|20090120484||Photovoltaic Tile Assembly - A photovoltaic tile assembly comprises a base tile having at least one solid region through which a mechanical fastener is driven for fastening the base tile to an underlying roof structure. The assembly further comprises one or more cover tiles each having a photovoltaic cell for converting solar energy into electricity. The cover tiles are electrically and mechanically coupled to a corresponding base tile by electrical connection posts. The posts are supported within the base tile and have a first end that contacts with and provides electrical connection with respective output terminals of the cover tile. Additionally, the first end penetrates through the cover tile to provide mechanical attachment of the cover tile to a base tile. Each post also has a second end that is electrically coupled to an electrical connection tube to facilitate electrical coupling of the cover tiles to a power management system. Tubes are provided with electrical connectors at opposite axial ends to enable electrical connection with adjacent tubes in adjacent tile assemblies.||05-14-2009|
|20090098775||Electrical Connection System - An electrical connection system for providing electrical connection between first and second devices comprises one or more electrical connection posts and one or more electrical connection tubes. Each post has a first end and an opposite second end, where the first end is configured to electrically connect with a first device such as a photovoltaic cell. Each tube has an opening to receive and provide electrical connection with the second end of a respective post. First and second end connectors are provided at respective opposite axial ends of a connection tube to enable end to end electrical connection between adjacent tubes. The opening comprises a longitudinal slot together with a plurality of secondary slots. Each secondary slot comprises a first length that extends in a circumferential direction, and a second length that extends in the axial direction, with a circular portion that acts as an electrical contact. In order to connect the posts to a tube the tube is orientated so that the ends of the posts are in alignment with the slot. The tube is then slid axially so that the ends of the post are located within the slot and inside the tube adjacent respective first lengths of a slot. The tube is then rotated about its longitudinal axis and then slid axially so as to finally locate the ends within the circular portions.||04-16-2009|
|20090097961||Hydroelectric System - A hydroelectric system converts kinetic energy from water flowing off a roof of a building into electrical energy. The system comprises a turbine having a rotor and a generator disposed in a down pipe. The down pipe has an upper end that receives water running off the roof via gutters. The down pipe comprises first and second channels that extend from the upper end to respective outlets. Each of the outlets direct water onto the rotor causing rotation in the same direction. The channels are configured in a manner so that water entering the down pipe initially flows through the first channel and out from a first outlet. However in a heavy downpour the first channel may overflow into the second channel to subsequently flow out of a second outlet providing further drive to the rotor. A regulating reservoir is provided at the upper end of the down pipe to provide a controlled steady flow of water through the first channel. The reservoir has an upright wall provided with a lower outlet and an upper outlet. When water collects in the reservoir at a level below the outlet it flows into the first channel via the first outlet. If rain water volume within the reservoir increases sufficiently water will eventually flow through the second outlet into the first channel providing additional pressure to drive the turbine. Should the water level in the reservoir increase at a sufficiently greater rate than it flows out from the outlets it may then overflow the wall to flow down the second channel.||04-16-2009|
|20090096218||Wind Energy Conversion System - A wind energy conversion system for a building comprises one or more wind powered turbines, a pitched roof structure having a first pitch on which the turbines are mounted, and a cover supported on the pitched roof structure above the turbines. The cover has a second pitch that is less than the first pitch. The cover and roof structure together create a wind tunnel that directs wind to flow through the turbines. Cowlings are also provided for each of the turbines. Each cowling surrounds an upper portion of a corresponding turbine. The cowlings are aerodynamically shaped and configured to concentrate air flow across or through a wind rotor of its respective turbine. The cowlings extend in a vertical direction between the cover and the roof structure.||04-16-2009|
|20090095339||Roof Based Energy Conversion System - A roof based energy conversion system for a building with a roof comprises a roof frame structure and a plurality of solar energy converting tile assemblies. The solar energy converting tile assemblies may comprise a selection of photovoltaic tile assemblies that convert solar energy into electrical energy and thermal tile assemblies that convert solar energy to thermal energy. Both tile assemblies have substantially the same exterior appearance so as to be visually indistinguishable when laid together on the same roof structure. The energy conversion system may also incorporate a hydroelectric system that is configured to convert kinetic energy from rain running off the roof structure to electrical energy and a wind energy conversion system that converts kinetic energy of moving air into electrical energy. An energy management system may be provided that receives electrical energy from the tiles, the hydroelectric system, and the wind energy conversion system. The management system incorporates batteries and includes a connection system to enable energy produced by the system to be transferred to a supply grid.||04-16-2009|
