Abstract
A solar chimney includes a solar collector which heats air in the chimney, producing updrafts which can be harnessed to perform useful work. The solar collector may be located inside or outside the chimney. The device may include a reservoir for storing a heat transfer fluid, thus enabling the device to be used during both day and night. The solar chimney may be equipped with both internal and external solar collectors, operating in parallel. The solar chimney may also be equipped with multiple external solar collectors, connected in parallel to a reservoir. The solar chimney of the invention provides a convenient and practical way to convert solar energy into electrical power.

A solar chimney, comprising:
- a) an enclosure,
- b) a heat exchanger located within the enclosure,
- c) solar collection means located outside the enclosure, and
- d) means for conducting heat from the solar collection means to the heat exchanger.
A solar chimney, comprising:
- a) a generally cylindrical enclosure,
- b) a housing located outside the enclosure, the housing containing a target substrate for absorbing solar radiation entering the housing,
- c) a heat exchanger located inside the enclosure, and
- d) heat transfer means for conveying heat from the target substrate to the heat exchanger.
A solar chimney, comprising:
- a) an enclosure defining a flow path for a fluid to be heated,
- b) a solar collection means, located outside the enclosure, for collecting solar energy,
- c) means for transferring heat from the solar collection means to a heat exchanger mounted within the enclosure, wherein the heat exchanger is positioned to distribute heat across an interior region of the enclosure so as to heat a fluid passing through the enclosure.
