Well also enough energy to dwarf a small galaxy. Definately an idea that
needs further development. ;)

Well there are quantum tunneling effects work at microscopic. You MIGHT be
able to make it work at macroscopic, but no solid clue how.

But saying it would take incredable amounts of energy is a big difference from
physically impossible.
