Mad scientist's homestead is parking size, off-grid system

Mad scientist's homestead is parking size, off-grid system

Former Army tech Larry Johnson has spent his career improving computer and telephone systems so when he saw inefficiencies in how we grow our food, he decided to create a new system for farming your yard. His EZGro garden uses aquaponics, stacked towers, and custom pots to create a high-density vertical garden (HDVG) on as little land as a deck, rooftop, or parking space.

Johnson says the system will grow 700 plants, using 15 towers, in a space of just 2 by 18 feet. Today, he sells kits ranging from single tower patio gardens to 10-tower deck gardens to commercial-sized set-ups like those being used by a Miami football stadium for concession meals, by a Whole Foods Market in New Jersey, and by rooftop farmers in Lagos, Nigeria.

It all began in 1995 when Johnson began tinkering with his quad pot design, crafting a custom container strong enough to hold tomato plants with over 100 pounds of fruit. He then developed an irrigation system that feeds nutrient-rich water from the top of the towers, drips through the pots, and filters out through tubing below to be reused. This closed-loop system uses less than 10% of the water of a traditional garden.

To create a system robust enough for even off-grid farmers, Johnson has spent the last 2 decades developing his trihelix solar windmill. Solar panels are mounted on top of three turbines, known as the “Tri-Helix”, which are twisted like DNA strands to catch even inconsistent wind (turbines start turning in winds of just 2mph).

    This man is a true hero! Bless u sir!

    Living legend, basically a one and done manufacturer with design transparency. He may or may not care about being a millionaire but he deserves it.

    I love watching your videos! It’s really inspiring and gives me hope for the future. I love seeing ‘regular’ folks learning how to save our planet.

    want all my salsa fixings here….hmmm….nice…

  5. Robert on July 28, 2022 at 11:55 pm

    how many tomato plants per pot

  6. mike g on July 28, 2022 at 11:57 pm

    Impressive set up… so how do those tomatoes taste?

  7. Ethan8 on July 28, 2022 at 11:58 pm

    If you’re interested in these types of vertical-axis windmills, be sure to search a bit for: "Savonius wind turbine". This will show you examples of similar turbine designs, which can you even make as a small science project using e.g. a Pringles tube or a (a bit more "serious") using a small section of rainwater pipe. 🙂
    Note: make sure you stay safe though! When there are high wind speeds. Under high load (and when no braking/safety mechanism is present) parts can go flying when a wind turbine hasn’t been designed/constructed properly.

    Who is this guy? More videos of him please!!!!

  9. Pierre M S Silva on July 29, 2022 at 12:03 am

    I could watch a 2 hour documentary on this guy.. dang!

  10. The3rd1inLine on July 29, 2022 at 12:03 am

    Is it possible to use organic nutrients in a system like this?

  11. The Valley Spirit on July 29, 2022 at 12:04 am

    Very cool, if the goal is fast efficient food is the goal 3d printable parts might be a good move. Half a dozen machines hoses, plastic totes, and a pump could be all you need.

  12. JohannVonDiesel on July 29, 2022 at 12:04 am

    The only thing that he is missing, is fish. Aquaponics would be the way to do this more properly.
    This man get’s it. You follow the patterns around you.
    The first electric motor / generator ever, was an Axial Flux design!
    1821 Michael Faraday (British Physicist and Chemist) developed a primitive "disk motor" an axial flux machine.

  13. Golden Ratio on July 29, 2022 at 12:05 am

    Love this video

  14. Gregory Fantastic on July 29, 2022 at 12:05 am

    Dude had to have a lot of liquid cash to dump into all this non hand made stuff.

  15. Birdboy Entertainment on July 29, 2022 at 12:06 am

    Yeah He’s Mad

    Amazing, his tomato’s are like grapes. Worth the investment

  18. Javier Üskára on July 29, 2022 at 12:09 am

    this guy is a genius

  19. T R on July 29, 2022 at 12:10 am

    The doc brown of food growing

  20. Micah Robinson on July 29, 2022 at 12:11 am

    how can we get in touch w these people? they don’t answer emails, fbs, igs, twitters, yts, etc…

  21. Dale Benjamin Berger on July 29, 2022 at 12:12 am

    How can I contact this company?

  22. Jan Liljeberg on July 29, 2022 at 12:14 am

    Where can I buy this in Europe? Where do I get more info?

