultaneously improving ride quality and steering control. As it is not a fully autonomous driving solution, the driver will be required to maintain a presence in the driver’s seat and ready to takeover for the system, but it represents a step change improvement compared to other Nissan vehicles. Ergonomic testing by Nissan shows that this new 45-degree angle allows drivers of all heights to easily and comfortably connect the charger. e-Pedal allows a driver to use the accelerator pedal to accelerate as normal by depressing the pedal, but it changes the behavior of the pedal as it is released, gradually applying a stiff regenerative effect to slow the vehicle as if it were... ProPILOT Assist is Nissan’s implementation of one of my favorite autonomous driving technologies — Traffic Aware Cruise Control (TACC) — which allows the driver to set the cruise control speed and adjusts dynamically to traffic conditions as they... This allows for a new stowage area at the base of the center console – ideal for a smartphone or wallet – as well as an easily accessible power switch, a 12-volt power outlet and a USB port. Following the event, Nissan launched the official 2018 Nissan LEAF website to lure the thousands viewing the livestream in with all the juicy details. A newly designed interface on the Nissan LEAF smartphone app allows users to monitor the vehicle’s state of charge, schedule charging to benefit from optimal energy tariffs, find the nearest charging station, and pre-heat or cool the car before... The focal point of Nissan Intelligent Power in the new LEAF is the e-powertrain, which offers improved energy efficiency and increased torque and power output. ProPILOT can bring the vehicle to a complete stop and resume driving without any input from the driver for an experience that should drastically reduce the strain on drivers during stop-and-go driving. The car’s new lithium-ion battery pack delivers an estimated range of 150 miles , which should satisfy the daily driving needs of the majority of LEAF owners. For that reason, I am thoroughly satisfied that Nissan went back to the drawing board with the redesign of the 2018 Nissan LEAF, which has a much more mainstream look to it while still holding onto some of the fun design cues of the original. The signature V-Motion grille, the boomerang light signature and the floating roof emphasize the presence of Nissan brand design, giving the LEAF an appearance similar to other Nissan models, such as the popular Rogue. The new LEAF links drivers, vehicles and communities through the user-friendly NissanConnectSM feature and systems that share power between electric vehicles and homes, buildings and power grids. That battery is able to be refilled at an impressive rate as well, with a 40 minute charge time from the built-in low battery alert back to an 80% charge. The high, awkward, first-generation LEAF has had its top chopped, leaving behind a lower, sportier LEAF that carries forward some of the design elements from the Nissan IDS Concept without similarly alienating consumers by going full-bore modern. Another key engineering improvement for the lithium-ion battery pack is the use of enhanced electrode materials with revised chemistry, resulting in higher power density while contributing to greater battery durability upon charge and discharge. This impressive feat is a testament to Nissan’s expertise in electric powertrains, especially when considering that Nissan made the powertrain even more powerful with a new 147 horsepower | 236 lb-ft torque electric motor. Chevy is surely not excited about the news, as the base price of the new LEAF undercuts the base price of the Chevy Bolt by a staggering $7,500 while offering autonomous driving features that simply aren’t available in the Bolt. Using vehicle-to-home systems, the battery makes it possible to store surplus solar power during the daytime and then use it to help power the home in the evening. Along with ProPILOT Assist and e-Pedal, the new LEAF is equipped with a set of advanced safety technologies including Intelligent Lane Intervention, Lane Departure Warning, Intelligent Emergency Braking, Blind Spot Warning, Rear Cross Traffic... Offering these step change improvements at a price point under $30,000 USD makes the new LEAF extremely competitive compared to its peer group and feels like a great spot compared to the new Tesla Model 3 as a lower-priced alternative with more... A clear-blue 3D mesh pattern with a “freezing” motif, on a flush surface inside the V-Motion grille, expresses the LEAF’s uniqueness as an EV. The new LEAF’s projector-beam headlights with dual, direct-lens low and high beams are a first for Nissan. The new, zero-emission Nissan LEAF embodies Nissan Intelligent Mobility, the company’s approach to changing the way cars are driven, powered and integrated into society. Headlining the new LEAF’s Nissan Intelligent Driving technology are ProPILOT™ Assist , e-Pedal and the company’s heralded Nissan Safety Shield. Drivers will feel more confident, excited and connected thanks to the new Nissan LEAF’s ProPILOT™ Assist driver assistance technology, e-Pedal, increased power and range, and improved refinement, comfort and convenience. “The new Nissan LEAF, with its improved autonomy range, combined with the evolution of autonomous drive technology, such as ProPILOT Assist and the simple operation of the e-Pedal, strengthens Nissan’s EV leadership, as well as the expansion of... The longer range on the new 2018 Nissan LEAF — nearly triple that of the first-generation 85 mile LEAF — was done without tripling the capacity of the battery. Autonomous Driving Features Nissan didn’t stop there with the new LEAF but instead took on the competition head on with the intentional inclusion of