Welcome to the web site for Sunoba Pty Ltd.

 

This web site contains details of two concepts for solar thermal power generation.

 

BRRIMS[1]

 

BRRIMS, our current focus, denotes solar power generation that is

 

Brayton-cycle

Re-heated

Recuperated

Integrated

Modular

Storage-equipped

 

The goal is to produce dispatchable power through a new integration of Brayton-cycle engines, solar thermal heat collection and pebble bed thermal storage. The engines will be piston-cylinder, re-heated and recuperated. Utility-scale installations can be built up in modular fashion from a basic power unit anticipated to be approximately 100 kW.

EVAPORATION ENGINE[2]

 

Our previous focus was on the evaporation engine, a new concept to generate power through evaporative cooling of hot air at reduced pressure.

 

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-cylinder form.

 

A related technology is the condensation heat pump[2], which is based on condensation of water vapour in air at reduced pressure and has the opposite thermodynamic cycle to the evaporation engine.
