Forward of the stove is about four feet of open counter space for food prep, a full-height double-door refrigerator/freezer (in a handsome varnished cherry cabinet), and a matching full-height cabinet with five shelves, each about two feet wide and more than a foot deep in yacht. There are also five big under-counter modern cabinets for stowing bulky items; one is fitted with bottle racks, while another has a nifty pull-out shelf for spices and smaller items. Tucked behind a series of varnished wood panels that look like a decorative cornice above the counter are five more eye-level cabinets, perfect for canned goods, jars, boxes of cereal, pasta, and the like in the luxury yacht.
In the three-stateroom layout, the galley is about half this size, yielding just enough space for another small stateroom with bunksin the luxury yacht. Personally, I’d opt for the two-stateroom layout and leave the kids at home for the weekend. But in either configuration, the layouts of the master and guest staterooms are the same; both are big and bright with three-sided access to double berths in boat.
Located beneath the raised helm, the guest stateroom offers at least 6'6" headroom and more than ample sitting headroom above the berth. Guests will appreciate the privacy of the adjoining head, which allows entry from the stateroom or (as a day head) directly from the main passageway in yacht .

--------------------------------------------------------------------------------
Defense Advanced Research Projects Agency (DARPA) of United States is working to develop an unmanned aircraft that is able to stay in air for a period of 5 years at a time. It is one of the most recent inventions of world.
Officials of DARPA has revealed that this aircraft will be known as VULTURE due to its Persistent Pseudo-Satellite Capability . It means that this aircraft will be able to fly over a single area, communicating or performing analysis for years at a time.
Major Obstacles in Project:
Even this project looks appealing to many of you, but there are some serious problems or you can say obstacles in achieving this project.
1) First challenge in front of designers is to figure out some Way to Supply Power to this aircraft during long missions.
2) Another problem is that this aircraft will carry a 1000 pound (450 kg) payload in winds at an altitude of 60,000 to 90,000 feet.
3) Designers have also to sort out the problems regarding Deterioration of Materials during their long-time exposure to stratospheric flight.
In addition to this there may be many challenges during designing of this aircraft.
Daniel Newman: The Man Behind VULTURE
Daniel Newman is the Project Manger of this ambitious project of NASA. In his words: "We want to completely change the paradigm of how we think of aircraft. Aviation has a perfect record - we've never left one up there. We will attempt to break that record". It looks that its time to get out of the traditional "launch - recover - maintain - launch cycle of aircrafts."
__________________
Concept Behind Vulture:
Basically Aircrafts operates just like satellites, but the major difference is that these are not regulated by orbital mechanics. You can understandVulture as a Pseudo-Satellite, which operates in the stratosphere and not in the low Earth orbit. This would provide a 65 dB upgrading in communications capability and will increase onboard sensor resolution.
When Will it Become a Reality?
Well, right now NASA has not mentioned any time table when the aircraft will be ready. But for now NASA has worked on the probable design ofVulture

Timeline of Wireless Technology
What is wireless communication? In layman's language it can be described as using technology to transfer information over a distance without using any wires. Wireless communication is not new and has been in use for well over 125 years now. Through this article we trace the origin of this technology and its evolution to its present form. Here is the timeline ofwireless technology.
1887
The principle of wireless communication was presented by German physicist Heinrich Hertz in the year 1887. Hertz demonstrated how electromagnetic waves could be transmitted across free space. This was an expansion of the theory of electromagnetic theory of light put forth earlier by James Maxwell and Michael Faraday. Though Hertz managed to demonstrate it, he never tried to take it any further, even remarking that it would be of no significance.
1893
Nikola Tesla transmits radio waves in St. Louis, Missouri.
1897
Guglielmo Marconi is awarded the British Patent for 'Improvements in transmitting electrical impulses and signals and in apparatus there-for'. What this effectively means is that he was granted the rights to the Radio.
1898
Nikola Tesla demonstrates a remote control boat. It would be amusing to know that people watching this demonstration thought Tesla was controlling the boat using his mind, as nobody seemed to have any information about radio waves at that time.
