[edit] Criticism
This is a great concept, but is there any criticism that can be addressed to make this article seem a bit more relevant?
I wonder if there are any current projects being done by students at Columbia which would address this.
I think this is an exciting concept and I would like to see this article grow to reflect its current progress. --Joseph.r.martinez 05:31, 20 June 2007 (UTC)
- I think the only downside is the cost. Grundle2600 01:12, 21 June 2007 (UTC)
There is certainly plenty to criticize, but nothing that I can find outside references for. But I'll soapbox here: first, there is no need for vertical farms. Even if 80% of Earth's arable land is in cultivation, it's not in very efficient cultivation. If the world average for crop efficiencies were brought up to the US or EU standards, production would at least double without a single additional hectare. Second, the concept as stated violates the first law of thermodynamics. Clearly, there is not enough solar energy hitting a tiny little building to feed 50,000 people, so a massive input of electricity would be needed for grow lights. The proposal is to get this from fermenting biomass, biomass produced with the energy of the grow lights! It's a perpetual motion machine.
Frankly, I have no idea how a Columbia professor can get away with this kind of nonsense. Chuao 22:14, 25 June 2007 (UTC)
Curious to know if GMO have been deemed required by the people behind vertical farming. If so, the intellectual property would increase the costs. jlam 21:30, 17 August 2007 (UTC)
[edit] Other companies making farmscrapers
Other companies that make or -have proposed- farmscrapers have not been described: See Michael Braungart's MBDC, Rafael Pizarro and finally Ken Yeang

[edit] removing of vegas claim
the ip reverted with comment - "24.126.76.179 (Talk) (4,468 bytes) (Removed Las vegas claim - refuted here:http://www.enn.com/ecosystems/article/28654" -
yet, http://www.enn.com/ecosystems/article/28654 does not seem to refute that:
"The city of Las Vegas, Nevada in the United States will build the world's first 30 story vertical farm. Scheduled to be open in 2010, the $200 million dollar project would produce food for 72,000 people."
please clarify this if you feel strongly that it does. Thanks. --Emesee (talk) 21:00, 16 March 2008 (UTC)
I've removed this claim again. See http://blog.businessgreen.com/2008/01/so-is-las-vegas.html for justification. There's no source to be consulted - no contractor, no architectural firm, no city planner, no nothing - and all potential sources have been negative. 24.174.69.211 (talk) 03:19, 24 March 2008 (UTC)
