Alien Planet Kepler-452b Our Milky Way Galaxy is filled with exoplanets—statistically speaking at least one for each of the hundreds of billions of stars in the galaxy. An astonishing finding is that the most common type of planet in our galaxy are those with sizes between those of Earth and Neptune. This has become a new class of planet that is neither terrestrial nor giant and one without an accepted theory for its formation. Planets on orbits between the hot planets and the cold planets are also

Harnessing of Solar Energy: Photosynthesis versus Semiconductor Based Solar Cell Photosynthesis and semiconductor-based solar cells are both used to harness solar energy from the sun – photosynthesis for plants and semiconductor based solar cells for human beings. Photosynthesis consists of light reactions and dark reactions. It is a process in which carbon dioxide (CO2)‚ water (H2O) and light energy are utilized to synthesize an energy-rich carbohydrate like glucose (C6H12O6) and to produce

with his friends invented an innovative bird feeder that worked on solar power. The feeder used a small solar panel in its roof to build an electric charge. The Solar feeder’s purpose is to use the mild electric shock it generates to repel the squirrels‚ preventing them from stealing the bird seed or damaging the feeder itself. In a typical product-driven approach‚ Bo and his friends started SDI‚ Inc. to produce and promote the solar feeder without having done any marketing plan. After several years

for Research Essay The topic for my research essay is “Solar Power Cars“. My curiosity grew towards solar energy since the first time I heard about it‚ and over the time‚ my interest has developed‚ while coming across different and wonderful applications of such a never ending energy source. I have also been passionate about motor car designs since childhood‚ and my curiosity to find out about the consequences of combining solar energy with motor cars‚ led me to choose my topic.

2/24/09) Solar energy is the cleanest‚ most abundant‚ renewable energy source available which described as the sun’s rays that reach the earth and can then be converted into either thermal (heat) or electricity. Solar energy converted into heat can be used to: heat water for use in homes and buildings and heat spaces. Solar energy can be converted into electricity in two ways: 1) photovoltaic cells; and 2) solar thermal plants (also known as concentrated solar power or CSP)‚ which are essentially

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

Solar car design Originally published on Solar Love. Generally speaking‚ I don’t think solar-powered cars are very practical. They are fun and do highlight how far we’ve come. They may help to advance certain electric car technologies and designs. However‚ except for certain niche situations (like a hospital car for rural Zimbabwe)‚ they have serious limitations. For one‚ solar panels aren’t cheap — risking their destruction or damage in a car accident doesn’t seem wise. Secondly‚ the sun
