Abstract: The present invention includes a vertical axis wind turbine apparatus including a spindle tube connectable to a permanent foundation such that a spindle axis is oriented substantially orthogonal to a surface upon which it is placed, such as the ground or other stable surface. The apparatus described herein also includes a rotor disposed at least partially within the spindle tube and rotationally engaged therewith such that a rotor axis is oriented substantially parallel to the spindle axis. The apparatus can also include a truss system extending radially from the rotor and a blade assembly movably connected to the truss system and adapted for rotation about the spindle axis and the rotor axis. The truss system functions in part to permit rotation of the blade assembly while increasing the swept area of the turbine and thus the resultant energy capture.

Abstract: A method of producing a concrete container for storage of radioactive waste includes the steps of providing a double-walled mold with an inner and an outer wall, the mold being open at the top and having an interior for receiving the radioactive waste. The space between the inner and the outer walls is filled with fibers. Subsequently, a concrete mixture is filled into the space between the inner and the outer walls to a level below the uppermost layer of fibers. The interior is closed off by a cover plate. After placing more fibers onto the cover plate a concrete mixture is poured onto the fibers until they are completely covered. Alternatively, it is possible to place a cover plate onto the inner wall for closing of the interior after insertion of the radioactive waste, fill the space between the inner and the outer walls with fibers, and place additional fibers onto the cover plate.
