Piezoelectricity is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat. It is derived from Ancient Greek πιέζω (piézō) 'to squeeze or press' and ἤλεκτρον (ḗlektron) 'amber'. The German form of the word (Piezoelektricität) was coined in 1881 by the German physicist Wilhelm Gottlieb Hankel; the English word was coined in 1883.
Flooring is the general term for a permanent covering of a floor, or for the work of installing such a floor covering. Floor covering is a term to generically describe any finish material applied over a floor structure to provide a walking surface. Both terms are used interchangeably but floor covering refers more to loose-laid materials.
Dupont Circle is a historic roundabout park and neighborhood of Washington, D.C., located in Northwest D.C. The Dupont Circle neighborhood is bounded approximately by 16th Street NW to the east, 22nd Street NW to the west, M Street NW to the south, and Florida Avenue NW to the north. Much of the neighborhood is listed on the National Register of Historic Places. However, the local government Advisory Neighborhood Commission and the Dupont Circle Historic District have slightly different boundaries.
A data center is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems.
Energy harvesting (EH) – also known as power harvesting,energy scavenging, or ambient power – is the process by which energy is derived from external sources, then stored for use by small, wireless autonomous devices, like those used in wearable electronics, condition monitoring, and wireless sensor networks.
Interface, Inc. is a global manufacturer of commercial flooring with an integrated collection of carpet tiles and resilient flooring, including luxury vinyl tiles (LVT) and nora brand rubber flooring.
An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, or the need for slip rings or yaw mechanism. An electrical generator may be on the ground or airborne. Challenges include safely suspending and maintaining turbines hundreds of meters off the ground in high winds and storms, transferring the harvested and/or generated power back to earth, and interference with aviation.
A raised floor provides an elevated structural floor above a solid substrate to create a hidden void for the passage of mechanical and electrical services. Raised floors are widely used in modern office buildings, and in specialized areas such as command centers, Information technology data centers and computer rooms, where there is a requirement to route mechanical services and cables, wiring, and electrical supply. Such flooring can be installed at varying heights from 2 inches (51 mm) to heights above 4 feet (1.2 m) to suit services that may be accommodated beneath. Additional structural support and lighting are often provided when a floor is raised enough for a person to crawl or even walk beneath.
Underfloor heating and cooling is a form of central heating and cooling that achieves indoor climate control for thermal comfort using hydronic or electrical heating elements embedded in a floor. Heating is achieved by conduction, radiation and convection. Use of underfloor heating dates back to the Neoglacial and Neolithic periods.
Pacesetters was a proposed energy-harvesting scheme created by Facility Architects, a London-based design firm. Its announced aim was to harness the vibrations generated by activities within a city and generate electricity for lighting purposes. The electronics company Philips and Hull University also took part in the project.
The Energy Technologies Institute (ETI) was a public-private partnership between global energy and engineering companies and the UK Government that was established in the United Kingdom in 2007. The government set up the ETI following an announcement in the 2006 budget speech. The purpose of the ETI is to “accelerate the development, demonstration and eventual commercial deployment of a focused portfolio of energy technologies, which will increase energy efficiency, reduce greenhouse gas emissions and help achieve energy and climate change goals”. The institute works with a range of academic and commercial bodies.
Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or façades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with similar technology. The advantage of integrated photovoltaics over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labor that would normally be used to construct the part of the building that the BIPV modules replace. In addition, BIPV allows for more widespread solar adoption when the building's aesthetics matter and traditional rack-mounted solar panels would disrupt the intended look of the building.
Subsea technology involves fully submerged ocean equipment, operations, or applications, especially when some distance offshore, in deep ocean waters, or on the seabed. The term subsea is frequently used in connection with oceanography, marine or ocean engineering, ocean exploration, remotely operated vehicle (ROVs) autonomous underwater vehicles (AUVs), submarine communications or power cables, seafloor mineral mining, oil and gas, and offshore wind power.
The Michigan Alternative and Renewable Energy Center (MAREC) was a facility located in Muskegon, Michigan that promoted research, education and business development in alternative and renewable energy technologies. In May 2016, the Center was renamed the Muskegon Innovation Center and the organization refocused on supporting innovation and entrepreneurship.
The Crowd Farm is a project conceived by MIT students Tad Juscyzk and James Graham and announced at the Holcim Forum 2007 awards ceremony. The goal of the project is to convert the energy of human movement in urban settings to energy suitable for consumer use.
Marine energy or marine power refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world's oceans creates a vast store of kinetic energy, or energy in motion. Some of this energy can be harnessed to generate electricity to power homes, transport and industries.
Shell LiveWIRE is a UK-wide enterprise scheme to help support young entrepreneurs into business.
Electric armour or electromagnetic armour is a type of reactive armour proposed for the protection of ships and armoured fighting vehicles from shaped charge and possibly kinetic weapons using a strong electric current, complementing or replacing conventional explosive reacting armour (ERA).
Jessica O. Matthews is a Nigerian-American inventor, Founder, CEO and venture capitalist. She is the co-founder of Uncharted, which made Soccket, a soccer ball that can be used as a portable power generator. Matthews attended Harvard College and graduated from Harvard Business School. In 2011, Fortune named her one of its "10 Most Powerful Women Entrepreneurs" and in 2015, named her as one of it "Most Promising Women Entrepreneurs". In 2012, the Harvard Foundation for Intercultural and Race Relations named her "Scientist of the Year." Matthews is a dual citizen of the U.S. and Nigeria. The President of Nigeria named her an "Ambassador for Entrepreneurship" for the country.
