In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.

The Moller Skycar is a prototype personal VTOL aircraft a “flying car” called a “volantor” by its inventor Paul Moller. Its proposed features would include 275 mph (442 km/h) cruise speed, 375 mph (603 km/h) maximum speed, eight redundant, low-emission Wankel engines for safety, residential garage size, fuel consumption like a big car, a parachute for the whole machine and road capability for short distances (to be driven to a vertiport). Although current plans call for use of alcohol fuel, cheap, lightweight fuel, such as liquid hydrogen, could be used as an alternative to gasoline, as in the Mazda RX-8 Hydrogen RE, although the lower energy density will limit range.