  24. Iced Mocha on July 29, 2022 at 12:20 am

    6:12 I literally can’t take anything you post serious, every time there’s a half assed split in the audio to cobble together something out of context.

  25. Michael Jordan on July 29, 2022 at 12:20 am

    Wow, simplicity outperforming complex systems, what a great mindset he has.

  26. BaldGirlGoneBold on July 29, 2022 at 12:22 am

    The rich education…💚💚💚

  27. Pablo Herman on July 29, 2022 at 12:24 am

    This is invaluable information on how we can rebuild society.

  28. Pilot Pilot on July 29, 2022 at 12:28 am

    Come on this wind turbine are produce less powe than your own dna chains.

  29. 4nrgy technologie on July 29, 2022 at 12:30 am

    this guy doesn’t know what he is talking abt. as far as turbines it’s been proven this savonius design like he is using has 6-7%efficiency, standard 3blade HAWT (horizontal axis wind turbine) is 45% efficient. Thats why noone ever build savonius for commercial purposes. although it’s easiest to made it’s useless in power generation

  30. LetsGo Brandon on July 29, 2022 at 12:30 am

    This is so cool. Now to combine a greenhouse with it would make it that much cooler.

  31. Moesbi Santana on July 29, 2022 at 12:31 am

    next lvl shit bro

  32. DVD JNS on July 29, 2022 at 12:31 am

    His internet solution looks like Teletonica made in Lithuania very good system some you can put in multiple simcards and add extra antennas

  33. Fish Mud on July 29, 2022 at 12:33 am

    The guy could grow some real nice weed! 😂

  34. Deb Victoroff on July 29, 2022 at 12:33 am

    I was hoping he was going to say "Flux Capacitor" at some point.

  35. D Touche on July 29, 2022 at 12:34 am

    Where can I find "his" tri helix at to get started?

  37. Homestead Development on July 29, 2022 at 12:35 am

    We just started our homesteading channel. Right now it’s all dirt work on our 27 acres but we are ready to start with everything else. If you’re ever interested in helping us out we’d love it! Thanks for sharing all of your information. Check us out when you get a chance and tell us what you think 😁

  38. Grace on July 29, 2022 at 12:35 am

    Wow, this bloke is absolutely brilliant

  39. Quick easy guitar lessons on July 29, 2022 at 12:36 am

    What an amazing man. You can tell that he’s so excited and happy engineering this stuff. Optimizing and making things more efficient. God bless you sir 🙌

  40. John Todd on July 29, 2022 at 12:37 am

    Does he have a website how do I find his stuff so I can buy it for myself both the planters and the turbines

  41. Noah Riding on July 29, 2022 at 12:40 am

    The wind spinny turbine design you are using… is it possible to run a household off those and have it actually work with a small amount of space?

  42. The Cannasseurs on July 29, 2022 at 12:40 am

    so sad, all that thriving soil and not a single cannabis or hemp plant..

  43. King Masterlord on July 29, 2022 at 12:40 am

    I want to make something like this deployable from a shipping container with like maybe a couple of Boston Dynamics spot robot type things. Maybe set up a foundation to make one for every homeless person in America and get them jobs making more to send overseas

  44. greenrocket23 on July 29, 2022 at 12:42 am

    We need a few billion of these systems everywhere.

  45. Sandy M on July 29, 2022 at 12:42 am

    This guy is brilliant! Seriously he’s on another level. I’m definitely buying his system for myself. Thanks for sharing.

  46. N1mBUS Music on July 29, 2022 at 12:42 am

    if it could use only rain water THAT would be the best. also whats the nutrient? I’m dubious of how things are fertilized in hydro.

  47. Kenny Williamson on July 29, 2022 at 12:44 am

    i saw this guy years ago and wrote to him, never replied. His windwill dna shape i remember him saying he could get 400 watts off each. Thanks for putting this up, now i have foundhim again.

  48. Alex Pires on July 29, 2022 at 12:44 am


  49. Greg Ripplinger on July 29, 2022 at 12:47 am

    So much half truths and poor application of resources. His speech is inaccurate for the most part. The growing of plants is the best part.

  50. Linda Williams on July 29, 2022 at 12:49 am

    This is awesome! Props to this veteran for taking his gift and giving us wonderful options!
