 A GEV skirt occupies internal space, but that's it!  If you have a GEV skirt on the vehicle, 30% of the volume of your vehicle is dedicated to the GEV skirt.  If you're planning on building a hovercraft, make sure you pick a fairly high Density Quotient.
 ==== Vectored Thrust ====
 If a thruster of any sort can have its angle changed between forward and down, you can use it for either thrust or lift.  Building an engine like this increases its mass, volume and cost by 50%.
+===== Contragravity =====
+With sufficiently advanced technology, you can screen your vehicle from gravity, allowing it to float free.
+^  TR  ^  Mass (kg)             ^  Cost (\[ce])           ^  Power (kW)      ^
+|  +3  |  Lift \[di] 1000 + 10  |  Lift \[di] 90 + 2,500  |  Lift \[di] 450  |
+|  +4  |  Lift \[di] 2000 + 5   |  Lift \[di] 450 + 500   |  Lift \[di] 450  |
+Use your vehicle's mass, in //kilograms//, as the Lift value.  If you don't need to counter your entire vehicle weight, you can use a lower value.
+===== Levitation =====
+Technology is not the answer here;  this is straight-up cheating.  It might be magic, or some super-science material, but whatever it is, it's totally passive and simply allows the vehicle to ignore the effects of gravity.
+This material (obviously) has no mass, but will cost \[ce]100 or more (possibly //much// more) times the area of the vehicle.  The vehicle is considered to have static lift equal to its mass.
