e e~~~~~~~- ticipants discussed new developments in solar power and its ecological advantages. Richard J. Schwartz, head of the School of Electrical Engineering at Purdue Univer- sity and general chairman of the confer- ence, said solar power is already the most economical way of providing electricity for certain applications, especially in remote areas. For example, it is cheaper for a farmer to use solar power to pump water for his cattle than to run electricity from a source 1000 feet away, Schwartz said. Solar-generated electricity currently costs about 10 times more than electricity generated by coal. However, the recently developed lighter, thinner, more efficient solar panels are much less expensive than the older, bulkier cells, primarily because it takes less material to manufacture them. If an environmental tax, such as the proposed carbon tax, were implemented, solar ener- gy would be even more competitive be- cause there is no cleanup cost. Morton Prince, a senior scientist with the Department of Energy's photovoltaic energy division, said that the combined output of all solar cells by the year 2000 is projected to equal the daily power needed by a city of 1 million people. Nearly trans- parent solar panels may one day be used on the facades of buildings, turning them into giant solar generators, Catalano said. Billboards and roadside telephones are already using solar panels to generate their own electricity. With the increasing envi- ronmental costs of fossil fuels and rapid technological advances in photovoltaics, the future of solar power looks bright. Drinking Raises Breast Cancer Risk Drinking two alcoholic beverages a day raises the estrogen levels in women, leading to greater risk of breast cancer, according to a recent study by researchers at the National Cancer Institute. "This is the first study to suggest that the mechanism by which alcohol affects breast cancer risk may be the increase in hormones caused by alcohol," said Marsha E. Reichman, one of the researchers wh
