Geothermal Solar Greenhouse Climate Battery Supercharged (2020)


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

  1. 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.

  2. 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.

  3. 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!

  4. 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?

  5. 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.

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

  7. Hi Simple Tek,

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

  8. Are you insane? 80 degrees Celsius converts to 176 F. You would destroy all soil biology at that point. Worms and plants do not like temps well beyond 82 degrees F.

  9. Store it in the ground from summer all the way through winter? No. Your said system would help make it warmer but it will be inefficient. The ground conducts heat and is constantly losing any additional heat in the system to the surrounding mass. Nearly all energy generated in the summer would be long gone before winter. Solar thermal operates at a max 190' F (temperature at which glycol breaks down) which means if it did get the ground to this temperature it would have to dump all remaining heat to the air. Any plants planted in the ground would have their roots cooked. Earth climate batteries are, in terms of heating, only good at keeping greenhouse temperatures just over freezing. For your solar thermal, it would only be beneficial during cold months. The system would be cheaper and more efficient to pipe the heated water into a water storage tank that is located inside the greenhouse. This eliminates heat loss to the surrounding earth because all heat loss is released directly into the greenhouse where you want it. This would also afford additional thermal mass to further regulate the temperature and require far less hardware. Expectations should be that the amount of solar thermal collectors installed generate as many BTU's as your daily loss at the desired temperature or the system will not live up to the hype. Additional consideration should be given that the amount of water storage for your heat is adequate to store (and release!) what you generate daily.
