I got into a discussion with a guy about this contraption, showing him why it was impractical, and I couldn't get him to budge. He thinks this setup is how all farming will be done in the future. He's a techie who loves tinkering and building gadgets, but he has no farming experience and only one year of gardening experience with a small plot in his back yard. Apparently he doesn't like being outside and getting dirty either. I explained that this gadget won't hold up to the weather and isn't practical except in a special environment like on a space station, where it could indeed be very practical if the station was big enough and spinning fast enough to create artificial gravity. It might also be practical on a lunar base inside a lunar greenhouse - or maybe also on Mars.
When I was a kid, people in my area still had chickenhouses and gardens, now hardly anyone does anymore. Small scale farming or large scale gardening is dirty, uncomfortable, and sometimes involves a lot of drudgery. This inventor thinks he's found the solution and that soon everyone will be gardening.
