Farm Aid - No not the concert

[kalos72]

So I was thinking bout raised beds being used in increasing possible food production and had a thought but I am not sure of the feasibility nor actual accuracy of the method.

What if a raised bed was given some sort of cold frame...and in the frame a pipe was run that was kept warm with steam fired water. Wouldnt that allow you to grow food longer into the winter, possibly all season long?

Perhaps it can even be a side effect of things like fuel production or food smoking or something to get more efficiency.

Perhaps they can even be raised in skyscrapers along the windows using the steam lines as a heat source?

Remember I am playing in Manhattan..
