ABSTRACT Care for the environment is often portrayed as detrimental to economic growth. For too long economics and environment have seemed like players on rival teams. There is a long-standing debate on the relationship between economic development and environmental quality. Sustainable development emphasizes the need for integration of economics and environment‚ as well as promoting intra and intergenerational equity. From a sustainable development viewpoint there has been a growing concern that

Potatoes May Power The Batteries Of The Future Friday‚ June 18‚ 2010 - by Ray Willington Oh‚ batteries. Can’t live with ’em‚ can’t live without ’em. It sounds like a power ballad‚ but it’s the story of our lives around here. We’ve been dealing with lofty promises and batteries that kick the bucket far too early‚ for years now. And the fact that we’re still dealing with lead-acid batteries is sort of a baffling thing to wrap one’s mind around. But all of that just might be changing. We won’t get

If there are more coins in the pile‚ then the more electricity it can produce‚ because the more electrons you have‚ the more electricity you will get. Batteries are expensive‚ but you can make one for exactly 24 cents! In this experiment‚ you will make your own voltaic pile using

Biodiesel Fuel The biggest problem the United States faces today when we talk about becoming energy independent is replacing the gas we use to power our vehicles. When we talk about replacing gasoline as the fuel we use to power our vehicles‚ biomass‚ hydrogen‚ and fuel cells are the three most talked about alternatives. Biomass‚ which is organic material made from plants and animals‚ contains stored energy from the sun. Biomass in the form of bio fuels can be used to make the same products

because it allows them to know how fireflies and other species produce a glowing light naturally. Also one could identify blood at a crime scene with chemiluminescence. It is observed in spontaneous reactions like during an electric discharge‚ electrolysis‚ or upon exposure to light or ionizing radiation. My group mixed a variety of chemicals with luminol to produce light. The controlled variable was the luminol. My group used the same amount throughout all of the experiment. The chemicals that were

Galvanic Corrosion: Galvanic corrosion (also called ’ dissimilar metal corrosion ’ or wrongly ’electrolysis ’) refers to corrosion damage induced when two dissimilar materials are coupled in a corrosive electrolyte.
