Wind Powered Container shipping

I have lately been very interesting in combining archaic technologies with new ones, this story is about the return of tall sailing ships to the oceans as a commercial shipping alternative. Originally developed as a "green" way to transport, these sailing ships have become commercially viable with the high price of diesel. The company is shipping wine now, and the cost is only 5% more than standard shipping. When their new high-tech sailboats are constructed, they believe it will be less expensive.

Another interesting story is about the amateur builder of some of the best early submarines in Barcelona. Narcís Monturiol i Estarrol wooden submarine built these as a utopian vision of providing a safer way to dive for coral. Many of his innovations were not replicated until the modern era of nuclear submarines, such as an engine whose by-product is oxygen.
