Fresnel lenses, however, don’t require curvature of any kind, but instead utilize concentric flat rings to diffract light, with the rings’ size and width determining the overall lens focal length.

In particular, using a Fresnel lens coupled with a laser to fuse lunar regolith would reduce the power (and thus size, weight, etc.) of the laser astronauts would need to tote along, the study finds.

Virtually all modules on the market today feature cells that have been cut into two or more pieces. Using cut cells results in a lower current, reducing power loss at the module level. Half-cell ...
