Welcome to the web site for
Sunoba Pty Ltd. This web site contains details
of new heat engines that generate power through evaporative cooling of hot
air at reduced pressure. The principal
target applications are ·
booster
for open-cycle gas turbines ·
passive solar thermal power generation In simple terms, heat engines
turn heat energy into useful work.
They are used to generate electricity or provide mechanical power for
vehicles and equipment. Examples
include Otto or Diesel engines for vehicles, Brayton engines for jet
aeroplanes, and Rankine steam turbines to generate
electricity. The thermodynamic
cycle for the evaporation engine involves hot dry air +
water → power + cooled moist air This cycle was confirmed in an
experimental evaporation engine that was tested successfully in mid
2008. The evaporation engine can be
built in either continuous-flow or piston-in-cylinder form. A related technology is the condensation heat pump, which is
based on condensation of water vapour in air at reduced pressure and has the
opposite thermodynamic cycle to the evaporation engine. Please follow the links to find
out more. |
