Though I would expect that from "militiaman21" ;-)
However, the local food movement needs to talk more about yield. It doesn't appear that humanity can sustain itself this way - small communities perhaps, but it's a first world luxury.
Also, "food miles" is a BS metric, the biggest energy sink is fertilizer (by far!). Ammonium Nitrate is made by fossil fuel + air - you are mostly eating energy from natural gas, not the sun, it would seem.
Don't the fancy arduino hydroponic setups have pretty exciting yield?
Admittedly, it's too expensive to set up to be used commercially for anything except... well, high-margin cash crops, let us say. But those costs should go down.
