The assessment identified a key question about the quantitative risk of long-term low-level microwave exposure from space-based solar power but did not answer it.

Plain English Summary

Summary written for general audiences

The report states what is known, uncertain, and unknown about the Solar Power Satellite concept of collecting solar energy in space and delivering it to Earth for baseload electricity. The Concept Development and Evaluation Program aimed to develop an initial understanding of the technical feasibility, economic practicality, and social and environmental acceptability of the SPS concept by the end of 1980. A reference system was defined using a 2.45 GHz microwave beam with a power density of 23 mW/cm2 at the center and 0.1 mW/cm2 at the exclusion zone fence line.

Quick Questions About This Study

The assessment aimed to develop an initial understanding of the technical feasibility, economic practicality, and social and environmental acceptability of the SPS concept by the end of 1980.
The reference system used a 2.45 GHz microwave beam with 23 mW/cm2 at the center and 0.1 mW/cm2 at the exclusion zone fence line.
The program scope fell short of answering the key question about the quantitative risk from long-term exposure to low-level microwave energy on public health or ecological effects.
The rectenna design permits about 80% of sunlight to pass through, which may allow multiple uses such as agriculture at the site.