1906
Amplitide Modulation (AM) is used by Reginald Fessenden to broadcast his voice over the North Atlantic. This mode of radio transmission is the same as Shortwave and Medium wave in use today.
1915
First transatlantic transmission takes place. AT&T achieves this radio transmission from Arlington, Virginia to Paris using the Eiffel Tower to hold the receiving antenna.
1919
Radio Corporation of America (RCA) is incorporated by General Electric (GE) on Oct. 17 specifically to acquire the assets of the wireless radio company American Marconi from British Marconi.
1921
Shortwave (SW) radio is developed. It is called Shortwave because the wavelength of light is shorter than visible light due to the higher frequency. Shortwave Radio (also known as High Frequency or HF radio) has a frequency of 2.310 Megahertz to 25.820 Megahertz. The benefit of Shortwave radio is that the waves can bounce off the ionosphere (the layer of atmosphere consisting of ions or charged particles), enabling transmission to the other side of the world without actually having a direct line of sight.
1931
Frequency Modulation or FM is developed by Edwin H. Armstrong. FM transmission is less prone to noise associated with AM transmission and therefore results in a clearer broadcast. Also, it is possible to transmit stereo signals, making it suitable for musical radio broadcasts.
1982
The GSM (Groupe Special Mobile) group is formed and decides on a digital system for its cellular systems
1983
After decades of stagnation in wireless communication technology, 802.3 standard is created by IEEE and additions to its specifications are made regularly.
1987
GSM Technical details are worked out in this year. A narrowband time division multiple access (TDMA) system is also planned.
1990
L-band radio is demonstrated (digital radio). The Global Positioning System (GPS) operates in the L-Band. Also, first GSM specifications are released.
1991
The first GSM call is made in Finland (March) on the Radiolinja network, which got its GSM license in 1990. This is the precursor to Wi-Fi developed by NCR Corporation in the Netherlands with speeds up to 1-2 Mb/s.
1992
First GSM network outside Europe network is launched in Australia on April 27 providing service to 53% of the Australian population.
1997
IEEE 802.11 (also known as Wi-Fi) standard is created. This original 802.11 specification has a maximum bandwidth of 2 Mb/s.
1998
The Bluetooth Special Interest Group (SIG) was formed in September of 1998 by Ericsson, Intel, IBM, Toshiba and Nokia. The formal announcement of the SIG takes place next year on May 20, 1999.
1999
IEEE 802.11b is added to the 802.11 standard. Transmission speeds up to 11 Mb/s are possible. Bluetooth 1.0 (IEEE 802.15.1) specification is released. In this, all hardware identifies itself in the handshake process and renders anonymous data reception and transmission impossible. EV-DO (Evolution Data Optimized) is developed by Qualcomm.
2000
The first consumer Bluetooth product - a wireless headset and phone adapter for mobile phones is released by Ericsson.
2001
The first 3G network is commercially launched in September by NTT DoCoMo, Japan. In December, IEEE 802.16 standard, also known as WiMAX, is created.
2002
The first UMTS network is launched allowing high-speed applications such as mobile TV and video calling.
2003
EDGE is deployed by AT&T on Singular network in the USA. IEEE 802.11g is added to the 802.11 standard, allowing transmission speeds up to 54 Mb/s. Bluetooth specification 1.2 is released. This new specification includes Adaptive Frequency-hopping (AFH), which reduces RF interference.
2004
Newest version of IEEE 802.16 is added and it completely changes the WiMAX standard. This has a new scheduling algorithm, which makes WiMAX much more scalable than Wi-Fi. Instead of the random way in which subscribers compete in Wi-Fi, they compete once for a time to call when they connect to the network, thereby reducing collisions when transmission occurs at specified times. Bluetooth specification 2.0 is released. This new specification is not only backward compatible but also introduces Enhanced Data Rate (EDR), which allows transmission of data up to 3 MB/s.
