SCIENTISTS URGE THIRD WORLD TO FOLLOW THE SUN IN DEVELOPMENT

Solar scientists from around the world began a five-day congress in Zimbabwe, with key speakers calling for new technology to exploit fully the sun's energy to help develop the Third World.

''The new solar technologies, renewable sources of energy and their utilization will certainly alleviate some of the problems in the developing countries," Adnan Bradran, a deputy director with the United Nations Education, Scientific and Cultural Organization (Unesco), said at the opening of the conference Monday.In a keynote address at the meeting, William Charters, dean of engineering at Australia's University of Melbourne, urged the 500 participants to promote the use of solar power as an alternative to fossil fuel.

At least 75 percent of the world's energy comes from fossil fuel and demand is increasing despite dwindling resources, he said.

The congress, convened every two years by the 105-nation non-governmental International Solar Energy Society, is being held in Africa for the first time in 41 years.
