New infrastructure projects can have high costs and are often financed through debt. Many infrastructure owners, therefore, impose usage fees, such as landing fees at airports or toll plazas on roads. Independent of this, authorities may impose taxes on the purchase or use of vehicles.

Self-guiding agricultural machinery such as that sold by John Deere is all but robotic already. It is like an airliner, in which the pilot usually has little to do between landing and take-off because computers do the work for him. Yet Deere has no plans to hand over complete control to the cloud, because that is not what its customers want. Over the past few decades large corporations have grown up to supply the needs of commercial farming, especially in the Americas and Europe. Monsanto, another big American firm, is the subject of a takeover bid by Bayer, a German one.

In rich countries like Germany or the UK it is only 1 in 100 who is employed in agriculture. Similarly, productivity gains makes it possible to reduce the agricultural land needed to feed a given number of people. Both inland fish farming and urban vertical farming—though niche operations compared with Midwestern soyabean cultivation or Scottish sea-loch salmon farms—are waves of the future in the service of gustatorially sophisticated urbanites. And in these businesses, the idea of farm as factory is brought to its logical conclusion. Do this successfully, Dr Post reckons, and the cost would fall to $65 a kilogram. Dr Fahrenkrug has also been working on a famous mutation that increases muscle mass.

Hybrids improve the results of planting, and often produce plants and fruits that are hardier and more uniform. Hybrid seeds contributed to the increased agricultural output of the second half of the 20th century. Evidence suggests that irrigation first appeared in Egypt and Mesopotamia in the fourth millennium B.C. Floods caused by the yearly inundation of the Nile would have had disastrous effects for ancient farmers, washing away dikes and swamping fields.

Key specifications include the intended application, sensor/detector type, measurement range, and features. Gas and chemical sensors/detectors are used for confined space monitoring, leak detection, analytical instrumentation, etc. and are often designed with the capability of detecting multiple gases and chemicals. More information about gas and chemical sensors may be found in our related guide All About Gas and Chemical Sensors. Temperature Sensors/Detectors/Transducers are electronic devices that detect thermal parameters and provide signals to the inputs of control and display devices. A temperature sensor typically relies on an RTD or thermistor to measure temperature and convert it to an output voltage. Key specifications include sensor/detector type, maximum and minimum measurable temperatures, as well as the dimensions of diameter and length.

A Local Area Network is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building. The Internet of Things is a network of physical objects that are fitted with sensors, software and other technologies. Connected to the Internet, these ‘things’ are able to exchange real time data with other connected devices and systems over networks. These connected devices combine with automated systems to gather IoT data that can be analysed to assist with tasks or learn how to improve a process. Things have evolved due to the convergence of multiple technologies, real-time analytics, machine learning, ubiquitous computing, commodity sensors, and embedded systems.

A MAN is a series of connected LANs in a city, which might also connect to a WAN. ‍A campus network is a LAN or set of connected LANs which is used by a government agency, university, corporation or similar organization and is typically a network across a set of buildings that are close together. Live-streaming media, on-demand media, gaming companies, application creators, e-commerce sites—as digital consumption increases, more content owners turn to CDNs to better serve content consumers. A city government might manage a city-wide network of surveillance cameras that monitor traffic flow and incidents. This network would be part of a MAN or metropolitan area network that allows city emergency personnel to respond to traffic accidents, advise drivers of alternate travel routes, and even send traffic tickets to drivers who run red lights. Message switching sends a message in its entirety from the source node, traveling from switch to switch until it reaches its destination node.
