Power Rangers

Power Rangers is a long-running American entertainment and merchandising franchise built around a live action children's television series featuring teams of costumed heroes. Produced first by Saban Entertainment, later by BVS Entertainment, and as of 2015 by SCG Power Rangers, the television series takes much of its footage from the Japanese tokusatsu Super Sentai, produced by Toei Company. The first Power Rangers entry, Mighty Morphin Power Rangers, debuted on August 28, 1993 and helped launch the Fox Kids programming block of the 1990s, during which it catapulted into popular culture along with a line of action figures and other toys by Bandai.

Despite initial criticism for its action violence targeted to child audiences, the franchise has continued, and as of 2016 the show consists of 23 television seasons of 19 different themed series and two theatrical films, with a third film coming out in 2017. In 2010, Haim Saban, creator of the series, regained ownership of the franchise after seven years under The Walt Disney Company.

Space-based solar power

Space-based solar power (SBSP) is the concept of collecting solar power in space (using an "SPS", that is, a "solar-power satellite" or a "satellite power system") for use on Earth. It has been in research since the early 1970s.

SBSP would differ from current solar collection methods in that the means used to collect energy would reside on an orbiting satellite instead of on Earth's surface. Some projected benefits of such a system are a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere and night time in space.

Part of the solar energy (55–60%) is lost on its way through the atmosphere by the effects of reflection and absorption. Space-based solar power systems convert sunlight to microwaves outside the atmosphere, avoiding these losses, and the downtime (and cosine losses, for fixed flat-plate collectors) due to the Earth's rotation.

Besides the cost of implementing such a system, SBSP also introduces several new hurdles, primarily the problem of transmitting energy from orbit to Earth's surface for use. Since wires extending from Earth's surface to an orbiting satellite are neither practical nor feasible with current technology, SBSP designs generally include the use of some manner of wireless power transmission. The collecting satellite would convert solar energy into electrical energy on board, powering a microwave transmitter or laser emitter, and focus its beam toward a collector (rectenna) on Earth's surface. Radiation and micrometeoroid damage could also become concerns for SBSP.

Power Rangers in Space

Power Rangers in Space is an American television series and the sixth season of the Power Rangers franchise, based on the Super Sentai series Denji Sentai Megaranger.

As with all Power Rangers programs, in Space is based on one of the entries of the Super Sentai series. However, due to miscommunication between the United States and Japan as to the contents of the Sentai series, much of the space footage is original to the American adaptation. In Space was a turning point for the Power Rangers franchise, as the season brought closure to six seasons of plot, and it ended the practice of having regular cast members act in consecutive seasons. The theme of the series bears little similarity to its Sentai counterpart and its successor, Power Rangers Lost Galaxy.

Though its initial tone was similar to that of Mighty Morphin and Power Rangers Zeo, Power Rangers in Space eventually took a darker, more emotional turn.

Synopsis

Picking up where Power Rangers Turbo left off, Dark Specter has captured Zordon and is beginning to completely drain his powers. An assortment of old and new villains praises his victory, but an unexpected figure uncovers his plan: the Red Space Ranger, Andros. Dark Specter orders the new Princess of Evil, Astronema, to eliminate Andros so he can't jeopardize her plans.
