To someday allow scientists to stay underwater conducting research for days on end, the UK-based company DEEP has designed Vanguard, a "subsea human habitat."

The company unveiled its prototype Wednesday at a hangar in Miami, Florida, hoping that oceanographers and other researchers can use it to stay underwater in the ocean for at least a week, instead of only a few hours like most expeditions.
