While we’re on the subject of crap, we might as well mention the
electric pig (a.k.a. the “electric mole”), a German-made robot that’s apparently in high-demand in Europe. It’s being used as part of the more cost-effective, environmentally-friendly practice of solar-drying sewage. The effluent is spread out inside of large greenhouse-like sheds for the sun to dry it out. The “pigs” go to work, stirring the “mud” to hasten the drying process. Once dried, the resulting material is virtually bacteria-free and can be more safely spread on farm-fields.
