first_imgIndian Railways turns to solar to cut coal-fired electricity costs FacebookTwitterLinkedInEmailPrint分享PV Magazine:To reduce its annual electricity bill, Indian Railways will soon run trains powered by solar power from arrays of PV cells deployed along electrified tracks in 10 states. The solar power generated will replace 4 GW of coal-fired electricity consumed by the railways, saving the operator 20% of its annual energy bill in the first year and 40% thereafter. Indian Railways currently buys electricity for around INR5 ($0.07) per unit.Developers will recover the installation cost of solar panels and other equipment through the sale of power to the railway operator. Under an agreement with states, there will be a provision to sell surplus power to the local utilities, which will supply equivalent power when Indian Railways needs it.The railway board is examining a project bid document prepared by the Solar Energy Corporation of India which recommends PV electricity from panels be fed through inverters and step-up transformers directly into the 25 kV overhead traction system. That would eliminate the cost of laying separate transmission lines and boost manufacturing of 25 kV single-phase inverters.Around 20 manufacturers, including ABB, Huawei, Delta and Sungrow, are said to be interested in manufacturing the equipment given sufficient demand, according to the Times of India. “This is a historic step towards Indian Railways becoming a net zero emitter by 2030,” railways and coal minister Piyush Goyal told the daily newspaper. “Indian Railways is by far the greenest travel option for transportation.”The government of India is encouraging cash-rich public sector undertakings to set up renewable energy projects. Indian Railways has committed to developing 5 GW of solar by 2025.More: Indian Railways plans to tender 4 GW solar projectlast_img read more

Volleyball keeps bags packed

first_imgBRYAN FAUST/Herald photoAfter nearly a month of fine-tuning in early-season tournaments, the Wisconsin Badgers volleyball team is ready to tip off the real season with the start of conference play.Wisconsin will travel to the Land of Lincoln this weekend for a match against Illinois Friday and Northwestern Saturday as Big Ten action gets underway.The Badgers have stressed the need for improvement ever since opening the season at home with the AVCA Volleyball Showcase. After dropping a match to top-ranked Texas and squeaking by unranked teams in later tournaments, several key areas to develop were exposed, such as passing and defense.”I think we’ve definitely picked up our serving,” senior floor captain Maria Carlini said. “We’ve been working really hard on our defense as well and it shows. We’ve been outdigging teams that we haven’t in the past.”Head coach Pete Waite, on the other hand, is still looking for his team to get better in a different facet of the game — one that doesn’t involve skill so much as energy.”We’ve definitely improved since the AVCA Showcase, but there are still things we need to work on,” Waite said. “We need to try to push hard right away to get the jump on teams. This is a very good come-from-behind team, but it’s not a situation I’d like us to be in.”This weekend will provide the Badgers with a test to see where they are in their progression since the start of the year as both Illinois and Northwestern have drastically improved since last year.In 2005, the Fighting Illini and Wildcats finished in the middle of the conference at seventh and sixth, respectively. Despite being predicted to finish at just about the same spots, the two figure to be the conference dark horses.Illinois acquired two transfers in the off-season — outside hitters Stephanie Alde from Northwestern and Amy Palash from Valparaiso — something Waite believes makes the Illini a respectable team instantly.”Illinois has two transfers coming so they automatically have two veteran players stepping into their lineup that would’ve been holes with inexperienced players,” Waite said. “That alone makes them stronger already.”Illinois also has a very balanced team with two players hitting more than four kills per game — middle blocker Vikki Brown and outside hitter Kayani Turner.Freshman Ashley Edinger, ranked as the No. 1 incoming libero in the nation by PrepVolleyball.com, has stepped in for Illinois and provided the team with some much-needed defense, averaging 5.03 digs per game.The toughest part about traveling to Champaign, Ill., will undoubtedly be adjusting to Huff Hall. Its student section is one of the largest in the nation, as 1,682 students packed in for one of last weekend’s games, more than half of the 3,129 total fans in the arena. Furthermore, Huff Hall’s court is a tad bit shorter than most others so there is much less space to serve.”Their crowd has gotten stronger every year, so it’s a tough place to play,” Waite said.As for Northwestern, the Wildcats are coming off an upset win over then-No. 24 Arizona at home, going on to win its Wildcat Classic last weekend in dramatic five-game fashion. NU is undefeated at home so far this season.”Northwestern definitely has improved from last year,” UW outside hitter Audra Jeffers said. “They’re doing a lot more out of the back row with three hitters out of the back, so that’s going to be huge with our blocking.”We’re really going to have to seal up the block across the net, get all three blockers in to stop that.”Defensively, Northwestern is somewhat similar to Illinois.”Both Illinois and Northwestern are really good defensive teams,” said Carlini. “The main thing with those teams is they’re really scrappy, they play great defense so we need to outdig them.”Either way, starting the Big Ten season out on the road will be difficult, but the Badgers are used to traveling lately. After opening the season at home with the AVCA Volleyball Showcase and the following InnTowner Invitational, Wisconsin has been away from the Field House ever since, going as far as San Diego last weekend.”You’ve got to start somewhere,” Waite said. “We’ve been on the road the last two weekends so this will be three in a row for us, and in ways I think we’re prepared for it because we’re just packing up the suitcases again and hitting the road. We’re ready to go.”last_img read more

Humble Indie Bundle adds 5 more games

first_imgThe 3rd iteration of the charity-friendly Humble Indie Bundle has been doing swift business over the past few weeks. Revenue from the offer of 5 games plus access to Minecraft for a couple of weeks is about to reach $1.5 million and 277,000 bundles sold. But the team behind it have had a new idea to boost revenue yet further for the last 5 days.If you purchase the bundle any time before August 9, and spend more than the average for the day, you will receive the Humble Indie Bundle 2 games as well. That means as well as gaining access to Cogs, VVVVVV, Hammerfight, and And Yet it Moves, you will also receive Braid, Cortex Command, Machinarium, Osmos, and Revenge of the Titans.Don’t forget the bonus game Steel Storm is also thrown in for free, and the access to Minecraft on offer too. It’s is a fantastic deal that also sees Child’s Play and the EFF benefit too depending on how you to decide to split the money you are spending between them and the developers.As we reported earlier in the week, Linux users are paying the most by far for the bundle. They were averaging $11.63 per purchase compared to $6.61 for Mac gamers and $3.80 for the Windows crowd. Those averages have now increased slightly to $11.80, $7.14, and $4.45, and will probably continue to do so at a faster rate as gamers spend a little more to get the extra games.Whichever way you look at it the bundle is still a bargain, and to get the extra five games today you only have to spend more than $5.38. With the average rising though, it’s sure to be higher tomorrow making the 10+ game bundle more expensive the longer you wait to buy.More at Humble Bundlelast_img read more
