I just saw a tanker sytem that makes bubbles and obviously in like 30 seconds I thought well, the bubbles would be better captured from both sides, and if we go there why not just use an air cushion instead of bubbles and yes, the engines must be placed on the side for propellers to move water. And behold - there is a company that does exactly that. A hovercraft effect boat. I think something like that would improve tanker efficiency a lot.
A smart technology, which we already use on seaplanes, without using fans, using a step and creating an aerodynamic airflow sucking and guiding ram air under neath the hull.
It is a interesting idea. The main issue with this setup is will not work unless the body of water is flat calm, in terms of stability there is no difference between this and standard flat bottom boat. This seems to be just a rigid skirt hovercraft. There are several power catamaran boats that have a front skirt, designed to better trap incoming air under the hull. Power cats are designed to catch air between the 2 hulls raising it out of the water providing a smoother ride and better fuel efficiency and works in both calm and rough sea's.
I love how your design has taken absolutely no account for the surface waves or the fact that the submerged part of the hull is necessary for boat tracking and stability.
But what about all the time spent on the cool 3d modeling and video production with literally 0 real world application examples or data to support it....doesn't that count for something!? lmao
We are currently researching warp speeds above 8. We struggle to stabilize our dilithium crystals, but progress is being made every day! As to toroidal propellers, our technology is agnostic to propulsion setup and benefits in just the same way as other do. We've tried to get our hands on them to test the hype, but yet to be located. So we're stuck with our dilithium crystal project. In the mean time we're busy burning electrons every week on the fjord on a very real and proven technology. Let us know when you're in Oslo, and you'll get to measure the consumption yourself! Beam me up, Scotty!
We have several prototypes built throughout the years, proving the technology and the net energy reduction. This video shows our latest 8m leisure prototype. ua-cam.com/video/6UaDcOdnLNA/v-deo.htmlsi=wKO_IxM5yUuBnel5
@@C_G1443 The reduction of energy consumption is of course based on the total energy consumed by the vessel to move it, accounting for the fan systems energy use, as well as the cooling of batteries or other auxiliary energy consumers in the power train.
Our system has a very low overpressure in the cavity, and a fan capable of delivering enough volume of air per second to fill the total cavity volume within about 1 -2 seconds at max pressure. If you visualise a box lowered into a body of water upside down, it will trap the air that is already in the cavity. To reach the level of pressure we need to support the portion of weight desired on the air pressure we only need to lower the vessel a few centimeters. Thus, when the waves make the cavity exposed to ambient air, it will increase the mean leakage, but the cavity will not be emptied of air as we always produce an overpressure inside. The wet surface is still significantly lower than for traditional hulls. In addition, the fan system creates a damper effect on motions.
How practical would this be on a smaller vessel (6 m)? Would the air system take too much room and the fan be very loud? And is this technology only practical for electrical propulsion vessels?
The term used for this type of technology is Surface Effect Ships (SES). Hovercrafts and SES is very much related, but SES does not support its full weight on air pressure. It has hulls that carry some of the weight.
This particular video shows an animation of one of our demonstrator vessels. You'll notice that the propulsion units in this case are positioned behind the demi hulls. This ensures that no air enters the propulsions units, keeping their operation unaffected. Also, we have already built several full scale vessels and tested with different types of propulsion systems, both stern drives and single outboard.

@pascaltechnologies If it's in beta, why is there only tiny animated clips? Would air remain out of propulsion area during turns? Does it prevent undergrowth?
You don't even need a fan to pump air in. When your up on plain/ air than that creates enough wind to float your boat like a hovercraft. Air hull suspension.
Surface effect ships are actually a proven technology, and they have been used by among others the Norwegian navy in their Alta and Oksøy class ships for quite some time. Recommend looking up surface effect ships on Wikipedia.

Compared to foils, less efficient but also less fragile. Seems like a good system.
great technology
We agree!

Heard that if you pair this with a Toroidal propeller, it gets infinite gas mileage.
As always: When it sounds too good to be thru ...

@@pascaltechnologiesGreat reply!
@@pascaltechnologies That reply alone was worth a subscribe :)
Brilliant!
1:30 That's quite a bold statement. Do we have prototypes already?

This is a proven technology, it definitely works and there's already ships in operation using this, look up surface effect ships on Wikipedia.
At what speed it get activated..
How does it work in rough water ?
Bad I guess. VERY bad.

Ever hear of the Benateau air step hull.
* only works on glassy water

That should add some range!
So the same as a hovercraft?

What ever happened to hydrofoils?
What about cavitation of prop
