Abstract: Title: TAPERING SPIRAL GAS TURBINE WITH HOMOPOLAR DC GENERATOR FOR COMBINED COOLING, HEAT- ING, POWER, PRESSURE, WORK, AND WATER (57) : A tapering exponential spiral for a gas expander (503) for work extraction or air cooling is used. This tapering exponential spiral could also be used for a gas compressor (501) to increase the pressure and temperature of air. The compressor-expander forms a single and simple structure for easy manufac - turing. A simple formula for temperature drop across a tapering exponential spir- al for adiabatic expansion of air is derived. The pressure increasing as air is com- pressed outside in for isothermal compression of air is also derived. The spiral is proved efficient for energy conversion. The Faraday homopolar DC generator by changing its geometry and technology is improved. High work to electricity con- version efficiency and high voltage and power production are achieved. The same generator structure can be used as a homopolar DC motor. By controlling voltage, the speed of the motor or generator is controlled. By controlling current, the torque force used or produced is controlled. The homopolar generator and motor can be easily integrated with the spiral compressor and expander. Three applications using these basic inventions are proposed. First a heat turbine powered by concentrated solar energy or by burning gaseous fuel is proposed. Second, a heat pump powered by electricity for cooling, refrigeration, and heat- ing of water is proposed. Third, a method to desalinate water by solar power, us - ing concentrated sunlight to evaporate salty water under reduced pressure is pro- posed. The Firefly technology can provide small scale, local, and simple produc - tion of energy of many kinds, giving solar power back to the people where and when needed. axis W O 20 17 / 133 29 4 Al Fig.5 (12) INTERNATIONAL APPLICATION PUBLISHED UNDER THE PATENT COOPERATION TREATY (PCT) (19) World Intellectual Property Organization International Bureau (10) International Publication Number (43) International Publication Date WO 2017/133294 Al 10 August 2017 (10.08.2017) WIPO I PCT 1111111111111011011111111111010111110111111110111111111110111111111111110111111 (51) International Patent Classification: FOLD 1/32 (2006.01) (21) International Application Number: PCT/CN2016/105462 (22) International Filing Date: 11 November 2016 (11.11.2016) (25) Filing Language: English (26) Publication Language: English (30) Priority Data: 62/290,393 2 February 2016 (02.02.2016) US PCT/IB2016/001359 5 July 2016 (05.07.2016) IB (71) Applicant: MONARCH POWER TECHNOLOGY (HK) LTD.
