Sprinters Usain Bolt and Shelly-Ann Fraser-Pryce were on Friday night presented with the 2015 RJR Sports Foundation National Sportsman and Sportswoman of the Year awards at the Jamaica Pegasus. Bolt was winning his sixth Sportsman of the Year award, after copping titles in 2008, 2009, 2011, 2012 and 2013, while Fraser-Pryce, who also won in 2012 and 2013, was winning her third Sportswoman of the year award. “I want to thank my fans, who supported me this season, I really needed it. I want to thank my coach, I put him through a lot of stress, he has stood by me this season … I want to thank God and I promise I will try to do my best this season,” said a grateful Bolt. Fraser-Pryce, who won gold medals in the 100m and 4x100m at last year’s World Championships in Beijing, China, as well as the Diamond League 100m title, was also presented with the Sagicor Iconic award. The sprinter has won two Olympic gold medals and seven at the World Championships level since her ‘arrival’ at the 2008 Olympic Games in Beijing. “Everything I have done is attributed to how much God has blessed me,” said Fraser-Pryce. “I am honoured to be here collecting this award a third time. I want to thank my coach for believing in me and putting up with me; and for me putting up with him sometimes.” Bolt’s award, which now puts him second in the all – time list behind boxer Michael McCallum (7) came after another dominant season by the powerful sprinter, who won three gold medals at the World Championships (100m, 200m and 4x100m). World Championships 100m hurdles gold medal winner Danielle Williams was the runner-up to the Sportswoman of the year, with shot put bronze medal winner O’Dayne Richards took home the male equivalent. The first award of the evening went to veteran quarter-miler and cancer survivor Novlene Williams-Mills, who was presented with the Chairman’s award. The People’s Choice Award for ‘Performance of the Year’ went to Jamaica’s senior women’s 4x400m relay team, which won gold at the World Championships, while former Netball Jamaica president Marva Bernard received the Lifetime Achievement Award.
Last week I suggested some ways to reduce your hot water use. This is almost always the easiest way to save energy with water heating—it’s the “low-hanging fruit” to be sure. Over the next few weeks, I’ll get into water heating options. To start, let’s look at the differences between “storage” and “tankless” water heaters.The vast majority of homes have storage-type water heaters. There’s an insulated tank and either a gas burner or electric heating element (often two elements) to heat the water. An advantage of storage water heaters is that you don’t need a very large gas burner or a really high electric current flow to heat the water. The gas burner or element can chug along for hours, gradually warming up water in the tank. The water remains “thermally stratified” so that water drawn off from the top is always the hottest and even after 90% of the hot water is used up, the delivered water is still at full temperature. Storage electric water heaters also allow “off-peak” electricity to be used—more about this in a future column.While storage water heaters are the most common, there’s a lot of interest in tankless models—sometimes referred to as “on-demand” or “instantaneous” water heaters. The advantage of these is that you don’t have water sitting all the time, losing energy through the tank walls. (Even with insulation, heat loss occurs.)As with storage water heaters, tankless models can be either gas-fired or electric. For very small loads, such as with a remote lavatory that has only a sink (with a low-flow aerator), an electric tankless water heater can make a lot of sense since it obviates the need for running a gas line. But for whole-house needs—where a central water heater serves one or more bathrooms with showers, the kitchen sink, dishwasher, and clothes washer—a gas-fired tankless water heater is almost always a better choice than electric.Providing enough electric current to instantaneously heat 4-5 gallons per minute (gpm), boosting the temperature more than 60 degrees F (as might be necessary if two showers are being used at the same time, or if a dishwasher or clothes washer is being used while someone is showering) would take a huge amount of electric current—on the order of 40 to 60 amps. Providing so much electricity would require special wiring and special circuit breakers, which are expensive. And from a big-picture standpoint, if a lot of people used these tankless electric water heaters, utility companies would have to build more power plants to have adequate electricity available during periods of time with high use of hot water, such as during the morning shower period. Utility companies love storage water heaters, because they spread out the demand.If you decide to go with a whole-house, gas-fired (natural gas or propane) tankless water heater, be aware that because the burners on tankless water heaters are so large—150,000 to 200,000 Btu/hour, vs. 40,000 Btu/hour for a typical gas-fired storage water heater—larger-diameter gas lines are required (usually 3/4-inch instead of 5/8-inch). And to burn that much gas, a lot of air flow is required, which necessitates a large