An Alcubierre metric is a form of spacetime metric, a speculative idea by which a spacecraft could achieve faster-than-light travel if a configurable energy-density field lower than that of a vacuum could be created.
THE METRIC SYSTEM WONDERLAND or THE WONDERS OF THE METRIC SYSTEM
There is 1 metric ton in a metric ton of clay. The metric ton is a unit of mass equal to 1,000 kilograms. So, a metric ton of clay weighs 1 metric ton.
Metric.
Bushels are a unit of measurement in the English system, not the metric system.
Metric measurement is measurement made using units as defined under the metric system.

An Alcubierre drive is a hypothetical means of faster-than-light propulsion, based on the controlled contraction and expansion of surrounding space.
Inocencia Alcubierre died on August 12, 1930, in Barcelona, Catalonia, Spain.
An Alcubierre drive is a hypothetical engine which is capable of faster than light travel by enveloping the spacecraft in a bubble of curved spacetime. This shell is allowed to travel faster than light, the spacecraft moving less than the speed of light inside the shell. The drive does require the existence of a type of exotic matter; matter with an imaginary mass. Such matter has never been observed and is considered highly speculative.
Yes, the Alcubierre Drive relates to a solution to one of Einstein's field equations in his General Theory, although the solution itself does not imply that creation of the drive itself would be a practical endeavor; it remains in the realm of theory.
I'm not sure that it's possible to answer the question in any meaningful way. Under the Alcubierre metric, what matters is the speed of propagation of the Alcubierre ring/bubble; anything in it is really just "carried along for the ride". It's likely largely irrelevant anyway, since the energies required appear to be enormous (many orders of magnitude more than is in the entire universe to create a bubble large enough to transport anything of significant size). This is not just a minor technical problem that could be overcome by futuristic energy production methods, this is saying that converting the entire universe to energy, should we somehow be able to do that, would not be enough.
Since the Alcubierre drive would require exotic matter and specifically matter with a negative energy density, unobtanium might be a perfect fuel (presuming that its a consumable) given the significant overlap of a theoretical material with such a broad definition.
