Guess that Mystery Machine—Now with a Prize!

Diesel generator

Do you know what this is? Tell me in the comments. I’ll update Monday morning with the correct answer—the first person to guess correctly gets a $20 iFixit gift certificate! Just make sure to include your email address so I know where to send it.

UPDATE: Thanks for all the great guesses! Many of you were correct. This is a diesel generator at a Delhi market—since power is so unreliable, each of the stalls has one just in case. Brandon was the first to guess correctly, less than ten minutes after the post went up; I’ve sent him a gift certificate code.
