Fuel cell

Fuel cell
Demonstration model of a direct-methanol fuel cell. The actual fuel cell stack is the layered cube shape in the center of the image Scheme of a proton-conducting fuel cell The first fuel cells were invented in 1838. The first commercial use of fuel cells came more than a century later in NASA space programs to generate power for probes, satellites and space capsules. Since then, fuel cells have been used in many other applications. There are many types of fuel cells, but they all consist of an anode, a cathode and an electrolyte that allows charges to move between the two sides of the fuel cell. The fuel cell market is growing, and Pike Research has estimated that the stationary fuel cell market will reach 50 GW by 2020.[3] History[edit] Sketch of William Grove's 1839 fuel cell The first references to hydrogen fuel cells appeared in 1838. In 1939, British engineer Francis Thomas Bacon successfully developed a 5 kW stationary fuel cell. Types of fuel cells; design[edit] SOFC[edit]

A Quick Course in Creativity by Paul McNeese This quick course in creativity is designed to give you a platform to stand on as we look at the various ways you can handle home, social and workplace situations, job-search details and career-path decisions. Let's examine what creativity might look like. Here are some of the ways in which creativity expresses itself. Perhaps the creative idea is one that mixes and matches items or ideas that haven't been combined in just this way before. A wonderful example of this comes from Anita Roddick, who founded the Body Shop, a chain of personal care products and stores.

Patent US20040164824 - Hyperspace energy generator - Google Patenten [0072] 1. Referring to FIG. 15, the coaxial cable has a braided gold wire outer conductor (A) and a braided gold wire inner conductor (B) separated by a dielectric (C). The open braiding promotes the conduction of the electromagnetic wave while allowing the hyperspace mist to seep out of the braid and permeate the surrounding material in which it is embedded. Fuel Cells Information, Fuel Cells Facts, Fuel Cells Technology According to many experts, we may soon find ourselves using fuel cells to generate electrical power for all sorts of devices we use every day. A fuel cell is a device that uses a source of fuel, such as hydrogen, and an oxidant to create electricity from an electrochemical process. Much like the batteries that are found under the hoods of automobiles or in flashlights, a fuel cell converts chemical energy to electrical energy.

Quadrupling the World GDP by 2010 The solution for the political-economic problems of Africa, Argentina, Afghanistan, and other nations Editor's note: This is the second in a series of articles by financial futurists Karun Philip [KP] and Richard S. Kirby [RK]. Together in a series of books, essays and stories they are laying the foundations for a rapid redefinition of financial civilization. Their purpose is the end of poverty -- their method is making a New World of money.

Window Socket – Solar Energy Powered Socket by Kyuho Song & Boa Oh The Window Socket offers a neat way to harness solar energy and use it as a plug socket. So far we have seen solutions that act as a solar battery backup, but none as a direct plug-in. Simple in design, the plug just attaches to any window and does its job intuitively. Summary: Space Applications of Hydrogen and Fuel Cells Summary: Space Applications of Hydrogen and Fuel Cells For decades, NASA has relied upon hydrogen gas as rocket fuel to deliver crew and cargo to space. With the Centaur, Apollo and space shuttle vehicles, NASA has developed extensive experience in the safe and effective handling of hydrogen.

Possibilianism Not to be confused with Possibilism. Possibilianism is a philosophy which rejects both the diverse claims of traditional theism and the positions of certainty in strong atheism in favor of a middle, exploratory ground.[1][2][3][4][5] The term was first defined by neuroscientist David Eagleman in relation to his book of fiction Sum: Forty Tales from the Afterlives.[6] Asked whether he was an atheist or a religious person on a National Public Radio interview in February 2009, he replied "I call myself a Possibilian: I'm open to...ideas that we don't have any way of testing right now."[6] In a subsequent interview with the New York Times, Eagleman expanded on the definition: "Our ignorance of the cosmos is too vast to commit to atheism, and yet we know too much to commit to a particular religion.

How the Stock Market and Economy Really Work - Kel Kelly - Mises Daily - StumbleUpon "A growing economy consists of prices falling, not rising." The stock market does not work the way most people think. A commonly held belief — on Main Street as well as on Wall Street — is that a stock-market boom is the reflection of a progressing economy: as the economy improves, companies make more money, and their stock value rises in accordance with the increase in their intrinsic value. A major assumption underlying this belief is that consumer confidence and consequent consumer spending are drivers of economic growth. A stock-market bust, on the other hand, is held to result from a drop in consumer and business confidence and spending — due to inflation, rising oil prices, high interest rates, etc., or for no reason at all — that leads to declining business profits and rising unemployment.

Ibasei's Cappa provides hydroelectricity on a small scale The Cappa compact hydropower generator can deliver 250 W of electricity Image Gallery (4 images) Despite being the most widely used form of renewable energy worldwide, hydroelectricity is generally reserved for large-scale commercial installations built around massive dams. Japanese company Ibasei has shrunk things down and removed the need to build a dam with its Cappa compact hydropower generator – a system that's designed to be installed along a river or waterway. The basic design of the Cappa is nothing new – blades rotate as the water flows through the unit, which drives a turbine to generate electricity. However, the unit is encased in a special diffuser that is designed to increase the velocity of the water at the point where it passes over the blades, thereby increasing the unit’s electrical output.
