    • According to some embodiments, a drum may be submerged in water and extend horizontally along a center axis between a first point on a first side of the drum and a second point on a second side of the drum opposite the first side. Three curved vanes may be attached to the drum such that the vanes, when acted upon by a water flow perpendicular to the axis, are operable to cause rotation about the axis, wherein an edge portion of each vane, located substantially opposite the drum, defines a plane substantially parallel to a plane defined by a surface of the drum located between the edge portion and the axis. An electrical generator coupled to the drum may convert rotational energy produced by the rotation about the axis into electrical energy.
    • 根据一些实施例,滚筒可以浸没在水中并且沿着滚筒的第一侧上的第一点与滚筒的与第一侧相对的第二侧上的第二点之间的中心轴水平地延伸。 三个弯曲的叶片可以附接到滚筒,使得当叶片垂直于轴线的水流动作用时,叶片可操作地绕轴线旋转,其中每个叶片的与滚筒大体相对的边缘部分定义 基本上平行于由位于边缘部分和轴线之间的滚筒表面限定的平面的平面。 耦合到滚筒的发电机可将由围绕轴线的旋转产生的旋转能量转换为电能。

    • An aircraft is provided utilizing a spherical balloon filled with buoyant gas such as helium at a pressure substantially greater than atmospheric so that its dimensions are substantially unaffected by changes in atmospheric pressure or temperature. The aircraft may take the form of a self-propelled and self-contained airship, or may be merely a passive device for providing lift and intended to be towed by and controlled from a helicopter. The spherical balloon is mounted on a normally horizontal axle having end portions projecting from opposite sides of the balloon, and includes a rigid load supporting yoke including two arms extending upwardly from a central load supporting structure and each with an upper end suspended from the axle.
    • 使用充满浮力气体(例如氦气)的球形气囊,其压力基本上大于大气压,使其尺寸基本上不受大气压力或温度变化的影响。 飞机可以采取自行式和独立式飞艇的形式,或者可以仅仅是用于提供升降机的被动装置,并且意图被直升机牵引和控制。 球形球囊安装在正常水平的轴上,其具有从球囊的相对侧突出的端部,并且包括刚性负载支撑轭,其包括从中心负载支撑结构向上延伸的两个臂,并且每个具有悬挂在车轴上的上端。
