An apparatus for controlling fluid flow, including a temperature sensitive material, having a first physical property at a first temperature and a second physical property at a second temperature, a device for controlling fluid flow, and a device for connecting the temperature sensitive material to the fluid flow control device. The connecting device may be configured so that the fluid flow control device is in a first position at the first temperature and in a second position at a second temperature. The temperature sensitive material may be aluminum wire or stainless steel wire. The temperature sensitive material may have the shape of an Archimedean spiral. The connecting device may be a motion amplifier. The first temperature may be a cryogenic temperature.

A rainwater collection assembly for collecting rainwater includes a reservoir that is mountable to a wall of a building and the reservoir has an inlet that is in fluid communication with a downspout of a gutter system of the building to direct rainwater into the reservoir for storage. The reservoir has a pair of outlets each being integrated therein to release the rainwater from the reservoir. A spigot is fluidly integrated into the reservoir to release the rainwater from the reservoir when the spigot is opened. An intake pipe is fluidly coupled to the inlet in the reservoir and the intake pipe can be fluidly coupled to a downspout of the gutter system for directing the rainwater into the reservoir.

A method and rainwater processing system are disclosed. According to one aspect, a method includes collecting rainwater, filtering the collected rainwater, and ozonating the filtered collected rainwater to produce potable water. The method includes diverting a portion of the collected rainwater to a test chamber and testing by sensors the diverted portion of the collected rainwater to produce a valve control signal. Responsive to the valve control signal, a valve is opened to channel collected rainwater to a collection tank and filtered. The method includes ozonating the filtered collected rainwater to produce potable water. A functional water may be prepared by adding a substance to the potable water within a processing tank. The functional water may be carbonate and ozonated.
