It isn't unlimited or free unless you can extract it with a system
that has material, labor, and operational costs all equal to zero.

the labor is free

If you have free labor, have it flip burgers at McDonalds and buy
electricity from your local power company with the paycheck it gets.
You will get a LOT more energy from the same amount of labor.

Especially with the California minimum wage... $7.50/hr effective
1/1/07, $8.00/hr effective 1/1/08...
http://www.dir.ca.gov/Iwc/MinimumWageHistory.htm

Probably more in the San Francisco area.

For $8, what can you get... hmm... at $0.15/kw-hr, that's just over 53
kW-hr, or 192 Megajoules...

At $3.30/gallon gasoline, that's 2.4 gallons of gasoline...

And at 20 cents per pound, that's 40 pounds of potatoes. At 40 cents a
pound, that's 20 pounds of rice.
