Heat engines and heat pumps for the future |

Welcome to the web site for
Sunoba Pty Ltd. This business was formed to
commercialise a new heat engine and heat pump, known respectively as BEE (Barton Evaporation
Engine) and BDE (Barton Drying Engine). 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. Heat pumps use work to increase
the temperature of a heat reservoir.
Common examples are refrigerators and reverse-cycle air conditioners. The BEE and BDE are based
respectively on evaporation and condensation of water in an air-vapour
mixture at reduced pressure. These
devices were invented by the founder of the company. An experimental BEE was built
and tested successfully in mid 2008 (see photograph at right). Current priorities are to
identify industrial collaborators so that R&D can be continued, with the
goal of building a prototype BEE. |
