Thread: Giant pot plants popped up overnight, so what else could we build?

    Default Giant pot plants popped up overnight, so what else could we build?

    So in just a couple years Alberta has seen the construction of huge marijuana grow ops. Massive buildings!!!!

    So what else could we be growing here rather than importing the produce or products and thus draining our economy of our oil-based wealth?

    Fruits (fruit trees)
    Nuts (almonds?)

    Bamboo ? (Though can’t imagine this would ever be cost effective)

    For years I've thought that greenhouses should be built next to powerplants in order to capture the waste heat they produce.

    I agree. Always thought that instead of cooling towers wasting heat at refineries and power plants, heat nearby homes and build greenhouses. We need to ctreate jobs by integrating 4th generation cogeneration plants.

    Waste heat, much?

    Fourth Generation

    Currently, the 4th generation is being developed[4], with the transition to 4th generation already in process in Denmark.[6] The 4th generation is designed to combat climate change and integrate high shares of variable renewable energy into the district heating by providing high flexibility to the electricity system.[4]
    According to the review by Lund et al.[4] those systems have to have the following abilities:

    • "1. Ability to supply low-temperature district heating for space heating and domestic hot water (DHW) to existing buildings, energy-renovated existing buildings and new low-energy buildings."
    • "2. Ability to distribute heat in networks with low grid losses."
    • "3. Ability to recycle heat from low-temperature sources and integrate renewable heat sources such as solar and geothermal heat."
    • "4. Ability to be an integrated part of smart energy systems (i.e. integrated smart electricity, gas, fluid and thermal grids) including being an integrated part of 4th Generation District Cooling systems."
    • "5. Ability to ensure suitable planning, cost and motivation structures in relation to the operation as well as to strategic investments related to the transformation into future sustainable energy systems".
    Calgary is doing it...


    District Heating is becoming a growing industry in Canadian cities, with many new systems being built in the last ten years. Some of the major systems in Canada include:

    • Calgary: ENMAX currently operates the Calgary Downtown District Energy Centre which provides heating to up to 10,000,000 square feet (930,000 m2) of new and existing residential and commercial buildings. The District Energy Centre began operations in March 2010 providing heat to its first customer, the City of Calgary Municipal building.[82]

    I’d guess that it’s way too late for Edmonton to build a district energy system. It was proposed and rejected by Edmonton decades ago and obviously there wasn’t any buy-in back then so I can’t imagine how there’d be significant support for it today. Our downtown has been transformed since the 1980s so I would guess that tying any new system into all the new buildings and towers would now be far more costly than had the infrastructure been in place before construction. Also the newer buildings now in place have their own systems that are likely far from being in need of replacement.

    I’m back. Interesting:

    I always eyed the townhouses in Goldbar as an example.

    The needs and opportunities have changed and the technology and economics behind cogeneration of various projects have been tested and are well known.

    While the heat would be nice, it's electricity you really need to grow those thing. We get a lot of sun in the summer, but not so much in the winter. so you need lots of light to grow things. And even with efficient LED's that's a lot of power. Some greens like lettuce, spinach, microgreens don't require a lot of light to prosper, but still more than can be provided naturally around here. You get in to fruits and nuts and it would never be economic to grow those in greenhouses year round with the type of light they need.

    Virtually every major industrial facility has a waste heat/energy recovery system. It's a question of economics and the environment. If it's economical to recover the waste heat, it's recovered. The heat coming out of the top of the stacks is actually a function of environmental regulations and the plants get in trouble if the outlet temperature is too low. A smokestack is actually the last vessel in the incineration process. In a refinery, they burn waste gasses in an incinerator that leads to the stack, the combustion process is ongoing as the waste goes up the stack. A stack is much more than a tall tube that gets the pollution high up in the atmosphere. There are a large number of factors that go into stack design, the most important being the time required to properly consume the pollutants to render them as harmless as practical before they enter the atmosphere.

    Default Edmonton cannabis plant part of Canadian push for global business

    Radient has gone from 18 employees in 2010 to 100 right now. By next year, it will have as many as 200.

    The company is built on microwave processes and technology developed in the 1990s by Environment Canada. At first the tech was used to extract ingredients out of plants for lab analysis. Splinter started Radient to look for commercial applications. “Our business is converting natural organic matter into valuable ingredients,” he says.

    'It's a blizzard outside and we're growing lettuce': Busby area farmers grow vertical | CBC News

    David and Alyssa Pfaeffli of Swiss Leaf Farms have been growing lettuce, microgreens, and herbs in a 9,500-square-foot warehouse for the past couple of months. The system they are using will allow them to grow year-round.

    The farm just had their first harvest last week and have delivered greens to grocery stores in Westlock, Barrhead and Edmonton.

    "We can provide the same produce that's fresher, tastes better, it's healthier and there's zero pesticides. It's better for the planet," said David Pfaeffli. "You're not driving a diesel rig all over North America to deliver lettuce."


    Financing the vertical farm was the biggest challenge for the couple, said David Pfaeffi. Without large farming equipment, he didn't have a lot of collateral if things dried up.

    "Agricultural lending outfits weren't too eager to lend a large sum of money on equipment like this because they'd have a hard time recouping their costs. It's not a combine," David said.

    Space tech that feeds high-end diners in Toronto could help Canada's North

    “The vertical farm of We the Roots is a commercial test of the new tech. The most traditional farm-like thing about it is the pickup truck parked outside.

    The structure inside a former factory is roughly 14 metres long by three metres wide and four metres tall. It houses from 15,000 to 20,000 plants at a time. "We're growing wild Italian arugula, mizuna, which is a Japanese mustard green, Tuscan kale, basil," Jadavji says, "and a little bit of cilantro."

    We The Roots wants to try the system Dixon helped create in the North, but it will be tested in extreme heat before severe cold. Why? Because Kuwait is willing to invest in it.

    "It galls me, quite frankly," says Dixon, "to think this Canadian technology will find its first expression in a large-scale pilot in the deserts of Kuwait."

    How this greenhouse grows food all year using goldfish and the sun
    June 2019

    Growing tomatoes in February in New Brunswick might sound like a fantasy, but the Ville Cooperative in Fredericton and a University of New Brunswick PhD student have made it happen.

    The greenhouse is heated with passive solar and geothermal techniques, which keep the temperature at around 30 C even on the coldest days in winter.
