Example of a Solar Tower |
Solar Chimney |
Physical Principals involved | ||
flat plate air heater | ||
tall chimney | ||
vertical axis turbine | ||
pressure changes are converted into kinetic | ||
can be designed for 30-100 MW | ||
one attempt in Spain | ||
50 kW from 1986-89 | ||
200m tall and 45,000 m2 of collector |
Dish Sterling System |
Solar collector (paraboloidal dish reflector) | |
Sterling Engine | |
Mounted together and modular | |
gaseous H or He for coolant | |
10-15 kW range | |
interconnected to create 1 MW or more |
Selected Dish Sterling Sites |
Solar Pond |
Collects both Direct and diffuse components | ||
decreasing salt concentrations | ||
Higher at bottom / Lower at top | ||
organic Rankine-cycle engine and vapour generator | ||
90oC commonly found at bottom of pond |
