Use of Convergent Nozzle to Convert Enthalpy into Kinetic Energy and Solar Energy into Electricity in the Convective Energy Conversion Cycle
Summary
The author proposes a new cycle for the conversion of solar
energy into electricity using natural convection. The
convective energy conversion cycle uses sealed ground level
solar air collectors and could be developed for large scale
generation. In previous proposals on this website there has
been one crucial missing link. A convergent nozzle allows
efficient conversion of the enthalpy of warm air flow into
kinetic energy. Its addition immediately pre turbine to CECC
should allow conversion of solar energy into electricity
with good efficiency. The author asserts that all the
changes involved are subject only to the first law of
thermodynamics and could allow the conversion of solar
energy into electricity with an overall efficiency of over
50%.
