What could I buy with a Trillion Dollars??

Trying to wrap my mind around what I could buy with a trillion dollars, I found some interesting figures showing what you could get with a trillion dollars. Some examples:

If you stack up $1,000 bills, $1 trillion would need a pile that is 80 miles high.

$ 1 trillion is more than the combined gross revenues of Wal Mart, Exxon, General Motors and Ford Motors.

Assuming the United States consumes about 17 billion barrels of oil a year and assuming the cost of a barrel of oil is about $65, a trillion dollars will buy an entire year's worth of oil for the USA.

You could buy a thousand Queen Mary 2 with accommodations for 2,620 passengers

With a population of approximately 300 million people, you could give away $1 trillion by giving every man, woman and child in the U.S. $ 3,400 each. Is this the debt that each American is going into now?

We could buy everyone on Earth an iPod. Whohoo!

We could pave the entire U.S. interstate highway system with 23.5-karat gold leaf.

We could buy 16.6 million Habitat for Humanity houses

We could hire 1.9 million additional teachers.
