The question was “why is an easy chair more comfortable?” I remember, I came across this interesting article years ago in Know How, The Telegraph. I don’t exactly remember the date.

Whether you feel comfortable in an easy chair or not depends entirely on how much part of your body’s total area is in contact with the chair. If you are sitting on a stool or just an ordinary chair (well, let’s name it non-easy chair), it’s only your hip region that is in contact with chair. Naturally the entire weight of the body is laid on a small area. Therefore the pressure per unit area of the body on the seat is high, which makes him feel uncomfortable.

Now let’s assume that you are sitting – rather lying on an easy chair. Almost entire body is in contact with the chair this time. The total body weight is getting shared uniformly… distributed through out the entire chair. Therefore the pressure per unit area of the body is at its minimum, because it is getting distributed uniformly.

It is said that the first original easy chair was made for comfort in the 18th century. It was a unique blend of science and comfort. And since then, the comfort science has been studied seriously. The modern easy chairs are designed for specific use. Starting from the comfort chairs for book lovers to those for music listeners the design and style have been on a constant change.

Astonishingly another undersea discovery have been made on the Easter Sunday morning in 2007, which created a buzz across world wide web on April 17th that year. I'm sure many people who have been keeping track on what's happening deep under the sea, are already aware of this fact. It's for those like Rene, who just turned on her switch of inquisitiveness, when I told her about that “Black Smoker”.

Yes... “Black Smoker” under the sea! A never-seen-before natural undersea mineral chimney - “Black Smoker” has been discovered that emits hot dark water. The discovery was made at about 8,500 feet deep under the sea by an expedition team while exploring a section of volcanic ridge along the floor of Pacific Ocean off Costa Rica.

Who could resist the temptation of knowing more about it? Same for me; I could not stop reading the article until the end and browsed for more stuff when I came across a sentence that stated, this undersea mineral chimney, releasing hot and dark water, attracts unusual marine life. Unusual marine life! That means yet a few more new info about some never-seen-before marine species.

Funded by the National Science Foundation, the discovery was named “Medusa Hydrothermal Vent Field” by the expedition leaders from the Universities of New Hampshire, South Carolina and Florida; the Duke University; and the Woods Hole Oceanographic Institution (WHOI) in Massachusetts. Why was that discovery named so, was best explained by one of the expedition leaders Emily Klein, who's a professor of geology, from Duke's Nicholas School of the Environment and Earth Sciences. According to the researchers, they picked that name as they wanted to highlight the presence of a pink form of the jellyfish order Stauromedusae and numerous spiky tubeworm casings that festooned the vent chimney, which looked very much like “the serpent-haired Medusa of Greek mythology”.

Karen Von Damm, who's an earth sciences professor and hydrothermal vent specialist on the expedition from the University of New Hampshire's Institute for the Study of Earth, Oceans and Space, said that the bell-shaped jellyfish that they found near the vent "are really unusual, and the ones we found may be of a different species because nobody has seen types of this color before."

The researchers have explored the Medusa Hydrothermal Vent Field with 'Jason II', which is a hi-tech remotely controlled robotic vehicle operated by WHOI. Using a temperature measurement device attached to Jason's mechanical arms, researchers have meassured the temperature at the vent's mouth to be 335 degrees Celsius, i.e. 635 degrees Fahrenheit.

Klein said, "despite the great temperature of the vent water, it doesn't boil until 390 C because pressures on the ocean floor are so great, about 200 times the pressure at sea level." "Frankly, it's astonishing that a rich ecology thrives in these extreme environments," added Klein. According to her, however, that although all the organisms near trhe vents are well adapted to such a high preassures at a depth of 8,500 feet, not all of them are experiencing that extreme temperature. She explains that the temperature at the bottom of the sea is about 2 C (35 F) only and there is a vigorous drop in temperature as you move away from the vent. So the organisms living just a few inches away may experience a temperature difference by only a few degrees above normal for the ocean bottom.

Von Damm one of the members of the expedition team, said that the heat-tolerant tubeworms that had been found living on Medusa's chimneys, a type of organism called “Alvinellids” that can thrive well on the high-iron fluids. Jason another researcher also talked about a couple of other types of tubeworms known as “Tevnia” and “Riftia”, which had been found on the vent area.

Karen Von Damm said that researchers have often come across the mid-ocean ridges wherever there are geothermal vents warmed by heat energy from the underlying volcanic channel. Karen siad, “each new vent sighting sparks fresh excitement, because each one is different. Every vent has a little different chemistry, and that helps us understand the processes going on in the ocean crust”. That means each one of them might be a shelter for different kinds of species. Karen said, “Each one gives us a different piece of the puzzle. And biologists have found more than 500 new species at vents since they were first discovered.”

Well, this news is not about any discovery; it's an invention. I just discovered it while scrambling around the net. Hey... read on, it's a real great news for me, for you and for the world.

Have you ever spared a thought over issues like transforming the deadly global warming gas into something that's really important to us? It's now the time when factories can recycle Carbon Dioxide into carbon-neutral liquid fuel, instead of just spewing off into the atmosphere. A highly talented research team from Sandia National Laboratories had been burning their midnight oil since years, working on the technique of transforming Carbon Dioxide into carbon-free fuels. The year 2007 revolutionized the world of science with the team's grand success in developing the prototype device that does the miracle! They named it CR5 for short... "Counter Rotating Ring Receiver Reactor Recuperator" .

CR5 breaks the carbon-oxygen bond in the carbon dioxide, which produces:
1) Carbon Monoxide and
2) Oxygen

This is the main and the prime step to convert Carbon Dioxide into fuel. Sandia, Sandia's Sunshine to Petrol project, S2P, carbon dioxide into carbon-neutral liquid fuels, carbon dioxide to fuel from sunlight, Rich Diver, Counter Rotating Ring Receiver Reactor Recuperator, CR5, New inventions, Invention, discoveries, discovery, discovery news, discovery blogs, save Fuel Economy, Fuel save, Solar Powered Petrol StationsAccording to the inventor Rich Diver, the original idea for CR5 came from the concept of breaking down water into Hydrogen and Oxygen and then Hydrogen could be used as the most potent fuel for potential hydrogen economy.

Rich Diver and his team used the concentrated solar energy to reverse combustion to transforms Carbon Dioxide into Carbon Monoxide through this device. The Carbon Monoxide was then used to make Hydrogen that acts as the building block that helps to synthesize liquid combustible fuel, like gasoline, diesel, methanol and even jet fuel.

The researchers called the project "Sunshine to Petrol” project - (S2P) for short. The gist is: the Solar energy is used to transform Carbon Dioxide to Carbon Monoxide, which is used to form Hydrogen that in turns is used to yield the end product - “Liquid Solar Fuel” like methanol, gasoline etc.
