While this company's idea is interesting, it is still two years away from even being approved for commercial use. There are at least two competitors with easier, simpler to use technology:

The problem, so many shipping containers just pilling up unused in the Western world, and forcing the creation of countless new containers in Asia, is certainly worth solving. But so many companies have tried and failed before. For my money, the Indian or Dutch version seems that more likely to win out. India has far lower steel costs, and is at the centre of shipping between Asia, Europe, Africa and Australia.
When bad men combine, the good must associate; else they will fall one by one, an unpitied sacrifice in a contemptible struggle. - Edmund Burke
