Pardes Del Sol- Team Name Michael Silverman –Student #1 Pardes Del Sol Abstract Welcome to Pardes Del Sol, the city of the future. Our city is unique due to where it is situated. Pardes Del Sol is the first city to be built inside a mesa. This unique location affords our citizens protection from the fierce heat of Arizona, lowers heating and air conditioning bills, and provides a strong infrastructure on which to build a city. Pardes Del Sol provides its citizens with everything they could ever require. State-of-the-art health care facilities enable our citizens to lead long, happy and productive lives. Education for citizens is first rate, giving them the opportunity for lifelong learning. Crime is virtually non-existent due to our policy of having a police officer on every corner. Pardes Del Sol is a city that can survive on its own. We grow our own food by way of hydroponics. Hydroponics is the ideal solution for our city. It solves the need for farm land to grow crops and it is a wonderful way to recycle water. Our hydroponics system uses recycled water to grow our abundant food supply. Next, after the water has been used for hydroponics, it is sent to our filtration and sanitation plant for cleaning. Then the water is reused as drinking water. Our city powers itself by way of extremely efficient solar panels. The entire roof of the mesa is covered with these panels. Thanks to the fact that Arizona receives over 200 days of sunshine a year, we are able to capture that energy and power our entire city. In case it is partly cloudy or rainy, our city contains giant batteries that store any unused solar energy that our solar panels collect every day. One of the city’s challenges is the requirement of water. Our city imports its water from the Colorado River. This provides our citizens with a plentiful supply of fresh, clean water. Pardes Del Sol is the city of the future. It has everything a citizen of a growing metropolis could want. Pardes Del Sol means, “orchard of the sun” and if our city’s name stands strong, our citizens have a very bright future in front of them.

Pardes Del Sol- Team Name Michael Silverman –Student #1 The Aggregate Elevator The ideal city of the future, Pardes Del Sol, is located within the rocky mesas near Sedona, Arizona. In tomorrow’s world, transportation will become one of our biggest challenges due to increased population and movement needs. Elevators have changed the design of inner-building transportation. Elevators have made it possible for people to travel with ease and efficiency vertically within a structure. We believe that modern elevator systems, though effective, will not be reliable enough to handle the future requirements. The essential requirements; capacity, speed, and reliability are important factors in our elevator. Elevator capacity and speed will become crucial because of the increasing population and the need for dependable transportation between Pardes Del Sol’s inner-mesa facilities. Our idea is economical, efficient, and has a maximum capacity of 750 people, each person having 2.5 square feet of standing room. Our transportation system will revolutionize the transportation of citizens in our city, and cities in similar geographical conditions. We have taken the proficiency of the elevator to a whole new level. Our elevator system abandons the old cable and counterweight system, and adopts an entirely new system. This system uses water pressure and a low friction aggregate called NP3™, a mixture of nickel and the polymer called Teflon®. The elevator car is rectangular, allowing water to exert maximum pressure on any given side of the car. The car contains three levels, each level 25x25x10 feet (1875sqft). This makes the elevator car’s dimensions 25x25x30, almost cubical. When the elevator stops, each level stops on a different floor, and has four doors for entering and exiting. It is capable of horizontal and vertical movement, enabling this elevator to travel virtually anywhere inside the mesas within which our city is located. Our elevators travel through tubes inside our mesa, powered by water pressure. As pumps release water into the elevator’s intricate system of pipes, strong doors block off any other possible routes except for the chosen one. This exerts greater pressure on the elevator car, sliding it smoothly along the NP3™ coated surface of the pipes, to its destination, where it is then secured and immobilized by powerful magnetic clamps. Now, only the obstacle of friction remains, and our chosen aggregate, NP3™, comes into use. In order to create this futuristic system of transportation, we have expanded the classic definition of aggregate beyond simple materials like sand and rock. We believe that in the future aggregates will be made of more complex materials; hence NP3™ is our chosen aggregate. The nickel used in NP3™ is imported to our city, where it is purified using through an electrolytic process. Collected and stored in designated facilities, it is combined with Teflon® in order to make our chosen aggregate, NP3™. NP3™ has military and aerospace applications, and has uses as diverse as medical pans, go-cart pistons, and even potato chip chutes. This mixture takes advantage of the low friction and water resistance of Teflon®, and the strength of nickel. NP3™’s sliding coefficient of friction is 0.17 to 0.21 dry, about one-third that of steel, and one-eighth that of aluminum. NP3™ was developed about twenty years ago by the Robar Companies. By coating both the elevator car and the pipes through which it travels, we have reduced friction drastically creating resistance to much potential water damage, e.g. wear and water corrosion. This greatly lessens the chances of our elevator inflicting environmental damage. As our elevator system relies on a futuristic aggregate, our engineering discipline is material engineering, which focuses on the branch of engineering that covers materials and their uses. This was essential in the choosing of our aggregate and its application. Thanks to our system’s simple water powered transportation, we have ensured its reliability. Speed may easily be adjusted by varying the pump’s pressure. Water used in the water pumps is continuously recycled. Also, our enclosed water system eliminates inner-mesa evaporation. This makes our idea cost effective and well suited for the geographical conditions. In conclusion, the use of water pressure and our strong low friction aggregate has enabled us to create a dependable, economical, and efficient means of transportation for the future.
