to save money for other things like paying your mortgage or refinancing your home. Hope this helps:-) Note: Look T THE VIDEO RESPONSES THEY ARE VERY GOOD! This is a prototype easy to build rooftop forced air heater that produces 45 degree increases at a high CFM CFPM rate. This one is made out of cardboard. A real one can be made out of weather proof material COROPLAST. www.greenpowerscience.com … DIY SOLAR ROOF HEATER SUN GREEN ALTERNATIVE FORCED AIR CORRUGATED CARDBOARD BOXES BUBBLE MAILERS …
. The day that I tested this panel it was hazy and a little overcast. the following day my results proved to be far better. At 20F clear skies with a 15 mph wind I was getting as much as a 56F degree increase in temp (71F intake and 127F at the exit port) constant. By 1:30 the interior of my building was 75.4F when I shut it off. I was burning up.. ;0) I have a few ideas for another blower system. I’ll post that video when I get finished… Thanks again.

well i just have to point somethin out, the shop vac will make heat itself and blow it out so you gotta take that in concideration

The US uses 3.3 terriwatts of power. How many terriwatts of power could I buy for $819 billlion?

I wonder if if a mirror reflection set up to a brick center piece in a house would work out…(brick chimney dual sided, center of house-

how fast do they cool when the sun goes down i wonder- def some great stuff man- get the world off the grid man!

Besides air blowing into your van from the open hatch… is also the van’s exhaust. Be careful.

A shop vac is going to consume much more electricity than what you are saving. The vacuum was also probably generating some of the heat too. I would have used ABS/PVC type pipe on the ends to better distribute the air, and set the array vertically in order to try to get gravity to get the air moving. No moving parts, no noise, no power consumed. Cool video.

Who needs a heater when its over 80 degrees outside anyway?
Report Spam/Abuse
I didn’t get the purpose Winter time it would be good for sunny afternoons, but that’s it. My heater only comes on at night or on cloudy winter days. Exactly when this would be needed, thus not useful. Coroplast breaks down in the sun after a couple months too.

Coroplast lasts about 3 years if you use a flat black enamel spray. Many people have cold days with the sun out. Not a perfect solution but worth the effort. Works for water too.

Coroplast the same material used in construction sites to protect floor and wall surfaces?Its pretty tough.I have been watching some videos about ‘solar can heaters’ and I was thinking, you could use this material as a backing and take advantage of the heat it can pass up the channels in addition to your cans,how about narrow copper tubing up the channels?Im in the UK i plan to build something along that line -if i can save ANY fuel bill even on odd days I will be very happy.

The point is the amount of energy you can get from the sun. When your power is out for three weeks in the winter please make a video of your “heater”. It will really be cool to watch, once the power is back on for you to upload…….. no pun………..I am still using my solar panel and it has cut my heating way down….265watts vs 3000watts you do the math.

in south america are many poor areas in the andes were is cold but sunny or enough sun light for long periods of the year .totally useful here.
Report Spam/Abuse
The problem is storing hot air. Where does it go? During the the sunny afternoons it would useful. I’ll have to try it next winter with some left over political coroplast signs I always see polluting the enviroment.. My windows face south and west. It can be in the 50s here and the sun will warm up my house. Anything colder and I need a heater. I’ll try it next winter. Thanks

hi, everything great. i would do 2 things different:
1st measure air temperature in and out, because vacum cleaner also heats air ~10 degrees i woud guess.
2 for better air circulation balancing i would do a plastic pipipe collector. Cut pipe like (C——) put silion to seal. Now pipe of 50mm would be perfect to even the flow.
i know , because i am HVAC engineer my self
i give you my personal 1000% of aprooval because people like you never stops exploring limits. keep it like that

I would have done the intake in bottom left corner and the exhaust at the top right corner, so all possible path from intake to exhaust are the same lenght, so you use all the surface more efficiently.
with holes in the middle you only use the middle of the board
Report Spam/Abuse
This Sounds like a nice system, but a few things.
(1) Will it work in the winter?
(2) You probably should place glass over it to increase the Available heat.
(3) U said more then one intake, but perhaps more then one Exit would do good, too.
(4) What about snow?
Keep running with your Serendipity, It sounds useful.

what was that flash of a sign at 1540 – 1550?? brain washing, subliminal messeging?. not done that well. oh the heating idea is good, so simple but brillinant

i see it it says vote for DAN LOL i saw it!!.

It was originally longer. If you notice the sound gets off at the end. Videos longer than ten minutes had an upload issue back then. It came out as a flash, unintended subliminal message. Wish I would have put “Give Dan Money”
Since the video got featured I just kept this one up.
Thanks for noticing.
