A dynamo (from the Greek word dynamis; meaning power), originally another name for an electrical generator, generally means a generator that produces direct current with the use of a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a mechanical commutator. Also, converting alternating to direct current using power rectification devices (hollow state or more recently solid state) is effective and usually economic.

The word still has some regional usage as a replacement for the word generator. A small electrical generator built into the hub of a bicycle wheel to power lights is called a Hub dynamo, although these are invariably AC devices.^{[citation needed]}

Michael James Owen (born 14 December 1979 in Chester) is an English professional footballer who is currently a free agent after being released by Manchester United in June 2012.

The son of former footballer Terry Owen, Owen began his senior career at Liverpool in 1996. He progressed through the Liverpool youth team and scored on his debut in May 1997. In his first full season in the Premier League he finished as joint top scorer with 18 goals. He repeated this the following year and was Liverpool's top goal scorer from 1997–2004, despite a recurring hamstring injury. In 2001, Liverpool won a cup treble of the UEFA Cup, FA Cup and Football League Cup, and Owen was the recipient of the Ballon d'Or. He went on to score 118 goals in 216 appearances in the Premier League for Liverpool.

Owen moved to Real Madrid for £8 million in mid-2004; he was frequently used as a substitute. He scored 13 goals in La Liga and had the season's highest ratio of goals scored to number of minutes played. He returned to England the following season, joining Newcastle United for £16 million. After a promising start to the 2005–06 season, injuries largely ruled him out over the next 18 months. After his return he became team captain and was the team's top scorer for the 2007–08 season. After the final season of his four-year contract, Newcastle were relegated, and Owen moved to Manchester United as a free agent.

Wayne Mark Rooney (born 24 October 1985) is an English footballer who plays as a striker for Premier League club Manchester United and the England national team.

Rooney made his senior international debut in 2003 becoming the youngest player to represent England (a record later broken by Theo Walcott). He is England's youngest ever goalscorer. He played at UEFA Euro 2004 and scored four goals, briefly becoming the competition's youngest goalscorer. Rooney featured at the 2006 and 2010 World Cups and is widely regarded as his country's best player. He has won the England Player of the Year award twice, in 2008 and 2009. As of September 2011, he has won 73 international caps and scored 28 goals. Along with David Beckham, Rooney is the most red carded player for England, having been sent off twice.

Aged nine, Rooney joined the youth team of Everton, for whom he made his professional debut in 2002. He spent two seasons at the Merseyside club, before moving to Manchester United for £25.6 million in the 2004 summer transfer window. The same year, Rooney acquired the nickname "Wazza". Since then, with Rooney in the team, United have won the Premier League four times, the 2007–08 UEFA Champions League and two League Cups. He also holds two runner-up medals from both the Premier League and the Champions League. In April of the 2011–12 season Rooney scored his 180th goal, making him United's fourth highest goal-scorer of all time.
