Perpetual motion machines are a dream and a nightmare. However, if focused on the task of making the world a better place as an engineer then that is easily done as engineers are problem solvers. Example Problem - it gets cold in the winter in the northern hemisphere and people can't grow food. Solution - a farmer in Nebraska realized that the temperature at about 8 feet down into the Earth is a constant 58 degrees. So, he dug some trenches, put in piping with a solar-powered fan system (with battery backup), and now his greenhouses are a constant 58 degrees minimum no matter what the weather is outside. He has reportedly grown orange trees and other tropical plants in his greenhouses. His experience however, could be an anomaly. Interested engineers should investigate this farmer and come up with engineering parameters (size of pipe, speed and number of fans, depth of trench, trench backfill specifications for all kinds of environments for various sizes of greenhouses, etc.). This investigation/project could also be expanded to houses and even apartment buildings to reduce winter electricity bills (because the homes would never get below 58 degrees). Or, if you're not interested in that project, find another. Good luck!
