SOLAR FURNACE HEAT COLLECTOR FREE ENERGY HOW TO TOTAL COST $100

[DChatc]

This would actually be simpler than most would think, it just requires lots of piping and mirrors (and even some lenses to intensify the lightflow).

Just paint it black then place the glass sheet over it. The Sun will heat it up and will soon dry and harden.

Foam is a bad ideal when to hot or melts the fumes are toxic .Check out duct board ,check out these bilge blowers 12volt 3inch or 4inch amazon.com PS:Like your design,Just being a caring person

[thanos1989]

Good job, was nice and clever to reduce emissions of your heating system !

But I think the insulating material used is dangerous because it releases toxic fumes when overheated. We recommend you to use, on your next manufacturing, fiberglass or stonewool with aluminum foil, which withstand high temperatures and does not release toxic gases. Careful though the dust in their use. I hope I helped and sorry for my English, but I'm from Greece.

[themassinfluence]

don't use pl 400 with it degrades the foam. use pl 300 instead.

[modernblacksmith]

@themassinfluence thanks buddy!

[modernblacksmith]

@themassinfluence thanks buddy!

[themassinfluence]

@modernblacksmith the pl400 has similar solvents to the ones you mention in the barbeque paint @7:48

[oatstao]

Pussies need mitres anyways..hahah..and Pussies don't work well in the winter.. good job ;)

[Biervrienden]

Great video! I'm building one myself now

[terryhesticles1000]

dark, dull and rough = best heat absorption.

[guicapone2]

will this work in winters? also.. if you know thing or to about solar water heater..do they work in winters also?

[modernblacksmith]

@guicapone2 well, no matter what type of solar power you use none work nearly as well in the winter. when I did the temp reading it was -10c that day

[ctconnor9]

@modernblacksmith hot air panels will produce more heat if baffles are installed under the sheet metal to increace the air speed.

[water4fuelh20]

@modernblacksmith I disagree, Its all in the way the heater is built and made. I've been doing this for many years and the use of fiberglass house insulations is the best way to go with a heater off the house. The lighter the aluminum the better the heater performs. My 4x8 heaters have performed great at temps of 130 Plus and this was 0-5 deg outside temps. And this is using a car hvac blower motor. Ideally you want to be down around 110 blowing in with adjustable fan rates.

[dunkdriver1972]

NICE VIDEO. england we have an insulation product called kingspan/recticel. it's a foil covered hard, light foam that comes in 8x4 foot sheets. ideal for insulating the box. also have you thought about sticking an old radiator (for gas central heating system) in there and heating water with it?

This is why the internet is vital to the human condition as a whole...the open sharing of information that elevates all human beings to a more significant level instead of eschewing information allowing others to suffer due to lack of awareness and knowledge or subjecting themselves to others who know better, but do not care about the environment which we all inhabit...purely for the sake of the acquisition of some monetary value of no real esteemable worth...pity. Thank God for the Internet.

[magna59]

I dont think you need the aluminium sheet, you are not trying to transmit the heat through to water for example or in the case of the sola can items into the air flow inside the can tube, you are just tring to radiate it back into the air. If the foam can take the temperature, I think it should work equally as well if the foam is painted black, the surface should shed the heat back into the air as it passes over the black surface.

[bill65761]

Close, no kewpie doll. The cut is called a "rabbet" or "dado", not a 'rabbit' or 'dato'. Yeah, that's a quibble .... like the trivial difference between "lighting" and "lightning".

[futureisnow1]

Good job, best vid I saw so far! ! the only thing I wonder is, the styrofoam , is it toxic when heated by the sun, since the heat go into your house?

[wrusst]

I know very little about these unit but im trying to lean as much as possible on the inlet side would it not be better to have the exchanger/collector all the way over the inlet and a little bit more over the outlet for a bigger surface area?. Im thinking about building you design but with a n or s shape under the collector so the air has more time to heat up bit like the solar sponge?

[skaterincanada]

i just wanted to let you know that the cut in the 2x4 at the begining is called a rabbit cut, other may call it a dato edge

[215alessio]

Hello, thanks for the idea, this one is quicker to buld as the soda cans type

but is it more efficient to let the air flow only on the backside of the collectorpannel like shown in the film?

[modernblacksmith]

@215alessio it flows on both sides. it worked very well, I have a new house now and I will be building another better version soon.

