When the billions start piling up, what's a mogul to do?
Sure you could buy a $49 million Aspen mansion with its own sewage treatment plant. But why stop there? We started making a list of the bizarre things millionaires do with their money when we spotted this story on folks dropping millions to buy luxurious doomsday-safe condos built in a Cold War-era missile shaft.
There are also deals on bulletproof gear and, of course, insanely expensive jets to buy. Below, a round-up of some of the quirkiest things that ultra wealthy people have done with their money:
Build Emergency Rooms In Homes
Some <a href="http://www.huffingtonpost.com/2012/03/16/concierge-medicine_n_1353155.html" target="_hplink">super-rich households bypass</a> the long waiting room lines at hospitals by constructing emergency rooms -- costing over $1 million -- in their own homes.
Buy Submarine To Visit Ocean's Deepest Part
No place is off-limits to the super-rich. <a href="http://www.huffingtonpost.com/2012/03/19/submarines-super-rich_n_1365014.html" target="_hplink">Billionaire film director James Cameron bought</a> a single-person submarine to venture seven miles below sea level to the deepest part in the ocean.
Receive Psychological Wealth Counseling
Some <a href="http://www.huffingtonpost.com/2012/04/11/wealth-counseling-banks-super-rich_n_1417351.html" target="_hplink">super-rich bank clients pay for therapists</a> to help them deal with the psychological issues associated with having lots of money.
Get Doomsday-Safe Underground Luxury Condo
Super-rich buyers plan to survive the world's end in luxury condos<a href="http://www.huffingtonpost.com/2012/04/11/super-rich-doomsday-shelter_n_1417895.html" target="_hplink"> built in a Cold War-era missile</a> shaft below a Kansas prairie.
Purchase Ballistic Shield Briefcases
The super-rich spend on ways to <a href="http://www.huffingtonpost.com/2012/05/30/super-rich-protection_n_1556322.html" target="_hplink">protect themselves and their stuff. China's Leison Global </a>made a briefcase that turns into a ballistic shield. It's meant to safeguard rich businessmen and women.
Install ATM Machine In Kitchen
The super-rich enjoy having money at their finger tips. NBA star DeShawn Stevenson didn't like the idea of having to find an <a href="http://www.huffingtonpost.com/2012/05/31/deshawn-stevenson-atm-in-kitchen_n_1558565.html?ref=money" target="_hplink">ATM machine to withdraw cash</a>, so he put one in his kitchen.
Buy Humongous Private Planes
Rich people seem to hate lines, including the long security ques at airports. Like many wealthy people who have their own private jet, <a href="http://www.huffingtonpost.com/2012/06/06/alisher-usmanov-russian-facebook-airbus-a340_n_1574425.html?1339002993" target="_hplink">Russian billionaire Alisher Usmanov also bought</a> one. But his is an AirBus A340, the largest one in Russia and quite possibly the whole of Europe.
Throw Paper Planes Made Out Of Money
The super-rich can throw away money -- quite literally. Pavel Durov, the millionaire owner of the popular Russian social networking site VKontakte, <a href="http://www.huffingtonpost.com/2012/05/30/pavel-durov-russian-millionaire-throws-money-paper-planes_n_1557404.html" target="_hplink">tossed 5,000 ruble notes folded</a> into paper planes out of his office window onto a crowd in St. Petersburg.
