Decades ago, I was excited about the idea of this type of farming. However, as the years passed, and I found that the only way to get a tomato with a good flavor was to put a plant outside in a pile of dirt, I gave up on the idea.

At the supermarket, 12 months of the year I can buy perfect looking tomatoes that have absolutely no flavor. If they can't grow a good tomato, I sure don't want to try their meat products.

I think that this is the way to farm the future, if they can just come up with the technology, and it looks like they already have, and the start up costs, then this is the way to feed our constantly growing planet.

Of course there are ideas like this all the time, what with flying cars and giant skyscrapers containing hundreds of thousands of people and calling it a city. Well, its a good thing that we have PPX!

Future Tech is a wonderful thing, it lets thousands of people stand around, hands in pockets, watching video games and playing gladiator sports. We still present a picture of abundant energy to power all this technology, flying cars , robotic servants doing dirty work. The best thing is to keep as many people engaged and working as possible. Forget the robots, let people work. Idle people create to many problems.

We should find out which crops grow best here, which grow better in dirt. There can't be one solution fits all. I see smaller people powered vertical farms, not owned or managed by conglomerates, perhaps mom and pop shops. Maybe a more practical approach is a grid of connected smaller towns and villages growing different, varied crops, no mono-cultures

Or how do I turn my present garage on my small city lot, into a greenhouse, with an efficient food producing unit, that I can own and control and supplement my family's needs.

Top down approaches, corporate strategies, they are killing us. Sometimes being green does not require technology at all.

I think if this CAN REDUCE WASTED SPACE and power itself, than why not. In these days, no good idea should go unexplored.

I wonder if cereal crops can be grown this way.Will they hire conventional farmers to run these things? This system is ideally suited to desert areas that get plenty of sun,or Africa,where pests of various kinds can be kept out.

It looks like something that will turn out to be a million dollar subsistance farm. These things are fun to consider but with something like 60,000 people starving to death a day it's no answer to the problems of feeding the planet. Maybe feeding a small rich percentage of the U.S. but that's hardly a 'real life' solution, or even much of a consideration. Maybe stop trying to use food to fuel your cars would benefit more people than star trek subsistance farms.
