cool find
I can understand and it is a little overzealous and dramatic voiceover for something nobody really needs.
It wont change all our lives either.
In the time you rig the whole thing you can ride around the lake .... but that is not the issue anyhow...
from a engineering standpoint it is cool no doubt ....
from a safety on the water aspect : its a toy and better stays on shallow areas without any waves or any other traffic....

those speedos look awful dont they .... I have to retire mine !
