Introducing Snap Shots from Snap.com

Introducing Snap Shots from Snap.com

I just installed a nice little tool on this site called Snap Shots that enhances links with visual previews of the destination site, interactive excerpts of Wikipedia articles, MySpace profiles, IMDb profiles and Amazon products, display inline videos, RSS, MP3s, photos, stock charts and more.

Sometimes Snap Shots bring you the information you need, without your having to leave the site, while other times it lets you "look ahead," before deciding if you want to follow a link or not.

Please feel free to comment upon this widget or my widget approach in general.

Should you decide this is not for you, just click the Options icon in the upper right corner of the Snap Shot and opt-out.

Thinking Outside The Box - Fuel from Coal-Eating Microbes - System 4_Bis

THE BOX -VENN DIAGRAMME opposite.

Burning coal for heat and energy is too old to dwell on. It was the logical step during much of the last century to carry this to today's high temperature materials assisted power generation. To continue pollution represented by the most abundant green house gas -CO2 must be mastered hence the necessary additional steps of CO2 capture and sequestration. Various processes exist, unfortunately only at fairly large pilot size but well under predicted sustainable climate predictions-requirements.

OUTSIDE THE BOX- System 4 Bis:
Relatively new biochemical process results suggest a new low-temperature_lower energy loss process route whereby methane gas fuel is generated from coal by coal eating microbes.

The incentives to develop this new route are:

- Low Temperatures, less energy intensive.
- Half as much carbon dioxide is emitted as does burning coal.
- reduce or help eliminate the anticipated need to import natural gas in the future. (Russia - Ukraine etc)
- Substantial interest and historical evidence for in coal bed methanisation:
1. Luca Technologies, a start-up based in Golden, CO, has raised $76 million to scale up a process that uses coal-digesting microorganisms to convert coal into methane.
2. Andrew Scott, former professor of economic geology, Univ of Texas,Austin is the founder Altuda Energy Corporation, based in San Antonio, TX A. Scott


Having said this, the framework may still be argued to hold if accent is given to Power Industry rather than Coal Fired Power. Clearly, however these concepts are radially different. The microbiological route appears to hold much promises and at the very least hopefully will stimulate the over mature Coal Fired Power players to accelerated their work to achieve all the objective the silent majority aspires to - much cleaner energy and eventually renewable energy. In the meantime the cross disciplinary- Metallurgical and Materials Industries will evidently still play an important role in anticipating evolving requirements.

Rust cleans up pollution_From the previous post of Top 100 Materials Science Stories - My biased choice - "Got Pollution? Get Rust from 2003"

1,000-square-foot plot at a pharmaceutical plant in North Carolina using just $1,000 in raw materials has been decontaminated by Wei-Xian Zhang, an environmental engineer at Lehigh University in Pennsylvania.

The scientific methode : 20 pounds of iron nanoparticles—superfine iron dust.

As iron rusts, it unleashes electrons that can break down organic pollutants such as dioxins, PCBs, and many pesticides. By growing iron atoms into incredibly small particles, Zhang increases the number of electrons they release as much as 1,000-fold. He then mixes the ultrafine powder with water so it can be pumped into the ground. A few days after injecting the iron powder into contaminated land, all that is left behind are simple, nontoxic hydrocarbons. The iron dust eventually dissolves harmlessly into the groundwater. Early next year, Zhang plans a larger test, treating a 100-acre site in North Carolina. He is also developing a commercial version of the process.

Since this work was reported in 2003, more results and the success or failure to reach the original expectations must be known. Looking forward to up-dating this advanced metallurgical chemical and biochemical engineering interdisciplinary work.

It goes without saying that both I and Discover Magazine would be pleased to learn of readers top pick, cf Full List Link below.
