As far back as 1873, experiments were carried out to see whether the electric trolley system applied to omnibuses could be adapted to ploughing and tilling fields. In 1913, 1,600 “trolley/cable ploughs were in use across German farmlands. The arrival of the gasoline tractor relegated the use of electricity to electroculture, short haul farm machinery and lawn mowers. But it is only with the commercial availability of the lithium-ion battery during the last decade, that electrically powered drones and more recently tractors and earth movers are being seen as the way ahead. In this, the sixth in his seminal electric transport history series, Kevin Desmond portrays the life and work of the innovative engineers who perfected these e-tractors and agricultural drones.
There are twenty million acres of lawns in North America. In their current form, these unproductive expanses of grass represent a significant financial and environmental cost. However, viewed through a different lens, they can also be seen as a tremendous source of opportunity. Access to land is a major barrier for many people who want to enter the agricultural sector, and urban and suburban yards have huge potential for would-be farmers wanting to become part of this growing movement. The Urban Farmer is a comprehensive, hands-on, practical manual to help you learn the techniques and business strategies you need to make a good living growing high-yield, high-value crops right in your own backyard (or someone else's). Major benefits include: Low capital investment and overhead costs Reduced need for expensive infrastructure Easy access to markets Growing food in the city means that fresh crops may travel only a few blocks from field to table, making this innovative approach the next logical step in the local food movement. Based on a scalable, easily reproduced business model, The Urban Farmer is your complete guide to minimizing risk and maximizing profit by using intensive production in small leased or borrowed spaces. Curtis Stone is the owner/operator of Green City Acres, a commercial urban farm growing vegetables for farmers markets, restaurants, and retail outlets. During his slower months, Curtis works as a public speaker, teacher, and consultant, sharing his story to inspire a new generation of farmers.
The third edition of this book exposes the reader to a wide array of engineering principles and their application to agriculture. It presents an array of more or less independent topics to facilitate daily assessments or quizzes, and aims to enhance the students' problem solving ability. Each chapter contains objectives, worked examples and sample problems are included at the end of each chapter. This book was first published in the late 60's by AVI. It remains relevant for post secondary classes in Agricultural Engineering Technology and Agricultural Mechanics, and secondary agriculture teachers.
This bulletin provides principles, practices and procedures for testing machines and also determines aspects of a machine's performance that can be evaluated. It is directed towards those involved in the evaluation of machinery, and primarily towards users on small farms. Evaluation of farm equipment may be appropriate at any stage in its development, from first prototype to batch and series production.
Agricultural mechanization is the use of power and machinery to produce food and fiber. This has included the development of agricultural tools and machines, energy and power, irrigation and drainage, structures for animal housing and crop storage, and electrification. - p. 3.
This framework presents ten interrelated principles/elements to guide Sustainable Agricultural Mechanization in Africa (SAMA). Further, it presents the technical issues to be considered under SAMA and the options to be analysed at the country and sub regional levels. The ten key elements required in a framework for SAMA are as follows: The analysis in the framework calls for a specific approach, involving learning from other parts of the world where significant transformation of the agricultural mechanization sector has already occurred within a three-to-four decade time frame, and developing policies and programmes to realize Africa’s aspirations of Zero Hunger by 2025. This approach entails the identification and prioritization of relevant and interrelated elements to help countries develop strategies and practical development plans that create synergies in line with their agricultural transformation plans. Given the unique characteristics of each country and the diverse needs of Africa due to the ecological heterogeneity and the wide range of farm sizes, the framework avoids being prescriptive.
This book endeavors to break the stereotype that basic electrical machine courses are limited only to transformers, DC brush machines, induction machines, and wound-field synchronous machines. It is intended to serve as a textbook for basic courses on Electrical Machines covering the fundamentals of the electromechanical energy conversion, transformers, classical electrical machines, i.e., DC brush machines, induction machines, wound-field rotor synchronous machines and modern electrical machines, i.e., switched reluctance machines (SRM) and permanent magnet (PM) brushless machines. In addition to academic research and teaching, the author has worked for over 18 years in US high-technology corporative businesses providing solutions to problems such as design, simulation, manufacturing and laboratory testing of large variety of electrical machines for electric traction, energy generation, marine propulsion, and aerospace electric systems.
Agricultural and Horticultural Engineering: Principles, Models, Systems, and Techniques focuses on the developments in agriculture and horticulture, including the role of engineers in employing measures in the management of plants, animals, and machinery. The book first offers information on the process of surveying, including tape, compass, and aerial surveying, leveling, barometric leveling with the aneroid, plane tabling, and electronic distance measurement and electronic total. The text then takes a look at models of the environment, material properties, and the relationship between stress and strain. The publication examines workshop methods and hydraulics. Topics include soldering, electric arc welding, low temperature brazing, welding using oxygen-acetylene apparatus, hydrodynamics, and water supply requirements. The text also reviews electricity and electronics and power and thermal systems, as well as alternating voltage supplies, electrical motors, electrical safety, power and energy consumption, and the fundamental principles of electronics. The manuscript is a dependable reference for engineers and readers interested in agricultural and horticultural engineering.
