In this edition of the clean energy and transport news roundup, we’ve got stories about Colorado solar fees, sheep as solar workers, solar microgrids, a new integrated energy storage system, driverless car insurance policies, a 2500 mile EV roadtrip, automatic braking systems, Musk’s pessimism about slowing climate change, Chinese EV startups, and more. [CleanTechnica isn’t the only Important Media site to cover clean energy & transport news, and if you’re looking for more stories on electric mobility, bicycles, solar and wind energy, and other related issues, we’ve got them at sites such as Solar Love, CleanTechies, Planetsave, Bikocity, Gas2, and EV Obsession. We also host a large cleantech group on LinkedIn, called CleanTechies Around The World.] In Colorado, XCel Energy proposed a new charge on all solar customers, an idea that was furiously resisted by a dozen or more solar power advocacy groups. Now, all parties have agreed to a negotiated settlement of the dispute that may serve as a model for other states. The agreement involves refocusing the pricing of electricity for retail customers on a time of day model. Not every solar energy installation goes on top of a roof. Utility scale systems, community solar, and some residential systems often are mounted on the ground rather than up in the air. What many of the owners of such systems tend to forget is that steps need to be taken to control the vegetation that will inevitably start to grow up underneath and around the panels as soon as the project is completed. The plan was to install 200 solar panels, seven Tesla Powerwalls, several SolarEdge inverters, along with installing lights and plugs for dozens of buildings. In order to complete the project on time, they hired and trained local electricians and construction crews. After three weeks in Virunga, all three solar micro grids were successfully installed. Now the park rangers have reliable lighting, communication systems, computers, radios, and GPS units. That means they no longer need to risk their lives to bring in diesel fuel and can more effectively protect the park and its denizens from thieves and poachers. SimpliPhi Power technology utilizes patented, licensed lithium ferrous phosphate cells with state-of-the-art proprietary management boards, circuitry, cell architecture and methods of assembly to create safe, intelligen,t and energy dense storage and management systems. SimpliPhi batteries feature the highest efficiency rate in the industry (98 percent), 10,000 cycle life and 100 percent depth of discharge. The compact, lightweight form factor does not require ventilation or cooling, is rated for outdoor installation, and can operate at a wide temperature range of -4 to 140 degrees Fahrenheit. Alyssa Craft and Jesse Stafford completed a cheap off-grid cabin-add-on to the trailer they are living in while setting up their homestead in the Western US. The cabin was built to allow them to heat the air around the trailer and prevent the plumbing, and themselves, from freezing during the snowy winter months. Sri Lanka looks to 70% renewables by 2030: The ‘Battle for Solar energy’ program aims to encourage the small consumers to install solar panels at their roof-tops and consumers will be paid for any excess energy exported to the grid. With this new program, government expects that at least 20% of the consumers produce electricity on their own. India wind energy policy has developers apprehensive about country’s first wind energy auction: Project developers are apprehensive about India’s latest wind energy policy which calls for large-scale auction of projects. The uncertainty amongst wind energy project developers in India originates from the fact that there is lack of clarity on the extension of crucial incentives like the accelerated depreciation and generation-based incentive. These two support mechanisms have been the sole driver of wind energy expansion in India. Indonesia could see 19% returns on solar Feed-in Tariffs: Indonesia may soon become a budding solar power market as feed-in tariffs recently announced by the government are expected to yield very attractive returns for developers. The Minister for Energy in the southern state of Karnataka recently told media outlets that construction on a proposed 5 GW solar power park will begin soon. The Pavagada solar power park is among the more than two dozen solar power parks with cumulative capacity of almost 20 GW approved by the Ministry of New & Renewable Energy. According to media reports, the Airports Authority of India (AAI) has installed solar power panels on the cargo complex of the Chennai airport. The solar power system is believed to have installed capacity of 5 MW and will generate enough electricity to meet 80% of the cargo terminal’s power demand. Engie subsidiaries will develop 400 MW of solar in Chile: Engie Energia Chile and Solairedirect, subsidiaries of French utility Engie, have announced plans to jointly develop 400 MW of solar power in Chile. South Africa could have 5.6 GW of wind capacity by 2020: The research and consulting firm GlobalData report states that more than 3 GW wind energy is expected to be installed by 2020 which will bring country’s cumulative wind capacity to 5.6 GW. The company apparently intends for the launch of the new