A wiperless windshield is a windshield that uses a mechanism other than wipers to remove snow and rain from the windshield. The concept car Acura TL features a wiperless windshield using a series of jet nozzles in the cowl to blow pressurized air onto the windshield.
Half sibling A half sibling (half brother or half sister) is a sibling with one shared biological or adoptive parent. A half sibling that shares the same mother (but different fathers) is known as a uterine sibling, whereas one that shares the same father is known as an agnate sibling.
On the other hand, step siblings are related by the parents marrying. There are people who consider that there is no difference between a step sibling and a half sibling. However, that is not true. As we have already shown, the difference between step siblings and half siblings lies in the way the siblings are related.
