Solar Powered Cars

What Are Solar Powered Cars?
Solar powered cars are electric vehicles which are powered by solar energy that is obtained from solar panels on the surface of the car. Basically, photovoltaic cells then convert the sun’s energy directly into electrical energy. Solar powered cars are can operate for limited distances without the sun, but they are still not considered as a practical form of transportation.
Solar powered cars were first built by universities and manufacturers, and deve ....etc

Abstract :
A stirling engine is a heat engine that operates by cyclic compression and expansion of air or other gases (working fluid) at different temperature levels such that there is a net conversion of heat. The general cycle of a stirling engine consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle. The working fluid inside the stirling engine in this case is heated gas using solar energy from the sun.
The main components of this project are:
Stirling En ....etc

ABSTRACT

The present seminar deals with the explanation of the advantages & necessity of solar power in the present world through solar powered vehicles. Solar-powered vehicles (SPVs), such as cars, boats, bicycles, and even airplanes, use solar energy to either power an electric motor directly, and/or use solar energy to charge a battery, which powers the motor. They use an array of solar photovoltaic (PV) cells (or modules made of cells) that convert sunlight into electricity. The electricity either goes directly to an electri ....etc

Abstract
Here is a cool project about making fresh water from salt water using solar power. The apparatus is made from readily available materials, and the power source is free. How much water can the device produce, and by how much is the salt concentration reduced? Can you figure out ways to make the collection efficiency even higher? This is a great project for inventive thinkers.

Introduction
Nicholas Kinsman is interested in inventing solar-powered devices to reduce our dependence on other energy sources. He's al ....etc
