The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons. Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms. Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.
Selected article
An air well or aerial well is a structure or device that collects water by promoting the condensation of moisture from air.[1] Designs for air wells are many and varied, but the simplest designs are completely passive, require no external energy source and have few, if any, moving parts. Three principal designs are used for air wells: high mass, radiative and active. High-mass air wells were used in the early 20th century, but the approach failed.[2] From the late 20th century onwards, low-mass, radiative collectors proved to be much more successful.[2] Active collectors collect water in the same way as a dehumidifier; although the designs work well, they require an energy source, making them uneconomical except in special circumstances.

Featured biography
Albert Stanley, 1st Baron Ashfield (1874–1948) was managing director, then chairman of the Underground Electric Railways Company of London (UERL) from 1910 to 1933 and chairman of the London Passenger Transport Board (LPTB) from 1933 to 1947. At a young age, he held senior positions in the developing tramway systems of Detroit and New Jersey. In 1907, his management skills led to his recruitment by the UERL, which was struggling through a financial crisis. He quickly integrated the company's management and used advertising and public relations to improve profits. As managing director of the UERL from 1910, he led the take-over of competing underground railway companies and bus and tram operations to form an integrated transport operation known as the Combine. He was Member of Parliament for Ashton-under-Lyne from December 1916 to January 1920 and was President of the Board of Trade between December 1916 and May 1919. He returned to the UERL and then chaired it and its successor the LPTB during the organisation's greatest period of expansion between the two World Wars, making it a world-respected organisation considered an exemplar of the best form of public administration.
