Bio Fuels are clearly the most suitable alternative energy of the future as oil and coal are both rapidly vanishing and increasingly out of interest for nations wishing to avoid terrorist nations. Recently, algae has been discovered as an extremely suitable bio fuel because of its surprisingly high ratio of yield to area required for growth.
In 1960 Oswald and Golweke proposed the use of large‐scale ponds for cultivating algae on wastewater nutrients and anaerobically fermenting the biomass into methane fuel. Algae, like all bio fuels, harvests the energy from water and sunlight to produce oil which can be converted into biodiesel as well as the carbohydrate content to be fermented into ethanol (Benemann, Olst, et al. 1). The concept of using vegetal oil as an engine fuel likely dates back to when Rudolf Diesel (1858‐1913) developed the first engine to run on peanut oil, as he demonstrated at the World Exhibition in Paris in 1900 (Biodiesel 1). Using algae, however, is only a very recent concept as the first algae biodiesel plant only opened this year on April 1, 2008. The company, PetroSun, is expected to produce ≈4.4 million gallons of algal oil and 110 million lbs of biomass per year in their 1,000 acres. Fuel will not be produced immediately, but they will be building or acquiring ethanol and biodiesel production plants in the near future (Cornell 1).
With the ever‐rising prices of fossil fuels and the realization that our supply is severely limited, the need for an alternative energy source is rising steadily. Clearly the most efficient of the alternative options lies in bio fuels because they are naturally grown and thus have an unlimited supply, have virtually zero emissions, and can be us...

- Imagine a future in which you can fill your car with a liquid that has more mileage than gasoline and is just as biodegradable as sugar. This is the future of bio-diesel, and is well on its way to becoming the future we will live in. Bio-diesel has always been an area of study for researchers looking for renewable fuels, usually biodiesel is produced from plant waste, like corn husks, but recently it was discovered that bio-diesel could be produced with oils found in algae, which many people are considering to be our best option when it comes to alternative fuels....

- One of the most significant current discussions in sustainable aviation is alternative fuel for airplane, which is a serious argument; however, big question is that efforts to produce a more sustainable fuel to power aircraft are technically and ethically feasible. This paper going to investigate and show there is no alternative fuel to power aircraft in this time. The fuel using by airplane is fossil fuel, which is Jet A1 by burning this fuel there are impact on the global warming the researcher investigate what is the problem with fossil fuel (Jet A1)....

- 3. Alternative fuel Technology 3.1 Introduction: It has been proven consistently that acquiring more efficient technologies and progressing to increase in usage of AFVs will slow the increasing demand for gasoline in comparison to past years. A recent study has also suggested that AFV 's will decrease energy consumption from 26.7 quadrillions Btu in 2012 to 25.5 quadrillion Btu by 2040.This gives positive attitude when another research suggests that the no of vehicle usage on roads is going to double by 2040.Since not all alternative fuels are well suited for all modes of transport, and not for all sectors within a specific mode of transport i.e....

- Should Australia convert from fossil fuel to bio-fuel. Intro- fossil fuels are fuels that formed from the organic matter over millions of years. It is an energy source that is categorised as a non-renewable source of energy because it takes a large amount of time and pressure to produce fossil fuels. Therefore, fossil fuels are limited, and as time goes by, we are going to run out of fossil fuels. Background- There are many types of fossil fuels, and the most common examples of fossil fuels are the coal, natural gas and petroleum.... [tags: Carbon dioxide, Fossil fuel, Natural gas]

- I can recall countless afternoon strolls with my mother alongside the pond outside her office. The pond glistened in the sunlight with a slight green hue. Vividly colored fish dashed back and forth in the still water. A trail of ducklings followed their mother calmly atop the pond. I strained my eyes and caught a glimpse of a dark green turtle, camouflaged by the algae-laden water. It is truly awing that something as seemingly trivial as algae are being ardently pursued by research scientists across the globe today.... [tags: biodiesel, gasoline, renewable]

- Algae: Plant to Bio-fuel Introduction There is a lot of talk about the world’s source of energy going on these days and people are starting to ask questions about our sources of energy. Is it environmentally friendly. Does it make sense economically. For years the world has been highly dependent on fossil fuels that are extracted from the ground. These fuels power things from power plants, cars, plains, and many of the other modern conveniences that we enjoy. There is a lot of energy expended in the extraction and transport of these fuels as well as many negative environmental impacts.... [tags: clean fuel sources]

- Bio-Fuels By: Cody Gregory Many have said that bio-fuels are the fuel of the future, and others say it is just going to harm the atmosphere even more than are normal fuels. Well today we will be looking at some positives and negatives about bio-fuels. Biofuels have been around as long as cars have. At the start of the 20th century, Henry Ford planned to fuel his Model T’s with ethanol, and early diesel engines were shown to run on peanut oil....

- Oil palm is a multipurpose plantation yet it is also productive producer of biomass. Palm oil industry’s waste may provide an alternative sources of bio-fuel energy like bio-ethanol, bio-methanol, bio-hydrogen and bio-diesel. The oil palm is a well-known plants for its other substances of renewable energy with enormous quantity of biomass by-products that are developed to produce value added bio-plastic, methane gas, bio-compost, organic acids, plywood, animal feedstock and activated carbon. Commonly, palm oil forms around 10% of the whole palm tree, whereas the other 90% remains as biomass which is full of cellulose and fibre that generally used to generate steam for power generation in pal...

- What is Bio-fuel. Bio-fuels are fuels derived from sustainable and renewable biological sources (ABC’s). These sources, commonly referred to as Biomass, usually consists of either food crops (corn, sugar cane, wheat, and potato’s), various biological oils (peanut, sunflower, algae, and soy oil), or biological waste (waste vegetable oil, wood-chips, corn leaves and stalks, and yard waste) (Biofuels)(Biomass). Bio-fuels are often touted as a viable carbon-neutral replacement for carbon based fossil fuels.... [tags: Energy ]
