The USA Science & Engineering Festival to be held in Washington D.C. in the fall of 2010 aims to be "the largest celebration of science and engineering in the United States," according to members of ScienceDebate.org. It is being organized by Larry Bock, who created the San Diego Science Festival last year which drew more than 200,000 people.

Organizers said the national event aims to be a multi-cultural, multi-generational and multi-disciplinary celebration of science and engineering in the United States. They hope to draw more than a million people to an expo on the Washington Mall that could include presentations from more than 500 science organizations.

The group is modeling the U.S. event on existing international science festivals in the United Kingdom, Germany, Italy, India, Japan and Australia that typically last one to two weeks and draw between 100,000-1,000,000 people. The US event will include special programs in areas such as clean technology, alternative energy, sustainability and conservation.

There is no cost to participate. Organizers ask anyone interested to contact them before October 30th, 2009.
