Creating elementary particles with energy

The one thing the Vuduri have, that we do not, is infinite free energy. They use "Casimir Pumps" to split zero energy in neutral space into positive and negative energy. They use the negative energy to create PPT tunnels which effectively bypass normal space thus allowing them to (mathematically at least) travel faster than the speed of light.

But a by-product of the Casimir Pumps is positive energy. The Vuduri do many things with it including creating electricity. This is very handy when they are in normal space, since they need a way to drive their ships forward. So they take the excess positive energy and reverse the equation e = m * c squared and use e divided by c squared to get m. In other words, they use energy to create mass. Usually these are very elementary particles, rarely organizing more than just a ball of plasma. They then force that plasma out of jets built into their ships to get forward thrust.

They aren't much for brakes. They usually just rotate their ships around and use the plasma thrusters in retro mode to slow themselves down.

Pretty cool, huh?
