'' by Misner, Thorne & Wheeler. The principle behind it is quite simple; getting the implementation right is tricky. Essentially, two beams are crossed over and connected with an axle through their crossing point. They are held at right angles to each other by springs. They have heavy masses at the ends of the beams, and the whole assembly spun around the common axle at high speed. The angle between the beams is measured continuously, and if it varies with a period half that of the rotation period, it means that the detector is experiencing a measurable gravitational field gradient.

Vacuum Fluctuation Battery

In 1984, Forward published his theoretical design for a "Casimir battery", utilizing the electromagnetic

and the attractive force associated. The Casimir force would pull the plates together, if the plates were charged with same polarity and the electrostatic force applied to the plates is adjusted. The Casimir force will pull the plates together increasing the electric field between each plate and producing a voltage. The battery could be "recharged" by increasing the electrostatic force, pushing the plates apart.

Fiction

In addition to more than 200 papers and articles, he published 11 novels. Critics' reviews were mixed, always praising the science concepts and the aliens he created, but often finding the plots thin and the humans shallow. His treatment of hard-science topics in fictional form is highly reminiscent of the work of
