Besides the already successfully introduced usage of offshore wind energy and tidal energy within the ocean, other resources remain unused. Especially the marine energy sector has seen huge growth in the last years due to the oceans enormous amount of untapped energy potential. The demand of modern societies and the ongoing fight against climate change forces us to search for new renewable and environmentally friendly energy generation methods ( Enerdata, 2021). Globally the consumption of energy has nearly doubled since 1990. The development and growth of modern societies has emerged a rise in the demand for energy within the last decades. Therefore the paper mainly focuses on the design and construction process, up to the production of the TUSK. Due to Covid-19 regulations it was not possible to test the prototype. This provides a fully autonomous ocean current power plant, which communicates in real time data and has a promising outlook in efficiency, regarding to the state of art. In addition the tracking-system was redesigned, communicating by modulation over the power line. To achieve this circular flight movement without twisting the electrical cable, a swivel and a stress reducer were designed and built to connect the TUSK as well as transfer electrical power to land. A wing which would adjust itself in the current and follow the predefined circular path, was designed using numerical simulations. With the second prototype the aim was to build a more sophisticated system, which would make the active steering redundant and use more efficient, circular flight paths. It was equipped with active steering and several on board sensors. The first prototype was build as a prove of concept. In the following paper we present the general setup and design of our first and second prototype. The wing drags the turbine through the water in a certain trajectory, sweeping a large area at a relative speed that is several times the actual speed of the underwater current. This tethered undersea kite (TUSK) consist of a wing to which a turbine is attached. Inspired by state-of-the-art technology, a unique system for current energy, the Current Kite, is presented in the following paper. Apart from waves, thermal and salinity gradients, currents are an abundant and reliable ocean energy source. Under these circumstances, more attention is drawn towards the development of non-intermittent ocean energy systems. With the global effort to eliminate conventional energies to stop the anthropological climate change, the demand for reliable and predictable renewable energies is growing. So far the demand could be satisfied by a mixture of conventional and renewable energies. The global energy consumption has been on the rise since the last industrial revolution and continues to be.

Not enough boredom-busters? If the kids in question are more into crafts than activities, we have suggestions for all kinds of crafts for kids in every season, including summer crafts for kids, fall crafts for kids and winter crafts for kids (and also projects for holidays like Thanksgiving, Halloween, Christmas, Easter, Mother's Day and Father's Day). But most of all, they're designed to be fun, which means they'll get so lost in their projects that they'll forget they were ever at a loss for something to do to begin with. They're designed to get kids to use their creativity and imaginations, or get them up and active, or have them practice certain skills like matching or memory or some combination of all of the above. Most of them only require materials that are probably already somewhere around the house (though you might have to supplement with a specific art supply or two). The phrase parents dread the most comes in a short, two-word statement, but it packs a gut punch: "I'm bored." Those words can come at any time, at any place, no matter how many toys they have or no matter what the screen-time situation is.īut parents don't have to fear boredom any longer with this list of the best activities for kids in 2022, meant to cut ennui off at the pass.
