What is the difference between a grain elevator and a silo?
Judging by the fact that the articles for wikipedia and other online sources show precisely the same buildings when asked for grain elevator and silo, it would appear to be largely a difference between US and UK usage. However, grain elevator is a precise type of silo only used for grain and similar foodstuffs such as soya beans, whereas a silo can contain any pourable solids, including fuel, such as wood chips or coal.
