A wind vortex tower is enhanced by kinetic energy and heat of quasi-tangential and upward jets of saturated steam energizing, accelerating tornado-type flow and supporting stable electricity generation during the insufficient winds and calm. For action instead of absent wind at starts and operation over a long time, a staged system of flexible nozzles injects the steam jets into the zones of vortex channel. The system controls the tornado-type flow in the vorticity energizer, swirlers of sucked ambient air, condensate separators, re-enhancer of airflow and top diffuser. The steam is flashed from partially stored condensate heated nearly to 100° C. The condensate is partially delivered after centrifugal separation from saturated vortex core. The outside water heating system has one or two of compatible renewable, waste and secondary, or initial heat sources, and is intensified via sucking of heated water by vortex flow. A large-rating flow-through electric generator has an alternating magnetic whirl formed by magnetic concentrators whirled near vortex core and a three-phase stator with switched modules. The simplified towers are used for water and conditioned air production.

An aluminum-foam structural housing unit that is storm-proof, self-contained, and built to withstand natural disaster conditions resulting from hurricanes, tornadoes, earthquakes, and fire, and then assist its inhabitants immediately thereafter when interruptions in public utility system service can be experienced. The combined use of aluminum alloy and foam as its building materials gives the unit its great strength, as well as the versatility needed to face natural disaster conditions while providing absolute resistance to heavy winds, flooding, earthquake and fire. Since the unit is buoyant, during flooding conditions it lifts from the ground and is guided by vertical poles to maintain a horizontal orientation. The unit also automatically disconnects from public utility systems as lifting occurs, and it then provides its inhabitants with self-contained sources of water, electrical energy, and sewage management. Thus, the unit is designed to adjust to the flow of nature, instead of working against it.

Another variation of construction substantially uses parts commonly found in scrapped automobiles—permitting inexpensive windmills in villages in third-world countries where commercial electrical power is either too expensive or not available. Constant Velocity (CV) joints, wheels, alternators, power steering pumps, etc. can be salvaged, and a mill can be designed by a technician trained in that discipline.

A system of interconnected alarm modules for a building which warn of detectable hazards in and around the building as well as hazards such as natural disasters which originate elsewhere. The network includes at least one hazardous condition alarm module, capable of detecting dangerous conditions in and around the building such as carbon monoxide or smoke and which provides an audible warning accordingly and also transmits hazard-specific data through the network to all other alarm modules. For other types of hazard conditions, the network includes a radio receiver alarm module which receives broadcasts such as those from the National Oceanic and Atmospheric Administration that includes encoded data about hazards according to type of hazard and geographic location. When the radio receiver alarm module receives a broadcast which contains data indicating a threat for the geographic area to which it is preprogrammed, it provides an audible warning accordingly and also sends data, specific to the type of threat, to all other connected alarm modules. Each connected alarm module responds to data received from other interconnected alarm modules by generating audible alarm warnings specific to the type of threat. The radio receiver alarm module may be capable of receiver other types of radio or satellite broadcasts. Electric power to the network is preferably supplied by the building's power mains but may also be provided by a battery backup in the event of a power failure. This invention increases the usefulness of distributed hazardous condition detection systems, allowing them to warn about a great variety of dangers such as tornadoes, earthquakes and terrorism as well as the presence of smoke or other substances for which they were originally intended.
