Using an onboard source of energy (such as a battery, ultracapacitor, solar panel or any combination thereof), the electrodes will send an electrical current into the plasma, causing the plasma to push against the neutral (noncharged) air surrounding the craft, theoretically generating enough force for liftoff and movement in different directions (depending on where on the craft's surface you direct the electrical current).
The concept sounds far-fetched, but U.F. mechanical and aerospace engineering associate professor Subrata Roy plans to have a mini model ready to demonstrate his theory within the next year.

Is there a far fetched concept any more. Just got to read some of the ideas on astrophysics to see that science fiction writers don't have to come up with the technical stuff, just the plot and characters.
