Davy Powergas proposes floating chemical plants Davy Powergas has unveiled an unprecedented scheme to build chemical plants at one point and then ship them to a final destination for installation. At a press conference in New York City last week, the British engineering firm discussed its concept. In this case the company was talking about a floating methanol plant, but the firm says the concept can work with a number of different types of chemical plants. The idea behind this concept is that it may be cheaper to build a methanol plant in a developed country and ship it on a barge—which later becomes the base of the plant—to a less-developed country where, presumably, labor is not sufficiently skilled to build the plant Gulf Canada engineer checks test strip economically. during paving in Michigan Although no methanol plants have been built on barges and no contracts which up to 50% of the asphalt is re- have yet been signed to build one, placed by molten sulfur.

The company points specially designed blending unit that to examples of shipboard plants that Gulf calls a sulfur-asphalt module or already have been built, including SAM.

Government to review industrial innovation The White House has established an interagency committee to conduct a comprehensive review of issues and problems related to industrial innovation. The 14-month study will be under the direction of the Secretary of Commerce and is expected to develop a number of Presidential-level options that address ways the government can assist industry in strengthening its research efforts. In announcing the new study, the White House noted that "in recent years private sector R&D has concentrated on low-risk, short-term projects directed at improving existing products. Emphasis on the longer-term research that could lead to new products and processes has decreased." As a result of these trends, White House science adviser Frank Press, who helped formulate the study, has said, "The health of our economy is being adversely affected by a lag in our productivity and decline in our industrial innovation. ,, When the White House innovation study was first proposed earlier this year, Dr. Jordan J. Baruch, assistant secretary of Commerce for science and technology, noted that "the federal government is clearly a critical actor in the innovation process." Questions about its role that need to be answered, according to Baruch, include: How do we strengthen the patent system and minimize the risk of strengthening monopolies? And how do we subsidize industrial research and not simply displace corporate funds into profits? Other members of the interagency committee besides Press and the Secretary of Commerce are the Secretaries of Energy; Defense; Health, Education & Welfare; and Treasury; the Attorney General; the administrators of the Environmental Protection Agency and the National Aeronautics & Space Administration; the directors of the National Science Foundation and the Office of Management & Budget; the chairman of the Council of Economic Advisers; the assistant to the President for national security affairs; and the special trade negotiations representative.
