Abstract: The following series of kinetic works was designed to use moving air (wind) and moving water as power sources and to establish limits of control over them, ranging from programmed movement to random movement. Balance is naturally a crucial factor in all of these pieces as they each make use of one or more counterweight systems to assure a reaction from the piece to the action of the particular power source. "Wind Piece #1" was designed to operate with even the slightest breeze. This was accomplished by using light materials (wood and sheet steel) and applying some of the basic laws of physics in its design, namely the ones covering the moment of the force. Thus when a light breeze engages the blade, the movable portion of the piece, it is easily set into motion as the force of the breeze, is multiplied many times by the long perpendicular distance from the top of the blade to the axis. This piece utilizes the knife type pivot which is virtually friction-proof, but at the same time limiting as to the amount of swing possible. In this case it is less than 100 degrees.
