25,000 gallons a year, per Acre...........

How many cars for 1 year, per Acre.........would depend on how you drive. 12,000 miles per year, @ 25 MPG, 480 Gallons per year = 1 Car....= 1 ACRE could power 52 Cars per year.

Someone know how man cars in the USA, we could see if we had enough land.........LOL

http://www.advisorperspectives.com/dshort/updates/DOT-Miles-Driven.php lists the total distance driven in the US is just short of 3 trillion miles. That would be 4.8 million acres at 25 mpg or a little less than a fifth of Ohio.

The process does not require land, it requires a surface exposed to sunlight, which could be warehouse rooftops, vacant lots in urban areas (not Detroit, it is too cold for this process to work much of the year), or even floating islands in the Gulf of Mexico.

Or maybe the Everglades, if it could be assured that the system would be highly unlikely to rupture and spill hydrocarbons all over the environment.

How about repurposing brownfields or hazardous waste sites?
