How It Works
The WhisperGen
TM
onboard heat and power system is based on a four-
cylinder Stirling-cycle (external combustion) engine that repeatedly heats
and cools a mass of pressurised nitrogen gas. Each time the gas is heated
and cooled, the changing gas pressure causes the pistons to move up and
down. This mechanical motion, via a special mechanism called the "wobble
yoke", rotates an alternator to generate DC electricity which can be used to
charge a lead-acid battery bank.
The nitrogen gas is heated by a continuous-combustion burner, and cooled
by coolant circulating through engine cavities. Heat transferred to the
coolant can be used to heat domestic water cylinders and for space
heating.
The burner consumes air and fuel. The flow rate of air and fuel into the
burner is optimised by a microcomputer. This maximises combustion
efficiency and minimises exhaust emissions.
The microcomputer automatically controls all WhisperGen
TM
functions and
displays real-time information about the system on a control panel from
which the user can also alter operating options.
