Note that it’s a qualified claim: 3x as efficient as the “average propellor of a small boat”. The tech looks awesome in the video though, would recommend giving it a watch.
Yes, mesmerizing how it moves quickly across land and in snow and water as well, I wonder how much faster such a propulsion design could be optimized to move, and why it has not been explored more for full size off-road vehicles etc. I wonder if it's the actuator/software control system that is easier to build now, as it looks like that is where the magic is in moving efficiently in the water, and on land.
