    Abstract: The new methods for treating green wood discuss herein speed up air drying of common green wood, including both softwood and hardwood. This method involves treating and altering the green wood with a base solution, and subjecting the wood to an air drying process. The new methods require less time to dry the green wood to a desired water content. In addition, other additives may be included in the base solution such as miscibility solvent(s), preservative(s), solubilizer(s)/stabilizer(s), chelating agent(s), bonding agent(s), pigment(s), UV protective, anti-oxidant, anti-fungal, anti-microbial and/or anti-insect chemical(s). The base solution solution may also slow down the wood deterioration caused by physical, chemical and biological sources under ambient conditions.

    Abstract: According to some embodiments, the present invention provides a novel photovoltaic solar cell system from photovoltaic modules that are vertically arrayed in a stack format using thin film semiconductors selected from among organic and inorganic thin film semiconductors. The stack cells may be cells that are produced in a planar manner, then vertically oriented in an angular form, also termed herein tilted, to maximize the light capturing aspects. The use of a stack configuration system as described herein allows for the use of a variety of electrode materials, such as transparent materials or semitransparent metals. Light concentration can be achieved by using fresnel lens, parabolic mirrors or derivatives of such structures. The light capturing can be controlled by being reflected back and forth in the photovoltaic system until significant quantities of the resonant light is absorbed. Light that passes to the very end and can be reflected back through the device by beveling or capping the end of the device with a different refractive index material, or alternatively using a reflective surface. The contacting between stacked cells can be done in series or parallel. According to some embodiments, the present invention uses a concentrator architecture where the light is channeled into the cells that contain thermal fluid channels (using a transparent fluid such as water) to absorb and hence reduce the thermal energy generation.
