"Harder problems make for better invetnions." He adds that tight
constraints spawn better inventions. Spin vs flutter.
He points out the large difference between flat-like flutter of a belt
and a torisional flutter; he was favoring the flat belt flutter that
could drive the up and down magnets set on near the belt ends. Scaling
up brings the sound challenge. Wind cut-in speeds. Shape of
belt had not been explored much. Mass of belt? Mass of magnet?
Challenges of scaling up persist. Spanning extant structures (window
frames, mountains siding valleys, etc). Use protected first-world
applications to help fund third-word distribution.

Study on vibrational electric generator with
impedance control

Abstract:
This paper presents theoretical analysis and design method of a linear
vibrational electric generator that converts kinetic energy of vibration
into electricity. The generator is intended for applications such as
supplying electricity to sensors or small information devices that must
function without batteries for a long period of time. The generator is
modeled as a one-degree-of-freedom vibration system. It is shown that
the maximum output is attained when the generator is vibrating at its
resonant frequency and at its mechanically movable maximum amplitude.
The vibration amplitude is controlled by changing the electro-mechanical
damping of the vibration system. The experimental system consists of
three stationary generator coils and a moving permanent magnet unit
suspended by leaf springs. A micro controller monitors the generator
output and changes the connection of the generator coils to adjust the
electro- mechanical damping to maximize the generator output. This
system generated power of 100mW with 29% efficiency when external
vibration of 6Hz with 5mm(p-p) amplitude was applied.

Aeroelasticity#Flutter
Some questions
- How does the WindBelt generate electricity? Scale?
Micro-WindBeltTM
to large tower-held belts?
- Has a kite system incorporating a WindBelt demonstrated making and
use or storing electricity?
- What patents seem to relate to the method found in WindBelt?
- Are there already scientific instruments or marketed products that
use the wind or fluid flow to vibrate belts, ribbons, strings, etc. with
the purpose of generating electrical signals?
- Has aeroelastic flutter been used in transducers? Has flutter
oscillation been at the core of electric production in any prior scenes?

ELECTRICAL
MUSICAL INSTRUMENT Benioff
Patent number: 2239985
Filed: Aug 12, 1938
Issued: Apr 1941
When a musical stringed instrument's strings are vibrated and the
mechanical vibrations are converted to electrical signals for
broadcasting, then how close is such matter with the WindBelt?
- Electromagnetic transduction? Where has this principle
been applied?
- Rotary Ribbon kites simply rotate. This is not the aeroelastic
flutter involved in the WindBelt.
- Ribbon and wriggle tensional wings that flutter derive electricity
via means different from the WindBelt. Discuss.
- Frayne's insistence that for the very small "there
is no other small wind power" ...than WindBelt---- will be a fun
challenge. The flapping
of a bee's wings were once thought insufficient for carrying the bee.
All are invited to discuss this challenge.
- There are non-WindBelt ways to use aeroelastic flutter to collect
energy and to make electricity.
- Proposition: The mechanical principles used in WindBelt were
taught in earlier patents. Open for discussion. Using vibrating strings
and diaphragms fluttered by moving air to generate electricity seems to
have been the working principles taught in earlier patents and products.
Explore music, sensors, transducers, telephone,
- The alternating current (AC) is rectified to give a direct
current (DC) for applications.
- Dave Santos has already been long investigating airfoil shapes for
flutter Sputnik wings that work omni-directionally with derivation of
electricity by various means. Also his flipper wings are in this realm.
Discuss?
- Wobble
- Ribbon microphone Dynamic mics or
microphone.

the affect of moisture on the vibrating ribbon element.
Consider also the affect of temperature changes, altitude pressure,
solar radiation, UV damage, stretch, dynamic tensioning, smoothing of
gains,

The response of turbulent flow to the disturbance of a vibrating ribbon
- quoting from
http://www.humdingerwind.com/management.html ::
Shawn is the inventor of the core wind generator technology on which
Humdinger is founded. Previous to his involvement with Humdinger, Shawn
successfully matured two technologies, in the fields of "green"
packaging and water disinfection, from concepts into developed products
in pre-production. He established a strong intellectual property base
surrounding those technologies and in early 2006 sold substantial rights
to a Fortune 500 company. He is presently involved with refining the
manufacturing processes of those products in facilities that have been
built overseas.
He is also part of an on-going effort established four years ago at
the Massachusetts Institute of Technology to develop low-cost
technologies by which entrepreneurs in Haiti can transform agricultural
wastes into saleable cooking fuel.
Shawn has six pending U.S. patents. He has his Bachelor of Science in
Physics from the Massachusetts Institute of Technology.

Sensors with oscillating elements
- Institute of Physics (IOP) Author guide:
- "Articles should not:
- present new but trivial and obvious results
- make unsubstantiated conclusions
- bury new results beneath too much
scene-setting and recapping of findings already published
- present incremental research "
- What is known about oscillating ribbons as signal generators? Early
published notes on vibrating-ribbon signal generation?
- What is new in Humdinger, Inc.'s. offering in the
WindBeltTM
? Discussion is open.
Is there any new physics?
Is there new application?
Is there new ornamental design of former same-duty device?
- Show carefully the distinction between these:
Santos Flipper, Santos Sputnik, VAWT, VAWT ribbon, Skybow ribbon,
unidirectional rotary Magnus effect turbine, wind-oscillated ribbon
generator with ribbon holding conductor, wind-oscillated ribbon
generator with ribbon holding magnet, skyhooked Santos oscillating
wings, ribbon rotor (Roeseler), oscillating diaphragm signal generators,
Wind Dam, etc.
Essays
are invited.
- Could the ribbon be the conductor while the permanent magnet is off
the ribbon instead of the magnet riding on the ribbon? Perhaps
near the ends of the ribbon, the ribbon could have coiling conductors
that feed into and then out of the ribbon at the end; the oscillating
coil would vibrate between magnet heads. Discuss.
- Where in kite systems would signal-generating vibrating ribbons
be placed? Purposes? Size?
- Noise-making oscillating ribbons are cousins to electricity-making
oscillating ribbons.
