Solar Powered Cars By SolarCars on October 25‚ 2009 Cars that run on fossil fuels are still standard‚ but many would like to replace those diesel or gas engines with alternative fuels. One promising possibility is to develop solar powered cars. Although this is not yet a reality‚ prototypes have been built and proven to be functional and now many researchers are trying to find ways of using solar energy to power cars. Solar powered cars would have many advantages over those that run on fossil

astronauts when an amount of radiation gets through the walls of a space shuttle or station and enters the body. Solar radiation usually affects astronauts walking in space‚ outside of their space shuttles‚ but sometimes it can even affect the people on Earth‚ causing electricity failures. Many people - astronauts mostly- fear the consequences of solar radiation‚ due to the fact that solar radiation can cause dangerous effects to one’s health. Even though sometimes the effects are so minor‚ you can

SOLAR ENERGY PRODUCTION IN INDIA Coming specifically to the land of much sun‚ heat and humidity as well as persistent power shortages‚ overdependence on coal (52%) and huge oil and gas imports‚ solar energy production in India remains appallingly low. This is made evident by the minimal range of solar energy products in India. Solar lighting (solar lamps‚ street lights)‚ rural electrification‚ solar water heaters‚ solar cookers and PV pumps sum up the measly range of solar energy products

Stars A star is a massive‚ luminous sphere of plasma held together by gravity. The nearest star to Earth is the Sun‚ which is the source of most of the energy on the planet. Solar System The Solar System consists of the Sun and its planetary system of eight planets‚ their moons‚ and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system’s mass is in the Sun‚ with most of the remaining mass contained

The Benefits of Solar Energy Melissa Strayer University English 215 July 20‚ 2012 The Benefits of Solar Energy Solar energy represents the future of a clean earth in days to come; it also represents the clean air that our children and their children will breathe. We constantly have to worry about pollutants in our air from all of the many harmful chemicals being thrown into the air by fossil fuels; we never stop to think about how this will affect our children‚ and it’s time that we start

SOLAR SYSTEM About 5 Billion years ago‚ y There was no Sun‚ no Earth& no Moon y Only cosmic dust and gasses drifted in the darkness of space SOLAR SYSTEM THEORY The solar system was formed by a slowly spinning cloud of gas and cosmic dust‚ gradually the cloud began to spin faster and faster this formed a large spinning whirl at the centre and smaller whirls surrounding it at various distances. SOLAR SYSTEM THEORY The huge and heavy centre became hot enough to start thermo nuclear

Solar water disinfection Solar water disinfection is a type of water purification system that uses solar energy in order to make contaminated water safe to drink. This is done by eliminating contagious biological organisms such as bacteria‚ viruses‚ protozoa and worms. This process can only be taken place on biological agents non-biological agents such as toxic chemicals or heavy metals disinfection may not make all kinds of water safe to drink. Therefore additional steps away from disinfection
