I learned about the bias drive a few weeks ago. Actually I first saw the term in Hannu Rajaniemi's Invisible Planets, but I thought it was just something he made up until very recently. No. Turns out it's for real. David Darling has this to say:


"The bias drive would alter the properties of space itself. It could reduce normal gravity on one side to produce thrust. Imagine a boat made from a block of wood with one pointed end and the other indented. The block is floating on water, and you drop detergent on it. Because the soap changes the surface tension of the water, the boat is pushed along."


Interestingly, the soap and boat metaphor appears in Liu Cixin's Death's End but there it's describing a different space drive, a sort of STL Alcubierre drive (I think).


Anyway, given that this drive works by manipulating gravity, are there other uses? Perhaps generating artificial gravity without spinning, antigravity tech, or gravitational weapons? Gravitic telekinesis? And does the bias drive have unique advantages that would prevent it from being made obsolete by other tech?

It's like a alcubierre drive but for sublight travel