insurance policy to move forward “the discussion around who or what is liable in the event of a collision.” The policy was designed “for people who may have driverless or autonomous features in their existing car, or who may be thinking of buying a new car with driverless or autopilot features such as Tesla’s forthcoming Model 3.” The trip — which has been dubbed Route 57 — involved 2,500 miles of travel through England, Wales, Scotland, and Ireland; through various scenic towns, national parks, cities, etc. The trip was blogged about in great detail by the driver, Jess Shanahan. Orange EV taking orders for its new T-Series all-electric terminal truck: The new T-Series electric terminal trucks build on the company’s initial T-Series trucks (capable of up to 24 hours of operation per charge), which have now been deployed at various sites in the manufacturing, shipping, retail distribution, warehouse, railroad inter-modal, and waste management industries. And buyers could qualify for up to $120,000 in incentives: Orange EV has announced that organizations and businesses operating fleets in California will now be able to receive up to $120,000 in incentives towards the purchase of new T-Series all-electric Class 8 terminal trucks with extended-duty battery packs. Tom Moloughney is an avid electric car advocate. Two years ago, he purchased a BMW i3 with the 0.65 liter onboard two cylinder range extender gasoline engine. 27 months later, he has 56,000 miles on the odometer. He says 96% of those miles have been done on electric power alone. He has purchased about 50 gallons of gasoline for the car, which works out to be more than 1,000 miles per gallon. Mercedes will market its EVs under the EQ brand: No self respecting premium auto company would dive into the deep end of the electric car pool without dreaming up some snazzy new title to define its EV brand. BMW started it with its “i” division. Audi followed along with its E-Tron models. Now Mercedes has all but confirmed that it will market its electric cars under the EQ brand. 90% of Chinese EV startups could be wiped out: Soon, entrepreneurs will need a license from the government to become an automobile manufacturer. (Existing companies like SAIC and BYD will not need to apply for licenses.) According to reports, no more than 10 licenses will be issued — a very small number for such a large country. “There are too many entrants in the sector, and some of them are just speculators,” said Yin Chengliang, a professor at Shanghai Jiao Tong University’s Institute of Automotive Engineering. “The government has to raise the threshold. It’s bad to see irrational investments in projects with low technology levels.” The summer doldrums are almost over and the world of automobiles is about to get re-energized as the new auto show season kicks off in Paris in September. Citroen has gotten the buzz started early by showing off its latest creation, the CXperience large sedan concept. Sadly, it looks at though the Citroen design team has been heavily influenced by the new Toyota Prius. That is not meant as a compliment. Speaking with MSNBC host Chris Hayes recently. Elon Musk said he is pessimistic about slowing or reversing the effects of carbon pollution on global climate change. Doing so will require an effective means of pricing carbon emissions agreed to and implemented by all nations, he told Hayes. In his remarks, Musk made reference to what economists call The Tragedy of the Commons. There are two kinds of automatic braking systems — one designed to avoid forward collisions and one that only tries to minimize the damage from one. Which is which? How do you know which system your car is fitted with? And what are you, the driver, supposed to do — or not do — if the car ahead stops short suddenly or a pedestrian steps into your path?   Drive an electric car?

The total electron content (TEC) measurements from a network of GPS receivers were analyzed to investigate the storm time spatial response of ionosphere over the Indian longitude sector. The GPS receivers from the GPS Aided Geo Augmented Navigation (GAGAN) network which are uniquely located around the ∼77 E longitude are used in the present study so as to get the complete latitudinal coverage from the magnetic equator to low mid-latitude region. We have selected the most intense storms but of moderate intensity (-100 nT < Dst < -50 nT) which occurred during the unusually extremely low solar activity conditions in 2007-2009. Though the storms are of moderate intensity, their effects on equatorial to low mid-latitude ionosphere are found to be very severe as TEC deviations are more than 100% during all the storms studied. Interesting results in terms of spatial distribution of positive/negative effects during the main/early recovery phase of storms are noticed. The maximum effect was observed at crest region during two storms whereas another two storms had maximum effect near the low mid-latitude region. The associated mechanisms like equatorial electrodynamics and neutral dynamics are segregated and explained using the TIMED/GUVI and EEJ data during these storms. The TEC maps are generated to investigate the storm time development/inhibition of equatorial ionization anomaly (EIA). © 2013 COSPAR. Published by Elsevier Ltd. All rights reserved.

