TIDAL ENERGY [pic] *75% of the planet’s surface consits of water. Our water supply transformed a barren planet into a lush green garden of life with a multitude of biodiversity. Water has easily fufilled our every need in many ways. As we near the twentyfirst century‚ a time when public attention is focused on the environment and society is increasing at an ever accelerating rate‚ the energy crisis continues to burden us. Questions of what to do about increasing energy demands and future requirements

Geothermal energy What is geothermal energy‚ and how can we use it in society? Geothermal energy is the use of the Earths very own energy. It’s renewable‚ clean and can range to easily acquirable hot springs on the surface or hot rock found a few miles below the surface. Or you can go a bit deeper and hit the extremities of the molten rock (magma). In the US around 80% of all geothermal hotspots are found on the western states i.e. Alaska and Hawaii. Wells are drilled deep into the underground

Nuclear Energy Should Be Continued The use of nuclear energy should be allowed to continue for many reasons such as nuclear energy is cleaner and safe when handled properly. An example of where nuclear energy is cleaner than other forms of energy such as coal-burning is in how the energy or heat is produced in the plants. In nuclear power plant the energy or heat it produced by the fission of Uranium; in a coal-burning plant the burning of coal produces the energy or heat. The Uranium power plant

Direct energy conversion system Direct energy conversion systems that could operate in the 100-700°C temperature range with high efficiencies (>30%) provide an attractive compact alternative to internal combustion engines for many military applications. They will also expand the possibilities for waste heat recovery applications. The core of the solution we are proposing is a metal/semiconductor nanocomposite that will allow us to modify four intrinsic material properties in order to fabricate

renewable energy? Well‚ because its renewable. Renewable energy will last forever and it cost close to nothing to get it. But it will always be their‚ unlike coal that once its gone‚ its gone. I think that the best process to get renewable energy is through geothermal plants. Some scientists think that the amount of geothermal energy stored in the earth will outlast our energy consumption and it may even outlast the sun. (Energy Informative) Geothermal is the most cost effective way to get energy‚ with

WHAT IS TORQUE? Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis‚ which we will call the pivot point‚ and will label ’O ’. We will call the force ’F ’. The distance from the pivot point to the point where the force acts is called the moment arm‚ and is denoted by ’r ’. Note that this distance‚ ’r ’‚ is also a vector‚ and points from the axis of rotation to the point where the force acts. (Refer to Figure 1 for a pictoral

Questions: 1. When we say that something gives us “energy‚” what does that mean? What is a biological definition of energy? When we say that something gives us “energy” it means that‚ that drink gave us power to get up and do things. It energizes us so we can accomplish something. The biological definition of energy is the strength and vitality required for sustained physical or mental activity. 2. What is the physiological role of each of the molecules in your table?
