The Winter Greenhouse, grow in -40'C  (2020)



A 4 season greenhouse designed for deep winter conditions that takes solar heat from the summer, stores it, and then uses it in the winter as needed. Designed for a small businessman selling roadside or in farmer’s markets.

  1. I'm still a bit skeptical about how much they're getting out of what's stored over the summer. The surface area of all the garages, combined probably just about keeps up with daily heating needs when the sun's out. That big water battery's probably enough to tide them over when skies are gloomy, but I'd need more data to pass judgement on how much they actually get out of the summer heat during the winter. Seems like something that'd attenuate over the span of a few days or weeks, unless they kept pumping more heat into it, which I imagine the passive solar system does. It's not like it stops working just because it's winter. It just stops working as well, because the sun's so low. I'd also want to know just how big and just how insulated that water battery is.

  2. Good work but you made a big mistake geothermal does not store heat from summer and release in winter !! no material will dissipate heat that slowly.. you mean store in the day and release at night when its colder this makes more sense

  3. The way this is presented is basically quackery. Do the BTU calculations yourself, and you will see what I mean. The heat storage that a realistic thermal battery can store wouldn't last 2 weeks, much less all winter, before it's completely depleted. Adding evaporated tube solar collectors will give you enough heat for the day if you have several hours of bright sun during peak hours, but we know how much sun there is in canada during the winter.

  4. This is a proven idea with low cost DIY products in market, you can go visit China and experience yourself, on the way back you can purchase your own DIY kits with installation manual.

  5. It's worth noting that the Drake Landing borehole system is absolutely massive. There are 3 boreholes for each house, With each borehole serving a column of about 6.67 meters in area and 37 meters! deep. That's 1300 tons of earth per house in the battery. Also worth noting that most of the heating needs are still met by the solar collectors in the winter, the battery is just to bridge the gaps when the hot water storage tanks cool off late in the night and when storms roll in during the days.
    Edit: They also still use natural gas when their system is unable to deliver enough heat to handle long storms, or more frequently when they want to warm water. https://www.dlsc.ca/about.htm

  6. I don't trust anything that starts with the Chinese are having great success , I've learned hard lessons with this virus that started there and amazing success of infecting the world!! For all I know this is paid by Chinese government propaganda.

  7. Unfortunately this would require a exorbitantly high capital investment, defeating the notion that individuals and small business owners could afford the upfront cost. I lived in a net-zero laboratory house while getting my master's in mechanical engineering and was specifically focused on evaluating and designing methods for growing food crops on a small scale in a sustainable and affordable manner. Geothermal and thermal batteries are wonderful technology but their effectiveness (particularly in very cold climates) is largely proportional to the amount of money you spend…. For anyone in need of a crop-growing method with low capital investment, I suggest something like hydroponics 🙂 The cost savings in produce grown from seed with this type of system vastly outweighs the operation costs of red-blue LED grow lights and an aeration pump. (And hydroponics can use as little as 10% of the water used in traditional farming, so you save there too!) You can also design your system to be vertical, so that it takes up less space in your house. Happy gardening 🙂

  8. Sounds temptingly good. All you need is one thing: SUN. After half a century of living in Alaska though, I came to the realization that the sun is frequently obscured – kind of like an inverted wall to wall carpet – by boring grey clouds. Does make one wonder what is meant by 'down to -40º.
