Green Vending Machines
These vending machines can actually grow vegetables without any sunlight, using 12 40W fluorescent lights housed inside. Apart from being able to actually sell it to you, The Chef’s Farm can produce almost 20.000 lettuce heads per year, the users being able to recoup their investment in no more than five years of using the machine 24/7.
The green vending machine goes on sale for ~90.000 $. Of course, this happens in Japan.
