[HH] Food hacking

[Stephen Ronan]

Interesting. I suppose the need for paths between rows of many crops
for tractor tires and/or farm workers reduces density for many crops
on farms relative to something like these shipping container farms
based in South Boston: https://www.freightfarms.com/
I found the short videos there worth watching. One claims as much
lettuce can be grown in a shipping container as on two acres of
land...

Apparently, the relatively low heat transfer from LED lights also
facilitates denser crops

In a preview snippet from this book "LED Lighting for Urban Agriculture"
http://www.springer.com/us/book/9789811018466
I see: "Luminous efficacy (lumen per watt) of white LED tips was 75 in
2010 is 50 in 2016 and will reach around 200 in 2020 (Fig 1.1). "