flue, and there is potential for significant air leakage if not properly installed.Another issue with tankless gas water heaters is pilot vs. pilotless ignition. Tankless water heaters used to all have pilot lights, which burned gas all the time. The wasted energy from these pilot lights (about 5,000 Btu/hour) was about the same as the heat loss through the insulated walls of a storage water heater, so you didn’t end up with much energy savings.Most new tankless water heaters have electronic ignition, and if you’re thinking of a tankless water heater I’d go with this option. The gas burner is ignited using an electrical spark. With pilotless ignition, today’s gas-fired tankless water heaters offer the highest efficiency of any water heater, except heat-pump models, which I’ll cover in a future column.A few gas-fired tankless water heaters made by the Korean companies Takagi and Navien have “condensing technology” with an Energy Factor of up to 0.98 (Energy Factor is a measure of efficiency). Non-condensing, pilotless tankless water heaters have Energy Factors of .82 to .87, while conventional storage water heaters have energy factors of .58 to about .67 (up to .80 for condensing models).So which is better: a storage or a tankless water heater? Despite the potential for higher efficiency with tankless technology, it will surprise a lot of my readers to learn that I’m partial to storage water heaters for most situations. They are less expensive, less prone to mechanical problems, and, with electric models, offer the potential for using off-peak electricity—which is significantly less expensive than propane. Storage water heaters also encourage thrift when showering, since there’s a finite amount of hot water.

At a good conference, we get a chance to network with colleagues, to learn about recent research, to see new products, and to talk with manufacturers’ reps. I’ve had the good fortune, over the last six weeks, to attend three conferences focusing on green building and residential energy:It would be a daunting task to report on all of the excellent presentations I attended at these three conferences. While I hope to report in depth on some of the presentations in coming months, I’ve decided (as a stopgap measure) to share a collection of pithy quotes gleaned from all three conferences.Bill Rose is a research architect at the Building Research Council at the University of Illinois, and the author of the landmark textbook, Water in Buildings. At the Boston conference, Rose said, “If you do something to the building envelope to make the exterior colder, it will be wetter. Cold means wet; warm means dry. This pertains to materials outboard of the thermal envelope, primarily during cold weather. At a given vapor pressure, chilled materials are wetter than warmed materials. This is an equilibrium condition. It is not a consequence of diffusion, air leakage, or drying potential to one side or the other.”Carl Seville, the Green Building Curmudgeon, is a consultant based in Atlanta. At the Greenprints conference, Seville said, “The different green certification programs are essentially similar in concept. LEED has the most onerous documentation requirements. That’s job security for me. The 2012 version of the National Green Building Standard is based on the 2012 energy code, while LEED is still down at the Energy Star Version 2 level. USGBC is like a battleship that can’t turn very easily. Now it is the least difficult program to…
Barely hours after Bihar Chief Minister Nitish Kumar asked police officials to pull up their socks and not leave anything on bhagwan bharose (mercy of God), a police official late on Friday night was killed in an encounter with criminals in Khagaria district of the state.On a tip off Parsaha police inspector Ashish Kumar Singh led a team of policemen to arrest gangster Dinesh Muni in Salarpur riverine area of Khagaria district and engaged in encounter with them.The remote Salarpur riverine area is known to be a hiding place for notorious criminals in the state.Police had also got information that criminals of neighbouring Naugachhia district too had congregated at the place.The criminals started firing at policemen and a fierce encounter took place between them late on Friday night.A bullet hit Ashish Kumar Singh on his chest and he died on the spot. Another policeman too was injured in the encounter while a criminal too was shot and injured.Later, senior police officers including Meenu Kumari and Pramod Kumar Jha reached the spot with reinforcement. No criminal was arrested yet in the intensive combing operation launched by the policemen in the area.Known as a brave police officer, Ashish Kumar Singh, a 2009 batch Inspector, had survived a bullet injury after he was shot at during an encounter with local gangsters in the same area.Earlier in the day on Friday while inaugurating a new building for police headquarter, chief minister Nitish Kumar had asked police officials to pull up their socks and not to leave things bhagwan bharose (God’s mercy).“It is a fine structure which would help you to work efficiently…get your act together and spare some thoughts for keeping corruption and crime under control…do not leave things bhagwan bharose”, said Nitish Kumar.
