Kites can be used to harvest wind energy with substantially lower material and environmental footprints and a higher capacity factor than conventional wind turbines. In this paper, we present measurement data from seven individual tow tests with the kite system developed by Kyushu University. This system was designed for 7 kW traction power...

A submerged floating tunnel (SFT) can be a promising solution for crossing a deep or wide waterway. This tunnel concept will consist of an immersed tube, either attached with anchor cables to the seabed or attached to pontoons floating on the water surface. The reliability of the tether-stabilized SFT is assessed in this research. A suitable...

Kites can be used to harvest wind energy at higher altitudes while using only a fraction of the material required for conventional wind turbines. In this work, we present the kite system of Kyushu University and demonstrate how experimental data can be used to train machine learning regression models. The system is designed for 7 kW traction...

This study presents the results of small scale flume experiments on a submerged rectangular cylinder subjected to a current, regular wave and combined wave-current environment. The objective of the study is to gain more knowledge about the hydrodynamics around and the kinematics of a submerged structure, to give a contribute to the research...

Pumping kite power systems are a promising way of harnessing clean energy from high-altitude winds. A large kite flies crosswind developing a strong pulling force through a tether which is connected at the ground to an electrical generator. The power output of such innovative systems is directly related to the wing aerodynamic properties which...

Recent years have seen a steep increase in research being performed towards active space debris removal: space debris has proven to be a very real threat to operational spacecraft, and studies indicate that the frequency of collisions will only increase if nothing is done to remove large pieces of debris. In particular, ESA has done studies...

Space debris is becoming an increasing problem requiring a low cost propulsion system capable of disposing non operable satellites and spent rocket stages. To this end electrodynamic tethers have been proposed as a viable alternative to conventional propulsion. Aside from a de-orbit system electrodynamic tethers have a wide range of applications...

Space tethers are cables that connect satellites or other endmasses in orbit. The emptiness of space and the near-weightlessness there make it possible to deploy very long and thin tethers. By exploiting basic principles of physics, tethers can provide propellantless propulsion and enable unique applications such as the provision of comfortable...

Single-molecule techniques continue to gain in popularity in research disciplines such as the study of intermolecular interactions. These techniques provide information that otherwise would be lost by using bulk measurements that deal with a large number of molecules. We describe in this report the motion of tethered DNA molecules that have been...

Visser, P.J. (author)
Please note that only this summary is in english. The rest of the report is in dutch only. This paper deals with the wave propagation of harmonic travelling waves through an incompressible, Newtonian fluid contained within an elastic tube with homogeneous and isotropic wall material. In particular the next questions are considered: 1) What is...
