The Israelis are doing it profitably-— even more profitably than field-agriculture, because of the very efficient use of water, and the elimination of waste, which otherwise typically accounts for 1/3 of the crop from field to consumer.

That's totally believable... but I suspect the group in Philadelphia might not be up to Israeli standards...

Then again, if they are it would be wonderful... Nice opportunity for the city and for ‘farm to table’ restaurants and markets.

Thanks for sharing.
