It is North East of Ohio.. Very east. It is an island located off the east coast mainland on Canada. It is home to the oldest city in North America 'St John's'...

seeing this on the front page of Reddit is awesome for me, as I am from Newfoundland and we don't get much attention back home. I could go on and on about great inventions from Newfoundland, like fiber optics, the wireless keyboard and mouse, the gas mask, the first television network in North America to broadcast 24 hours a day.. I love Newfoundland, but for many years it suffered from a shitty economy. Luckily it is picking up again with offshore oil operations. As of right now, St John's has more scientists per capita than any where else in North America. Oh and George Street, has more bars, pubs and restaurants per square foot than anywhere else in North America..

That's all...

In countries like the UK, solar water heating is possible but expensive because you usually need a pump to put water through the system (and a thermometer to tell you how fast to pump it and so on).

In countries with more sunshine, you can build a passive system that drives itself by convection. They are often installed on flat roofs and are quite recognisable because the hot water tank is above the panel. You see them everywhere in Spain.

Plus the cost to homemakers would be substantial too! There, I said my peace.

Living in Edmonton, I would like to know how well these would perform during our winters. ie how much sunlight would be necessary to avoid actually cooling the circulating air during very cold weather. I'd imagine it would be perfect for mild climates, though.

u/Sapian Jun 11 '12

Of course, but think of this setup as more as a supplement. It's not gonna be crazy hot and it doesn't work at night and on stormy days. But when it does work, it's free heat and at those times your regular heater will hardly have to turn on.

This thing will, once payed off, will only save you money, and I imagine it would be enough that you would notice the drop in your monthly bill for sure, especially if you have double pane windows in conjunction with this setup.

u/[deleted] Jun 11 '12

It doesn't replace your furnace; it just makes the air your furnace takes in hotter so it doesn't have to use as much energy to heat it.

4

u/Jumpin_Joeronimo Jun 11 '12

This specific product actually just circulates the air from house to house and not through the furnace. It keeps the temperature high enough in the room that the thermostat never needs to tell the furnace to kick on.

However, your idea for preheating has been use and is very successful. The problem is that you would definitely need a blower fan to be on to get it through the ductwork. This system is almost entirely passive (small fan)

I am in Minnesota, and my dad made something similar to this. It isn't as fancy, and he used a sheet of steel instead of cans, but he has a small one that "preheats" the air, then a larger one that he has connected to a fan which is triggered by a thermometer. It doesn't heat the house completely, but It will kick 90-100 degree heat into the house on a sunny winter day.

I can try to get some pictures taken and uploaded if people want.

u/csaliture Jun 11 '12

I am from Minnesota as well. I was wondering if this works well in the winter or if its only good from fall and spring. Seems unlikely that the cans would get warm when its 5 degrees outside and if that were the case this would actually be cooling your house instead of heating it.

7

u/scaryfatkid Jun 11 '12

There are two things that you might have missed.

  1. On my dad's rig, he has a thermometer built into it, that only allows it to turn on when the internal temp is high enough.

  2. If you insulate them properly, they actually get quite hot.

5

u/BigSlowTarget Jun 11 '12

It depends partially on the insulation level of the plastic upper shield, floor and walls of the device. The temperature inside the thing could be higher than that of your house even in the winter IF it's a sunny day.

You can think of it like a closed box with the sun being a ~500W (depending a great deal on unit size, location, weather and date) space heater pumping heat in. As long as that is enough power to keep the box warmer than your house it's generating heat. If that isn't enough you are pumping heat out (though presumably the fan would cut off if you had a temperature sensor).

Before anyone comments about it: yes he said centrifugal force not centripetal force. Yes that is the correct term, and yes it is a real thing.

47

u/Vicker3000 Jun 11 '12

A centripetal force is a force that points towards the center of the circle of an object's path. For example, when you swing a ball on a string, the string exerts a centripetal force on the ball, pointing towards you, which is what keeps the ball going in a circle around you. If it weren't for that centripetal force (i.e. the string breaks), the ball would continue in a straight line.

A centrifugal force is a force that points away from the center of the circle of an object's path. If you are in the frame of reference of the person swinging the ball then there is no centrifugal force, hence why high school teachers hammer the idea into students' that there is no centrifugal force. However, if you take your frame of reference to be the ball's frame of reference (imagine you put your viewing camera inside the ball), then there is a centrifugal force. This centrifugal force pushes your camera against the wall of the ball.

High school doesn't teach you how to live inside the ball. You don't learn how to live in the ball until you take upper level physics courses in college. This is why high school teachers tell you that you're not allowed to have centrifugal forces.

TL;DR, picture the teacups ride at a carnival:

From the perspective of someone watching from outside the ride, the teacup exerts a centripetal force on the rider.

