Elastic energy storage in primary feather shafts.
It is proposed that the kinetic energy of a pigeon's wing, in hovering or slow forward flight, is transferred to the air at the end of the downstroke by a mechanism involving temporary storage of additional energy in bent primary feather shafts. Estimates of the amounts of energy which can be stored and recovered in this way are compared with the requirements of the theory. The hypothesis is no...
متن کاملSustainable Development of Abandoned Mine Areas Using Renewable Energy Systems: A Case Study of the Photovoltaic Potential Assessment at the Tailings Dam of Abandoned Sangdong Mine, Korea
As mineral resources are depleted, most mines are typically abandoned and left unattended, resulting in serious social problems that impede sustainable development of these areas. The mining industry has recently introduced the use of renewable energy systems to solve the problems. This study assessed the photovoltaic (PV) potential of an abandoned mine tailings dam at the Sangdong mine in Sout...

متن کاملDamping of Torsional Resonances in Generator Shafts Using a Feedback Controlled Buffer Storage of Magnetic Energy
The power and energy for ASDEX Upgrade, Germany’s largest experiment for nuclear fusion research, is provided by three separate networks based on flywheel generators. Damage at couplings of the shafts of the flywheel generators EZ3 (144 MVA / 500 MWs) and EZ4 (220 MVA / 600 MWs) were discovered during a routine check. They can only be explained by subsynchronous resonances (SSR) which are excit...
