Geothermal Solar Greenhouse Climate Battery Supercharged (2019)

14 Comments



In this video, I’m going to show you how to
supercharge a geothermal climate battery for a solar greenhouse organic farm. Imagine, heating a greenhouse for free all
winter long. Stay tuned! SimpleTek, practice effective technology. I made this channel to experiment with simple
technology for agriculture and energy. Clicking the subscribe button tells youtube’s
algorithm you want to see more videos like this. Click the subscribe button now. the basic idea of any geo thermal climate
battery or earth battery is to collect heat from the inside of the greenhouse and store
that heat in the ground for use in the winter. climate batteries work best with what’s called
a solar greenhouse design. A solar greenhouse has a highly insulated
north wall and faces south to maximize sunlight in the reduced sunshine of winter in northern
climates. Supercharging a geo thermal climate battery
focuses the purpose only on heating. In northern climates cooling is simple, just
using vent and fans. The easiest way to supercharge a geothermal
climate battery is when installing the ground air vent is to add PEX tubbing, 6-8″ in the
dirt, above and below the plastic weeping tile air tube. A a rule of thumb, you’ll need 2X the length
of PEX as air tubes to supercharge a climate battery. So how does this PEX tubbing increase the
heat of an earth climate battery? Instead of just taking e heat from the inside
of the greenhouse a supercharged solar greenhouse climate battery uses heat from outside the
greenhouse to charge the climate battery using a device called a thermal solar collector. Basically we heat the liquid in the PEX which
additional heat to the ground which we can use. The PEX needs an outside heating source, and
the cleanest simplest option I know of is Solar evaporated tubes. A small circulating pump under 50 Watts transfers
liquid through the PEX tubing to the evacuate tubes all summer transferring the solar heat
into the ground storing it for winter use. The ground will slowly heat up, much more
than a conventual climate battery. A conventual climate battery can only heat
the ground to a maximum of 25-30′ C. A supercharged climate battery can increase the ground temperature
to as much as 70-80’C. Think about how much more heat that is available to be used on
demand by a thermostat delivered by your existing climate battery air tubes. Imagine, not just growing lettuce and spinach
but growing tomatoes, cucumbers, and peppers in the cold winter and having fresh produce
all year long without enormous heating bills. I hope you enjoye is video. Thank you for watching and please check out

    Post your comments here! I'll try to respond to everyone.

    People in governments need to know this. We can have less food scarcity, and less money going to trading if we just grow our own food. Thanks for the video. I'm really fortunate to live on Vancouver Island where the ground rarely freezes, but people need to know about this on the mainland, and east of the mountains.

    Ok where has this been done? The problem with this idea is there is no insulation in the ground around the pex and ground so it would not store the heat, much like heating a cave.

    You should do a Fahrenheit version.

  5. Enzo H says:

    when burying the pipes on the ground, should it be below the frost line ?

  6. Gary Sherbeth says:

    I always wondered how you could use a citrus in the snow greenhouse further notth where the average ground temp is colder. Thank you! I've always loved this video you linked to https://www.youtube.com/watch?v=ZD_3_gsgsnk By Kirsten and you seem to have added the needed second element for earth batteries to work in Canada and not just Nebraska!

    I watched your geodesic dome build video from a year ago. Do you have a video on the double-wall covering that you talked about? How is the dome working now?

  8. Artūrs Riekstiņš says:

    i whant to see thermodynamics behind this otherwise your given infformation is useless

  9. UbuntoO says:

    Wow wow wow!
    TY

  10. stephen besaw says:

    have you tried adding this to a standard climate battery? or is it just theory?

  11. Eclipse Rover RC UGS says:

    HowToFarmAndGarden.com a youtube channel has a good series on a geothermal greenhouse that is getting 50+ degrees year around from the climate battery from the ground only in NW Montana.

  12. Joe Clark says:

    where did you source the solar equipment?

  13. jack says:

    How is it working? Sounds awesome but it would be great to see it in practice. Also, how is your geodesic dome?

    Hi Simple Tek,

    5 months since your last post. I hope all is well. How are the greenhouse builds going? Cheers,
    Bill
