Question: What type of transmission does Tower to the People and Wardenclyffe Tower have in common?

Context paragraphs:
Power tower (power take-off): A power tower is a type of mechanical power take-off (or pto) which resides on an auxiliary transmission.  It is mounted to the top of an auxiliary transmission (also known as a brownie or joey box) and its vertical housing has earned it the name power tower.  Unlike traditional transmission or engine mounted power take-offs the power tower can provide the engine's full rated power output.  It is commonly used to drive large winches or hydraulic pumps.  Unlike the power take-off of an agricultural tractor, the attachment of any device to the power tower is usually permanent.

Over the Air Rekeying: Over the Air Rekeying (OTAR) is the common name for transmitting, or remotely transferring, changing or updating data signal encryption "code" keys in secure information systems by conveying the keys via encrypted electronic communication channels (“over the air”).  It is also referred to as Over-the-Air Transfer (OTAT), or Over-the-Air-Distribution (OTAD) depending on the specific type, use, and transmission means of the key being changed.  Although the acronym refers specifically to radio transmission means, the technology is also employed via land line and cable.

Petřín Lookout Tower: The Petřín Lookout Tower (Czech: "Petřínská rozhledna") is a 63.5-metre-tall steel-framework tower in Prague, which strongly resembles the Eiffel Tower.  The Petřínská rozhledna was built in 1891 and was used as an observation tower as well as a transmission tower.  Today the Petřínská rozhledna is a major tourist attraction.  The hill is roughly a half-hour walk up paths (which gets quite slippery in the snow) and the tower is a shorter but fairly tiring climb; however, the hill is served by a frequent funicular and the tower has an elevator for disabled people.  In 2014 the tower was visited by more than 557,000 visitors, with foreigners accounting for over 70% of said visitors.

List of castles in Greater Manchester: There are nine castles in Greater Manchester, a metropolitan county in North West England.  They consist of four motte-and-baileys, three fortified manor houses, an enclosure castle, and a possible shell keep.  A motte-and-bailey castle has two elements, the motte is an artificial conical mound with a wooden stockade and stronghold on top, usually a stone keep or tower.  A bailey is a defended enclosure below the motte, surrounded by a ditch.  Motte-and-bailey castles were the most common type of castle in England following the Norman Conquest.  A shell keep was a motte with a stone wall rather than a wooden stockade on top; there would have been no tower within the walls.  Four of Greater Manchester's castles are Scheduled Ancient Monuments: Buckton, Bury, Radcliffe Tower, and Watch Hill.  A Scheduled Ancient Monument is a "nationally important" archaeological site or historic building, given protection against unauthorised change.

Transstadial transmission: Transstadial transmission occurs when a pathogen remains with the vector from one life stage ("stadium") to the next.  For example, the bacteria "Borrelia burgdorferi", the causative agent for Lyme disease, infects the tick vector as a larva, and the infection is maintained when it molts to a nymph and later develops as an adult.  This type of transmission is seen in other parasites like viruses or "Rickettsia".  In addition to ticks, mites are another common vector.  Some sources consider transstadial transmission a type of horizontal transmission, whereas other sources consider it vertical or partial vertical transmission.

Wardenclyffe Tower: Wardenclyffe Tower (1901–1917), also known as the Tesla Tower, was an early wireless transmission station designed and built by Nikola Tesla in Shoreham, New York in 1901-1902.  Tesla intended to transmit messages, telephony and even facsimile images across the Atlantic to England and to ships at sea based on his theories of using the Earth to conduct the signals.  His decision to scale up the facility and add his ideas of wireless power transmission to better compete with Guglielmo Marconi's radio based telegraph system was met with the project's primary backer, financier J. P. Morgan, refusing to fund the changes.  Additional investment could not be found and the project was abandoned in 1906 and never became operational.

Tower to the People: Tower to the People - Tesla's Dream at Wardenclyffe Continues is a 2015 documentary film directed by Joseph Sikorski about Nikola Tesla's Wardenclyffe Tower.  The film documents the history and subsequent decline of the Wardenclyffe complex designed and built by Tesla in Shoreham, New York, as the main laboratory and facility for his experiments on wireless power transmission.  The documentary focuses on the role of J.P. Morgan, one of the main investors behind the project, who pulled his support after realizing free wireless energy would hurt his own business interests.  Tesla could not find additional investments and in 1906 the project was abandoned and never became operational.  After over a century of decay, the tower site was rescued by a successful fundraising campaign and will be converted into a museum – the Tesla Science Center at Wardenclyffe – honoring the legacy of the Serbian American inventor.

Uniparental inheritance: Uniparental inheritance is a non-mendelian form of inheritance that consists of the transmission of genotypes from one parental type to all progeny.  That is, all the genes in offspring will originate from only the mother or only the father.  This phenomenon is most commonly observed in eukaryotic organelles such as mitochondria and chloroplasts.  This is because such organelles contain their own DNA and are capable of independent mitotic replication that does not endure crossing over with the DNA from another parental type.  Although uniparental inheritance is the most common form of inheritance in organelles, there is increased evidence of diversity.  Some studies found doubly uniparental inheritance (DUI) and biparental transmission to exist in cells.  Evidence suggests that even when there is biparental inheritance, crossing-over doesn't always occur.  Furthermore, there is evidence that the form of organelle inheritance varied frequently over time.  Uniparental inheritance can be divided into multiple subtypes based on the pathway of inheritance.

Wardenclyffe Tower (album): Wardenclyffe Tower is the seventh studio album by guitarist Allan Holdsworth, released in 1992 through Restless Records (United States) and JMS–Cream Records (Europe), and in 1993 through Polydor Records (Japan); a remastered edition was reissued in 2007 through Eidolon Efformation, containing three bonus tracks (alternative versions of "Tokyo Dream" from 1983's "Road Games" and "The-Unmerry-Go-Round" from 1985's "Metal Fatigue") which were previously only available on the Japanese release.  The album's title is a reference to the real life Wardenclyffe Tower, or Tesla Tower, designed by inventor Nikola Tesla in 1901.  "Zarabeth" is named after a character in the "" episode "".

Block error: A block error is a common type of error in certain types of digital television transmission, particularly those that use image compression.  Its presence in a television image is a telltale sign that 1) the signal is broadcast digitally, as this type of error can not occur in analog transmission, and 2) that there is a significant amount of noise, as digital television is designed to tolerate a certain amount of interference.  Block errors are usually detected, but not corrected, by the receiving device and are commonly displayed as empty black boxes in the television image.