The global wave number 4 structure in the Indian longitudinal region spanning from ∼70 to 95°E forming the upward slope of the peak in the total electron content (TEC) are reported along the crest of equatorial ionization anomaly (EIA). The continuous and simultaneous measurements from five GPS stations of GPS Aided Geo Augmented Navigation (GAGAN) network are used in this study. The long-term database (2004-2012) is utilized for examining the local time, seasonal, and solar cycle dependency on the longitudinal variations of TEC. Our results confirm the existence of longitudinal variations of TEC in accordance with wave number 4 longitudinal structure including its strength. The results suggest that these variations, in general, start to develop at ∼09 LT, achieve maximum strength at 12-15 LT, and decay thereafter, the decay rate depending on the season. They are more pronounced in equinoctial season followed by summer and winter. The longitudinal variations persist beyond midnight in equinox seasons, whereas in winter, they are conspicuously absent. Interestingly, they also exhibit significant solar cycle dependence in the solstices, whereas in the equinoxes, they are independent of solar activity. The comparison of crest-to-trough ratio (CTR) in the eastern (92°E) and western (72°E) extreme longitudes reveals higher CTR on the eastern side than over the western extreme, suggesting the role of nonmigrating tides in modulating the ExB vertical drift and the consequential EIA crest formation. Key Points Longitudinal variations of low latitude ionosphere over India are studied Longitude gradient of TEC is computed to quantify its strength Local time, seasonal, and solar cycle dependency is observed ©2013.

The commercial airport of Chennai will also be partly opened on Saturday after being shut for the past three days, which should help move workers and relief materials badly needed in the city of six million. Flood waters that had started to recede began rising again around noon after a new cloudburst that sent residents running for shelter under trees and in shopfronts. Parts of the flat, coastal city remained under as much as eight feet (2.5 meters) of water for a fourth day. Many residents have spent days stranded on rooftops since more than 345 mm (14 inches) of rain fell over 24 hours on Dec. 1, the most since the British ruled the city in Tamil Nadu state, then known as Madras, 100 years ago. India's fourth-largest city, Chennai has boomed in the 21st century as a center for vehicle factories and IT outsourcing. But trash-filled drains and building on lake beds in the rush to industrialization and prosperity has made it more prone to flooding. Despite combined rescue efforts by the military and civilian emergency services, help has yet to reach many areas. Residents were angered by reports that authorities had released water from brimming lakes without much warning. In one of the most shocking incidents, 18 patients in the intensive care unit of the MIOT International hospital have died since Wednesday, Health Secretary J. Radhakrishnan said, after floods took out generators running life-support systems. An enquiry will be conducted into the tragedy, he said. Military helicopters dropped food to residents stranded on rooftops and the defense ministry doubled to 4,000 the number of soldiers deployed to help the rescue effort. Facing criticism for its handling of the crisis, a battery of senior Tamil Nadu officials defended the government at a press conference at the state's water-logged headquarters on Friday evening. They said authorities have so far evacuated 127,580 people. More than half of them from banks of rivers are now sheltered in relief camps and are being treated for fever and infections to prevent an epidemic. V. Raghunathan, 60, a manager at an interior design company living in southern Chennai, complained about the lack of warning before flood gates were opened on some of Chennai's 30 waterways. "The authorities didn't give us adequate information about water being released from a nearby lake. Before we could take action my car had sunk and I had to move to the first floor of my apartment." The Tamil Nadu public works department said it did issue warnings, but the information apparently did not reach the public because of a breakdown in media and phone communications. The Chennai edition of The Hindu newspaper did not go to press on Thursday, apparently for the first time in 137 years. The government restored some commercial flights to a naval air base near the city, and the Airports Authority of India said the Chennai airport would be open for day-time operations for relief flights. Car factories that export around the world, however, stayed shut. Affected carmakers such as Renault, Nissan Motor Hyundai Motor and component maker Apollo Tyres will decide on Saturday whether to resume production. BMW will keep a plant closed until Dec. 7. A steadily rising number of families sought safety on the city's Basion Bridge flyover, many of them slum dwellers whose homes had been washed away. They sat in the open, carrying little bundles of prized possessions - soiled rupee notes and identity cards. A small van that arrived at the top of the flyover bearing water packets and biscuits was immediately overrun by people desperate for relief. Rajarwadi, who sold vegetables by the roadside, managed to grab a packet of biscuits for her daughter. She hadn't seen any government officials helping people camped out on the busy flyover on Thursday even though it was in the middle of the city. Jose Sebastian, the head of a local construction company, said the biggest worry for his volunteer group was areas where the water level was too high for them to deliver food. "We feel rather helpless," he said. "We have lots of food, we have volunteers ready to go, but we don't have the boats."

