Draw a sheet of exactly sixteen very simple original building sprites for a 2D game, four rows and four columns in the order below. Use the same visual language as simple resource inventory icons: two or three solid colors per building, a few broad connected color blocks, and clear distinctive pixel silhouettes. Each building has one main body shape and one large recognizable feature. Keep its outline characteristic. Surfaces are plain solid areas. Larger buildings enlarge the body and color blocks while retaining the same low detail density. Omit bolts, seams, panel grids, vents, fine pipework, scratches, small lights, texture, gradients and realistic shading. All buildings are seen from a camera pointing straight vertically down. Only flat roof and top surfaces are visible. Every shape lies in that top plane; no visible side walls or perspective. Show only static building bodies on a transparent background, separated by clear gaps, without labels, floor tiles, cast shadows or operating effects. Final pixel density is 32 pixels per world tile, with each standalone sprite sized from its stated square footprint. Row 1, left to right: 1. Battery, 1 by 1 tiles, 32 by 32 pixels: a squat rectangle with two broad terminal tips; muted teal body. 2. Power node, 1 by 1 tiles, 32 by 32 pixels: a simple round hub with four short arms; pale gray body. 3. Water pump, 1 by 1 tiles, 32 by 32 pixels: a round housing with one offset circular port; muted blue body. 4. Cockpit, 1 by 1 tiles, 32 by 32 pixels: a clipped wedge with one large window; gray casing and dark teal window. Row 2, left to right: 5. Smelter, 2 by 2 tiles, 64 by 64 pixels: a solid octagonal casing with one dark inset plate; ochre body. 6. Compressor, 2 by 2 tiles, 64 by 64 pixels: a broad H-shaped frame with one central rectangular plate; gray body. 7. Separator, 2 by 2 tiles, 64 by 64 pixels: a plain round casing with three large wedge-shaped areas; gray body. 8. Steam generator, 2 by 2 tiles, 64 by 64 pixels: two large round caps connected by one short solid bar; muted blue-gray body. Row 3, left to right: 9. Laser drill, 3 by 3 tiles, 96 by 96 pixels: a solid triangular casing with one round center; gray body and teal center. 10. Liquid tank, 3 by 3 tiles, 96 by 96 pixels: a plain circular lid with one large offset hatch; muted blue-gray body. 11. Warehouse, 3 by 3 tiles, 96 by 96 pixels: a broad rectangular roof with one L-shaped band; ochre-gray body. 12. Thorium reactor, 3 by 3 tiles, 96 by 96 pixels: a solid hexagon with one smaller hexagonal center; gray body and muted pink center. Row 4, left to right: 13. Solar panel, 2 by 2 tiles, 64 by 64 pixels: two offset blue rectangles, each with one broad lighter strip. 14. Repair projector, 2 by 2 tiles, 64 by 64 pixels: a rounded cross with one round center; gray body and teal center. 15. Radar, 2 by 2 tiles, 64 by 64 pixels: a plain circle with one thick diagonal feed arm lying entirely in the top plane; gray body. 16. Core base, 4 by 4 tiles, 128 by 128 pixels: a large clipped square with one broad circular center; muted teal-gray body.
