Feed the people, shrink prison population, pay child support, give people jobs, heal the economy

There are abandoned buildings and vacant lots all over my city. Very useful space, under the right circumstances. http://www.youtube.com/watch?v=mCCN4nq7BlQ
2000 square foot buildings or rooftop installations, feed 65 people fruits vegetables and 8 oz. of fish every week forever. 20,000 would feed every person in Indiana, all of them can be build and stocked for less than $500 million.
Using monies meant to incarcerate non violent criminals, $55/day in Indiana, comes to just under minimum wage. The state could, technically, "hire" those perpetrators for that wage as a community service and incarceration program where they can still make a wage, but be able to pay the state in the same way they do for house arrest. Could also be used for child support payment by "volunteering" there.
