Description

The image is a diagram showing the energy efficiency of a laser-interstellar spacecraft. The diagram is divided into three sections: the first section is the energy input, the second section is the energy output, and the third section is the energy efficiency. The energy efficiency is shown as a percentage, with a value of 95%. The diagram is labeled with various numbers and percentages, indicating the energy efficiency at different stages of the spacecraft's operation. The energy input is shown as a percentage of the energy output, with a value of 100%. The energy output is shown as a percentage of the energy efficiency, with a value of 95%. The energy efficiency is shown as a percentage of the energy output, with a value of 95%.
