All ships (including the player) now have regenerative capability. Energy levels slowly restore over time; the rate of recovery is proportional to the amount of energy available.

The next major obstacle is overcoming gimbal lock; it's too obvious a problem to be ignored.

The only viable solution is conversion of the 3D orientation algorithms from Euler Angles to Quaternions, an extension of the complex numbers first studied by Hamilton in the 19th century. They were thought to be of very limited value until more recently, when their functionality as a 3D orientation system was discovered. They avoid the problem of gimbal lock completely but the tradeoff is their nonintuitive nature; it's difficult to immediately sense a direction from a given Quaternion, the way one can with Euler Angles.
