A human-powered rocket is a steam powered-rocket that uses steam instead of rocket fuel for thrust,the human-powered element comes from the fact that the heat to produce the steam comes from human beings. Let me explain how it would work. The lower part of the rocket is basically a large water tank, and boiler. The water tank is filled with several thousand gallons of water. The entire rocket, with its water tank,boiler,and other equipment may be more than 200 feet high, roughly as high as a twenty-story building. A re-entry vehicle sits on top of the rocket. This re-entry vehicle is approximately 100 feet high,and has wings like a space shuttle. The bottom of the re-entry vehicle is covered with heat-resistant ceramic tiles, like the space shuttle, so it resembles the space shuttle. Although the re-entry vehicle looks like a space shuttle on the outside,it would look very different on the inside. There are seats for 150 astronauts inside the re-entry vehicle. There is a set of pedals on the floor in front of each seat. When the astronaut sits in his seat, he puts his feet on the pedals,and pedals as if he were pedaling a bicycle. The pedals are connected to an electrical generator that is located under the floor of the crew compartment. When an astronaut pedals, the energy produced by his leg muscles is converted into electricity. The electricity produced by all the astronauts, collectively goes through wires to the water tank. The electricity is then used to heat the water in the water tank, so the water will be converted into steam. Since the water tank is extremely large and contains thousands of gallons of water,it cannot be converted into steam quickly. The astronauts inside the re-entry vehicle have to pedal for three days until they build up enough steam for the rocket to take off. To do this, they are split into two groups. One group is called group A,the other group is called group B. Group A pedals for twelve hours,while group B sleeps for twelve hours,then they trade places,so group A sleeps for twelve hours, while group B pedals for twelve hours. They do this for approximately three days until the thousand of gallons of water in the water tank has been turned into steam. Then, the pilot of the vehicle tells the 150 astronauts that they must all pedal at the same time. When they all pedal at the same time, the pilot pushes a button that causes the steam exhaust valve at the bottom of the rocket to be opened. when the valve is opened, the steam can Category:Home › Other • Pomegranates: A newly discovered superfood • Where did the joke why did the chicken cross the road come from and why is it funny? • Can mothers diagnosed with bipolar disorder make good parents? • Spiritual evolution of human consciousness • Tips for getting a college basketball scholarship • Living with Pseudotumor cerebri (PTC) • Caring for the caregiver • Technologys impact on society
