Walter De Haas
Walter de Haas (1886–1969), who wrote under the pseudonym Hanns Günther, was a prolific German author, translator, and editor of popular science books. He began to publish books in 1912, including introductions to topics in electrical engineering under the '' Franckh'schen Verlagshandlung'' imprint and popular science works in the same publisher's ''Kosmos series''. His books remain exemplary for their combination of exactness and ease of understanding. Today, his most important book is considered to be "In a hundred years: the world's future energy supply" (''In hundert Jahren - Die künftige Energieversorgung der Welt''), which was published in 1931 for Franckh's "Friends of Nature Club" (''Gesellschaft der Naturfreunde''). In the book, he started by pointing out that humanity would one day run out of coal (he dismissed petroleum as a source of energy because he felt that it would run out very quickly) and went on to discuss other possible sources of energy that could replace c ...

Kosmos (publisher)
Franckh-Kosmos Verlags-GmbH & Co. is a media publishing house based in Stuttgart, Germany, founded in 1822 by Johann Friedrich Franckh. In the nineteenth century the company published the fairy tales of Wilhelm Hauff as well as works by Wilhelm Waiblinger and Eduard Mörike. The "Friends of Nature Club" () was set up in 1903 in response to booming public interest in science and technology, and by 1912 100,000 members were receiving its monthly magazine "Cosmos" (''Kosmos''). The company moved into publishing books on popular science topics under the brands ''Franckh’sche Verlagshandlung'' and ''KOSMOS'', including successful non-fiction guidebooks by Hanns Günther and Heinz Richter. Children's fiction and Kosmos-branded science experimentation kits were introduced in the 1920s. Kosmos's current output includes non-fiction, children's books, science kits and German-style board games. Many of their games are translated into English and published by Thames & Kosmos.

Geothermal Power
Geothermal power is electrical power generated from geothermal energy. Technologies in use include dry steam power stations, flash steam power stations and binary cycle power stations. Geothermal electricity generation is currently used in 26 countries,Geothermal Energy AssociationGeothermal Energy: International Market Update May 2010, p. 4-6. while geothermal heating is in use in 70 countries. As of 2019, worldwide geothermal power capacity amounts to 15.4 gigawatts (GW), of which 23.9 percent or 3.68 GW are installed in the United States. International markets grew at an average annual rate of 5 percent over the three years to 2015, and global geothermal power capacity is expected to reach 14.5–17.6 GW by 2020. Based on current geologic knowledge and technology the Geothermal Energy Association (GEA) publicly discloses, the GEA estimates that only 6.9 percent of total global potential has been tapped so far, while the IPCC reported geothermal power potential to be i ...

Solar Updraft Tower
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. As of mid 2018, although several prototype models have been built, no full-scale practical units are in operation. Scaled-up versions of demonstration models are planned to generate significant power. They may also allow development of other applications, such as to agriculture or horticulture, to water extraction or distillation, or to improvement of urban air pollution. Commercial investment may have been discouraged by the high initial cost of building a very large novel structure, the large ...

Wave Farm
Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC). Waves are generated by wind passing over the sea's surface. As long as the waves propagate slower than the wind speed just above, energy is transferred from the wind to the waves. Air pressure differences between the windward and leeward sides of a wave crest and surface friction from the wind cause shear stress and wave growth. Wave power is distinct from tidal power, which captures the energy of the current caused by the gravitational pull of the Sun and Moon. Other forces can create currents, including breaking waves, wind, the Coriolis effect, cabbeling, and temperature and salinity differences. As of 2022, wave power is not widely employed for commercial applications, after a long series of trial projects. Attempts to use this energy began in 1890 or earlier ...

Tidal Power
Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods. Although not yet widely used, tidal energy has the potential for future electricity generation. Tides are more predictable than the wind and the sun. Among sources of renewable energy, tidal energy has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability. However, many recent technological developments and improvements, both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (e.g. new axial turbines, cross flow turbines), indicate that the total availability of tidal power may be much higher than previously assumed and that economic and environmental costs may be brought down to competitive levels. Historically, tide mills have been used both in Europe and on the Atlantic coast of N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinz Richter (engineer)
Heinz Richter (1 November 1909 – 14 May 1971) was a German radio engineer and one of the most successful authors of introductory-level radio and electronics textbooks in Germany from the 1950s throughout the 1970s. Biography Born in Gehrden, Germany, Richter was influenced early by the books of Walther de Haas (" Hanns Günther"). He enrolled in the ''Höhere Technische Lehranstalt'' in Munich, from which he graduated as Engineer in 1932. Already in 1934, in cooperation with Günther, Richter published his first textbook for radio engineers, ''Schule des Funktechnikers'', which immediately became popular. This was soon followed by a revised edition of Günther's classic, ''Elektrotechnik für Jungen'' (Electronics for Boys). In the 1930s and 1940s, Richter worked as a development engineer and engineering group leader at the radio research group of the Aeronautical Research Institute in Oberpfaffenhofen ''(Forschungsinstitut für Flugfunk)'' under Prof. Max Dieckmann (toda ...

Fritz Kahn
Fritz Kahn (29 September 1888 – 14 January 1968) was a German-Jewish physician who published popular science books and is known for his illustrations, which pioneered infographics. Biography Fritz Kahn was born in Halle an der Saale, Germany, the son of Arthur Kahn, a physician and author, and Hedwig Kahn, ''née'' Schmuhl. His father emigrated to the USA shortly after his birth, settling in Hoboken, New Jersey. Around 1893, after establishing his practise, he sent for his wife and son, and Fritz Kahn started school there. The family later moved to Manhattan, but in 1895 his mother returned to Germany with her three children. They spent time in Hamburg and again in Halle before moving to Bonn with Arthur Kahn after his return from the US, then finally in 1905 moved to Berlin, where Kahn took his Abitur at the ''Sophiengymnasium''; he also served as an instructor in classes for workers. Kahn studied medicine at the University of Berlin beginning in 1907, passing the state e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
