tuhin4u (Unstopable Lover + Mariana World DIAMOND member): Earth's land surface, oceans and atmosphere absorb solar radiation, and this raises their temperature. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation 0r convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and anti-cyclones. *06-10-14 - 05:30:44
tuhin4u (Unstopable Lover + Mariana World DIAMOND member): Sunlight absorbed by the oceans and land masses keeps the surface at an average temperature of 14 °C. By photosynthesis green plants convert solar energy into chemical energy, which produces food, wood and the biomass from which fossil fuels are derived. *06-10-14 - 05:31:56
tuhin4u (Unstopable Lover + Mariana World DIAMOND member): The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. In 2002, this was more energy in one hour than the world used in one year. Photosynthesis captures approximately 3,000 EJ per year in biomass. The technical potential available from biomass is from 100–300 EJ/ year. *06-10-14 - 05:34:27
tuhin4u (Unstopable Lover + Mariana World DIAMOND member): The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined, Solar energy can be harnessed at different levels around the world, mostly depending on distance from the equator. *06-10-14 - 05:35:46
tuhin4u (Unstopable Lover + Mariana World DIAMOND member): In 1908 Shuman formed the Sun Power Company with the intent of building larger solar power plants. He, along with his technical advisor A.S.E. Ackermann and British physicist Sir Charles Vernon Boys, developed an improved system using mirrors to reflect solar energy upon collector boxes, increasing heating capacity to the extent that water could now be used instead of ether. Shuman then constructed a full-scale steam engine powered by low- pressure water, enabling him to patent the entire solar engine system by 1912. *06-10-14 - 05:37:51
