Flotor
Motor driven by floatation. | |
This is a very lightweight motor. It is mostly hollow and
submerged in a tank of water. When air fills an inflatable
bladder
it floats to the top and surfaces above the water line, in another
part of the cycle a deflated bladder is submerged because it
sinks
when empty. These two components
counterbalance eachother.
When the inflated bladder is pulled into the water as the
deflated
bladder fills with air, the inflated bladder deflates as it presses
against the surface of the water. When the once inflated
bladder
is flattened and empty of air, the once deflated bladder is
inflated
and just below the surface.
The now deflated bladder sinks below the surface and the
inflated
bladder floats above the surface. The motor is powered by the
rocking of a boat on waves which cause bellows on the water
line
to force air through the motor.

This has the potential to be expanded into a subnautical hullaballoon. |
|
| |
Right, well quasisubnautical If the floats have to surface
like the hullabaloon balloons. |
|
| |
What is the energy input? The waves? |
|
| |
What is the energy output? |
|
| |
If you can use the waves to give mechanical power to the bellows, why not cut out the bladders and make that mechanical power the output? |
|
| |
This converts that energy to rotational motion. |
|
| |
The way I see it the float can't sink with air inside, so it
gets squeezed on the surface of the water, pushing air into
the empty bladder which increases the force to sink
applied on the former by leverage. |

You got a vote for the name. I think Flotor was one of Skeletor's buddies; pals with Beastman and Spikor, hitting on Teela, all that. |
|
| |
But re the device - a diagram would help me. I am envisionally impaired. But I like anything "subnautical" because it could be on American TV. |
|
| |
Ok this is a edging little too close to a prototype I am working on. Since it's so close I'll give you a hint; use the bladder or lose the bladder. (+) |

Here's an example implementation contrived to make sense of this: |
|
| |
Rather than a typical set of bellows that might end up having moving components in or near the water, you could make a wave powered air pump with one or more buckets inverterted partially below the water surface. An air hose with a check valve is attached to the bottom of each bucket (now the top since they are inverted). You could send this air to a standard air motor, but maybe this flotor could be slightly more robust with salt water spray in the air supply. |
|
| |
Yes that makes sense. So the water-bellow inflates the bladder at the 7 o'clock position, while the one at 3 o'clock has its valve open to vent to the atmosphere. |
|
| |
Actually I think you need 5 bladders minimum. |
|
| |
A google search for wave powered boat comes up
with 2.5 million results. No bladders are involved,
though. |
