I cannot fathom why we have large scale, highly efficient meat production facilities (remember: animal rights are only relevant to hippie tree huggers), yet there's virtually no commercial efforts to harness plants. The technology exists [0]; I don't understand what the practical or political problems are. I think small scale plant reactors have the potential of being able to be manufactured very cheaply; maintenance is probably the issue, but I'd like to hear from an expert in the field.
