The neutron is a subatomic particle, symbol which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.

A neutrino is a fermion (an elementary particle with spin of 1/2) that interacts only via the weak interaction and gravity.

An object with an absence of net charge is referred to as neutral.

Network analysis is the process of finding the voltages across, and the currents through, all network components.

Buildings that have been constructed with renewable energy features that allow self sustainability and balancing of energy from grid power and self produced energy.

A method of construction of machinery that includes independent modules that when combined makeup the larger machine. The modules can easily be exchanged when maintenance or repair is required thereby reducing downtime.

Modeling and simulation is the use of models as a basis for simulations to develop data utilized for managerial or technical decision making.

Miscibility is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous mixture (a solution).

Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts.

Mineral-insulated copper-clad cable is a variety of electrical cable made from copper conductors inside a copper sheath, insulated by inorganic magnesium oxide powder.

The Mine Safety and Health Administration is a large agency of the United States Department of Labor which administers the provisions of the Federal Mine Safety and Health Act of 1977 (Mine Act) to enforce compliance with mandatory safety and health standards as a means to eliminate fatal accidents, to reduce the frequency and severity of nonfatal accidents, to minimize health hazards, and to promote improved safety and health conditions in the nation's mines

The oil and gas industry is usually divided into three major components: upstream, midstream and downstream.

A microwave power meter is an instrument which measures the electrical power at microwave frequencies typically in the range 100 MHz to 40 GHz.

A very small wind turbine which is used for small energy needs for cabins, campers, sailboats, very small communication stations, or other small off-grid loads.

Microscale meteorology is the study of short-lived atmospheric phenomena smaller than mesoscale, about 1 km or less.

The use of small generators or devices to convert power into electricity.

Microgrids are designed to add protection to an area that is reliant on a constant electrical supply such as airports. In the event of grid power failure the microgrid will become active.

Small scale generation of heat and electricity by individuals, comminities or businesses as power alternatives or additions to existing power resources.

A local set of atmospheric conditions that differ from those in the surrounding areas, often with a slight difference but sometimes with a substantial one.

A bio-electrochemical system that drives an electric current by using bacteria and a high-energy oxidant such as O2.
