These vehicles are referred to as Clean, Green and Keen: Clean is due to the no local emission and very minute global emissions, Green because they are in accordance with environment friendly principles, and Keen is attributed to it for the intelligence aspect (Chan and Chau, 2001), and according to research studies it was essentially declared that when compared with the traditional jets powered by conventional fuel, the aircrafts powered by hydrogen fuel are relatively better with regards to performance, cost, noise, pollution in the air, and they are efficient in energy usage (National Research Council, 2001, 32).
Despite the environmental benefits of these technologies, the dilemma pertains to the integration of the clean vehicles into the societies of contemporary times, since they are clutched in the vicious cycle: wherein the prices of the vehicles are high and thus the demand is low due to no mass production, which cannot be undertaken due to low market demand, hence unfortunately keeping the advanced technology out of the market, and deepening the carbon lock-in situation (Chan and Chau, 2001). The massive growth in suburbs has increased the home to work travel distance, hence the commuters began to rely on fuel powered cars, but ignored the drastic negative effect on the environment due to their personal advantage. With the advent into the era of increased freedom of press, and extensive development into the ‘green’ awareness campaign has resulted in the increase in demand for environment friendly technology, and thus gradually bringing the world out of the vicious cycle of technology lock-in. Hence as a result of this increased awareness the demand for electric cars and hydrogen powered jet planes has also hiked. Electric cars are the future choice vehicle for transportation, since they depict rapid advancement in technology and hence efficiently link computers, batteries and the electric motors into a complete system which is