From a rice mill clerk and a farmers’ leader to heading the first BJP government in the south, B.S. Yeddyurappa has been a master survivor emerging unscathed through much turbulence in his three years in office before the Lokayukta report on illegal mining scam did him in.Bookanakere Siddalingappa Yeddyurappa (68), who completed three years and two months in office as the first saffron party chief minister of Karnataka, ushered in a bumper harvest for the BJP in the state during the 2008 Assembly Elections.Always sporting his trademark white safari suit, he was also briefly the chief minister in November 2007 before the coalition government with JD(S) collapsed following what he called “betrayal” by its leader and his predecessor H D Kumaraswamy.Yeddyurappa, who had to juggle with one crisis or the other, has shown his skills as a political survivor, overcoming adversities emanating from within his own party and the combined Congress-JD(S) onslaught to oust him over alleged land scams.Learning initial steps of leadership, development of mass base and human resource management from the RSS, it has been a fascinating journey dotted with many struggles for the devout Lingayat who believed that the gods are on his side.He went on to apply these pragmatic lessons in action when he decided to lead various mass movements in the state, highlighting the problems faced by landless farmers and bonded labourers.Yeddyurappa never misses an opportunity to visit temples when he is confronted by crisis but he was not lucky this time after he was severely indicted by Lokayukta Santosh Hegde on corruption charges. He was named after presiding deity of a Shaivite temple built by the saint Siddalingeshwar at Yedeyur, in Tumkur district.advertisementOn a couple of occasions before his fate was almost sealed but Yeddyurappa had the last laugh as he battled a spate of allegations of multi-crore land scams, nepotism and open violation of rules to favour his kith and kin.Yeddyurappa managed to rally round his party MPs and loyalists after remaining defiant and keeping the top brass guessing on his moves when he was once asked to resign by the BJP leadership.Yeddyurappa, whose end as chief minister once seemed almost certain, with a smug opposition and his detractors within the party triumphant over delivering what they believed were deadly blows, has managed to carry the day with the party asking him to stay on.A graduate in arts, Yeddyurappa once warned the central leadership that his exit would mean the end of the party government as well, a threat which made the senior leaders to do a rethink on their decision before to ask him to quit.Sometimes. he also brought out an ace up his sleeve, the Lingayat caste card.He belongs to the Lingayat community which constitute nearly a fifth of the population in Karnataka and also a strong support base for the BJP. He also managed to rally influential seers around him, and got them to support him.In November 2010, Yeddyurappa was alleged to have used his position as chief minister to unfairly favour his sons in the allotment of prime land in Bangalore triggering another round of crisis. On February 5, 2011, Yeddyurappa publicly declared his assets, and then challenged the opposition and the Congress to find any “black money”.Yeddyurappa, who began his rule on sticky wicket in May 2008 falling short of a majority in the Assembly, cobbled up a slender majority by luring opposition MLAs and independents who were made to resign and contest bypolls.His gambit called ‘Operation Lotus’ paid off in enabling the BJP to secure the majority in the 224-member House.But the troubles did not seem to die down with the powerful Reddy brothers, ministers and mining magnates – Janardhana and Karunakara – launching a campaign for his removal.The BJP high command’s intervention ensured his survival before another wave of dissidence engulfed his government.As many as 11 BJP rebel MLAS and five independents withdrew support to his government, pushing it to a precipice.This too he