Book Synopsis The Secret Life of Boilers by : George James Bennett

Book excerpt: Residential space and water heating accounts for 23% of UK final energy demand and combination gas boilers are the dominant technology. Performance gap issues in gas boiler systems have been reported, with previous studies unable to isolate or quantify root causes for performance issues. Dynamic behaviour of boiler heating systems is important to their overall performance, issues of plant size, supply temperature regulation and system control effect the performance of the system. The UK Standard Assessment Procedure (SAP), contains simplifications to aid ease of use and comparability of resulting Energy Performance Certificates (EPC) but they partly overlook these key dynamic issues. Three complementary methods were used to analyse heating system dynamics; a cross-model comparison, real world data from four case studies and a statistical analysis of a 217 boilers sample. Comparing SAP with a dynamically modelled system, showed that SAP results correspond closely to a model using an idealistic heating system, with perfect control and instant responsiveness. Introduction of a physically realistic gas fired boiler and water-based heating system to the model results in a consistent increase in internal temperature (0.5°C) and energy demand (ca. 1000 kWh/a). Variation of controls and plant size show an efficiency penalty for oversized boilers with limited modulation and poor thermostat controls. The key issue of boiler cycling was highlighted as a dynamic symptom of poor efficiency performance. From in situ analysis of boilers, cycling behaviour was observed indicating widespread performance reduction, as was seen in simulation. Most observed combi-boilers appear oversized for space heating and despite available modulation are unable to prevent rapid on-off cycling. Per day, half of combi boilers studied average more than 50 starts and 70% of cycles average less than 10 minutes during space heating operation. Boiler dynamic performance is not reflected in UK and EU efficiency testing standards, which assume steady state operation. The characterisation of the dynamics of gas boilers highlights issues of oversizing and excessive cycling, and reveals opportunities to improve the current building stock energy demand/emissions through better installations, EPCs, and energy labelling.
Book Synopsis The Secret Life of Stuff by : Julie Hill
Download or read book The Secret Life of Stuff written by Julie Hill and published by Random House. This book was released on 2011-01-06 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wouldn't you like: - Products that don't damage the environment? - A better way of life without agonising about your 'footprint'? - To really know your stuff? Climate change? Biofuels? Nuclear power? Landfills? Recycling? Renewable energy? Environmental issues can feel overwhelming. But, in fact, it is simple; it all comes down to one thing - stuff. Our use of the Earth's resources - whether a crisp packet or a cargo ship, a T-shirt or a wind turbine - has an inescapable impact on our future. In The Secret Life of Stuff, Julie Hill uncovers the origins and the true cost of what we use. Her inventory of over-consumption may shock but it is the first step towards overcoming waste. The misuse of stuff is not your fault, it's a product of history. But it is only by understanding what has gone wrong, that everyone - politicians, business people and us as consumers - can create a new and better material world.

Available in PDF, EPUB and Kindle. Book excerpt: Winner of the Mr. Christie's Book Award and the Hackmatack Children's Choice Book Award Owen Skye is skinny and quiet and has big ears. He does everything (just about) his older brother, Andy, says, while trying to stay one step ahead of little brother Leonard, who has now started school and is becoming smart at an alarming pace. The Skye brothers live in a small rural village with their parents and weird Uncle Lorne, an eccentric and painfully shy bachelor who sleeps on a cot in the basement, takes out his teeth at night and embodies Owen's worst fears about becoming a grownup. On his way home from hockey practice one evening, Owen catches a glimpse of a girl named Sylvia at her piano lesson, and he falls hopelessly in love. Thank goodness for life at home, where there are brothers to talk to and plot adventures with. Yet the Skye boys somehow have a knack for turning every innocent plan into a full-scale ordeal.
Book Synopsis The Secret Life of the Universe by : Amy Corzine
Download or read book The Secret Life of the Universe written by Amy Corzine and published by Watkins Media Limited. This book was released on 2012-01-01 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blending Eastern and Western philosophies with insights into nature, ecology, and physiology, this exploration of the place of humankind within the universe —and our individual stations—is both intellectual and approachable. Thinkers, writers, scientists, and educators of all stripes come together to examine subjects ranging from the nature of reality to brain science to the impact of technology on our world views, and more. They reveal that "the universe" may actually be comprised of multiple "universes" that overlap like the skin of an onion; peel away one layer of reality, and there’s others waiting to be experienced, if not completely understood. The book presents intriguing ideas from visionaries ranging from Jesus to Galileo, Newton to Descartes, and Kant to Einstein, among many others.

Available in PDF, EPUB and Kindle. Book excerpt: Using exclusive access to newly uncovered archives, Kalush and Sloman reveal the clandestine agreements in which the British and Americans recruited Houdini to be an active secret agent. In exchange for his cooperation, the governments of these two countries facilitated his rise to the top of the world stage. The authors give thrilling accounts of his assignments, such as his participation in early aerial surveillance and his use of his own magic magazine to communicate espionage-related information. After the war, Houdini embarked upon what became his most dangerous mission when he took on the Spiritualist movement. Convinced that Spiritualist mediums were frauds, he became obsessed with exposing them. But the Spiritualists were a powerful adversary. An organized network of fanatics, led by Sherlock Holmes creator Arthur Conan Doyle, worked relentlessly to orchestrate a campaign that would silence Houdini forever. Grounded in solid research, but as exciting and dramatic as a good thriller, THE SECRET LIFE OF HOUDINI traces the magician's long and circuitous route from struggling vaudevillian to worldwide legend.

Available in PDF, EPUB and Kindle. Book excerpt: Ben Ketchum is a microbiologist who lives in Montana and has just one year left to gain his tenure. Ben also lost his anthrax grant so now he's forced to turn to the brewer's yeast, a microbe he knows virtually nothing about, just to keep his lab up & running. On a whim, the bacteriologist buys a ticket to Egypt - birthplace of perhaps the world's oldest civilization - where he learns about the yeast's role in building the pyramids, as well as the history of brewing, baking, and winemaking. Next, Ben travels to a more recent example of a beer culture - Germany - where he learns the yeast's role in bringing about Western civilization including the field of biochemistry. Lastly, Ben attends a symposium on the brewer's yeast, where he uncovers all the ways the yeast has been helping scientists accomplish such diverse tasks as manufacturing valuable human proteins and even gaining insight into the origins of cancer. This is part one of a longer novel ""Cystic Fibrosis & the Brewer's Yeast.""

Book Synopsis The Secret World by : Christopher M. Andrew
Download or read book The Secret World written by Christopher M. Andrew and published by Yale University Press. This book was released on 2018-01-01 with total page 993 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first-ever detailed, comprehensive history of intelligence, from Moses and Sun Tzu to the present day The history of espionage is far older than any of today's intelligence agencies, yet the long history of intelligence operations has been largely forgotten. The codebreakers at Bletchley Park, the most successful World War II intelligence agency, were completely unaware that their predecessors in earlier moments of national crisis had broken the codes of Napoleon during the Napoleonic wars and those of Spain before the Spanish Armada. Those who do not understand past mistakes are likely to repeat them. Intelligence is a prime example. At the outbreak of World War I, the grasp of intelligence shown by U.S. President Woodrow Wilson and British Prime Minister Herbert Asquith was not in the same class as that of George Washington during the Revolutionary War and leading eighteenth-century British statesmen. In this book, the first global history of espionage ever written, distinguished historian Christopher Andrew recovers much of the lost intelligence history of the past three millennia--and shows us its relevance.
