This is a very well done guide to sealing up air leaks in your home. Lots of good how-to pictures. A couple small add-ons I would make: - Replacing older can lights so that you can insulate right over them is a fairly easy DIY job -- it has the advantages of both reducing heat loss to the attic and getting some heat gain from the can light to the room. - The method they give for determining if you have enough insulation is goofy. Instead, use the Insulation Upgrade Calculator or one of the online insulation guides to determine if your insulation is sufficient for your climate.

High Quality illustrated textbook. This book is meant for students in their introductory heat transfer course —students who have learned calculus (through ordinary differential equations) and basic thermodynamics. It includes the needed background in fluid mechanics, although students will be better off if they have had an introductory course in fluids.

A fascination for wind energy has driven both of us to build, buy, install, and maintain our own machines for the last three decades. Chances are that the first wind-energy users were driven by the same maniacal glee that we experience when we grab energy out of thin air. The design of home-scale wind-electric generators has been through many permutations and variations, with lots of circles and dead ends

Hydropower offers expanding opportunities to increase generation based on renewable, domestic, carbon-free technologies. This report presents a review of the possible contribution of waterpower technologies in the near-term (by 2010) and long-term (by 2025) to the U.S. renewable energy supply. Segments of the waterpower industry include conventional hydroelectric plants and emerging technologies that access the energy in river and tidal currents (hydrokinetic) as well as in ocean waves. The report documents how each segment of waterpower technology can contribute to increased production, discusses research questions that need to be answered to achieve the desired results, and reviews targeted economic incentives that can spur waterpower production.

- Investigate the key issues, especially including safety, associated with the installation of building integrated photovoltaics (BIPV).

- Describe design and installation solutions that are acceptable to the building services industry and the relevant regulatory authorities.

- Translate these solutions into practical and authoritative installation guidelines with a particular emphasis on the domestic BIPV sector.

This document contains some of the background information which was used by the writers to produce the guide, named “Photovoltaics in Buildings: Guide to the installation of PV systems” (DTI/Pub URN 02/788). The guide itself contains the considered recommendations of the group after consultation with people in the industry. As such it constitutes the definitive material, not this report. Sometimes the information in this report is not conclusive and may at times present apparently conflicting pieces of information. Nevertheless decisions had to be made in the course of producing the guide which are sometimes based on caution or lack of substantiated background material. This report should be read in conjunction with the guide itself and may present the reader with some useful background information, but will not always be sufficient to fully explain the decisions in the guide. The guide was produced with the assistance of a Steering Committee to review progress from time to time. They consisted of the: ECA - The Electrical Contractor Association, who wish to see clear guidance targeted at their members for their own interest. HSE- The Health and Safety Executive had valuable input to the guide, as well as approving the health and safety aspects. NHBC- The National House Building Council, who publish codes of practice for the building trades and have a strong interest in technical standards from an insurance point of view. PV-UK – The British Photovoltaic Association, who has an obvious interest and have stated there is a need for such a guide. The guide concentrates on the electrical aspects of the installation, as the guide is for installers rather than designers, and it was assumed that the installer is more likely to be an electrician than from any other trade. There was to have been a section on the construction aspects but, because of the huge range of possible mounting methods, only one of which would be relevant for any particular installation, the section had to be either very large or had be pared down to a simple list. In the end it was decided to leave these things to the designer, but make the installer aware of them in the checklist. Generally suppliers can provide comprehensive installation advice as it relates to their particular product.

Some of the source documents, particularly Engineering recommendation G77 and part 712 of IEC60364, are in draft form. Where this is the case, the version at February 2002 should be considered as the version under discussion.

In this application note, wind turbine technology is presented as a serious alternative for achieving sustainable energy policy objectives. Several European countries have impressive plans for the coming years for installing large amounts of wind power generation. Some governments support these actions by providing tax or investment incentives. The northwest of Europe with its coastal windy waters and fine-meshed but strong electric grid give promising opportunities for investing companies and wind farm developers.

As many small-scale methods of electricity generation are available only intermittently, some form of electricity storage or battery is needed if people want to have electricity available at all times.

There are a wide range of batteries available, and the aim of this Technical Brief is to give an introduction to the advantages and disadvantages of the different types of batteries. The central point is that there is no such thing as a universal battery; a single type of battery cannot cover all applications.

Honey has a long and distinguished history in the human diet. For thousands of years honey hunters have plundered the hives of wild bees for their precious honey and beeswax - a practice still common today.

