Fracking is Slowly killing Our Planet and the Solution is Not Out of Reach Sure, fracking can provide a quick and easy process of obtaining fuel, but it is also an quick and easy way of killing our environment. Fracking is a popular practice done around the world; if at high pressure, highly toxic chemicals mixed with water can extract gas from shale. This toxic mixture, at high pressure, is put into a pipe that extends far underground; gas pockets are released and then rise to the top of the…

Alternative fuels are perceived as being less likely to evaporate or otherwise find their way into the air before combustion and are less ozone-forming and less toxic if they do (Gushee, 1995). Another benefit that may be reaped from the use of alternative fuels is that gases burn cleaner than gasoline (see Table 6). As a result, less harmful emissions are created as a result of burning alternative fuels. There are of course disadvantages to the use of alternative fuel driven cars. Vehicles…

Health Care systems is based on Stem cells & Autophagy As shown in (Figure1), stem cells and Autophagy are a revolution in the medical field. Fig 1.The potential uses of stem cells The city is mainly depends on Genetic Engineering and urban agriculture Micro farming community gardening and institutional gardens ,In addition to farming some delta lands to…

Hydrogen vehicles are similar to electric fuels as they both run on a motor powered by electricity. However, what makes it different is where the electricity comes from. The hydrogen vehicle is powered by hydrogen fuel and batteries power the electric vehicle. Hydrogen vehicles do however come with disadvantages, as it is highly flammable because it is a very powerful source of fuel. It is also very hard to store as gas is easily transported through pipes but hydrogen…

A catalyst layer is usually the slimmest layer in a PEM fuel cell; however this is an extremely complex component because of its porosity, several phases, and reactions (Spiegel 2008). An efficient catalyst layer should provide several functions at the same time; transporting the electron and the proton, supplying oxygen and hydrogen and water management. The structure and composition of the catalyst layer affects all these roles. Optimization of the catalyst layer can provide for all these…

Quality Tools Case Study: Old Sarge Autobus II Fuel Cell Project Question 1: What Quality tools and concepts would your team use to find the root causes for the frequent maintenance? The Old Sarge Strategy Council program was launched to study and reduce, or eliminate the problems faced by customers and bus operators due to frequent maintenance to the fire/explosion suppression system that prevents fuel cells from exploding if struck from the rear by another vehicle. Consequently, the…

Hydrogen fuel cell cars 1. What is hydrogen fuel ? 2. The advantage and disadvantage of hydrogen fuel cell. 3. How economical is hydrogen fuel ? 4. What health factor does hydrogen fuel on the population. 5. Does hydrogen fuel adverse effect on the environment.? What is hydrogen fuel ? Hydrogen fuel is very common and abundant element in our universe , hydrogen is also a promising source of "clean" fuel on earth. It is very…

fossil fuels such as coal. This is an issue because natural fuels such as coal are nonrenewable and harmful to the earth we live on. Since fossil fuels are nonrenewable, that means they will run out eventually because it takes tens of thousands of years for them to form. Other sources of energy include, but are not limited to, nuclear energy, solar energy, wind energy, and hydroelectric energy. Nuclear energy is very efficient but there are major liabilities…

Since the creation of electricity, people have searched for the most efficient source of energy. There are many common sources of energy, and they all have their own flaws. Many of the common energy sources are nonrenewable resources; therefore, they are not a logical source of energy for the future. Some of the energy creating processes can be very dangerous to humans and the environment. Many of these sources are not economical either. To be considered efficient, an energy source must be…

which the planet becomes increasing hotter due to the release of large amounts of greenhouse gases. These greenhouse gases that are affecting the environment to such an extreme extent are from human generated sources mostly by the burning of fossil fuels. This warming up of the planet poses a huge threat to all life on Earth. The other term “Flat” refers to the current state of the planet’s economy and how fast technology and services spread in the modern age. In recent years the Earth has…
