This article has been in my photo album here at EcoModder for many years,but the image scale is so small it's been essentially useless.
Copy Pro separated out the two photographs and text as three separate scans to enlarge the image scale.
The article is from POPULAR SCIENCE,Feb. 1988,page 20.
If you've seen 'Airtabs' on big rigs,they are also created by Gary O.Wheeler.
PS The title should have 'generator',not what I typed originally.
