FUEL CELL CARS Fuel Cell cars are a major part of the fleet of Zero-Emission Vehicles. The fuel cells are fueled with pure hydrogen and hence they are considered to be zero emission vehicles. Fuel cells have been used on spacecraft for many years to power electric equipment. These are fueled with liquid hydrogen from the spacecraft ’s rocket fuel tanks. Basic Mechanics Fuel cell vehicles turn hydrogen fuel and oxygen into electricity. The electricity then powers an electric motor‚ just like

SPACE EXPLORATION & TECHNOLOGY Traveling through space and exploring the unknown has been an unquenched curiosity of mankind’s since the beginning of time. Students of all ages‚ in schools throughout the world‚ are becoming more involved in researching space. They are following the current progress of space exploration‚ and discovering the learning possibilities that come from traveling through the last frontier. "Space Exploration" is an interdisciplinary unit combining multiple disciplines

PROPOSAL APPLICATION OF NANOTECHNOLOGY IN DIAGNOSIS AND TREATMENT OF DISEASES – CANCER. BY OLOWOKERE JOHN 1.0 Introduction Nanotechnology is the study‚ design‚ creation‚ synthesis‚ manipulation‚ and application of materials‚ devices‚ and systems at the nanometer scale (One meter consists of 1 billion nanometers). It is becoming increasingly important in fields like engineering‚ agriculture‚ construction‚ microelectronics and health care to mention a few. The application of nanotechnology

Introduction The world’s current way to produce‚ convert and consume energy comes with a price. Development of sustainable energy technologies which can continue providing the society with energy-derived benefits without further environmental destructions is highly desired. A series of green energy solutions‚ such as solar‚ wind and biomass energy‚ are employed in the hope of preventing the impending global energy crisis (Wang‚ Chem and Huang 2010). Microbial Fuel Cells (MFCs) which capable of harvesting

Engineering is a rapidly developing career field. There are many reasons why I would like to become an engineer. I am interested in SIUE’s Mechanical Engineering program. Mechanical Engineering is an exciting career field. In my youth‚ I was constantly designing and building an assortment of contraptions out of LEGO’s and K’NEX pieces. These objects included rollercoasters‚ cars‚ buildings‚ tractors‚ and many other machines. Growing up on a farm‚ I have always been interested in agriculture

Ethics and Space Exploration Christen Boyd PHI107: Philosophy of Human Conduct Prof. Carol Parker October 14‚ 2010 Ethics and Space Exploration In recent years‚ there has been a rise in debate over government spending on space exploration. It is hard to say that the deck is stacked in either way. There is much validity in the arguments from both sides of the gun. In this debate‚ I believe‚ the sides are both coming from the perspective of utilitarian ethics. Basically‚ it is a disagreement

Future large scale commercial activities in space will require raw materials obtained from in-space sources rather than from Earth‚ to overcome the high cost of Earth launch. This paper reviews the prospectiveness of non-terrestrial resources and notes the competitiveness of Near-Earth-Asteroids c.f. the Moon and Phobos or Deimos in terms of accessibility and likely resources. Astronomical work over the last fifteen years has increased the number of known Near Earth Asteroids (NEAs) from about 30
