Dean Lawrence Kamen is an American engineer, inventor, and businessman. He is known for his invention of the Segway and iBOT, as well as founding the non-profit organization FIRST with Woodie Flowers. Kamen holds over 1,000 patents.
Manchester is the most populous city in the U.S. state of New Hampshire and in northern New England. At the 2020 census, it had a population of 115,644.
A Stirling engine is a heat engine that is operated by the cyclic compression and expansion of air or other gas between different temperatures, resulting in a net conversion of heat energy to mechanical work.
North Dumpling Island is a two-acre (8,100 m2) island in Fishers Island Sound of Long Island Sound, one mi (1.6 km) off the coast of Connecticut, south of Groton, within the territory of the town of Southold on Long Island in New York State. The island is about 0.3 nmi (560 m) north of South Dumpling Island, and is home to the North Dumpling Light, which dates from 1859. The island is privately owned by Dean Kamen, inventor of the Segway.
An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke.
Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water was, formerly, the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodeionization. Combinations of a number of these processes have come into use to produce ultrapure water of such high purity that its trace contaminants are measured in parts per billion (ppb) or parts per trillion (ppt).
Environmental technology (envirotech) or green technology (greentech), also known as clean technology (cleantech), is the application of one or more of environmental science, green chemistry, environmental monitoring and electronic devices to monitor, model and conserve the natural environment and resources, and to curb the negative impacts of human involvement.
The iBOT is a powered wheelchair that uses gyroscopic technology to provide multiple operating modes for varied indoor and outdoor terrain.
The Manchester Transit Authority, or MTA, is a public transportation provider in Manchester, New Hampshire, United States. It was founded in 1973 and operates 13 regular bus routes through the city, including a free downtown circulator, which was rebranded as the Green DASH in 2011. In general, service is hourly, with more frequent service along corridors served by multiple routes, and especially on the Green DASH.
LifeStraw is a brand of water filtration and purification devices. The original LifeStraw was designed as a portable water filter "straw". It filters a maximum of 4,000 litres of water, enough for one person for three years. It removes almost all waterborne bacteria, microplastics and parasites. A bottle was later developed which incorporated a LifeStraw cartridge into a 650-millilitre (22 US fl oz) BPA-free plastic sports water bottle. In addition to these portable filters, the manufacturer produces high-volume purifiers powered by gravity that also remove viruses. These are designed for family and community use.
Portable water purification devices are self-contained, easily transported units used to purify water from untreated sources for drinking purposes. Their main function is to eliminate pathogens, and often also of suspended solids and some unpalatable or toxic compounds.
The Amoskeag Manufacturing Company was a textile manufacturer which founded Manchester, New Hampshire, United States. From modest beginnings it grew throughout the 19th century into the largest cotton textile plant in the world. At its peak, Amoskeag had 17,000 employees and around 30 buildings.
A slingshot is a small hand-powered projectile weapon.
The LifeSaver bottle is a portable water purification device. The bottle filters out objects larger than 15 nanometres.
Slingshot is a water purification device created by inventor Dean Kamen. Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source by means of vapor compression distillation, requires no filters, and can operate using cow dung as fuel.
Coca-Cola Freestyle is a touch screen soda fountain introduced by The Coca-Cola Company in 2009. The machine features 165 different Coca-Cola drink products, as well as custom flavors. The machine allows users to select from mixtures of flavors of Coca-Cola branded products which are then individually dispensed. The machines are currently located in major Coca-Cola partners and retail locations as a part of a gradual and ongoing deployment.
Segway Inc. is a Chinese owned, formerly American manufacturer of two-wheeled personal transporters, chiefly through its Segway PT and Segway miniPro product lines. Founded by inventor Dean Kamen in 1999, the company's name is a homophone of the word "segue".
Applications of the Stirling engine range from mechanical propulsion to heating and cooling to electrical generation systems. A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the "working fluid", at different temperature levels such that there is a net conversion of heat to mechanical work. The Stirling cycle heat engine can also be driven in reverse, using a mechanical energy input to drive heat transfer in a reversed direction.
ELGA LabWater is the laboratory water brand name of Veolia Water Solutions & Technologies. ELGA manufactures, supplies and services water purification systems for use in general, R&D, healthcare and clinical laboratories. Its offices and distributors are located in more than 60 countries.
Ada Henry Van Pelt was a temperance and suffrage activist, editor, lecturer, and, later in life, an inventor. She held several patents, including one for an electric water purifier, patented when she was 74 years old.
