Solar Powered Traffic Light Solar traffic lights are signaling devices powered by solar panels positioned at road intersections‚ pedestrian crossings and other locations to control the flows of traffic. They assign the right of way to road users by the use of lights in standard colors (red - amber/yellow - green)‚ using a universal color code (and a precise sequence to enable comprehension by those who are color blind). Most of the solar traffic lights have battery back-up for functioning during

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

Proper understanding of each of these discoveries and theories is important when learning about our universe. Planetary Accretion Planetary accretion has two main theories on how the planets in our solar system were formed. The first of the two is the Solar Nebular Disk Model; this is where our Solar System’s planets started out as small pieces and started to collide together‚ uniting into bigger pieces and this kept happening until they became planetesimals. Once they were planetesimals‚ they crashed

Renewable energy Renewable energy is any source of energy that doesn ’t consume the finite resources of the Earth and can be easily and quickly replenished. At present only a small proportion of the world ’s energy needs come from alternative and renewable energy sources. These exist in many forms including Solar Thermal‚ Photovoltaics‚ Wind‚ Hydro‚ Tidal/Wave and Bioenergy (including Biomass‚ Biogas and Biofuels). As with fossil fuels the sun ’s energy is the ultimate source of these energies.
