Here's a real phrase that seems unimaginably large.

250 billion.

Two Hundred Fifty Billion.

Dos Cientos Cinquenta Mil Millones.

Or as the Greeks would say, διακόσια πενήντα δισεκατομμύρια

After yesterday's post on saving 1.5 trillion calories in our food by 2015, I came across a story about four global companies in the food business. Between them, they sold

**250 billion**US dollars of products. In one year!

A shorthand description for the companies is ABCD.

**A**rcher Midland Daniels - $ 70 billion of grain, palm oil, ethanol**B**unge - $ 42 billion of soybeans, plant oils**C**argill - $ 116 billion of sugar, cocoa, corn, wheat, fertilizer, animal feeds- Louis
**D**reyfus - $ 20 billion of grain, cotton, orange juice, coffee, rice, sugar

Let's compare this

**250 billion**to other

**250 billion**numbers

1. Gross sales of food by 4 big companies

2. National debt of Mexico

3. Gross National Product of Denmark

4. 2500 metric tons of gold

5. Number of hours of television watched by all Americans last year

6. Forecast for online sales of products in the USA by 2014

7. The number of microflora bacteria in only 1 gram of probiotic supplements!

8. The following is the most math-ish example of 250 billion that I have found today:

Alan Chaumont and Tom Muller checked all the prime numbers up to 250 billion and found only 21 of them are Elite Prime numbers. They said,

"A prime number

**p**is called elite if only ﬁnitely many Fermat numbers

*F*= 2^(2

_{m}*) + 1 are quadratic residues of*

^{m}**p**. (huh?) Previously only the interval from 1 to 1 billion was systematically searched for elite primes and 16 such primes were found. We extended this research up to 250 billion and found ﬁve further elites, among which 1 151 139 841 is the smallest and 171 727 482 881 the largest."

Dennis Martin took their results and went on up a few hundred billions farther, but found no more elite primes.

I'm about to stop counting now. My final example?

9. The number of whirly-gig novelties created out of beer and soda cans for sale at flea markets!
