Some people come to America by shipping container:
When 29 undocumented Chinese nationals were found trying to enter the United States through the Port of Los Angeles in April, it wasn’t the Border Patrol that caught them. The men had arrived in a cargo container carried on a Panamanian vessel that had last stopped in China and Hong Kong. L.A. port security personnel spotted them wandering around a cargo area.
The security officers called the U.S. Coast Guard and Immigration and Customs Enforcement, who later described the scene as familiar: a 40-foot shipping container filled with empty food packages, water bottles and receptacles overflowing with human waste.
Smuggling fees for migrants from China can run as much as $60,000 per person. While tougher security in the post-9/11 world has decreased the smuggling of immigrants by sea, the practice continues.
"It isn’t all that uncommon," said Tony Migliorini, a spokesman with the Coast Guard. "We have caught them several times."
It seems to me that the worst part of this, by far, would be human waste. Food wouldn't be that much of an issue. You could eat raisins, chips, and other portable non-perishables for a month. I don't see why you couldn't even put a small microwave in there, powered by a generator, although I think a fridge would take too much energy. If you had a generator, you could have a lamp, and maybe power up a Kindle e-reader or an iPad. It might even be kind of fun. Get away from it all for a while, read, watch movies. But the human waste would make it horrible-- unless a chemical toilet would fix the problem.
A chemical toilet is a toilet which uses chemicals to deodorize the waste instead of simply storing it in a hole, or piping it away to a sewage treatment plant. Common types include aircraft lavatory, some passenger train toilets and the portable toilets used on construction sites and at large gatherings. They can normally be identified with a blue-colored dye in the bowl water. In the Americas and Europe this blue liquid formula is generally called "Anotec" filled with black chemical liquid. An even simpler chemical toilet consists of a seat on a container or bucket of water, with a solution of chemicals used to disinfect and/or deodorize. These are sometimes found on inter-city buses or in homes where indoor plumbing is not available. Portable toilets are universally chemical toilets.
Since formaldehyde is very irritating to the eyes, ears, skin, nose, and throat, it is being replaced by other proprietary blends such as glutaraldehyde and quaternary ammonium compounds, with non-staining dyes and nature-identical perfume oils. Additionally, enzyme hybrids are sometimes used.
Are there any chemical toilets effective enough now to keep a shipping container with a human inside reasonably pleasant for a month? If not, is that something that might be invented soon, I wonder?
