When you burn a gallon of gas in an internal combustion engine ....

“When you burn a gallon of gas in an internal combustion engine, about two-thirds of the energy produced in that process is lost as heat either through the exhaust system or through the radiator,”

- Donald Morelli, professor of chemical engineering and materials science and head of the center - Michigan State University’s College of Engineering

Michigan State University’s College of Engineering recently received three grants totalling $141.5 million for various alternative energy projects.

Become a Presenter at the All Renewable Energy Event

RETECH 2010 will offer an exciting, high-level, comprehensive Conference Program of speakers from every aspect of renewable energy technology, industry, market, finance, and policy. RETECH 2010, the first all-renewables event in 2010, will feature key leaders who will be addressing global issues and perspectives that impact our industry. We welcome industry leaders, ACORE Members, current exhibitors and sponsors, as well as delegates from all around the world, to nominate interested speakers.

The conference program will address several timely questions:

* What does it take to secure government and private capital financing for my renewable energy projects in 2010?
* What is the state and direction of renewable energy technologies, companies, and buyers?
* What is the outlook on public policy around the world, and here in the U.S. at federal and state levels?
* What are the key issues in the market today? How can they be resolved? What is your role in that process? Plus much more.

We welcome your participation at the Global Business Conference at RETECH 2010. Speakers for the RETECH 2010 Program will be selected by a program committee composed of approximately 25 renewable energy leaders from the technology, research, manufacturing, systems, and services sectors plus non-profit and government. This committee will develop the thematic areas of the program, and review all speaker submissions received by Wednesday, October 21, 2009.

AquaSim software and tutorials

I downloaded AquaSim demo version and some of tutorials as it is a recommended and used modeling package for our M. Sc course. The

AQUASIM has been designed to provide a more universal identification and simulation tool for a class of aquatic systems important in the

environmental sciences. An additional important program design criterion was user-friendliness, which was achieved not only by providing a graphical

user interface, but also by utilizing a communication "language" familiar to environmental scientists. AQUASIM is extremely exible in allowing the user

to specify transformation processes, and, in addition to perform simulations for the user-specied model, it provides elementary methods for parameter

identiability analysis, for parameter estimation and for uncertainty analysis.


AQUASIM was developed in the years 1991-1994 in the Computer and Systems Sciences department of the Swiss Federal Institute for Environmental Science

and Technology (EAWAG), CH-8600 Dubendorf, Switzerland, and it is maintained and extended since then. The program was designed mainly for internal use in research and

teaching, but is also available to the public.

My Carbon Foot Print

What is Carbon Foot Print?

The definition of the Carbon Foot Print can be as follows.

‘‘The total set of greenhouse gas emissions caused directly and indirectly by an [individual, event, organisation, product] expressed as CO2e.’’ 1

The carbon foot print of above parties encompasses three ways of carbon emissions.

1. Direct emissions that result from activities such as combustion of fuels, emission of gases during operation, production and manufacture, and running of a vehicle fleet

2. Emissions from electricity usage

3. Indirect emissions from products and services that the organization does not directly control (Emmision from indirect activities of the main process such as preparation and transport of the raw materials)

Carbon Foot Print Calculators

There are many online and offline carbon foot print calculators available. I choose which is an online calculator which encompasses two solutions for business and individual calculations.

This calculator provides calculations on following major areas.

1. Home

2. Flights

3. Car

4. Motorbike

5. Bus and train

6. Secondary

Transport Phenomena, 2nd Edition by by R. Byron Bird (Author), Warren E. Stewart (Author), Edwin N. Lightfoot (Author)

This is the recommended text for Transport phenomena subject on my Sustainable Process Development Master of Science degree programme. Today I started to study this book as our lecture Dr. Shantha Amarasinghe is taking this book as a model. Because of R. Byron Bird's (Author), Warren E. Stewart's (Author) and Edwin N. Lightfoot's (Author) deep analysing and great approch this book has become a standard book in trasport phenomena and there way of looking into transport phenomena is called a "BSL" method.

ExSact by Exelus Inc. - an alternative catalyst for alkylation process in oil refinery

In ordinary petroleum refining process Hydrogen Fluoride or Sulfuric Acid is being used as the catalyst for alkylation process. It is the unit operation which ensure a high-octane component for gasoline. But Hydrogen Fluoride or Sulfuric Acid are toxic and dangerous specially when an accident occurred. Environmentalist and unions of refineries make voice against use of Hydrogen Fluoride or Sulfuric Acid which can be harmful for employees and neighbours. So industrialist try to find an alternative.

Exsact is a solid-acid catalyst which essentially are rocks that act chemically as acids. Exsact is made of the mineral zeolite and other metals.
