present technology
Present Technology: The dolly that is commonly used today is made of metal, with rubber wheels. ... Hovercrafts of the present have a gigantic vacuum or “leaf blower” on top and they require some sort of power unless they are powered by gasoline. ... (See Figure 3) Future Technology: In twenty years, the Hover-dolly will be used in the place of the dolly. The Hover-dolly is architecturally very similar to the hovercraft, however there are some modifications that have been made to the hover-dolly which the present hovercraft do not have. ... Therefore we must invent it and it would be a future breakthrough in technology.
