Bockris, John O’M.Last Updated on 2013-10-31 01:06:04
John O’M. Bockris, an Australian electrochemist, coined the term “hydrogen economy” in the 1970s. Bockris’ hydrogen economy describes a system in which hydrogen would be used to transport energy from renewable sources over large distances and store it in large amounts. In 1962, Bockris first proposed a plan to supply US cities with solar-derived energy via hydrogen. In 1971, he published the first article on hydrogen in a referred journal. Bockris published Energy: The Solar-Hydrogen Alternative in 1975, one of the first detailed description of what a solar-hydrogen economy would look like.

The report presents a new economic index, which looks beyond the traditional short term economic and development yardsticks of gross domestic product (GDP) and the Human Development Index (HDI). The Inclusive Wealth Index (IWI) assesses changes in a country’s productive base, including produced, human, and natural capital over time. By taking a more holistic approach, the IWI shows governments the true state of their nation’s wealth and the sustainability of its growth.
Twenty countries were assessed in the IWR 2012 over a period of 19 years (1990-2008). Together they represent more than half of... More »

Carbon Offsets: Growing Pains
in a Growing Market
There’s a market growing in the United States, but unlike markets that trade in tangible commodities, this one trades in the absence of something no one wants: greenhouse gases in the atmosphere. Hundreds of companies make it possible for individuals, organizations, businesses, and even events such as rock music festivals to proclaim themselves carbon-neutral by paying someone else to reduce...

Industrial uses of leadLast Updated on 2013-09-17 22:29:34
The Toxics Use Reduction Institute is a Massachusetts government research entity that has used the unique usage data from the state pollution and prevention program to create selected chemical fact sheets. The following is from the Turi Lead Fact sheet.
In 2004, Massachusetts manufacturers used more than 3.5 million pounds of lead and lead compounds.
The total global industrial consumption of lead in 2003 was estimated to be 15.1 billion pounds, and the U.S. consumption of lead in 2003 was estimated to be 3.06 billion pounds. The greatest use of lead is in lead-acid batteries, however lead-acid batteries are not manufactured in Massachusetts.
Lead has a low melting temperature (327° C) for a metal and is extremely malleable, which enables easy casting, shaping, and joining of lead products. Lead can be recycled as a secondary raw material from lead-acid batteries and... More »
