AeroVelo, University Of Toronto Team, Win Human Powered Helicopter Flight Competition - 0 views

  •  
    "human power, delivered to the craft's four rotors through the bicycle pedals he steadily pumps throughout his flight. It's that fragile machine, built by Reichert's Canadian team, which has now won a long-coveted international prize that lay unclaimed for years. The AHS Igor I. Sikorsky Human Powered Helicopter Competition was established in 1980 for the first successful controlled flight of a human powered helicopter that could reach a height of three metres while hovering for at least one minute in a 10-square-meter area."

Powered Flight Deck of the Space Shuttle Endeavour photos - 0 views

  •  
    The most complex machine ever built by mankind. Check it out. Just think, the commander of the shuttle must know ever knob, dial and gauge and know how they all interact. Mind bending! After all that they must dead-stick the landing from space at enormous speeds, hit the spot and no go-arounds. One shot only. Interior Photos of Endeavour These photos capture the Flight Deck (cockpit) of the Space Shuttle Endeavour, fully powered for one of the final times. Just a few weeks later, at 9:58am EDT on May 11, Endeavour was powered down for the final time in history. It was the last of the three space shuttles to have power. Below, other views show the mid-deck, gutted of its lockers and storage areas, and three final photos show the white room entrance in the Orbiter Processing Facility, signed by thousands over the years.

FerociousFrankie.com - OFMC Duo, Duxford Autumn Air Show 2009 - 0 views

  •  
    Duxford Spitfire and P-51 Taken at Duxford RAF and USAAC Museum in England. Two of the greatest WWII fighter planes of their era....the American P51 Mustang and the British Supermarine Spitfire. Both planes were powered by the powerful Rolls Royce Merlin engine......which emitted that wonderful sound that became known to many as 'The Sound of Freedom' during the 1940s. Such memories for those of us who were around at the time. P-51 pilot does a great job staying in his position as he has more power and is faster than the spitfire. they must have done a bit of practicing.

Climate and Earth's Energy Budget : Feature Articles - 0 views

  •  
    "The Earth's climate is a solar powered system. Globally, over the course of the year, the Earth system-land surfaces, oceans, and atmosphere-absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ice, and warms the Earth system."

Skylon Spaceplane | Interesting Engineering - 0 views

    "project to take the Skylon spaceplane into the orbit. During most of time it would be used as a normal airplane, like taking off and landing on conventional runways, but the main difference is in the power source of this aircraft. It will be powered by a Sabre engine, specially designed for its purpose. It will be working like a normal jet engine in the lower attitude, breathing in oxygen and when in higher altitude of outer space it will act as a rocket engine. So, we may call it some sort of a "hybrid engine"."

    "But as energy demand climbs, so have efforts to turn wind into a viable option for producing electricity on a large scale. Wind turbines in particular are what people think of when discussing wind power. These turbines can measure more than 400 feet (122 meters) tall and weigh in at close to 400 tons."

    "With only one operating plant globally, Rance River (as in picture), in France. The barrage method of extracting tidal energy involves building a barrage as in the case of the Rance River. The barrage turbines generate as water flows in and out the estuary bay or river. The Rance tidal power plant and the largest such installation has been working on the Rance River since 1966 with an installed (peak) power of 240 MW, and an annual production of 600 GWh. "

    "The solar cells that power solar aircraft are called photovoltaic (PV) cells. PV cells are made of materials that absorb light energy. The PV cells in most solar planes are made of silicon. Silicon is both lightweight and efficient, so it is the best choice for solar planes where the challenge is to create an aircraft light enough to fly but with enough power to get off the ground."

    "May 1888: Tesla Patents "Electric Transmission of Power" Electric power is an aspect of modern life that most of us take for granted. And while the general public associates Thomas Edison with its invention and the development of transmission processes, the methods used today are largely due to the efforts of Nikola Tesla. "

Engineering the Earth: Exploring Wind Energy - 0 views

  •  
    Wind is one important source of alternative energy. In this activity, kids create their own wind turbine and attach it to a Hot Wheels Car. Then they can use a fan to power the turbines so their cars can move! Wind is a great alternate to fuel since fuel pollutes the air and is nonrenewable. Because wind is a renewable energy source, we will never run out! However, as the girls at Girlstart discovered from testing their own cars, there are some cons to powering a car with wind.

Waste-Powered 'Poop Mobile' Unveiled By Japanese Toilet Maker TOTO (VIDEO) - 0 views

  •  
    Wastepoered Toilet Mobile - An innovative hybrid project is turning heads across Japan, as the TOTO Bike Neo, known more causally as the poop-mobile, makes a high-profile pitch for environmental responsibility. The three-wheeled bike is powered by biogas fuel made up of fertilized, purified livestock waste and gray-water, according to the International Business Times. Despite the eye-catching -- and decorative -- oversized-toilet seat, the bike does not actually run on excrement provided by the driver. "

Students claim human-powered chopper record - 0 views

  •  
    "The National Aeronautic Association has certified the July 13 record for the University of Maryland's human-powered helicopter called Gamera. It achieved liftoff and hovered for 11.4 seconds, setting U.S. records for flight duration and for flight duration by a female pilot. (Watch a video of the flight.). It was designed and built by graduate and undergraduate students at the University of Maryland's A. James Clark School of Engineering and piloted by biology student Judy Wexler. "

First Flight: the Early Aviators - Disciples of Flight - 0 views

    • docderz
       
      Solid overview of the early history of aviation, leading up to the Wright Brothers.
  • The dream of flying is as old as humankind itself. Throughout our history, we have struggled to achieve flight. And it wasn’t until fairly recently in our history that we achieved the first flight. We started with balloons, followed with gliders, and eventually developed powered aircraft. The story of this achievement is a fascinating one, with many players such as the Wright Brothers being well established. However, their historic first flight at Kitty Hawk in 1903 may not have actually been the first powered flight. In this three part series, Disciples of Flight is going to look at the question of who achieved the first flight with a powered aircraft. In part one, First Flight: The Early Aviators, we will look at the development of flight leading up to the Wright Brothers. Part two, First Flight: the Wright Brothers, will give a brief history of the brothers, and cover their first flight. And part three, First Flight: Gustave Whitehead, will cover the bold claims of Gustave Whitehead, and others, to first flight.
