could gyroscopes be used to produce upward linear thrust? or be used to push something along at least? i was looking at an attempted recreation of teslas flying stove and i was wondering if powered gyroscopes could be placed at what he referred to as "eccentrics" to produce upward momentum and make the machine levitate. here is the site: [crackpot link deleted] a cool concept worth looking into. i am trying to figure out if such a device could be effective in overcoming its own weight, or at least producing some sort of displacement of inertia causing it to move in a straight line in some direction?
