Help me generate a picture showing some efficiency-related elements. The overall tone should be bright, and the style should be futuristic and technological. These elements are scattered around the picture. I don't need any dark-toned elements. There needs to be a white space in the middle of the image, about half the width and one third of the height --relax --aspect 4:3 --version 5.2 --quality 2 --stylize 250
