LONG BEACH - A youth banjo band, a 14-year-old who built a nuclear fusion reactor in his garage and U2 singer Bono are among the innovators who will be in town this week for TED 2013.

The sold-out, invitation-only conference, TED - which stands for technology, entertainment, design - begins on Monday in downtown Long Beach for the fifth and final time before moving to Vancouver, Canada, next year.

The theme this year is "The Young. The Wise. The Undiscovered." TED used a global talent search at localized TED events to find hidden gems of innovation.

While the exclusive event may be off-limits to most, the videos that were used to choose from among almost 300 finalists are available at ted.com.

The website also includes videos of past years' speakers in Long Beach at other TED conferences around the world.

The non-profit devoted to "ideas worth spreading" was started in 1984 as a conference to bring together people from the technology, entertainment and design industries.

Two annual conferences in Long Beach and Palm Springs have been held each spring, and the TEDGlobal conference in Edinburgh, Scotland, is held each summer.

Speakers address subjects such as science, business, the arts and global issues. Over the four-day event in Long Beach, 50 speakers will each use an 18-minute slot to share their ideas and thoughts.

The prestigious conference has been lauded by city leaders for putting an international spotlight on Long Beach. The event is held at the Long Beach Convention and Entertainment Center, which closes off its fountain plaza facing Ocean Boulevard for the event.

TED officials announced early this month that the conference is moving to Vancouver, where one of the organization's two headquarters is located, next year.