the Nissan ProPILOT Assist solution that brings along a smattering of autonomous driving... Summary Overall, the new LEAF is a game changer for Nissan, with nearly 3 times the range of the first-generation LEAF, a more mainstream design that is sure to appeal to a larger segment of consumers, and autonomous driving technologies that will... “The new Nissan LEAF drives Nissan Intelligent Mobility, which is the core brand strategy for Nissan’s future,” said Hiroto Saikawa, president and chief executive officer of Nissan. Single Pedal Driving with e-Pedal When ProPILOT can’t be activated, Nissan has designed its new e-Pedal system to make single-pedal driving a reality in the new LEAF. Nissan just unveiled its new 2018 Nissan LEAF, which features a completely new exterior design that is sure to be less polarizing and more in line with the look and feel of the rest of the Nissan fleet. What’s more, Nissan brought all of this new technology and efficiency into the new 2018 LEAF while keeping the MSRP under $30,000. Mainstream Vehicle Design Anyone who has driven the first generation Nissan LEAF knows the looks others give the car. The additional details highlight just how much Nissan has done to round off the edges on the first-generation LEAF that made it a less attractive option for mainstream consumers, while also adding exciting new autonomous vehicle technology to... The three key aspects of Nissan Intelligent Mobility exemplified by the new Nissan LEAF are Nissan Intelligent Driving, Nissan Intelligent Power and Nissan Intelligent Integration. Greater range and advanced technologies make new LEAF the ultimate electric vehicle 2018 LEAF offers a longer range at a lower price – with stronger performance, striking new design and cutting-edge technologies Since its launch in 2010, LEAF has...

For US Grid Markets, an Eclipse Day Is Like Any Other Day for Managing Solar Power - Greentech Media

That doesn’t mean that the price for megawatts on the energy markets run by grid operators remained stable through the event, though. Here's a chart from Blake Shaffer, a former energy trader and economics doctoral candidate at the University of Calgary, showing the 5-minute shifts in prices per megawatt-hour during the day of the eclipse. But California can see similar swings in solar from the burn-off of coastal fog in mid- to late morning, or from the wind and clouds coming in from the Pacific. But that demand actually tracks pretty well, though not perfectly, with the bell curve of solar PV power production -- assuming the hottest days are also sunny, which they almost always are in California. But while PJM had expected to see an increase in electric demand on the grid, it ended up seeing a net decrease of about 5,000 megawatts through the eclipse -- a shift it attributed to “reduced air conditioning, increased cloud cover and changes... California had two-thirds of the 9,000 megawatts of U. S. solar power that was shaded out by the passage of the moon between us and the sun, giving the rest of the country’s grid operators less to worry about. But with an effect that’s even more predictable than the weather, grid operators across the country were able to manage their way through multi-gigawatt dips in solar generation without any worries about keeping the grid itself stable. But this kind of day-by-day swing in solar -- and wind, and hydro -- isn’t unusual for CAISO. That’s when California sees the “duck curve” emerge, with excess solar driving demand down through midday (the “belly” of the duck) then fading away in the afternoon, creating a steep ramp in demand (the “neck” of the duck). It will also bring together the solar expertise of GTM Research, the wind energy analysis of MAKE, and the broader energy and utilities expertise of Wood Mackenzie, for an end-to-end view across the entire energy market value chain. In North and South Carolina, where the shadow of the eclipse ended its transcontinental track, Duke Energy lost about 1,700 megawatts of its 2,500 megawatts of solar, a similarly small portion of its overall load. In California, solar production fell off a cliff, dropping about 3,500 megawatts from 9 a. m. to 10:30 a. m. -- and the price of energy spiked from about $25 to more than $50 per megawatt-hour. Then, as the eclipse passed and solar power returned, the surge of energy coming onto the grid pushed prices down past their starting point, and then into negative territory -- forcing generators to pay the market to take their excess power, and... This behavior includes people turning off lights, unplugging appliances and taking other energy-saving measures, either on their own or in response to eclipse-themed marketing and promotional efforts, like California’s media blast asking people to... The solar eclipse that crossed the United States on Monday may have cast its shadow over large swaths of solar PV from California to South Carolina. For the eclipse, CAISO prepared for a drop-off of 70 megawatts per minute, and a ramp-up of about 100 megawatts per minute, compared to a typical 29 megawatts-per-minute ramp between 9 a. m. and noon. Where solar and demand really get out of whack is on sunny but cool spring days, when there’s not enough air conditioning, or any other loads, to suck up the rising tide of solar power. Texas grid operator ERCOT , for example, was expecting solar generation to drop by about 600 megawatts through the eclipse -- less than half of the 1,000 to 2,000-megawatt solar deficit it regularly handles on heavily cloudy days. Solar makes up less than 1 percent of the generation mix for mid-Atlantic grid operator PJM, which reported a drop of about 520 megawatts of wholesale solar generation from pre-eclipse to its peak, along with another loss of about 1,700 megawatts...
