Environmentally safe hydro-electric pipeline and water delivery system

Номер: US20120020734A1
Автор: James M. Ross
Принадлежит: Individual

“The Environmentally Safe Hydro-Electric Pipeline And Water Delivery System” will provide over one million gallons of fresh water per day to areas and communities in desperate need of clean fresh water. This will be accomplished with a very small environmental footprint. This pipeline will be self powered by use of gravity and siphon principals. There will be enough flow and water pressure left over to power many water turbine electric generators, which may be located anywhere along the pipeline, where the power can be sold.

Wireless Automation Systems and Methods for Controlling Fluid Pressure in a Building

Принадлежит: 9346678 Canada Inc

A wireless control system for fluids, such as water or gas, controls an electronic valve mechanism located at the main fluid entrance of buildings. The valve is kept closed when no request is made for use of the aquifer or gas system, thus lessening the pressure on the plumbing during the non-use of the system and greatly reduces risk of damage when a break occurs in plumbing. The valve can be controlled by sensors, which could be wirelessly and securely connected; by a central unit accessible via a screen placed directly on the unit; and through several types of interfaces available for better flexibility of the control system. A web interface can be accessed via a computer or mobile on the local network via Wi-Fi or from outside via VPN or web address and a specific port pointed to the previously configured network.
