Nor is it possible for me to describe in this place the mechanical marvels of the institution-the huge underground boiler-house, with its sixteen boilers; the electrician's room, clean and bright as a new dollar, with its "purring dynamos" and its immense switch-board; the tunnel through which books are delivered by electric trolley to the legislators in the Capitol, within eight minutes of the time they are applied for; and, most wonderful of all, the endless chain, with its series of baskets, whereby books are not only brought down to the reading room, but re-delivered, at the mere touch of a button on whatever "deck" of the nine-storied "book-stacks" they happen to belong to.

"The Greater Power"
Harold Bindloss W. Herbert Dunton
Many brief prose poems in literature are dynamos of emotion.
