the Office of the Assistant Secretary for Conservation<br />

and Renewable Energy. ORNL work on the ECUT<br />

Materials Program will complement the work we are<br />

doing for the Office of Industrial Programs on<br />

Materials for Waste Heat Utilization in industrial<br />

processes, as well as that for Buildings Energy Sci<br />

ences for the Office of Buildings and Community Sys<br />

Solar Energy (EB)<br />

The solar energy program at ORNL focuses pri<br />

marily on laboratory and field studies on biomass pro<br />

duction and harvesting, biotechnology, and photovol-<br />

taics. Additionally, we conduct research efforts on<br />

wind energy, passive solar structures, ocean thermal<br />

energy conversion (OTEC), and community planning<br />

for alternate energy use. Our effort in the solar<br />

energy program is expected to decline in future years<br />

as DOE cuts its funding support for solar research.<br />

Last year under the sponsorship of the Solar<br />

Energy Research Institute (SERI), we initiated pro<br />

cess application studies in (1) the use of lasers and<br />

ion implantation in photovoltaic (PV) cell manufacture<br />

and (2) the light-induced splitting of water using<br />

extracted green plant matter (chloroplasts). A com<br />

panion study on water splitting using live algae is<br />

sponsored by the Gas Research Institute (GRI).<br />

The Short Rotation Woody Crops Program,<br />

managed for the Biomass Energy Technology Division<br />

of DOE, consists of basic R&D in the areas of<br />

production and harvesting techniques. Nineteen<br />

universities, two USDA laboratories, a public utility,<br />

and three consulting organizations currently partici<br />

pate under ORNL coordination. The major activities<br />

under the program include species screening; stand<br />

establishment; cultural treatment and harvest; and<br />

collection, transport, and storage of woody materials.<br />

We hope to continue our research on the potential<br />

use of biomass as a chemical source and to continue<br />

our role with the USDA on-farm applications pro<br />

gram. The OTEC Program combines contract<br />

management and in-house work on the development<br />

of alternate (sea water-based) cycle concepts and<br />

evaluates heat exchanger designs for direct cycle con<br />

cepts. Passive solar building studies include data col<br />

Scientific and Technical Activities 23<br />

lection for analysis of an earth-sheltered, passively<br />

heated structure; use of foliage in cooling structures;<br />

and the development of reflective insulating blinds.<br />

ORNL continues to assist DOE in the technical<br />

monitoring and evaluation of PV demonstration pro<br />

jects. These now include facilities at Georgetown<br />

University (in the design stage); Northwest Mississippi<br />

Junior College (under construction); and Mississippi<br />

County Community College (undergoing shakedown<br />

tests). The new ORNL facility for studying atmos<br />

pheric contamination effects on PVs is nearly com<br />

plete; studies will begin in <strong>FY</strong> <strong>1982</strong>, if DOE funds<br />

are available.<br />

Geothermal Energy (AM)<br />

Our concentrations in geothermal energy have<br />

been the development of high-efficiency heat<br />

exchangers, the problems of heat rejection from<br />

power plants, and the preparation of environmental<br />

statements and analyses. We anticipate that the<br />

activities in this program will be decreasing in future<br />

years.<br />

Engineering R&D (AM 10). Currently, we are<br />

studying heat transfer and power conversion systems,<br />

placing emphasis on experimental and analytical work<br />

on heat rejection systems as the work relates to<br />

geothermal power plants and the direct use of geo<br />

thermal heat. The thrust of our work is toward scale-<br />

up and field demonstration of enhanced condensation<br />

heat-transfer technologies developed at ORNL and<br />

analysis of the problem of water resources and cool<br />

ing. This will be followed by work focused on the<br />

technology assessment and research required for<br />

selecting advanced heat rejection system components.<br />

Environmental Control and <strong>Institutional</strong><br />

Studies (AM 05, AM 15). Work in the Environ<br />

mental Assessments Project focuses on preparing<br />

environmental assessments, environmental impact<br />

statements (EISs), and other environmental documen<br />

tation for specific projects and facilities and assisting<br />

in developing and evaluating agency environmental<br />

policies associated with the DOE Geothermal pro<br />

grams. This effort requires ORNL to issue and<br />

manage subcontracts with industry and consulting<br />

firms.
