Are You a Solar Space Heating Cadet?

Spiral Sun, Okapi Fan Control Systems: Greenhill EnviroTechnologies Inc.

So, there is this giant fireball in the sky that we call the sun. It sends down oodles of powerful electromagnetic radiation upon us every day, and we mostly just use it to get a good tan.

We have all heard of solar PV panels that magically convert this solar radiation into electricity,

but have you heard of a different kind of solar collector that turns this awesome solar radiation into HEAT? 

If your answer in “…umm, no?”, then you MUST keep reading!

Your future, everyone else’s future and the future of Earth depends upon You learning more!

Solar space heaters (often referred to as solar air heaters, solar collectors, solar furnaces, solar pop-can heaters…) are insulated boxes with a black interior metal something-or-other and a clear polycarbonate (like that tough Lexan, plastic glass stuff) or real glass covering, mounted on a sun-facing wall or roof of a building.

They collect solar radiation and transform it into heat!

You know how when you wear a totally black outfit and sit in the sun you get super hot as compared to when you wear, oh, say, something very bright and reflective, like a white, sequined, disco jumpsuit? Well that is solar heating science at work!

There are two main types of solar air heaters: 

  • “Closed-loop solar air heaters”: With these, air from within the home or building is pumped through vents in the walls into the solar collector box, where it becomes really hot and is then pumped back into the building. Fantastic free heating!
  • “Open-loop Solar Air heaters”: These take the cold air from outside the building and preheat it before it is pumped into the building. This type of solar air heater is often used for large, industrial buildings that require extra ventilation. Definitely some free-heating, plus fresh air! (-assuming the air outside is not polluted)

 

Ok, Now You Need a Very Quick History Lesson:

The history of solar air heaters began a few decades ago with creative hippies going back to the land and doing all sorts of innovative and nutty stuff.

Hippies and Back to the Landers started making Solar Air Heaters.

They started building the original solar heaters which used no fans at all and relied upon the natural convection of heated air to flow from the top of the solar collector, through the upper vent and into the home at ceiling level.  But, this natural, hippy air-flow by convection is very minimal and not the ideal way to heat any space, especially NOW, with all this amazing technology at our fingertips in the 21st Century.

 

Alright, here comes the good stuff!

Greenhill EnviroTechnologies Inc. Logo

In 2013, along struts this plucky, young company from Canada, Greenhill EnviroTechnologies Inc., with an incredible invention called Okapi that has turned the world of solar heating upside-down, literally!

Turning the world of solar heating upside down. Greenhill EnviroTechnologies Inc.

Julian Jameson, creator and inventor of the Okapi Systems, was having fun YouTubing in 2012, and to his great surprise, discovered that the science of solar air heating was way, way, way behind the times.

Julian Jameson: Creator of Okapi Systems. CEO of Greenhill EnviroTechnologies Inc.

Jameson, who has a very cool background in computer and video game design and programming, in addition to electronics, realized how important it is to be able to control the flow-rate and direction of the air that passes through the solar collector box.

The result? 

-Good-bye, Hippy Passive Solar Heating.

Hello, Futuristic Active Solar Heating!

 

A bit of a ‘mad scientist’, Jameson thought actively blowing hot air out at the ceiling was pretty much pointless, too, and the world deserved much better. He determined that precise variable-speed fan control systems operating solar space heaters made them all heat a room better, and heat it more often! And so, he invented the Okapi Systems: variable-speed fan control systems that effectively heat a space by blowing the hot air out at floor-level and maximizing the solar heat harvest!

Sounds interesting, doesn’t it?

Well, it gets even better.

 

It turns out that we are polluting our precious air throughout all the cold months of the year around this planet burning wood, oil, gas, coal and sometimes dung. This air pollution from all this smoke is contributing to sickness and death, increasing the CO2 in our atmosphere and creating climate change!

We are all burning stuff to stay warm during the cold seasons, when on sunny or even just partial-sunny days,

 we shouldn’t be burning a darn thing!

Sick, Polluted Earth! Greenhill EnviroTechnologies Inc.

 

And so, off goes this daring, new company, Greenhill EnviroTechnologies, dancing around the internet with their crazy brand, “Okapi” (named after an obscure animal that hardly anyone has heard of: a cousin of the giraffe, but it has stripes and a much shorter neck). They had a successful Kickstarter Project in 2013 to finalize their first product line of intelligent, variable speed fan control systems, then had another successful Kickstarter Project this fall of 2014 for their new wireless options!

