Expensive, difficult, slightly dangerous, not particularly effective... I'm on a roll.

Pontoon Water Runner

Okay, final idea to be able to run on water.

It's basically a cross country ski exercise machine with parallel pontoons that slide forwards and backwards on rail attachments relative to each other, each one having fins that open when pushed backwards and close when moved forward.

It's steered by handles like ski poles or a bike style handlebar arrangement attached to rudders located under the pontoons, fore, aft or both.

This system would be extremely efficient and should be able to break any speed records for man powered water vehicles by several times over.

Closest thing I found. https://www.youtube...watch?v=lDUudocjaJw

Okay, mostly baked at 7:15, but not perfected, in fact pretty flawed. https://www.youtube...watch?v=R8f5fehB_CQ
Mine would be an improvement using a steering wheel and automatically resetting pontoons. [doctorremulac3, Jul 06 2024]

       Hmm, wonder how collapsible this could be if you could deflate the pontoons. For the structural element needed you could have collapsible poles, platforms or something.   

       I also think I'd play around having springs that reset them after you push them back so you're only putting energy into pushing them backwards like actual running, albeit with more force needed obviously.

       Okay, 90% baked but needs what I added to make it fun, the central control column you push against and steer with and the spring reset so you don't move the pontoons back in place manually, and most certainly getting rid of the paddles that make the whole thing a balancing act.   

       Quite simply the prior art doesn't look fun at all. All your energy is spent keeping your balance. Mine you just lean forward and start kicking. There's one that has little paddles but mine was much more paddle area and should go much faster.

       //break any speed records//
Umm, no. Basically, anything pedal-powered will beat anything "stepped". Bicycle vs. runner?
Top cross-country skiers might hit 15mph; current record for pedal-powered boat is (a surprisingly low) 21mph (air-prop hydrofoil). Water is way more draggy than snow...

       I'm seeing that the fastest water thing is the deal you jump up and down on with a couple of fins in the water.

       Like a Waterbird Aquabike? 17mph, according to a re-seller, but that would be really pushing it (a friend of mine has one).

       Cool! I want one!
