I'm envisioning a FutureBargeā¢ with the landing platform kept at constant height, built off of a barge that rocks with the sea. Obviously from the frame of the person driving the barge, the platform would appear to grow and shrink in height inversely to the motion of the ocean (lol sexjokes), but then when you tie the thing down after it lands, you can then marry the two reference frames.
I was thinking along those lines as I was watching the horizon wobble on the webcam. Large international ships have their own sort of native stabilization, but a barge, even a football field one, won't. But these days we've got buildings that can adapt to earthquakes and gloves that can handle Parkinson's. So, let's get on it.
Like almost every tech, it's only a matter of time.