It turns out there are a lot of old, young and new hippies out there trying to change the world for the better!

Solar Flower Power!

In fact, there are thousands of people building these solar space heaters and putting them on their homes, log cabins, cottages, garages, workshops, barns, sheds and doghouses! And now, there are actually commercially available solar air heaters! Yes, you can go out and buy one! Except, their fan control systems don’t hold up when compared to the patent pending, innovative features of the Okapi Systems. Eventually, all these commercial solar air heaters are going to have to have Okapi Systems operating them in order to optimize their solar heat harvests.

 

DIY Solar Heaters: Are you up for the Challenge? Greenhill EnviroTechnologies Inc.

 

Alright, you are feeling like you have learned something new, now, and that always feels pretty sweet. It gives you hope for a future with less pollution, a healthier planet, and yes, you could save a lot of money on your heating bills, too! (And, wow, aren’t those heating bills getting outrageous?!)

 

Solar Air Heater Building Season! Greenhill EnviroTechnologies Inc.

Our Living Family Heirloom

 

 

Spring has its delights.

The pussy willows beckon to be petted, fiddleheads curl me batty, spring-peepers drive Julian nuts

and songbirds serenade us all day long.

Spring can seem so incredible that it can be a wonder how we survived the winter.

Spring is also that time of the year for mother’s day, father’s day, reunions, weddings, births, birthdays, graduations and gatherings: an exhilarating season!

Yet, what I love most about spring, is watching my family heirloom start to blossom.

It lives in our bathroom: a warm, moist environment, perfect for her tropical roots. She gets plenty of eastern morning sunlight, and spends all winter tenaciously growing long tentacles, that once having reached the ceiling, then begin crawling across it.

Spring is all about nurturing the next generations and revering the past generations.

I am usually not one to dwell too dearly on things like dresses, blankets, photos, old plates, jewelery, watches and paintings, yet I do absolutely cherish these objects from my family’s past. I love imagining the people who came before me using and living with these objects and then deciding with deep gravity to pass them on to the next generation.

An heirloom, a thing that shackles a family history together, is a chain of love and care.

The most important living family heirloom, which I might cherish even more than this remarkable plant that lives in our bathroom, would be my chain of genetic code.

Your DNA can be a strange concept of an heirloom to grasp, unless you simply hold your own hand.

My family genetic code is full of wonderous and frightening things:

strange abilities in academics, the arts and athletics; perseverance and dedication in almost everything we attempt; outstanding levels of compassion and empathy; yet also with startling amounts of sadness and despair that have terminally gripped too many of us by the throat; and then there are those mysterious, incurable  diseases that have left a few of us with joint, skin, belly and neurological problems…

Our 100 yr-old “night-blooming Cereus” plant is our living family heirloom.

Our night-blooming Cereus has spanned up to 5 generations in our family. My great-great-grandma acquired it on her travels and handed down a cutting of it to her daughter. (Take a single fat, juicy leaf from a Cereus, stick it in some soil and soon you have your clone.) She then passed a cutting from her plant down to my Grandma. Grandma’s grew large and strong, also. She passed down a cutting from hers to my parents.

I received my cutting from my parents’ plant in my early twenties as a celebration of living semi-independently.

Receiving my piece of the family heirloom was a very precious milestone.

I stuck that leaf in the soil, added water, watched and waited. It has grown into the strongest looking Cereus plant I have seen so far: luscious and green, fat and juicy (as compared to my sister’s cutting, my parents’ and my grandma’s). I think it does so well because I have pruned it frequently or more likely, I have just been very, very lucky.

We often get 7-9 blossoms a year, which is quite a privilege when raising this tropical plant (even though it is always indoors) through the bitterly cold winters of Nova Scotia.

Growing up with my parents’ tentacled plant was fascinating. We got to stay up late on the nights it bloomed, celebrating, watching and smelling it unfold. But our old farm-house was chilly and well shaded by giant trees. Their plant only bloomed about 1-3  times a year, if we were lucky. Its leaves have always been a little narrow and pale.

So here it is: a little piece of my ancestry.

This was taken yesterday, the morning before the first blossom of 2014.

Then came another gorgeous, spring sunset, but my attention was elsewhere:

for as night falls, the Cereus opens.