The most widely used honeybees are the European Apis mellifera, which have now been introduced worldwide. Tropical Africa has a native Apis mellifera, which is slightly smaller than the European Apis mellifera, and is more likely to fly off the comb and to sting. They are also more likely to abandon their hives if disturbed, and in some areas the colonies migrate seasonally.

In Asia there are three main native tropical species, Apis cerana, Apis dorsata, and Apis florea; cerana is the only species that can be managed in hives, but the single combs of the other two are collected by honey hunters.

This second edition of the very popular and rare title 'Belt and Bucket Elevator Design' consists of even more details to use in the industrial design engineering, fabrication and care of belt and bucket elevators. Critical information and engineering decision detail has been added on bearing selection, shaft seal, belt tension, dust extraction, hazardous applications, drive selection and more on proper use and care for operators and maintainers. The first edition covered a good amount of design engineering detail and calculation. It ended with additional operating and maintenance information to provide a more complete understanding of the use of belt bucket elevators used for bulk material handling equipment. This second edition adds more detail and information on many of the numerous other industrial design engineering decisions to be made when building and maintaining belt bucket elevators. The format of this edition remains unchanged. The bucket elevator design information is presented first followed by important information on the other factors that influence its successful industrial design, use and care. The author gives valuable knowledge about his experiences with bucket elevators. Bucket elevators lift bulk materials from one level to another and function well when designed properly for the duty, and are used as designed. Since bucket elevators are used on powders, granules, grain, chip shaped products, lumpy materials and hazardous material handling, problems can occur. Mike notes possible remedies in his white paper.

With shortages of fossil energy, especially oil and natural gas, and heavy biomass energy use occurring in both developed and developing countries, a major focus has developed worldwide on renewable energy systems. Renewable energy systems include wind power, biomass, photovoltaics, hydropower, solar thermal, thermal ponds, and biogas. Currently, a heavy focus is on biofuels made from crops, such as corn, sugarcane, and soybeans, for use as renewable energy sources. Wood and crop residues also are being used as fuel. Though it may seem beneficial to use renewable plant materials for biofuel, the use of crop residues and other biomass for biofuels raises many concerns about major environmental problems, including food shortages and serious destruction of vital soil resources. All renewable energy systems need to be investigated because humankind has only about 40 years of oil and gas reserves remaining. There is a 50 to 100 year supply of coal resources in the ground, but coal will become increasingly difficult to extract and will greatly increase the global warming threat. Serious energy conservation and research on viable renewable energy technologies are needed. This book considers the effectiveness and economics of several renewable energy technologies of current interest, including biofuels, solar and wind

This guide is 142 pages and well illustrated with diagrams and tables.

From the preface

An important common theme underlies much of the current literature on the application of technology within both developed and developing nations. Any technology has a complex series of impacts on the environment in which that technology operates. The concern over a technology's "appropriateness" is based on the need to determine clearly who will be affected by use of the technology and in what ways* Behind the concept of "appropriate technology" is the belief that the complex interactions between a technology and its environment should be made "visible." Only then can a technology be evaluated properly. By describing explicitly the impact of a technology, the selection criteria for the technology also become explicit. If we choose a technology that pollutes a river, but which also provides permanent jobs for 10,000 workers, we presumably either value employment benefits over environmental costs or else were ignorant of the pollution effects at the time we made the decision.

The choice of a technology is "appropriate" or "inappropriate" only in the context of the demands we place upon it. The subtle trade-offs between these often conflicting demands are at the real core of any debate over the choice of a technology. Appropriate technology is less a problem of hardware than of appropriate data collection, decision-making, financing, installation, and use-- with all the problems of sorting out competing demands and value judgements in each of these tasks. This study is an assessment of the "appropriateness" of biogas technology in meeting some of the needs of India's rural population. Such an assessment is quite complicated, despite claims that a biogas system is a simple village-level technology. While there is evidence that biogas systems have great promise, they are subject to certain constraints. It is impossible to describe here all the factors that one might study to assess any technology. I only hope that the approach used in this study will help others.

One difficulty in studying biogas technology is the fragmented and often anecdotal nature of the research and development work. In order to provide this snapshot of the state-of-the-art in India, I have had to enlist the aid of a bewildering number of government officials, industrialists, university researchers, missionaries, social workers, journalists, voluntary groups I farmers, merchants, and villagers.
