@GATC: Good sci-fi material doesn't have to be excessively complex or creative, but it needs to be plausible. Tokamaks, ion/plasma propulsion, and plasma-armature rail-guns are perfectly valid sci-fi material. Make it easier on yourself.

Spoiler!
1). Helium has an extremely (as in very tiny) small neutron cross section; you would have to shoot somewhere around 10^14 neutrons at a single Helium atom to have any real chance of splitting it. Even if you could somehow increase the neutron cross section of Helium, splitting it would still be counter-productive. Fission relies on the potential energy gap between the initial nuclei and product nuclei. The potential energy gap between the initial nuclei and its fission products is large when you have unstable elements, like U-235 (The most common Uranium isotope used in fission reactions). However, this energy gap is very small between Hydrogen and Helium (Even H and He isotopes), making fission useless as an energy source. In addition, helium isotopes don't even have the ability to form neutron pairs, preventing a chain reaction from happening. (This means that you have to constantly bombard the fuel sample with neutrons). Besides, fission actually converts a small portion of the element's mass to energy, so unless this "Psy Power" violates E=mc^2 AND the laws of thermodynamics, you will lose energy per cycle. By the way, fusion can generate reasonable amounts of energy until iron, so there's really no reason to split helium in the first place.
2). The fact that your "hard light" exerts force at all almost certainly means that its mass is >0, since normal photon pressure is too weak (as detailed in the last post) to be noticeable. Having "massed" photons would mean one of two things:
a). Your photons no longer travel at true C, making them redundant. Accelerating a beam of charged particles would be far more efficient.
b). Your photons have mass, but travel at true C, meaning they have an infinite amount of mass and energy. Since p(momentum)=mass (m) * velocity (v), propulsion via massed photons would generate an infinite amount of momentum, which would mean that your ship also travels at C. Besides making Einstein angry, this would also mean that your ship, (or your engine, rather) will undergo a very large acceleration. It is likely that the engine block will go straight through your ship, probably vaporizing it in the process.
c). Make it easier on yourself and use a ion/plasma drive.

This describes the geometry of the warp drive, relative to time, which is constant. Most of the other variables in the equation are factors, meaning that they are substitutes for functions. (aka..Lorentz factor)