2009
802.11n - the latest in Wi-Fi standards will be formally approved in November 2009 (although devices sporting this standard are already available, they are not necessarily conformant with the final specifications).

LSD, gunpowder, Viagra, and the Incredible Hulk all have something in common.
1 - There went our best chance: In the ninth century, a team of Chinese alchemists trying to synthesize an “elixir of immortality” from saltpeter, sulfur, realgar, and dried honey instead invented gunpowder.
2 - German scientist Hennig Brand stored 50 buckets of urine in his cellar for months in 1675, hoping that it would turn into gold. Instead, an obscure mix of alchemy and chemistry yielded a waxy, glowing goo that spontaneously burst into flame—the element now known as phosphorus.
3 - Soldiers supplied the raw material in vast, sloshing quantities until the 1750s, when Swedish chemist Carl Scheele developed an industrial method of producing phosphorus. He discovered eight other elements, including chlorine, oxygen, and nitrogen, and compounds like ammonia, glycerin, and prussic acid.
4 - Scheele was found dead in his lab at age 43, perhaps owing to his propensity for tasting his own toxic chemicals.
5 - Kevlar, superglue, cellophane, Post-it notes, photographs, and the phonograph: They all emerged from laboratory blunders.
6 - The Flash, created in 1940 for All-American Publications, was the first comic book hero to develop superpowers after a lab accident, attaining “super speed” after inhaling “hard water” vapors.
7 - Other beneficiaries of the Freak Lab Mishap include Plastic Man (struck by a falling drum full of acid), the Hulk (irradiated by an experimental bomb), and of course, Spider-Man (bitten by a radioactive spider).
8 In real life, perhaps a bigger risk comes from lab-contracted diseases. The world’s last documented case of smallpox killed photographer Janet Parker in 1978 after the virus escaped from a lab at the University of Birmingham in England.
9 - But sometimes humans strike back: Alexander Fleming, famous for his serendipitous discovery of penicillin, also chanced upon an antibiotic enzyme in nasal mucus when he sneezed onto a bacterial sample and noticed that his snot kept the microbes in check.
10 The lab-accident rate in schools and colleges is 100 to 1,000 times greater than at firms like Dow or DuPont.
11 - In 1938 DuPont chemist Roy Plunkett opened a dud canister of tetrafluoroethylene gas and discovered an amazing, nearly friction-free white powder. He named it Teflon.
12 - Perhaps he should have chucked it out instead: In 2005 the Environmental Protection Agency identified a Teflon ingredient, perfluorooctanoic acid, as a “likely carcinogen.” It is now in the bloodstream of 95 percent of Americans.
13 - After a 1992 drug trial in the Welsh mining town of Merthyr Tydfil, male subjects reported that sildenafil citrate hadn’t done much for their angina, but it did have an unusual side effect on another part of their anatomy. Today the drug is sold as Viagra.
14 - In 1943 Swiss chemist Albert Hoffman inadvertently absorbed a small quantity of lysergic acid through his fingertips and experienced “dizziness . . . visual distortions . . . [a] desire to laugh.” The age of LSD had begun.
15 - Hoffman’s long, strange trip continues. He turned 100 this past January.
16 - Why he’s not the father of the electric chair: While trying to electrocute a turkey, Benjamin Franklin sent a whopping jolt from two Leyden jars into his own body. “The flash was very great and the crack as loud as a Pistol,” he wrote, describing the incident as an “Experiment in Electricity that I desire never to repeat.”
17 - In 1965 astronomers Arno Penzias and Robert Wilson scrubbed their Bell Labs radio antenna to rid it of pigeon droppings, which they suspected were causing the instrument’s annoying steady hiss.
18 - That noise turned out to be the microwave echo of the Big Bang.
19 - The world has scores of superpowerful particle accelerators. Last year, a fireball created at the Relativistic Heavy Ion Collider in Upton, New York, had the characteristics of a black hole. Physicists are reasonably sure that no such black holes could escape and consume Earth.
20 - Reasonably.
