I can't remember which department the professor was from, but he described a method of using the heat from soil, I don't mean in-ground heat pumps, but a method using solar energy. The exact method he described had been tested by students from a university in Colorado to heat a greenhouse .
I raised my hand, and mentioned as much. I asked, why couldn't this system be built into new houses. He replied, "What about existing housing?" His tone made it clear what he meant. He didn't mean, but shouldn't we do something for existing housing, he meant, it would be unfair to people who are paying for their heating and his students paying for their education to service the need for heating.
Why an ETS system is better than an in ground heat pump is simple. Because installing is merely putting an aluminum tube from the ceiling and directing it into the ground which acts as a thermal mass. This is the exact opposite of a heat pump and uses heats insistence on rising, and aluminum's ability to transfer heat. It doesn't use a pump, or refrigerant. And the only excavating required for installation is being excavated anyway to make the foundation, where a heat pump needs 15k worth of its own excavating to gain enough heat. This and a few other things helped keep that greenhouse in the 50s with no heating bill even when it reached -20 outside. There are a few other ways of heating your house for free and and could be added to the design of the house at little extra cost.
I met a guy the other day and we got to chatting. Other are thousands of these guys around here. They have the right combination of cheap and creative, and fairly well to do in general. He made his own biodiesel for his tractor and was lamenting the need to heat it over 300 C. He was an older guy, so being the quiet guy I am, I mainly listened.
He had a few interesting thins to say:
I don't know why there's all this fingerpointing at China, it's all Western companies that tell them how to make their products and with what and that's what causes all their pollution.
The housing code in Canada is only there to protect industry from competition.
I have been trying to build a hemp house here. At the permitting office, they said, sure you can build it if you can get a engineer to sign off on it. I asked if a foreign engineer would do. Nope has to be from Nova Scotia and he has to base his experience off of Nova Scotia housing.
What that means, is if it hasn't been built here, it can't be built here. Nothing will ever change.
Why do I write all this? Well, we have over time even put a price on water, and now you suggest we do so with air. It doesn't matter what price you put on it in the beginning, because eventually, it will just go up until some are priced out of the market. You can take in all the oxygen you want, but exhaling means you're braking the law.
My real question, France, England, Canada, US, Australia all have hemp housing. According to the studies, it is carbon neutral because the carbon emitted in its construction is absorbed by it in its lifetime. It also reduces energy use in half. It is also dirt cheap to make. We have seen houses with such claims in the past. In general they run into code problems, or are built as experimental housing that can't be lived in or sold.
I have a 9 bedroom house built by one of the officers in charge of making the Acadians Cajuns. It was not built with a permit, or according to code, and yet still stands as long as the USA has. It costs about 6k a year to heat. Under the new energy prices, that will go up 20%.
I have studies conducted independently by more than 20 universities on 4 continents, including Canada. All have tested the structural qualities, R values and others conducted a variety of different tests.
The government will not permit me to use hemp to renovate and cut my energy bill in half. It is a heritage property and cannot be changed on the outside, limiting my ways of making more energy efficient with conventional materials and upping the cost by 900%.
So should I pay the extra carbon tax, and heating costs or the 900% more expensive, off gassing method? And I don't care about the economic perspective, I ask you to tell me from a moral perspective.
