A smart water network is a cohesive set of systems, products, and solutions that enable water utilities to remotely and continuously monitor and diagnose problems related to water distribution. Smart water networks are data-driven by information collected from the physical layers of pumps, pipes, reservoirs, and valves. The data helps optimize various aspects of a water distribution system in terms of pressure management, leak detection, water quality, and network operation. It can also reduce the overall capital expenditure of water utilities by providing real-time data based on water consumption and customer meter readings.

14185.全球DC电源系统市场报告（2015-2019年）
[计算机、通信和其他电子设备制造业,电力、热力、燃气及水生产和供应业,仪器仪表制造业] [2015-06-14]
DC power systems are electrical structures that supply voltage or current of fixed polarity, either positive or negative. Such systems can be powered by an alternating current (AC) or a direct current (DC) source. A simple DC power system consists of a transformer, rectifier, filter, and regulator, all of which work to provide a constant and ripple-free DC output. DC power systems largely find applications in telecommunications, data centers, and transportation. However, they are also used in the oil and gas, consumer electronics, and automotive industries.

Drill collars are an essential part of the drill string. They form the lowest component of the drill string. Drill collars are heavy, thick-walled steel pipes with threaded connections at both ends. The end with an external thread is known as the male end, whereas the end with an internal thread is known as the female end. The basic purpose of a drill collar is to provide the necessary weight for drilling purposes. Drill collars are machined out of solid steel bars as per API specifications. They are manufactured from standard steel (usually plain carbon steel) or a non-magnetic alloy of steel and copper or other non-magnetic alloys. The bars of solid steel are bored from one end to the other to provide passage for drilling fluids. There are usually two types of drill collar: slick and spiral. Standard drill collars are about 9 meters in length. Drill collars are characterized by high tensile strength and fatigue resistance. The various uses of drill collars are.

[电力、热力、燃气及水生产和供应业,电气机械和器材制造业] [2015-06-13]
A generator is a device that converts mechanical energy into electrical energy. Mechanical energy is produced by an internal combustion engine that uses fuel as an energy source. Generators provide backup power for industries, commercial offices, residences, construction sites, and workshops. Based on size, residential generators can be categorized into portable and stationary generators. Portable generators can be easily moved from one place to the other, making it suitable for residential applications. They provide a power output ranging between 500 W and 18 kW.

Smart grid sensors are compact electrical devices used to detect and monitor power system equipment. These sensors monitor electrical equipment such as transformers, arrestors, power cables, and other equipment installed in power plants, or substations, along with demand side management in smart grids. In addition, these devices also track the power line temperature and weather conditions around the power cables, and are used to calculate the line's current carrying capacity. They are also used in residential areas and offices to enhance energy efficiency.

14189.全球碳捕集与封存能源市场报告（2015-2019年）
[电力、热力、燃气及水生产和供应业,采矿业] [2015-06-13]
Carbon capture and storage technology captures and stores manmade carbon dioxide (CO2) instead of releasing it into the atmosphere. After the CO2 is captured at its source, such as a fossil fuel power plant, it is converted into a concentrated stream for transportation and storage. Carbon capture and storage is an emerging technology that is gaining in popularity as companies seek to keep up with stringent emission regulations and avoid the penalties that result from noncompliance.

A traction transformer is integral to the electric traction system; it helps in the smooth movement of motors such as locomotives, high-speed trains, and trams. These devices are used to reduce the voltage from overhead electric lines, i.e., from 15/25 kV to the desired voltage level, i.e., 0.7/1.5 kV. For over a century now, these transformers have been used in railway traction and are considered the best alternative to conventional fossil fuel-based traction systems.
