The solar updraft tower (SUT) is a design concept for a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a hot air updraft in the tower by the chimney effect. This airflow drives wind turbines, placed in the chimney updraft or around the chimney base, to produce electricity.

The Dunn Solar Telescope is a unique vertical-axis solar telescope, in Sunspot, New Mexico located at Sacramento Peak, New Mexico. It is the main telescope at the Sunspot Solar Observatory, operated by New Mexico State University in partnership with the National Solar Observatory through funding by the National Science Foundation, the state of New Mexico and private funds from other partners. The Dunn Solar Telescope specializes in high-resolution imaging and spectroscopy to help astrophysicists worldwide obtain a better understanding of how the Sun affects the Earth. Completed in 1969, it was upgraded with high-order adaptive optics in 2004 and remains a highly versatile astrophysical observatory which serves as an important test platform for developing new instrumentation and technologies.
The Einstein Tower is an astrophysical observatory in the Albert Einstein Science Park in Potsdam, Germany built by architect Erich Mendelsohn. It was built on the summit of the Potsdam Telegraphenberg to house a solar telescope designed by the astronomer Erwin Finlay-Freundlich. The telescope supports experiments and observations to validate Albert Einstein's relativity theory. The building was first conceived around 1917, built from 1919 to 1921 after a fund-raising drive, and became operational in 1924. Although Einstein never worked there, he supported the construction and operation of the telescope. It is still a working solar observatory today as part of the Leibniz Institute for Astrophysics Potsdam. Light from the telescope is directed down through the shaft to the basement where the instruments and laboratory are located. There were more than half a dozen telescopes in the laboratory.
A solar telescope is a special purpose telescope used to observe the Sun. Solar telescopes usually detect light with wavelengths in, or not far outside, the visible spectrum. Obsolete names for Sun telescopes include heliograph and photoheliograph.

Long established are also the radio heliograph, a T-shaped array, and the decametric array operating at wavelengths between 3 m and 30 m.
The Astronomy Tower of the Sorbonne is a tower at the Sorbonne University's Paris campus built to house an astronomical observatory for its students. The structure was erected during the reconstruction of the Sorbonne, between 1885 and 1901. The tower is 39 meters high, has an upper and lower dome, and includes several rooms. The upper dome houses the telescope, and the lower dome contains an optics workshop for amateurs to make mirrors. The tower is operated by the Société astronomique de France and is available for tours and amateur observations.
The Observatory of the rue Serpente was an astronomical observatory owned and operated by the Société Astronomique de France in the historic Latin Quarter of Paris. It operated between 1890 until 1968, when it was transferred to a new location at the nearby Astronomy Tower of the Sorbonne.
Meudon Great Refractor is a double telescope with lenses, in Meudon, France. It is a twin refracting telescope built in 1891, with one visual and one photographic, on a single square-tube together on an equatorial mount, inside a dome. The Refractor was built for the Meudon Observatory, and is the largest double doublet refracting telescope in Europe, but about the same size as several telescopes in this period, when this style of telescope was popular. Other large telescopes of a similar type include the James Lick telescope (91.4), Potsdam Great Refractor (80+50 cm), and the Greenwich 28 inch refractor (71.1 cm).
Arago telescope is a 38 cm aperture refracting telescope at Paris Observatory, installed in 1857. Francois Arago ordered this telescope from the telescope making firm Lebreours in 1839, and after a protracted development was completed by 1855. The name Lunette Arago is a modern name for the telescope, and other large refractor of Paris observatory, is the one at Meudon. It has gone by a variety of names having to do with various aspects of the telescope, such as its aperture, or location on the East tower of the Paris observatory, or its equatorial mount made by Brunner. In one journal report it was called the 'east equatorial' for example, in another instance '38 cm refractor'. In French language it has been called the La lunette équatoriale de 38 cm de l'Observatoire de Paris.
