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

HISTORY OF SOLAR ENERGY Jake Tutorow Indiana Institute of Technology Fort Wayne‚ IN Abstract: The purpose of this paper is to explain the history of solar energy as well as the difficulties faced in acquiring government support and investments for infrastructure and technological gains. The history of solar energy is broken into five distinct categories: Earth energy‚ the ancient solar age‚ the modern solar age‚ solar in the 1950s‚ solar today‚ and agriculture. Earth energy focuses on the understanding

to Congress‚ 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

ERAST programme develops pilotless solar powered airplane technology. The HELIOS construction is based upon its predecessors like NASA’s solar plane Pathfinder‚ which was successfully tested a few years prior to HELIOS. Due to its speed HELIOS was able to fly over the same spot for days or weeks‚ therefore‚ in the future such aircrafts could

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