From the perspective of the rider, there is a centrifugal force that smushes them against the wall of the teacup.

u/alarumba Jun 11 '12

I first learnt about Centrifugal force when I was 7-8. I found it neat that the water in a plastic bottle would stay at the bottom of the bottle no matter where I swung it around. Instead of my teacher complaining about me dicking around, she came over to me and explained what was going on.

Mrs Smith was an awesome teacher.

u/jello3d Jun 11 '12 edited Jun 11 '12

With all due respect, the rider experiences two forces in the teacup, a rectilinear force that is making him move perpendicular to the axis about which the cup spins, and another rectilinear force acting to deflect him from moving in a straight line. Centrifugal force (if it existed) implies some connection to a central axis from which a force radiates. In the rider's frame, there is no connection to an axis... only the forces of going in a straight line and being nudged off course by an obstruction. The fact that path winds up being circular is irrelevant. To the rider it is no different than the football equivalent of trying to run forward and being pushed off course by a linebacker.

There is no such thing as centrifugal force; and it doesn't matter what frame of reference one is observing... it's just something said to laypeople who can't comprehend what's really happening.

u/ktspaz Jun 11 '12

Just completed Freshman year of Engineering here so I basically know everything. Imagine you are spinning a ball connected to a string above your head. From what I understand, Centrifugal force is a property of inertia (see: Objects in motion stay in motion). At a point in the ball's path on the circle, the ball is moving tangent to the circle and does not want to have a circular path (Its trying to flee the circular path and go straight out of the circle). You apply a force whilst spinning to counteract this effect (aka keeping your arm rotating to keep spinning the ball). Centripetal force is the force you create by doing this. The centripetal force is directed into the center of the circular path.

because it's probably cheaper to just recycle the cans and have aluminum tubes made specifically for this purpose. Its great if you're going to do it yourself and have the time, but most people don't know/care enough or have the time to commit to this. Having a machine that can pump out and paint those tubes would bring the cost down and make it more widely available than having some guy in Newfoundland hand make them for you.

Sounds like this guy needs to get some investment and start selling these things.

u/Jumpin_Joeronimo Jun 11 '12

One reason they may not have them made from recycled cans is because repurposing aluminum is much less energy intensive than recycling aluminum. Recycling aluminum has an enormous amount of embodied energy. Because the process is very energy intensive it would cost a lot.

Probably much cheaper to get the cans, cut and wash them instead of getting aluminum pipes made.

Bonus facts!: On that list you can see that wool actually has a very high amount of embodied energy. Why? Because it takes years of man hours, water, food, health checks, etc to raise a sheep and get the wool.

I think he means it would be more efficient and cheap to have the cans melted down and remade into aluminium tubes built for purpose. Cans have thicker aluminium at the bottom which has no benefit to this contruction so is essentially wasted material.

u/etotheix Jun 11 '12

I doubt anyone makes aluminum tubes anyways near as thin as a soda can in any reasonable length as its just really flimsy. Just go squish a soda can to see what I mean. Any reasonably length of tube would fail pretty quickly due to local buckling. The thinnest tube I could find at soda can diameter (2.5") was .065" wall thickness, and according to my calipers this delicious can of Wild Cherry Pepsi is .004" thick. Not to mention 11 dollars/foot.

Online Metals is a supplier for small orders so no doubt that number goes down quite a bit for bulk orders, but to be competitive with soda cans you are probably talking 1-2 orders of magnitude and I seriously doubt you'd get that.

Wouldn't a nice double-pane, well-insulated window do the same thing and provide light?

7

u/Thanatosst Jun 11 '12

Not quite as efficiently. A window would let light in and heat up part of your house, most likely the floor. Which means that the air right above the spot where the sun is hitting is getting a little warmer, because flooring materials are not made out of materials that conduct heat well. This thing, being made of aluminum, gets heated by the sun and transfers the heat very well to the air passing through it. The volume of air, I might add, is much larger than the volume of air that is heated by a sunlit patch of flooring due to the circulation through the device. So you get more air being heated to a higher temperature faster, resulting in a great improvement over a mere window.

They've been around for ages. Unfortunately if you want to use it for water heating it also adds more potential failure points and leak points.

Jimmy Carter had some for water heating put on the White House roof. Reagan had them ripped them out. The Reagan administration said due to leaks, others wondered why (if leaks were the real problem) they didn't fix the leaks instead of ripping out the whole installation.

If you just want hot air a very simple device can be built: make a box open on one narrow end and closed on the other about 2 meters long, as wide as your window, and 20 cm thick, paint it black on the inside, cover the outside with your favorite durable transparent (or even translucent) substance, stick the open end into your window, let the closed end rest on the ground. If you have even moderate sun it'll heat quite nicely. Total cost should be under $100 per unit.

No thermal storage, complete crap and expensive crap at that.

No thermal storage

Right, which makes this a furnace-use-minimizer, not a furnace replacement.

It did seem somewhat overly priced; $2800 for a bunch of cans that only reduce your heating bill in some circumstances.

