The Great Transition: Shifting from Fossil Fuels to Solar and Nuclear Energy is a book that presents a definitively anti-fossil fuels stance on renewable energy written by Lester Brown, a lauded environmental scientist with more than 50 years of experience in the field of renewable energy who is certainly qualified to write about the topic. In the first half of the book, he discusses why society should phase out usage of fossil fuels, especially coal, as quickly as possible in order to prevent…

Is Global Climate Change a Hoax? Are humans to blame for the Ice capes melting and rapid changes in our weather patterns? What motivated President Elect Donald Trump to say that global climate change is a hoax. The present environmental warming trend is a huge topic today and an issue that raises great debate around the world. The earth is home to billions of humans, plants and animals, we all need the earth to sustain life. Therefore, the wellbeing of this planet is of major concern. This essay…

being converted to a usable source of electricity with the use of photovoltaic cells/modules, also called solar cells/modules. One spaceship, called the ISS, uses decades old solar cells which convert 14% of the sun’s energy into electricity which shows its (the Sun’s light) strength, but the main question spaceship builders want to know is “Where is the edge of sunlight?”, aka where does the solar energy fall off so much that it is no longer useful to harness. Another path of research that…

why renewable energy sources have become more important these days. Few other Reasons include advantages like abundant availability in nature, eco-friendly and recyclable. Many Renewable energy sources like solar, wind, hydel and tidal are there. Among these renewable sources solar and wind energy are the world’s fastest growing energy resources. With No emission of pollutants, energy conversion is done through wind and PV cells. Day by day, the demand for electricity is rapidly increasing.…

Modern spaceflight is something that is wondrous to many people. It is an important topic mainly because advancements made in this field could determine the future of the planet and the human race. The main question on this topic is who should be leading the effort to explore the cosmos, private persons and companies or governmental institutions? Although the modern day space initiative is being mostly spearheaded by private persons and industries, in my opinion, government funded space programs…

kilometres in altitude. The temperature rises rapidly in the thermosphere due to the high absorption of incoming ultra violet radiation through atomic oxygen, and reaches highs of up to 1500˚C. The thermosphere can also expand when there is high incoming solar radiation absorption. The air density and air pressure in the thermosphere is very low. In this layer of the atmosphere the main gases in the air is atomic oxygen, atomic nitrogen and helium. The reason why it is atomic oxygen and atomic…

The two main types of lights are the sun and the moon, respectively designated as a greater and a lesser light. One reason the moon may be lesser is because its surface reflects the light of the sun rather than creating light within itself, like the sun. The notion of a greater light and a lesser light is similarly expressed in John 1. Jesus, as the son of God, is the ‘true’ - in meaning perfect and ideal - light. John is a witness to the light, not the light itself, suggesting his figure as a…

mars. The two methods are the SEP-Chem and the Hybrid method. In the SEP-Chem architecture, the system destination and the propellant return or the stages are pre-deployed proceedings to the troop leaving by the spacecraft of the cargo and it is a solar electric. While in the Hybrid approach, the systems of the destinations are also installed before the troop leave via the SEP, but the spacecraft that is crewed syndicates the SEP relatively with the chemicals engines that are small. The…

Table 11: Solar energy collector type (Source: Kalogirou (2004)) In the textile industry, energy is mainly consumed for heating of liquid baths close to 100 oC for washing, bleaching and dyeing. Drying processes usually use hot air or gases from 100 to 130 oC as shown in Table 12. In a solar process heat system, interfacing of the collectors with conventional energy supplies must be done in a way compatible with the process. The easiest way to make this is by using heat storage, which can also…

The history of earth is hard to imagine without our moon. The moon has had an impact on the earth in many different ways. For as long as man walked this earth, the moon has affected the tides and even the metals of the earth. The phases of the moon are still used to help guide the harvest, and even help determine the time of the river floods. The moon is a place that we know little about and very few people are lucky enough to get to experience it in person. Some interesting facts that we know…
