The Power of Water Essay

The Hydrogen Fuel Cell could revolutionize the world. This ingenious technology, which creates electricity from the chemical reactions of hydrogen and oxygen has, in its 150-year history, passed many of the critical tests along the path from invention to innovation. Recent developments in fuel cell technology and concurrent developments within the energy and automotive industries have brought the world to brink of the fuel cell age and the hydrogen economy.

Solar energy can be turned into electricity through solar cells 15%=cheap, 40% efficiency=expensive. Caloric theory of heat=caloric fluid flows from hot object to cold. Heat engine=

However, some pundits are concerned that adopting hydrogen energy as the sole strategy for the issues facing the automobile’s future is problematic because of the lengthy time frame in which they are projected to become ubiquitous. Furthermore, the present infrastructure for the distribution of hydrogen fuel sources or the production of hydrogen fuel cells is not only insufficient, but slow to develop. As such, fossil fuels are presently the main source for hydrogen production, which means that hydrogen vehicles do not successfully decouple the automobile from a fossil fuel economy. This is also widely inefficient because it will generate four times the carbon dioxide emissions generated by gasoline efficient automobiles. Furthermore, compressing hydrogen for the purposes of

Hydrogen fuel cell vehicles (fcvs) have not been around for long, but over the past decade that have developed into a new potential successor of the combustion engine. Fcvs function the same as an electric cars but the difference is the hydrogen fuel cell stack. Hydrogen fuel stacks are just multiple layers of fuel cells stacked up and when hydrogen is pumped in to mix with oxygen a reaction takes place. From this reaction electricity and water vapor is created. The electricity carries on and powers the electric motor(s) in the car. The vapor is released from the exhaust and since only water vapor is released, no harm is done to the environment.

This journal article emphasizes the importance of the environment and the potential for public health complications due to air pollution. The public health problems are most apparent in industrialized and developing countries where motor vehicle emissions is a significant contributor to poor air quality in urban areas. In this article, hydrogen is explored as a technological solution to this environmental problem. Hydrogen plays a significant role in the quest for a low-emission, environment-considerate, cleaner and more supportable vitality framework. Hydrogen has exceptionally unique properties as a transportation fuel, including a fast smoldering speed, a high successful octane number, and no poisonous quality or ozone-shaping potential. It has much more extensive points of confinement of combustibility in the air than methane and

The purpose of this experiment is to explore how temperature affects the expansion and contraction of gases using latex balloons. Therefore the research question is: what is the effect of temperature on the expansion and contraction of balloons? This would demonstrate how a balloon is able to expand and contract as the force and frequency of the

Federal Government and oil companies put forward hydrogen fuel cells as a better alternative to gas and battery electric cars. In contrast, interviews with two hydrogen experts gave details why fuel cell vehicles are not likely to be available for another 15-20 years if ever, whereas battery electric technology is available now, has been rapidly improving since the mid 1990s and is cost effective.

In these following paragraphs, the paragraphs will be about about balloons. There are three different types of balloons such as gas balloons, hot-air balloons, and sport balloons. According to Russell Lee, gas balloons can be filled with gases such as hydrogen, helium, natural gas, or any other gases that are lighter than air. Hydrogen is the

It derives energy from spinning water turbines. Hydroelectric power is a low-cost, renewable, air pollution-free energy source. Unfortunately there is not much room for this source left in the US and building large dams, flooding valuable river valleys, and eliminating free-flowing rivers are the negative externalities of this alternative. Electrolysis of water could be used to convert biomass (plants or plant-based materials) into methane or electricity to generate hydrogen gas. Current technology with little improvement could lead to these fuels being used more abundantly. Moreover, the storage, use, and transportation of these fuels would be

Honda has already produced a hydrogen fuel cell concept car they claim is “overall 64% energy efficient”. To put this into perspective in the average gasoline combustion engine “only about 20 percent of the thermal-energy content of the gasoline is converted into mechanical work”, making it 20% energy efficient [5]. This new line of cars could bring about jobs in the automotive industry and all industries that branch from it. As of right now the commercial market for hydrogen gas produced from the use of fossil fuels is at about $100 billion. A majority of this hydrogen goes into producing fertilizers and petrochemicals [1]. All it would take is an inexpensive source of green hydrogen, such as the one recently discovered, to completely change this industry.Overall hydrogen has the ability to bring about jobs and continued advancements in every market and industry touched by it. This could be just about every industry when considering how important transportation and shipping are to the economy; hydrogen would give them an inexpensive fuel for transport. Hydrogen fuel could do this all the while solving our most important problem of finding a renewable energy source.

When most people think of Hydrogen they think of the Hindenburg. The Hindenburg was initially supposed to be lifted by Helium. However, because Helium was so rare and expensive at the time, Hydrogen was used instead. Hydrogen was very cheap, it could be manufactured in industrious amounts and it is lighter than Helium; Hydrogen is also the most substance to date where Helium is not flammable at all. When the Hindenburg was launched it only took it about 32 seconds for the entire ship to fall and burn completely due to the 7,000,000 cubic feet of Hydrogen being used to get off the ground. Out of the 97 passengers only 62 survived this tragic event. Welcome to Hydrogen.

Scientists have also figured out how to harness solar energy, using electricity from photovoltaic cells to yield hydrogen that can be later used in fuel cells. But hydrogen has failed to catch on as a practical fuel for cars or for power generation in a world designed around liquid fuels.

Recent years have shown an increasingly large need for a practical renewable energy source for such reasons as diminishing fossil fuels and increases in greenhouse gasses. Hydrogen appears to be a way out of this gasoline-dug hole, or at least, a way out in the future. Hydrogen fuel cell cars are being engineered as we speak as the technologies to refuel them cleanly are being proposed. Unfortunately, most of the technologies associated with hydrogen are still in the prototype/pre-production stages and require better enhancements before becoming mainstream. This paper assesses the practicality of hydrogen power in cars both now and in the future while explicating the actual process of how a

Hydrogen powered vehicles initially became a reality with the invention of the first internal combustion engine in 1806. The engine was powered by a mixture of oxygen and hydrogen gases. This led to the first hydrogen powered car in 1908. Hydrogen powered vehicles were further advanced in 1935 with Henry Garrett’s electrolytic carburetor which allowed the cars to run on tap water. In the 1970’s, Archie Blue created and patented a new carburetor that produced enough H2 (hydrogen) gas to power a car motor (History of Hydrogen, n.d.). Today, most commercial hydrogen vehicles use fuel cells to power their engines.

Another possible source of energy, though not proven, is hydrogen power. Hydrogen can produce a great amount of energy with almost no pollution. Fuel cells are able to combine hydrogen with oxygen, producing energy which possibly could be used to power cars, buildings, and other devices. Hydrogen fuel cells are a promising technology for the years to come.
