It seems nearly too terribly simple and straightforward to be true, a few more technical details found on the link. Though this engine, work-horse portends to be primarily a barge system, something for slowly but steadily transporting cargo en mass, if it delivers on its promise, I can imagine gondoliers—or private submariners below—punting about through urban waterways and the relaunch of thalassocracies, maritime powers that ruled the spaces between lands when it seemed that buoyancy mattered more.