The Plug-in Electric Vehicles (PEVs) are the Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs). PEVs will dominate the transportation in the personal mobility mode and in the automobile market by 2030. Widespread adoption of PEVs brings potential, social and economic benefits. The focus on promoting use of electric vehicles in road transportation is very essential to meet the climate change targets and manage the ever hiking prices of fast depleting fossil fuels. However, there are lots of uncertainties in the market about the acceptability of PEVs by customers due to the capital and operation costs and inadequate infrastructure for charging systems. The penetration level in the market is not encouraging, in spite of incentives offered by Governments. Manufacturers are also not sure of the market, even though predictions are strong and attractive. Major manufacturers, however, are already ready with their plans to introduce electric vehicles to mass market. The use of PEVs has both technological and market issues and impacts. Series of research works have been reported to address the issues related to technologies and its impacts on political, economic, environmental, infrastructural and market potential aspects. Works dealing with suitable infrastructure such as charging stations and use of smart grids are reported. These steps are aimed to bring down the capital and operational costs that are comparable to the costing of conventional transport vehicles. The penetration level of PEVs in transportation will accordingly increase and keep the climate targets met and conserve fossil fuels for use in other economic segments. An overview on these issues is presented in this chapter. © 2015 Springer Science+Business Media Singapore.

An annular solar eclipse occurred over the Indian subcontinent during the afternoon hours of January 15, 2010. This event was unique in the sense that solar activity was minimum and the eclipse period coincides with the peak ionization time at the Indian equatorial and low latitudes. The number of GPS receivers situated along the path of solar eclipse were used to investigate the response of total electron content (TEC) under the influence of this solar eclipse. These GPS receivers are part of the Indian Satellite Based Augmentation System (SBAS) named as 'GAGAN' (GPS Aided Geo Augmented Navigation) program. The eight GPS stations located over the wide range of longitudes allows us to differentiate between the various factors induced due to solar eclipse over the equatorial and low latitude ionosphere. The effect of the eclipse was detected in diurnal variations of TEC at all the stations along the eclipse path. The solar eclipse has altered the ionospheric behavior along its path by inducing atmospheric gravity waves, localized counter-electrojet and attenuation of solar radiation intensity. These three factors primarily control the production, loss and transport of plasma over the equatorial and low latitudes. The localized counter-electrojet had inhibited the equatorial ionization anomaly (EIA) in the longitude belt of 72°E-85°E. Thus, there was a negative deviation of the order of 20-40% at the equatorial anomaly stations lying in this 'inhibited EIA region'. The negative deviation of only 10-20% is observed for the stations lying outside the 'inhibited EIA region'. The pre-eclipse effect in the form of early morning enhancement of TEC associated with atmospheric gravity waves was also observed during this solar eclipse. More clear and distinctive spatial and temporal variations of TEC were detected along the individual satellite passes. It is also observed that TEC starts responding to the eclipse after 30 min from start of eclipse and the delay of the maximum TEC deviation from normal trend with respect to the maximum phase of the eclipse was close to one hour in the solar eclipse path. © 2011 COSPAR.

The purpose of this paper is to describe the interfacing of 16-bit 1-MSPS CMOS ADC to FPGA based signal processing card. An on board real time digital signal processing system is designed using FPGA, the architecture and the state-of-the art of the Field Programmable Gate Arrays (FPGAs) make them especially suitable to act as interface between an high speed ADC and a data processing unit. The platform can decode process of various kinds of digital and analog signals simultaneously For the optimum performance a 16 bit 1 MSPS ADC is interfaced with FPGA to make all the data processing onboard in real time[1] The Virtex4-SX FPGAs offer designers a low cost and feature rich platform for interfacing with high speed Analog to Digital Converters (ADCs). Interfacing high speed ADCs can present several challenges to designers including: DDR to SDR Conversion, LVDS Buffers, Tight Timing Margins, and High Data Rates in FPGA[5].As the need for data bandwidth increases for end systems, data transmission rates continue to increase for Analog to Digital Converters (ADC) and the associated FPGA solution to interface to the ADCs and other parts of the system.AD7671 features a very high sampling rate mode (Warp) and, for asynchronous conversion rate applications, a fast mode (Normal) and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput[8]. It is fabricated using Analog Devices high-performance, 0.6 micron CMOS process, with correspondingly low cost. © 2011 IEEE.
