To discuss how difficult would it be for Hong Kong to develop and promote biofuels to replace petroleum as car fuel‚ we should consider the matter from geographical ‚ economical and safety aspects. From geographical perspective‚ biodiesel feedstock available in Hong Kong is waste cooking oil and animal fats. Due to the limited space‚ it is not possible to build many biodiesel production plants in Hong Kong‚ as a result the supply of biofuel would not be enough. Moreover‚ Hong Kong has heavy use

Impact of Fuel Price Deregulation in India Introduction Empowered group of Ministers on Friday‚ 25th June 2010‚ took a decision to decontrol the petrol prices increasing it by 3.50 per litre & that of kerosene by Rs 3 a litre. While petrol is mainly used by the middle class for cars‚ kerosene is used by the poor for power. Diesel prices rose by Rs 2 per litre and might be freed up in the future. Cooking gas prices were raised by Rs 35 a cylinder. Govt. has indeed taken a bold step by deciding

Abstract: In Rockets and Missiles combustion gas of an integral burning of a propellant flows along the duct of the propellant. If the nozzles attached to a rocket motor are removed‚ the pressure on the duct becomes equal to atmospheric pressure and no sonic velocity is attained at the rear end of the duct. Then no thrust generated by the combustion of the propellant. In nozzleless propulsion the mass burning rate of the propellant in the duct is increased and the flow reaches sonic velocity

Southwest Airlines Fuel Hedging and Relations to Profitability Abstract In order to stay airborne‚ a passenger airline has to consistently generate profits. Profits come only from paying passengers‚ hence all stratagems must be customer oriented. In a scenario where there are many airlines competing with each other‚ one way of attracting passengers is to keep the cost of flying low‚ while providing value for money. On the other hand‚ expenses must tightly controlled to reach and stay at the

Fossil fuels comprise 80 percent of current global primary energy demand‚ and the energy system is the source of approximately two thirds of global carbon dioxide emissions as of 2015 (Foster and Elzinga). For decades‚ people have argued about whether fossil fuels are helpful to the planet and sustainability. Although‚ there is no right or wrong answer because renewable and non-renewable resources have disadvantages and advantages. There are very many different variables to be considered in this

INTRODUCTION According to Wikipedia‚ fuel is any material that stores energy that can later be extracted to perform mechanical work in a controlled manner. A fuel contains energy‚ mostly heat‚ which can be released and then manipulated. Most fuels used by humans undergo combustion‚ a redox reaction in which a combustible substance releases energy after it ignites and reacts with the oxygen in the air. Other processes used to convert fuel into energy include various other exothermic chemical

Using ethanol as an alternate fuel‚ or fuel extender includes a heterogenous agglomeration of advantages and disadvantages. On cars: ethanol is preferable to lead as an octane booster. A 10% addition of ethanol to petrol is more effective than lead at boosting octane rating (+2.5) and making car run smoother. It’s cheaper than lead‚ and ethanol-blended fuels leave no gummy deposits‚ thus keeps engine clean. Although a minimal 10% ethanol blend should be compatible with internal combustion engines
