A method for cleaning a plasma reactor clamber part may include dipping the chamber part in a solvent that may dissolve a material that has been redistributed on the chamber part by a reactive plasma. A circuit board or electronic component is mounted on the contact body and the extender body. A carbon dioxide reduction system is adapted to be installed in the chamber for reducing carbon dioxide in the chamber. In another embodiment, the photodiode comprises a wafer with at least a first and a second side; and a plurality of electrical contacts physically confined to the second side, where the electrical contacts are in electrical communication with the first side through a diffusion of a p+ region through the wafer and a diffusion of an n+ region through the wafer. The present invention relates to a wind turbine support tower mounted solar system to increase the net electrical output using the existing wind turbine electrical circuits and transmission grid connection.
