Sec. 1455. In order to provide for agricultural research, development, and demonstration projects having a national or regional application, the Secretary shall establish in existing Federal facilities or in cooperation with State and local government agencies, including State departments of agriculture, colleges and universities, or other qualified persons and organizations, including local nonprofit research groups, not less than three nor more than five regional solar energy research, development, and demonstration centers in the United States for the performance of agricultural research, extension work, and demonstration projects relating to use of solar energy with respect to farm buildings, farm homes, and farm machinery (including equipment used to dry and cure crops and provide irrigation), to be variously located so as to reflect the unique solar characteristics of different latitudes and climatic regions within the United States. Funds used in the operation of such regional centers may be used for the rehabilitation of existing buildings or facilities to house such centers, but may not be used for the construction or acquisition of new buildings.
