A Passive Wetland Treatment System (PWTS) is an environmentally sustainable approach to treating contaminated water, particularly for mining and agricultural runoff. It utilizes natural wetland processes, such as sedimentation, filtration, and microbial activity, to remove pollutants like nutrients, heavy metals, and sediments without the need for mechanical intervention or external energy inputs. These systems rely on vegetation and natural hydrology to enhance water quality, making them cost-effective and low-maintenance solutions for water treatment.
There is no such thing as a "passive" solar system.

It's actually only considered a wetland, but the truth is the wetland was created man-made by a sewage system created in 1996. The only animals reecorded to live here are many types of birds. If you ask me that's just wrong.
A fail passive system is one in which a failure in the system results in the system becoming passive, meaning it will not actively intervene but will provide indications and alerts to the pilot. In aviation, fail passive systems are often used in autopilot and flight control systems to ensure continued safe operation in the event of a failure.
An active system has amplifiers and electronic crossover built in to the cabinet. A passive system has just the speakers and possibly a passive crossover (made up of capacitors and inductors) inside the cabinet. A passive system requires external amplifier(s) to work.

You can deactivate the passive antitheft system on your Ford focus by removing the antitheft system fuse. The location of the fuse can be found on the inside cover of the fuse box.
Sunlight is thermal energy. Passive solar system, passive solar design, passive solar window....you get the idea :-)