[215alessio]

@modernblacksmith

Thank you very much for the useful information, I will buld one over some month. this type much faster to buld than the sodacans, so I can buld a larger one than I was planning for the sodacantype.

That means it will have more 'heat collection' than the smaller one with sodacans even they say that they are a bit more efficient.

I am shure this one will be "overall" more efficient so thanks again.

In Europe every Kilowat hour costs 23 eurocents ~ 30 USDcent

[s4a4v4y]

quetion to anybody...would double pane inpead the process, is single pane more suited for this project or does double pane allow more heat in

[modernblacksmith]

@s4a4v4y seems to me the double pane would work better. it would put out the heat and if you touched the outside of the glass it was cold. so not much loss. (this is only recommended if you can find one for free or cheap.

[1thatisilluminated]

@s4a4v4y Double pane would be much better because the sun heats the metal and the heat stays in the unit rather than be cooled by the cold air outside touching the glass.

[hubbyswife]

I'm a wood butcher too, but I still like to work with it:o)

[pinetar100]

nice

[adam3176]

thanks for the vid... Yea im not a wood worker either. and i make good speaker boxes... So im sure i could pull one of these off..

[laithnour]

hey is that an ambulance you're working out of the back of?

[modernblacksmith]

@laithnour no that's the deathmobile (it used to be a mail truck)

[comicfan21]

what exactly does this do? (I'm unfamiliar with solar collector types)

[modernblacksmith]

@comicfan21 heats up on the inside from the sun and then you pump the heat into your house.

[jimprice09]

How many hours a day you have hot air ?

[215alessio]

@jimprice09

if you live in scandinavia, it depends on the season LOL

[modernblacksmith]

@jimprice09 say it was sunny all day....then about four to six hours of very hot air and a couple hours of relatively warm air. (but it's all free that's the point)

[humourcar]

This looks much easier than the beer can unit.

I wonder how it compares. Looks like it would be a lower profile but would it generate as much heat?

[modernblacksmith]

@humourcar I would say if it was working less efficient then it would at the most be 90% of the cansolair and I could build 40 of these units for the same money!

[robwiley01]

After watching about 50 vids on how to do this, yours seems to be as very good, fast & economic to create too. So, can you post some real numbers on the befor/after results inside the house from using it and the volume of space it's heating?

Thx

[modernblacksmith]

@robwiley01 sorry but shortly after building them we sold the house. I plan on building a different type of unit soon.....

[modernblacksmith]

@robwiley01 the simplest way to to think about this is imagine you just put in a window this size into your south facing wall the sun that would come into your window and heat the room is about the same. You CANNOT get more heat than that, the sun only has so much to offer. one 4x8 box per 200 sq ft, would be ideal....

[kidjr27]

How do you get the warm air to flow out?

[modernblacksmith]

@kidjr27 small 110volt duct fan it only uses .2 amps

[lsmith254]

Great job! Yours is a faster way than the one I am working on now...I have to make the top manifold next, and I will be ready to paint and install it. Made mine with soda and beer cans; found a really fast way to assemble them without using so much caulk. Will put up videos this later this week.

[viking1au]

1:Is a Rebate. Don't understand the difference between Styrofoam & rigid foam.---- Not convinced it is as efficient as it could possibly be; however; one of the better hands on "how to" features on this subject.-- 10 points for effort.

[jihadacadien]

and this works.....sweet! and thanks a lot fellow east coaster!

[froshmasta]

Good job on the solar air heater. I'm thinking about making one as well and I'm glad to see someone else in NS is using them.

[water4fuelh20]

First 5 stars for making your video in such cold weather.

Second great job! I'm in the process of building one myself using glass. But for testing i'm not going to mount to the house. i will make a window box and run the ducting in that way.

Thanks for sharing.

[mikedolson]

hey do you think you could use huge freshnel lenses on your set up?

[modernblacksmith]

I think that defeats the purpose, glass is the way to go, basiclally you're making a greenhouse and sucking the air out...

[excalibur440]

Did you get your solar panel mounted on your house? Just wondering how it worked out. thanks for the video.

[modernblacksmith]

I did and it works fine, I think I would use 6 inch ducting next time.....

[cycloneCJproducts]

@modernblacksmith well lets see a video of it mounted and working in the house??? PLEASE............  :)

[modernblacksmith]

@cycloneCJproducts I would but only a few months after I built it the house was sold.....but I will soon be building a new furnace but MUCH larger for the new house....
