Current U.S. immigration and work visa rules can be so challenging that foreign students, workers and entrepreneurs have to head to other countries to fulfill their high-tech dreams. Now, a California startup is proposing to stem the tide of the brain drain by docking a residence vessel in international waters 12 miles off the coast of San Francisco.

For a country with over 9,000 miles of coastline, it's kind of surprising that China is just now welcoming its first aircraft carrier into its maritime defense fleet. The new addition has some of its neighbors nervous, though China is assuring the world it comes in peace.

If you're a billionaire who's tired of the constant competition to own the world's largest yacht, you might want to consider bidding on this British aircraft carrier so you can blow your fellow billionaire's weeny little boats into the weeds.
