| 20110077113 | Pass-through PTO mechanism for renewable engergy systems - A pass-through power take-off (PTO) mechanism for use with renewable energy systems is described to extract power from a linearly moving tether under high tension and to convert it to rotary power such as for driving an electric generator. Three such embodiments are described. The first uses two adjacent timing belts and transfers power from tether to PTO via friction. The second embodiment uses two adjacent roller chain loops and a mechanical engagement method to transfer power from tether to PTO. The third embodiment uses two adjacent double-sided timing belts and either a synchronous or an asynchronous method to transfer power from the tether to the PTO. | 03-31-2011 |
