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) means for allowing solar radiation to enter the enclosure,
- c) solar collection means located inside the enclosure, and
- d) a heat exchanger, located inside the enclosure and in thermal contact with the solar collection means.
A solar chimney, comprising:
- a) a generally cylindrical enclosure,
- b) an aperture formed in the enclosure for allowing solar radiation to enter the enclosure,
- c) a target substrate, located inside the enclosure, for absorbing solar radiation entering the enclosure,
- d) a heat exchanger, located inside the enclosure and in thermal contact with the target substrate.
A solar chimney, comprising:
- a) an enclosure defining a flow path for a fluid to be heated,
- b) an aperture in said enclosure for allowing solar energy from outside the enclosure to enter the enclosure,
- c) a target substrate, within the enclosure, for absorbing solar energy entering the enclosure, and
- d) means for distributing heat from the target substrate, across an interior region of the enclosure, so as to heat a fluid passing through the enclosure.
