Vertical Farming

March 17, 2010 • Daily Email Recap

In response the article I distributed last week on vertical farming, one agronomist commented:

It’s a completely crackpot idea promoted by innumerate people who have no idea about growing plants… When I did delve into it last year, they were underestimating the lighting requirement by a factor of about 50, and not allowing for the energy conversion to light, or the energy consumed by any of the other functions of the building, let alone the cost and resource consumption in its construction. No idea how they expect to keep CO2 coming in and oxygen going out, without losing any water vapour. It doesn’t add up any way you look at it.
