Brilliant concept, but will it work?

[Low-Q]

I was asked to put in a message from #magneat, as he for some reason got a moderator message when he tried to post here.
Just so everybody knows:
I have not put in any moderations to this thread. Every contribution and questions are welcome.


Here is the message from Magnetman:
"Hello everybody !
As I see the device - 2 disks, located at some angle to each other.
Each disk rotates on its axis.
N pipe pairs are fixed between the discs.
In each pair of pipes one slides inside the other through the ring seals (minimum - 2) with minimal friction.
From the other end these tubes are SEALANT, and fixed through the ball joints on their disks.
All pairs of pipes are connected together by flexible tubes for free flow of air - the pressure in all pipes is constant.
This design does not need side walls - it just needs to be immersed in water.


with respect."

Nice to see you thinking old friend. What filament are you using for the bellow?


Also agree with Magnetman's comment to connect the bellows's to each other on the the other side of the wheel so the whole thing can be submerged.

Thanks mate :-)


The bellows are printed in a flexible material that I bought on ebay. Works great for small go-pro camerahousings for drones as a soft "rubber" protection, but it is a little stiff and resistand for bellows. I need to change the shape a little to make it more flexible in length, and stiffer in the diameter. I also have an even more flexible filament. Nearly as flexible as silicone, but that filament is very very slow to print with. As the feeding motor easily will bend the filament before it goes into the heated nozzle, there must be very slow feeding to push that filament out of a 0.4mm nozzle. I can try that, but it takes 3-4 hours to print a small model.

Many concepts flows throug my mind. Here is another approach that might be useful as a "normal" gravitywheel or as buoyancywheel.


The light blue parts can be steel springs or hollow tubes.


The arched shape is, because of the angle of the wheels, forced to point forward/horizontally, where there is least tension.
The green parts is attached to the wheel with bearings.
The orange/red parts is hinged to the green parts so the flexible light blue parts can make an arched shape corresponding to where on the wheel they are.
The yellow arrows indicates the axis for the two wheels.


The idea is to make an effortless distribution of mass around so one side is (not heavier) generating more torque than the other side.
How effordless it is, I can't tell before it is built and tested. Because all we "know" is that mass that goes up and down the same distance cannot generate energy.
I just want to learn - the engineering way :-)

Edit
I see you added an image while I was plunking

comment below not for Image [but does raise a displacement question [same lift potential in image collapsed or open ??]
------------------------------------

The big squeezy hand of pressure is omnipresent
a bellows in the pressure hand wants to collapse with depth.. yes
but will not reopen when you want  it to refill with air regardless of ambient vents

the vents must over come the pressure hand to force him to open his grip
they must be under air pressure [linear with depth]

overcoming linear to depth pressure issues are huge energy suckers...


sorry if I am not understanding your path forward [your work around for balloons or bellows]

one thing too[I know it can be engineered around]
Floppy saggy bellows will hoop up with buoyancy .
internal support chassis ?

Delve Spectrum's original design avoids this but ??
here again for newcomers
