Humans have pretty much explored every corner of the earth - on land that is.
The most unexplored territories are in our deepest oceans, the bottom of which hard to reach due to human's silly need for oxygen.

We've managed, through technology and some stupidly brave souls, to conquer this with scuba gear and submersible vessels, but there are certain laws of nature that we just can't overcome.
Two such intrepid explorers however have recently patented their underwater 'tent' that will enable scuba explorers to stay further down under the sea for longer.
The inflatable Ocean Space Habitat was designed by National Geographic explorer Michael Lombardi and associate professor at New York University Winslow Burleson. They introduced the portable life-support system a few years back, but now that the concept is patented they are looking for divers interested to see what they can do with this 'tent', according to National Geographic.

The concept of underwater habitats for longer dives isn't new - oil rigs and science centres like the Aquarius have saturation-diving facilities that make it possible for long, deep dives.
These places, however, are fixed structures, whereas Lombardi and Burleson's 'tent' can be packed up and transported in luggage on flights with divers, is easily inflatable and can be set up anywhere underwater.
The habitat gives divers a chance to take off their equipment, have a snack, chat to their diving buddies, start processing their finds or even have a nap. Lombardi's aim with these tents is also to utilise the unproductive time wasted while waiting around at certain levels to decompress going up, and can help conserve tank air.
But he believes it's not only scientists and professionals that would find this 'tent' useful.
“Imagine if a tourist, normally limited to a one-hour dive, could stay under through that magical transition from sunlight to twilight to darkness—with all the life that emerges,” he tells National Geographic. “People could experience the ocean in a whole new way.”
You could even perhaps have some underwater tea parties while you're at it!
