A Hoverboard (Also known as Hover Board) is a fictional futuristic hovering deck, resembling a skateboard without wheels or trucks. The name is a portmanteau of the words hover and skateboard. They were first introduced in the films Back to the Future Part II in 1989, and Back to the Future Part III in 1990, where Mattel made a product branded Hoverboard. Attempts to produce the experience of a Hoverboard with available technology have involved hovercraft (or air-cushion) vehicles.
Back to the Future
There are several theories about how the Hoverboard could work. Space Magnetics (originally named Hovertech) experimented with ferrofluid force fields, attempting to ionize a column of air interacting with a magnetic fluid, forming a bubble which the board could rest on. This technology was never made to work, as the ferrofluid simply stuck to the sides of its casing when activated.
Another possible way is by use of geomagnetics, the act of repelling
against the earth's magnetic field. Such as in Back to the Future: the
Ride where each loading dock has a case containing a hoverboard, warning
us that there is a strong magnetic field. The magnets are clearly so
strong that they can reach the Earth's magnetic core that they can hover
on it by the year 2015. So far there have been no significant advances
toward completing a working device that can do this. It would require
a large magnetic repulsion, as the Earth's magnetic field is very weak.
The Mythbusters built a successful design of hoverboard using a large surfboard and leaf blowers in 2005.
Rumors circulated in 2001 that inventor Dean Kamen's new invention,
codenamed Ginger, was a transportation device resembling the Hoverboard.
In reality Ginger was the Segway Human Transporter, a self-balancing
dual electric servo, stand-up scooter.