It remains open all night, emitting an intense perfume that fills the house.

For a night-bloomer, it has an unusally pleasant odor: fruity and fresh, flowery and kind.

It creeps open into the early morning, hitting its maximum size just after midnight.

Everyone smiles and seems excited. My step-daughter swoons, the dogs are cheerful and relaxed. Julian then sleeps so deeply and peacefully, it is as if all is simply perfect in our world.

It makes me feel absolutely elated: full of tinglings of love, gratitude, exuberation and generous satisfaction.

The aroma could very easily be mildly intoxicating. Some say extracts from the plant and its fruit can cause mild hallucinations (we have yet to see ours make any fruit), and were once also used to treat heart conditions.

A relative of the dragon fruit, the Cereus, a type of cactus, also known as the “Queen of the Night”, is exotic and full of mystery.


By sunrise, it closes.

It is done, spent, exhausted and limp.

I imagine the whole plant is resting very deeply today, after such an energetic night.

The night the Cereus blossoms is always a monumental event:

it is a night to remember all who came before us and all who may come after us.


May we all leave a legacy of compassion and empathy:

one that smells sweet and clean,

that is beautiful to behold,

and most importantly,

 strong and enduring. 

And there are more to come this year!

Already, another bud is beginning to grow!

 

Making Strides

Here is a post I wrote back in February, 2014.  I had a very ponderous day.

making strides copy

Salt Springs Provincial Park, Pictou County, Nova Scotia, Canada

If you had the choice between making many, quick, short steps or making few, slow, long steps,

which would you choose?

I have tried both ways.

 

Making many, quick, tiny steps was loud. My feet made sharp scuffing sounds as they hit the ground. My whole body worked hard with each step and my breath was frequent. My snow-panted legs swished against each other piercingly, my arms snapped back and forth vigorously to keep up my momentum. I was expending a lot of energy and felt a strong sense of vitality. It was exhilarating, fun and enlivening. But, I also noticed, with all this noise my crunching feet and swishing clothing made, that I could no longer hear the birds or wind. I was concentrating so hard on moving and moving quickly that I lost track of the trees and hardly noticed the dogs running around me.

 

Making fewer, but longer steps felt smooth and stealthy. My motions were eerily quiet. I could hardly hear my steps. My body was calm and relaxed, my arms barely needed to swing and my breathing was stately. I heard a raven calling across the field, I saw the dogs racing and chasing each other. I felt the wind and I marveled at the trees slowly drifting by.

 

These two ways of progressing are completely different, and both essential to practise at different times while on a walk, in life and while starting a business. The quick, short steps are invigorating: they get the heart racing and the mind focused. The slow, longer steps are restful and allow for observations and creativity to flow.

We successfully completed our Kickstarter Project for “Okapi: the Intelligent Fan Control System for Solar Air Heaters” in November, 2013. It was an exciting experience full of very busy days, a lot of good noise and many short, quick accomplishments.

 

Now, we are taking slower, longer strides with our business. We are thoughtfully meandering the legal territories associated with bringing an electronic product into the market. The previous quick, short steps we used in announcing ourselves and gaining public awareness were exhilarating and awakening to our spirits. Currently we are calmer and quieter, learning, researching and creating so much along the way. Yet, soon, we may quicken our steps, again!

As much as I want everyone to have solar air heaters on their houses NOW, I accept that getting this technology into the minds and hands of the general public will take time. It will take many, quick, loud and small actions, combined with fewer, calm, large actions.

With time, we will reach our goal, our destination: our Greenhill vision.

This vision is beautiful and kind, sweet and relaxing. It is a place where the air is clean, the land is not disturbed, the hillsides are vibrant with wildlife, yet everyone is still warm and cozy.

And the Geese Return… Happy Spring!

Those special DIY backers will be receiving their Okapi Systems very shortly as we finally smooth out the last tiny legal details of our electronic product distribution abilities. We have been so very thankful for the kind patience.

We, ourselves, have been quite frustrated about how long it has taken to figure out all these details, but they make the process a difficult and meandering one for a very good reason: consumer safety! None of us want some dangerous person soldering electronic products in their basement and selling them on the internet without them being checked-over by officials and standards agencies to ensure they are safe for use, meant for their intended use, and comprised of safe and certified components. So the long certifications, standards and guidelines process, though frustrating, is something for which we should all be grateful!
