The energy impact of providing food to cities is often at most evidence in the transportation footprint. A company from Sweden is looking at a closer-to-home alternative.Physorg.com reports:
"Vertical greenhouses that grow organic fruit and vegetables smack in the middle of crowded cities where land is scarce may soon be a reality, a Swedish company developing the project said..
'A tomato seed is planted on the ground floor on a rotating spiral and when it arrives at the top, 30 days later, you pick the fruit,' the vice president of Plantagon, Hans Hassle, told AFP.
In a few decades, 80 percent of the global population will live in cities, increasing the need 'to grow fruits and vegetables in an urban environment due to the lack of land,' he said.
With a vertical greenhouse, 'we could have fresh organic produce every day and sell it directly to consumers in the city,' Hassle said.

That way, 'we would save 70 percent on the cost of fresh produce because right now 70 percent of the price is transport and storage costs,' he said. See full article.
