  • Publication number: 20170002731
    Abstract: Human used to get power from gas expansion in heat engine. Extraction of mechanic work from gaseous expansion is always low efficient, because circa 70% energy is hidden in the exhausted vapor in the form of latent heat and rejected or dumped out of cycle because the slow condensation may choke mass conservative looping. As liquid is hard to be compressed, power transmission can be reasonably assumed lossless, so harvesting mechanic power from liquid flow is high efficient. But historically it is rarely considered for how to form a powerful liquid flow in a typical gas-liquid dual-phase co-existed thermodynamic system, such as the most used Rankine-cycle heat engine. A new method or say Wei heat engine is invented that is based on a new defined Wei second class thermodynamic cycle.

  • Publication number: 20160160477
    Abstract: Atmosphere contains huge vapor latent energy. This set of inventions discloses a method to scavenge the said latent heat and distribute it to heat demanding space, or for power generation. The condensed water can be collected for living, such that makes special sense for desert or marine zone. It is well known that a cup of hot coffee sitting on glass table can produce water droplets underneath bottom cavity. This invention is mimicking the said hot coffee phenomenon. Different embodied apparatuses are depicted: one is totally a free energy version with special hydrophobic IR reflection coating design, the other one needs minor energy to wipe away the condensed water in a pulse mode. All embodiments must have a starting process to warm up working fluid in a partially insulated container by whatever heater. Although the description is lengthy, it is worthy to seriously study the full contents for the spirits of revolutionary exploitation of free energy.

  • Publication number: 20150276232
    Abstract: Large size livestock animal, such as cow and horse, emits significant heat energy all time. A special device of water jacket works both as animal clothes and thermal collector. There are 3 hoses attached to the water jacket: 2 for water circulation; 1 for skin vapor collection. Animals are penned on an open camp or uninsulated tie-stall barn. All hoses are hooked to a pipe matrix that is systematically connected to a barn-side water tank and vapor compressor. Another building-side water tank is used to store higher temperature water that is the direct heat source of a radiant floor heating system. The heat pump draws heat from barn-side warm water tank, and discharges heat to building-side water tank, then supports radiant floor heating system in winter or heat engine power plant in summer. Water jack can also relieve the animal heat stress, because underground water is cooler than ambient air during hot season.
