Green Meat: Medium Rare

Brendan Koerner questions whether lab-grown meat would be environmentally friendly. The prognosis? Maybe, but not anytime soon:

...don't hold your breath while waiting for your first lab-grown roast. Despite considerable hubbub over the technology in recent months, we're still yearsor, more likely, decadesaway from affordable lab-grown meat. The current experiments are taking place in bioreactors that measure only a few hundred milliliters in volume, and the longest complete muscle tissues are just 2 centimeters long. Researchers are nowhere close to scaling up their production to market-ready levels, to say nothing of market-ready prices. A Dutch team's lab-grown pork, for example, would cost around $45,000 per poundassuming they could make an entire pound of the stuff. Bioreactors may be energy-efficient when compared with cattle, but they're also expensive to design, build, and maintain. They also require highly skilled personnel to manage, in order to preserve aseptic conditions.
