Solar power

Renewable Energy * Wind * Solar * Geothermal * Biomass * Hydroelectric Wind Energy Wind Energy is an effect of the sun 's uneven heating of the atmosphere. Wind energy is commonly harnessed by turbines. Wind is formed when warm air expands and rises up, while cold air condenses and sinks. Wind energy can be used to power boats or even charge a battery. Although, it 's almost a perfect choice, it has its setbacks. The generators need a lot of land in order to function properly and if…

Photovoltaic cells produce direct current flow of electricity that is proportional to the amount of solar radiation hitting the cell. This is possible through the photoelectric effect, where light penetrates a surface and emits electrons. A standard silicon based photovoltaic cell will have a thin, negatively charged phosphorus-doped silicon wafer on top…

Australia gets it's power is mainly from 7 different technology forms. One is wind power. They whole use turbines to catch the wind and transfer it to power. Another way is solar. They would use solar power panels to turn sun rays into power. There are actually two different types of solar panels. One is called a solar PV that just goes on the roof or a yard to generate enough power for the house. Another is called a CSP solar panel. This panel stretches across a plain and gives enough power for…

existential source of power which human beings have harnessed through technology in order to progress and evolve. It is fair to note that energy is quintessential to every action and reaction occurring in the universe at all times. Furthermore, the law of conservation of energy states that energy cannot be created nor destroyed but can be transferred between different forms and states and even between objects. The transfer and application of energy to technology is a power human beings have been…

Solar is still expensive and the normal consumer would have to make a large investment to be able to obtain the amount of panels needed to make a difference in the consumption of their household. Many people with today’s economy cannot afford this option. Also electric vehicles are another option to lower emissions created by fuel powered cars and possibly in the future we will see more electric cars with homes run by solar power. Technology is always…

minimize losses [7]. Power conversion efficiency is defined as the ratio of electrical power output from the cell to the power of the sunlight striking the surface of the cell. This can be visualized as the ratio of areas under the absorbance spectra and AM1.5G sunlight spectrum (Figure 2). The ultimate achievable efficiency between a theoretical system…

next flagship mission we have is called Gigantas I. Gigantas is the word Enceladus in Greeks, which means a very bright satellite of Saturn. By sending a space orbiter and a lander to the sixth largest moon of Saturn and the brightest world in the solar system (NASA, 2015), We can easily accomplish this researching mission and bring lots of valuable data back to earth. Enceladus, with approximately 310 miles diameters, is one tenth of the Saturn’s largest moon. (NolaTRedd, 2016) It was first…

Harish Hande (a)Entrepreneur background: A social entrepreneur from India, who cofounded selco India in 1995. He was awarded with the Ramon Magsaysay award for 2011 for “his hardheaded efforts to put solar power technology in the hands of poor, through his social enterprise SELCO INDIA. He was born in UDIPI district, KARNATAKA and brought up in ROURKETA, ORISSA,INDIA. He studied his basic schooling in Orissa in ISPAT ENGLISH MEDIUM SCHOOL, he went to IIT KHARAGPUR for his…

When you hear the word "Tesla", what comes to mind? Let me guess,....cars, right? Well, that was the answer I was hoping you were thinking about and the direction I knew you were headed towards. This idea of Tesla being closing connected with cars has been an "ideal" concept that has been implanted in our minds from generations to generations. We have tagged these two together so that we are able to easily associate them with being involved in the automotive industry. It is a fact that Tesla,…

but for the worse of our environment. By being an engineer, you have the power to design, build, and maintain engines. Engineers also have a range of career opportunities. Carbon dioxide has increased the earth 's temperature by 0.5 celsius in the last one hundred years. Due to the increase use of oil, gas, and fossil fuels we are polluting our air and environment. I believe we must sustain our environment by using solar panels on our homes or energy that does not give off any bad chemicals into…
