| 20120128496 | WIND ENERGY USE - The invention provides wind energy use. One application provides wind energy use for water harvesting from natural humid air. The method is based on changing thermodynamic state properties of ambient airborne wind passed through a convergent-divergent system. The device comprises a cascade of sequentially arranged wind converging and wing-like components. Those components transform the wind into fast, cooled, out-flowing air portions. The decrease in static pressure and temperature triggers condensation of water-vapor into water-aerosols. Another application of the method provides an effective mechanism for harvesting electrical energy from naturally warm air using renewable wind energy, including the wind inertia, internal heat, and potential energy stored in the air mass in the Earth's gravitational field. The electrical energy harvesting mechanism is also applicable to use of natural renewable energy of streaming water. | 05-24-2012 |

SINGLE BLADE ROTARY IMPELLER WITH COUNTERBALANCE | 1 |
| 20100278646 | Fan, especially a ceiling fan with a balanced single blade - Described is a fan with a blade suitable for use as a ceiling fan. The blade may be regarded as a single blade, although shaft is not attached to blade at one end thereof; rather, shaft is attached to blade at a point between first end and second end. Blade is balanced by counterweights located in blade. In one embodiment, blade is connected to shaft by means that permit angular movement, such as a teeter hinge. | 11-04-2010 |
