  1. Hello fellow farmers, i am here in Botswana in Southern Africa and the temperatures here can reach 40 degrees celcius during the hotest times of the year, so i want to know if this can work for me in these conditions and how i van make it work ? I also want to know the amount of perforated pipes i need underground to sufficiently cool and warm a 10mx30m greenhouse? Lastly regarding the perforations on the pipes, is there any spacing requirements between the perforations?

  2. $40,000 seems VERY expensive for a green house to me. You can build a heated green house much cheaper. Heat it with a partially buried wood oven fueled with wood from your own land. Fully organic, 100% bio and renewable. He admits that most of the money and materials were supplied by grants. Would you pay $40,000 for a green house in your back yard? I sure wouldn't.

  3. Couldn't have this been down with water? I dont know about where you live but here we have pool water heaters. Black pipe on the roof of the house, water heats up and circulates back to the pool thus heating the water. This principle can be used to heat the internal of a house with the pipe going to under the floor, I know they do this in England. Seems like a complicated way of heating the ground with air….

  4. Flawed, how much energy do you need to use to collect energy, Fan motors run ya….

    Use the thermal heat to heat up those bags of water then use insulated hoses to run water underneath the soil. No fan no pump…. and water retains more heat than air does…

    Stop smoking your brains out man

  5. Really liked the philosophy behind it. I'm from the Himalayas and planning to do something similar for my hydroponics project. I'm trying to learn how geothermal energy works and the challenge to conserve it for the night time when temperature drops below -10 degree celsius.

  6. How was it that the grant for this was secured? I have a similar project with a different design concept to address the colder ground temperatures here in northern Minnesota and am interested in turning it into a larger "open source" project.

    Great job on the project.

    I would also like to make note to others that are doing aquaponics and green house designs that you should try to stay clear of PVCs…

    PVC(polyvinyl chloride or vinyl) and CPVC(chlorinated polyvinyl chloride or vinyl) and the cement used to join it is not safe for food use, not safe for grow beds and not safe for aquaponics. PVCs contain known human carcinogens and they leach into fish tissue, food and the water when used in this environment. Many of the cheaper imported PVC's also contain lead, mercury and other even more harmful chemicals.

    People really need to stop using PVC for growing foods, to many people on youtube using it for anything from chicken watering and feeding to aquaponics setups.

    PVCs are not safe, do some research please.

  7. As per the comments about "profit", some minor good points he makes about the value of health, etc…but saying profit is a crude measure just is not realistic…money makes the world go around folks…sustainability and whatnot is a good catch phrase but to be truly sustainable it has to afford itself.

  8. one of the best method I used I use 900 degrees Fahrenheit oil on a 600 gallon with granite rock use the oil for solar transfer started heating oil you can storage it at very high temperatures great for hot water system it's not nothing a new idea I done at the New York City for a laundry mat true a hot water system oil temperature go up to 600 degrees Fahrenheit in the winter it produce a lot of hot water great saving for money the conventional solar hot water system you don't storage a lot of heat which is a major problem for high demand water system same principle for a greenhouse I did one upstate New York a prototype it work out exception and do you well in the dead of winter you could store lot of energy in oil granite use very high temperature oil with proper engineering

  9. Why not just have a geothermal heating and cooling system. It's very similar to that but with water rather then air like they are using. I don't really understand this I would think is less effective, but I'm not to sure the difference between the 2 methods.

  10. Hi, Food Farmer Earth! This is such a powerful video. Every thing we can do to spread the word on sustainable energy, we will support it. Thank you for sharing. Super Eco Kidz is a new Youtube channel. We would love for your friends to come check us out and invite them to subscribe to us, too.

  11. would water with ethylene glycol added to prevent freezing be a better medium for storing heat than air? a pipe running across the peak of the green house could collect the heat and a pump would come on and circulate as the temperature reached a desired point for collection to the earth?
