The methods and the apparatuses of an aeration equipment are described. The system includes a solar collector having a magnifying lens to direct and focus sun rays to a solar energy collector, a heat transfer unit, boiler, a water heater backup system, a condenser unit and steam engine, and plural electrical energy storage units to store and dispense electricity to the selected type of electricity user. At least one flange is connected to the main body, is oriented substantially perpendicular to the main body plane, and forms the first side of the triangle. The core clock generator stops the core clock during a frequency transition. A leak port communicated with outside air is provided in the valve body to communicate with between a seal point of the main-fluid annular seal member and a seal point of the fluorinated annular seal member. Each of a pair of pre-amplifiers receives a signal from a respective one of the first and second sensors.
