Abstract: A dual axis tracker is a solar collecting device with fully mobile panel arrays that can be fully rotated 360° and tilted from a 90° position to a 10° position relative to the earth and is easy to maintain and operate. This device has a base support followed by a stable lower column attached thereto and a movable or rotatable upper column that permits full rotation located thereon. This permits the full rotation. A motorized jack is employed to tilt the panel array from the 90° position to a 10°. Since the array is held higher off the ground by a longer lower column, such vertical positioning is achieved in a better manner than prior art devices. Because of these movements more power can be produced in a given amount of time than prior art devices. In addition, during periods of snowfall, this device can collect more radiation off the accumulated snow cover that will surround the device thus taking advantage of said radiation to produce even greater power than previously possible.

Abstract: Unstable ground is found in many situations in many locations around the world and causes such locations to be unsuitable for building without further support or stabilization. Unstable ground, such as landfills, can be used for beneficial purposes as opposed to laying dormant. A segmented ballast base support structure according to an embodiment of the present invention can be configured to support free-standing structures, such as solar power collection systems and wind turbines. The segmented ballast base support structure can be deployed at unstable ground sites without digging or expensive filling stabilization techniques. Segments of the base support structure can be precast at an offsite location and transported to a site in segments and sections. The segmented base support structure allows for a cost effective solution to digging, as well as an easier method of shipping and transporting structures that would otherwise have to be built on site.
