A proof of concept ecoCity Farm has been established for some time with a fully operational, semi commercial scale system on UES’s research farm in Northern NSW, and has been selling produce to the wholesale organic markets for several years.
So there's a sense of scale for the poster of the question...
And here's a sense of the "financials"... or at least those pertaining to this system...
Quote:
UES will initially sell complete farm units, including hardware, installation and commissioning at a price of approximately $3 to $15 million, depending on which particular option and configuration is purchased.
....
In addition to the sale of units, the company will retain ongoing revenue streams from royalties, technical backup services, and the supply of consumables.
