Optimal Energy Joule
2014-06-18 06:24:29

The Joule was produced by Optimal Energy based in Cape Town, South Africa. It was an electric six-seat passenger car first thought of in 2004. It was shown to the public at the 2008 Paris Motor Show. Changes were made and shown again at the 2010 Geneva Motor Show. Production of the Joule stopped in April 2012 and Optimal Energy announced it was closing down in June 2012. The Joule was an...

Solar Impulse
2014-04-11 10:27:07

The Solar Impulse is a Swiss made long-range solar-powered aircraft project. It was developed at the École Polytechnique Fédérale de Lausanne. The project’s goal is to circle the Earth with a piloted fixed-wing aircraft, powered only by solar energy. Bertrand Piccard, a Swiss aeronaut leads the project who was a co-pilot with Andre Borsch berg a Swiss businessman, in the first balloon to...

ZENN Motor Company
2014-01-06 10:48:03

The ZENN or "Zero Emissions No Noise" Motor Company is a Canadian company that initially produced small lead-acid electric vehicles. It is currently focused on gaining the rights to electric storage capacitor technology. Ian Clifford, Marek Warunkiewicz and Probyn Gayle are the co-founders of Feel Good Cars, later renamed ZENN Motor Company. The first prototype the company produced was a...

Stellar Astrophysics
2014-01-12 00:00:00

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that...

Antarctic Sea Urchin Sterechinus Neumayeri
2012-04-17 11:36:15

The Antarctic Sea Urchin (Sterechinus neumayeri), is a species of sea urchin in the family Echinidae. It is found in the Antarctic Ocean living on the seafloor. It is common around the circumpolar waters, including the Balleny Islands, South Georgia and the South Sandwich Islands, Terra Nova Bay, and Victoria Land. It is found at depths of about 820 feet. The colors of this species range...

Bolometer
2010-10-27 21:58:22

The bolometer, invented in 1878 by Samuel Pierpont Langley, measures the energy of incident electromagnetic radiation. It consists of an absorptive element connected to a heat sink through a thermal link. The absortive element raises its temperature above that of the heat sink when radiation impinges on it. The higher the energy the higher the temperature rises. Old bolometers used metals while...

Gas Stove
2010-09-24 16:20:41

A gas stove is a cooking device which uses natural gas, propane, butane, Liquefied petroleum gas or other flammable gas as a fuel source. Since the gas pipe network was slow to develop, the success of the gas stove on a commercial level took some time to happen. Gas stoves were invented as early as the 1820's as isolated experiments but it was not until the 1880's that manufactured stoves...

Vortex
2009-07-18 15:30:33

A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's...

Turbulence
2009-07-18 12:56:04

Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low...

Palo Santo Bursera graveolens
2009-04-28 16:00:11

Bursera graveolens or Palo Santo is a tree indigenous to South America in Argetina, Paraguay, Boliva and coastal areas of Ecuador. Palo Santo means "holy wood" in English and belongs in the same family as frankincense and myrrh. Although it has been used in homeopathic medicine for years, most recently it is the extraction of essential oils that has put this plant in the spotlight....

Word of the Day
bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
The word 'bretelles' comes from a French word meaning 'braces'.
