Thermodynamic energy methods and systems that provides all electrical energy and heat needs of a single residential house, commercial business or office building. The system is small enough to be stored inside the house or building. The system can generate excess electrical energy which can be sold over a power grid and allow for the house owner, building owner or energy provider (utility company) to provide income. The method and system can have combined energy conversion efficiency up to approximately 97%. Components can include amorphous materials, and the mono-tube steam generator boiler which is explosion proof when punctured, and only emits a puff of steam when punctured. The tubes can be built to pressure vessel code. The invention can use steam generators to power A / C units, domestic hot water, hot water air space heaters, other loads such as pools and spas and underground piping to eliminate ice and snow. Additionally, the invention can be used to power vehicles such as cars, and the like. Other embodiments can use thermodynamic energy methods and systems that provides electrical energy and heat needs of a residence, commercial business, or office building, that include supertropically expanding ammonia vapor against a vacuum, as generated by chemosorption, in order to convert moderate amounts of heat into mechanical energy at high efficiencies. A supertropic package system can include a source of ammonia / water, a thermal generator for heating the source of ammonia / water and generating ammonia gas, a positive displacement device for expanding the gas, and generating electricity from a power source driven by the expander.

The present invention relates to an improved antifreeze composition for use in engine cooling systems. The composition of the invention has sustained corrosion inhibiting properties even at relatively low concentrations and when used with hard water. The composition comprises an antifreeze agent, an organic acid, a poly(organic acid), dimercapto thiadiazole, a hard water stabilizer, a phosphate salt, a triazole or thiazole and alkali metal hydroxide.

The invention provides a plastic tube film winding production device which comprises a hollow rotary plate arranged on a rack. A plastic tube outputted in the same axial direction of a central axis of the rotary plate is arranged in a rotary plate through hole, a wide film strip winding drum and a packaging strip winding drum are arranged on the front side of the hollow rotary plate and both parallel to a central axis of the plastic tube, stretch rolls used for stretching a wide film strip and a packaging strip are arranged on the front side of the hollow rotary plate. By a mode of winding the plastic tube in the same direction, winding of a plastic tube film and the packaging strip on the plastic tube is realized, packaging is realized while discharging of the plastic tube, and labor cost is reduced greatly while working efficiency is improved.
