A hydrodynamic electrification system that generates electricity from water moving from a high side to a low side and around a structure that divides the low side from the high side generally includes a water transport system that directs the water from the high side presenting a hydraulic head, over the structure, and to the low side. The system includes a power extraction system having a wheel that receives the water from said water transport system and a mounting system having a high side anchor that connects near an intake to the water transport system at the high side and having a low side anchor that connects to the power extraction system at the low side.

A safety system for a fish-tank siphon is an apparatus used to prevent suction of a fish-tank-cleaning siphon from becoming obstructed by fish, underwater plant life, rocks, or other large tank contaminants. The apparatus is configured to protect the intake by preventing potential obstructions from entering the siphon at all. The apparatus includes a grate, a mating mechanism, and a siphon inlet. The grate acts as a protective filter, preventing large items from entering a connected fish-tank-cleaning siphon. The mating mechanism allows for connection of the present invention to a fish-tank-cleaning siphon. The siphon inlet is a section of the fish-tank-cleaning siphon through which the vacuum is applied in order to remove dirty water and water contaminants. The general configuration of these components allows the apparatus to prevent a fish-tank-cleaning siphon from incidentally collecting fish or other underwater creatures, plant life, pebbles, or other contaminants while vacuum-cleaning a fish tank.

A multiple stage discharge system for a gravity-fed emergency shower system is provided herein. The multiple stage discharge system includes a drain; a first opening defined by the drain; a second opening defined by the drain; and a valve mechanism coupled to the second opening to permit fluid in a fluid tank of the gravity-fed emergency shower system to flow at least partly through the drain via the second opening in response to a fluid level in the fluid tank decreasing to at or below a threshold fluid level.

A simple pneumatic ejector pump system allows for efficient transfer of a fluid such as water and has an air release port check valve assembly that opens as the chamber of the X-Pump empties so that it rapidly fills with water again. The air release port check valve assembly works with a check valve on a siphon tube to ensure that the pumping process occurs smoothly and at high efficiency.

A solar powered sediment capture system is disclosed for collecting sediment at environment sites such as lakes and rivers. A mechanical pump directs water from a containment basin to an upper tank and an antistatic pressure tank, both which are elevated. Gravity flow from the upper tank generates vacuum to establish a syphon for drawing a flowable sediment slurry from an environmental borrow site to a filter. Effluent from the filter passes down to the containment basin, which has water level at a lower elevation than that of the borrow site. Anti-static and driller conduits permit gravity flow from the anti-static tank to suspend the sediment and to maintain the slurry at the syphon inlet in a flowable state.
