Energy development

Solar Updraft Towers Solar updraft towers were designed as an alternative to other current energy sources that are nonrenewable by using kinetic energy to transfer heat. The technology in a solar updraft tower is that it incorporates a large greenhouse-type structure, referred to as a collector, which generates heat from the sun and transfers the heat by convection out of a tall chimney tower that is at the center of the structure. As hot air rises and evacuates from the top of the tower, a…

many different energy sources. There are two main types: renewable and nonrenewable. Renewable sources are sources we can use repeatedly without fear of running out. Some examples are water, solar, and wind. Nonrenewable have a short shelf life. They are slowly running out. Examples of these are coal, natural gas, and petroleum. The two I will be comparing are ethanol from corn and solar energy from the sun. Solar energy is self-explanatory. We harness the power of the sun for energy. Solar…

the State of Alaska creating problems especially within the rural villages, the city of Anchorage is in the heart of most of the energy production, as well as the North Slope Region. From manufacturing, natural resources in oil to creating energy from all forms (hydro, solar, wind, etc.), a solution to produce more energy for the city of Anchorage is essential. Energy production is the most crucial element when it comes to creating power and resources for any city, especially in Anchorage.…

Nuclear energy should not be a resource after what happened in Japan on 11 march 2011. That day a Nuclear power plantation has been destroyed by an earthquake in Japan. It causes radiation all around Japan and many people died. It doesn't matter if the disaster happened on Japan just because Japan is known for tsunami, earthquake, storm surge, and floods.This global warming situation is out of control for everybody so this can happen anywhere and if any natural causes hit any nuclear power plant…

Both the reading and the lecture attempt to discuss what the story of the weapon called "burning mirror" was in the Greeks navy who defended themselves with the Roman navy. While the lecture states three reasons for taking advantages of this weapon, not only does the lecturer disagrees with them, but she also presents some evidence to refute them all. First, the author maintains that the technology for manufacturing a class of large copper sheet for burning mirror could not exist in that time.…

Nuclear power. Worth is or not? Energy is what makes the human life function. Humanity has depended on electricity ever since “Thomas Edison invented the light bulb in 1880”. Ever since then humans have been inventing and finding new ways to make life easier for themselves. The one thing that all these ideas have in common is the use of electricity. The main sores of electricity are coal and oil. Coal and oil is an ideal power sores, but the only problem is it is not renewable and one day will…

Thorium has long been the subject of scientific research ever since its discovery, and now it appears that this obscure element may now be the energy source which could fuel humanity for generations to come. While thorium has a complicated history, the element remains very important to humanity for many reasons. Discovered about the same time as uranium in the 19th century, thorium has been well known to the scientific community for many years (World Nuclear Association). In fact, famous…

believe that we must not use uranium as an energy source. Many people believe that uranium is a clean and a good source of energy. It is most certainly not. It is dangerous and if there is a radioactive spill, many people can be fatally injured or even killed. Uranium is not an easy source to mine and it is extremely harmful to the air while transporting it to and from. Radioactive waste disposal is an undoubtedly big issue with having uranium as an energy source. A nuclear power plant creates…

Both the progress and energy independence frame promote nuclear power with the former presenting it as essential and beneficial, particularly in terms of technological and economic advancement, and the latter promoting it as a solution to dependence on foreign sources of energy. Counter to these are another five frames that criticise the use of nuclear power. Soft paths view it as environmentally hazardous, promoting greener energy, lifestyle changes and conservation as solutions…