survived, winning the trust vote twice – the first one, carried by voice vote, called unconstitutional by Governor H R Bhardwaj forcing him to face another floor test which he won by 106-100 votes.Yeddyurappa, who was often at loggerheads with Bhardwaj, went down in the Indian legislative history to be the only chief minister to survive two trust motions in a week’s time.Just as he seemed to have surmounted the crisis with the high court verdict upholding the disqualification of 11 rebel MLAs coming as a shot in the arm, trouble erupted again as the JDS levelled a series of allegations about land scams involving his family.advertisementHe rose to prominence when he helped JD(S)’ Kumaraswamy to bring down the coalition government of Dharam Singh of Congress. Kumaraswamy formed the government with the help of the BJP headed by Yeddyurappa.A deal was struck between the JD(S) and BJP, which specified that Kumaraswamy would be the chief minister for the first 20 months, after which Yeddyurappa would succeed him for the remaining 20 months of the tenure of the legislature.Yeddyurappa was nominated as the deputy chief minister as well as the finance minister in Kumaraswamy’s government.However, in October 2007, when Yeddyurappa’s turn of becoming the chief minister was supposed to start, Kumaraswamy refused to resign from his post.This forced Yeddyurappa and all of the ministers from his party to resign and on October 5, he met the governor and formally withdrew the BJP’s support from the government.Karnataka was put under President’s rule which was revoked on November 7.During the period of the President’s rule, the JD(S) and the BJP decided to bury their differences and this paved the way for Yeddyurappa to become the chief minister.Yeddyurappa was sworn in on November 12, 2007. However, JDS refused to support his government over disagreement on sharing of ministries which made him resign from his post on November 19, 2007.Born to Siddalingappa and Puttathayamma in Bookanakere in Mandya district in the state on February 27, 1943, the BJP leader lost his mother when he was just four-years-old.However, his determination to rise above all odds saw him overcoming the personal tragedy and move on in life.Yeddyurappa, was elected as President, Shikaripura Taluk Jana Sangha in 1972, marking his debut in public life.His leadership skills got an early start when he became the secretary of the Janata Party in 1977.His forte in taking up peoples’ issues, was amply illustrated when he spearheaded a team of 1,700 bonded labourers to Shimoga Deputy Commissioner’s Office demanding the release and rehabilitation of such labourers.A farmer himself, it was under his leadership that the movement for upholding the rights of ryots who were cultivating on government land unauthorisedly gained momentum.This missionary zeal brought some sufferings too. He was imprisoned during emergency in India between 1975 and 1977 and spent his days in Bellary and Shimoga jails.In 1965, he got a job of a first-division clerk in the social welfare department but instead shifted to Shikaripur where he joined as a clerk at his relative’s rice mill. In 1967, Yeddyurappa married Mythradevi, the daughter of the owner of the rice mill Veerabhadra Shastri. He later set up a hardware shop in Shimoga.Yeddyurappa’s true political career began when in 1983 he was first elected to the Assembly and he has represented Shikaripur constituency from then on for five times.His leadership skills were recognised by the central leadership of BJP and he was made the president of the state unit twice. He was also the national secretary in 1992.advertisementThe “yatri” in him is always at work. To improve the lives of marginalized, poor and gullible farmers, Yeddyurappa has taken up many yatras through the entire length and breadth of the state.Born on February 27, 1943 Yeddyurappa has two sons and three daughters. In 2004, his wife died after falling into and drowning in a nearby well under mysterious circumstances. No case was registered.-With PTI inputs
