A water treatment system centrally communicates and controls one or more water treatment devices to regulate the use of the one or more water treatment devices. The water treatment system is configured to enable a localized, on-demand supply of purified water throughout a building or a network of buildings. The water treatment system may control a degree of purity (e.g., water hardness or concentration of dissolved salts) via mixing of purified and unpurified water streams in a controllable ratio (e.g., via one or more controllable valves or one or more tunable water softening units).

A fuel cell includes a flow field plate, a catalyst layer, and a gas diffusion layer (GDL). The flow field plate has at least one channel and at least one land. Each of the at least one channel being positioned between two adjacent lands. The GDL is positioned between the flow field plate and the catalyst layer. The catalyst layer has a first region aligned with the at least one channel and a second region aligned with the at least one land. The first region has a first composition, a first carbon material, and a first carbon ratio of an amount of the first composition to the first carbon material. The second region has a second composition, a second carbon material, and a second carbon ratio of an amount of the second composition to the second carbon material. The first carbon ratio is different than the second carbon ratio.

An implement for manually clearing snow, slush, or ice comprises an elongated handle and relatively narrow, shallowly curved blade and can permit a standing stationary operator to drive or otherwise draw the front face of the blade more or less face-on into fallen snow, slush, or ice to manually plow, propel, launch or otherwise move snow to a spot remote from the operator in a lateral direction outwardly away from the User, for example forward, sideways, or rearward. The implement can also be employed wherein the blade skims the pavement at a shallow angle permitting a rapid pushing motion to send a charge ballistically ahead of the blade to a distant spot and can also be employed in a traditional shoveling mode. The implement can clear open or narrow spaces, wide or narrow steps with or without parapet walls, rails, or other barriers, and it can be economically produced.
