Well, you could make your own hoverboard if you really wanted to. Check over at
http://www.slashdot.org/ and look up "Warp Drive" or "asymmetrical capacitor" which is one of NASA's recently patented propulsion systems.
Here's what you need:
1. A board, like a piece of plywood about an inch thick, one foot wide, three feet long.
2. Four (4) Asymmetric capacitors large enough to support your weight.
3. A control system to adjust the power going to each asymmetrical capcitor. Your typical light dimmer is basically what you need, but must handle significantly larger power loads.
4. A portable power source capable of providing 30,000 Volts or more for each asymmetrical capacitor.
5. Wood sticks, nails and glue to mount the asymmetrical capacitors.
6. (Optional) Thick rubber insulated suit for preventing electrocution.
Seriously guy, I've seen pictures of this asymmetric capacitor work. It's a wire (circular or triangular) and a piece of metal foil (circular or triangular) aligned so that when you are looking down at it from the top, it looks like one circle or triangle. Attach a wire from the power source to the top thin wire and another wire to the bottom metal foil, apply 30K volts, and you have a hovering propulsion system. Check Google for the websites. There are several websites that show this thing working AND THEY ARE VERY DANGEROUS. YOU WILL DIE FROM ELECTROCUTION if you're not careful.
The wierd thing about this is that no one has figured out the physics of how or why it works. The Slashdot crowd suggested this as a precursor to Warp speed because the "asymmetric electric field" is supposedly similar to the "Warp Field" generated by a Warp Field Nacelle.