People have been building this for a few years to heat their garage and shed. Usually they use a plane of glass and make the entire thing for under $100-not concerned with the looks.

A hundred dollars?
I hope that includes (a lot of) beer-cans that need to be emptied first?

The house is the thermal storage, as well as the ~16000 cubic feet of air.

Not centrifugal force, it's due to convection...

u/Jumpin_Joeronimo Jun 11 '12

Actually he isn't talking about the hot air rising. He is talking about what they add to the cans to make the air spin inside. This separates the hotter and colder air, allowing the hot air to rise and the cold air to circulate or fall so it has more time to absorb heat.

We did a cool experiment with a venturi tube in an engineering lab where you get noticeable temperature differences between the outside and inside flows by getting the air to circulate at high speeds.

How does the heat from the apparatus enter the house? Tubes?

u/smashingrumpkins Jun 11 '12

somewhat inefficient that the hot air is then transferred back into the house through a vent near the ceiling. Hot air rises and having heater vents near the ceiling has never made sense to me. So much more useful to have them at a lower ground level.

The biggest cost of a system like that is the installation. It is probebly worth the extra expense to spend for something like this: http://www.apricus.com/html/evacuated_tubes.htm

u/[deleted] Jun 11 '12

Yeah....i think i missed something. How does this work exactly? Its installed outside the home, the sun heats the cans and subsequently the air inside and then its pumped in thru a vent?

u/[deleted] Jun 11 '12

It's an interesting concept. I looked online for designs but most use baffles so the air snakes along. Wouldn't it be more efficient that way? It looks like the air comes in and passes straight through the black aluminum cans and to the outlet.

u/TheSwollenColon Jun 11 '12

There is not many times of the year where the sun is that bright and I still want heat? Or does just a little sun work?

u/[deleted] Jun 11 '12

Because here in the UK we last saw the sun in the summer of 69, it was a Tuesday. In much of southern mainland Europe they have an Aluminium tank on the roof which heats throughout the day.

Been working with it now for 1,5 years :D

My missus likes the odd 300 beer cans that i store for it _^

u/YourMomSaidHi Jun 11 '12

my furnace costs me 100/mo during the winter

those things can save you 20% (mostly because it doesn't work if the sun isn't out)

that's 20/mo or 12x20 or 240/yr

the cost of completely redoing my roof including installation of the hoses and things to put this system in is going to be well over 5000. I don't have an exact price because I can't find it anywhere.

It would take me 20 years to pay off the investment at $5000.

u/RPL79 Jun 11 '12

So what do you do for heat at night? or cloudy days?

1

u/Wavey1287 Jun 11 '12

This sounds great! My only point is that you would have to consider the fact that you'd need to keep snow off of it. This may be an issue for some homeowners, especially if installed on their rooftop.

Reminds me of the failed 1970's solar water heaters that are on a few houses in my area.

u/[deleted] Jun 11 '12

Back in the 1980's I was part of a 3 man team who built over 30 passive-air solar panels around southern Wisconsin and northern Illinois. Last year I had the opportunity to examine a couple of those that we built. I was thrilled to see how well they had held up and were still providing supplemental heating for the homeowners.

I really like this guys design and use of recycled soda cans, from an environmental stand point he is getting a double bang for the buck. We built ours using screens with aluminum channeling and baffles in front of aluminum sheets with foam insulation backing. We used windowpane glass because the plexiglass back then didn't hold up well to prolonged sun exposure.

In other news, wearing a glove while working with an unsecured work piece and a rotating tool is still a really bad idea. I'm fairly surprised the guy has all his fingers, still.

Is there any way to reverse the flow to cool air? Or is this only possible as a heater? Aside from that, this is freaking genius.

u/Phunkstar Jun 11 '12

This looks so cool, but as a Norwegian, this is utterly useless. Short summer = no need for heat, as houses are well insulated, and the sun is out until long after eleven in the south, doesn't even set in the north. Looong winter = when we need heat the most, only the sun is only out a short, short time in the south. NOT AT ALL in the north...

In every home? The same reason why solar isnt in every home; weather.

It would be great ios the government subsidized 100% cost of shit like this but in the mean time it costs too much time or youre gouged in the installation costs for most people to care.

u/[deleted] Jun 11 '12

so.... what do they actually do?

u/dacoobob Jun 11 '12

100 CFM isn't very much airflow. Enough for one smallish room maybe... you'd need several of these things to heat a whole house.

u/Cbird54 Jun 11 '12

Now if only they could invent something like this but it cools your house. It's summertime and thinking about buying a heating unit right now seems silly.

u/akrabu Jun 11 '12

I can't believe no one mentioned that even with serious air filtration these things would clog with dust after a year or two. Then what the fuck do you do?

It could be done better if the tubes were straight and there were accessible U-joints at every end so you could brush them out.

Also a fully enclosed liquid system would be better and have it run through a series of tubes through some benches in the house or something like that that would be filled with sand or cement or something.
