Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity.

I wanted to do since early age‚ rather a path that piqued my interest during my years at university. I particularly enjoyed studying science however I became aware of the big current issues: health inequalities‚ ageing population‚ disease outbreaks; and decided I wanted a career that confronted these without leaving the field I enjoy most: science and healthcare. The doctor became an obvious choice; I was looking for a role that possesses political impact while remaining clinical scientist‚ Public

The "fuel cell cars" currently being advertised are being touted as "having no emissions except water." In a limited sense that is‚ in fact‚ true. However‚ if the entire fuel cycle for the car is considered it most certainly is not. The fuel used by the fuel cell is hydrogen‚ very pure hydrogen. Combined with oxygen from the ambient air‚ the fuel cell produces electricity that powers an electric motor and other devices in the vehicle--just like the battery-driven electric vehicles already on the

have even risked their lives in its cause. Space exploration holds a special place in science as it is something that we know a lot about‚ yet there is so much we need to learn about the cosmos. Space travel and space agencies all over the world are developing new theories‚ technologies‚ and plan to take space exploration to the next level; beyond the Moon. There are many things that need to be taken into consideration such as human risk and how space travel‚ which is such a new thing to humans

Space Exploration: A Waste of Resources? From the beginning of time‚ human life has been awestruck by the curiosity of space; this curiosity led to the formation of myths about space exploration which began a debate that is still to this day heavily debated. In today’s times‚ all are aware that the myths formed centuries ago were‚ indeed‚ incorrect‚ however‚ they were right in the sense of starting a debate that has yet to be settled (Space). Many years after the formation of the myths‚ President

The Indian Space Programme‚ from its very inception‚ has been geared towards national development. It has harnessed space technology for the benefit of our society right down to the grass roots level. Development of Thought: The remarkable development in space technology and its application during the last three decades have firmly established its immense potential for the development of the human society as a whole. Space platforms are now being extensively used for reaching global communication

Space exploration has been increasing greatly in the last 50 years. It has allowed us to understand the greatness of the universe and the endless possibilities it offers us. Our planet‚ Earth‚ is inhabited by approximately 6 billion humans. This is well over our natural carrying capacity (the amount of resources there are to sustain our population) but with techniques such as farming‚ we have manipulated our resources to provide us with enough food‚ but alternate solutions are needed.

Space is a beautiful‚ but dangerous place‚ and has wonderful resources. If we do not go to space people will never see‚ examine‚ or even bring back the amazing things they can find. In order to see these things‚ we need space exploration. John F. Kennedy’s speech at the Aerospace Medical Center and Joan Vernikos’ article “Is Space Exploration Worth the Cost” both state space exploration expands our knowledge and creates wealth. This knowledge is important for many reasons. Some materials in space
