1. INTRODUCTION Cars are immensely complicated machines, but when you get down to it, they do an incredibly simple job. Most of the complex stuff in a car is dedicated to turning wheels, which grip the road to pull the car body and passengers along. The steering system tilts the wheels side to side to turn the car, and brake and acceleration systems control the speed of the wheels. Given that the overall function of a car is so basic (it just needs to provide rotary motion to wheels), it seems a little strange that almost all cars have the same collection of complex devices crammed under the hood and the same general mass of mechanical and hydraulic linkages running throughout. Why do cars necessarily need ...
ABSTRACT The lack of clean drinking water is a problem that plagues many areas of the world today. Approximately 884 million people suffer each day from insufficient quantities of clean, drinkable water. Most of the current technologies available to combat this problem are expensive and consume too much power to be effective in rural regions of the planet. The solutions that do not consume an excess of power generally require expensive and time consuming filter maintenance. The use of chemical processing mechanisms of purification is an affordable solution, but it has been known to be hazardous if used improperly. With the idea of low cost and sustainability in mind, we plan to develop a water filtration system that will take advantage of natural energy in order to power a water purification system. Water will enter the system, where it will flow through a sediment filter and then be processed by a UV purifier. By using both standard sed...
