Megaworld Hawaii exposes the amazing technology and science of one of the world's most popular vacation destinations. We catch up with Japanese extreme-sailor Kenichi Horie as he attempts a Guinness world record trip from Hawaii to Japan aboard the world's most advanced wave-powered boat. Then we burn our feet mapping flowing lava from the world's most active volcano in the accompaniment of Jim K Hawaii's foremost expert on volcanoes. We watch the world's most powerful underwater vacuum Hawaii's "Super Sucker" as it sucks alien algae off the ocean floor and then travel even deeper underwater in a high-tech manned submersible. And that's just a start from sand to surf we'll expose Hawaii like you've never seen it before.
