"The whole problem of energy sources is going to be solved by little solutions, not by some big new piece of technology that does everything. We got into this crisis by believing that we had one big piece of technology that would do everything (oil)."
- Gregory Benford

Robert Heinlein liked this term enough that he used it in his classic 1941 novel Methuselah's Children:

Had there been a bystander, he would have been startled to observe what appeared to be a standard Camden rise up off the ground as easily as a skycar. He would not have long to wonder - the car moved out over the lake, dropped down to the water and sank beneath it. Seventeen minutes later, the car rose up to the surface of a small pool of water, a pool that occupied much of the floor of an artificial cavern.

This term also appears in The Swordsman of Sarvon (1932) by Charles Cloukey:

The little skycar maintained its headlong rush for almost two hours. Then it circled down to land upon the wide ledge half-way up the cliff-side, the ledge upon which the cave opened.
