Earth Day vertical axis wind turbine homemade diy start to finish VAWT
Переглядів 27 тис.13 років тому
I make a VAWT from start to finish with wings that extend 8 feet from the axis. This VAWT is fitted with small "sails" for testing. VAWT's weight is made from at least 85% recyclables.

This shows how to perfectly roll an edge of sheet metal. See www.steelsail.com for details.
This is why there is so much chemtrails in our skies! We are using to much free solar energy for some guys...
Building a few small solar heaters for my farm animals. It will be rarely used here in Louisiana, but cold snaps do happen, and i really don't like heat lamps around animal bedding.
Use mirror mounts to attach the windows (like the ones yo use to attach a 4' mirror to a door for example). Less chance of breaking things and easier to maintain or replace the windows. Is a permit needed for those?
If aluminum is a great heat conductor . Couldn't you save money by just using aluminum cans or any other recyclable material?
Imagine posting a video then checking it a few years later and there are hundreds of comments telling you how to do it better.
How About Removing the whole unit, and pull the curtains away while the sunshine into the room? Don't Put Anything in front of the energy flow
That does it not help thew the night
old storm doors or used windows are your friend to build these. glass enclosed in an edge already ? two that match? 4? great.
Bonjour le tuyau dans le four ne faut il pas qu'il soit noir svp
This is exactly what I've been wanting to do
here in 2022: $50? thats for 3 bolts sir...
you're the first person I've come across that doesn't use cans and didn't cut threw their house thank you so much for this video
Open the window instead fully
I tend more to this design becouse you the air doesn't get in contact with the paint
$50 the timber would cost more than that
Why is your website for sale? Does that mean this does not work? I am being very respectful. I am just in search of truth. Thank you for being kind to answer.
Seriously have you ever take temperature measure in/out during winter day... it seem really a bad idea! I guess the air come back colder than the house air🤣🤣🤣
I would like to see some temperature measurements. House temperature or temperature going into the unit and temperature exiting from the unit? Air flow?
why not on the roof? then it's out of side. great idea..I am going to try this..
Couldn't this be built in the window? Seems like we wouldn't loose so much heat in the process. I really love this with the dry vent pipe! Saving cans for this endeavor is taking far too long.
I'm building something similar to this design. Items I used are: 36×72 frame from 2x6s backed with 3/4 in ply .5 inch insulation sheet 24' black aluminum flex duct 90 degree plastic elbows 2-8' flex duct for in and out piping to house 4" inline duct motor with speed control. 2 glass sheets Everything is black in the box. I plan on 2-45 degree mirrors to help deflect the sun in to max out exposure as well. I'll eventually convert to solar powered blower, just need a deep cycle battery to hook to a large power converter I got for free. Hopefully I'll get a video up showing specs and temps. It will be piped through a window with blower pumping up, while intake line will feed closer to the floor.
Looks great! I designed a new model for DIYers without wood, glass or off-gassing materials. I'd like you to see it. ua-cam.com/video/VhhJt-ZzRwI/v-deo.html
Great place to learn how to make it yourself much much cheaper. Just google for 'Avasva' :)
What I do to warm my room is open the curtains and let the sun in. Other than that it's cold for the night time.
no data, temperature readings, etc. I would assume it was a fail?
I know your wife discouraged you from putting in a realistic permanent hole like the kind used for a dryer vent, but think it really would look a thousand times better if the pipe came of the furnace and turned directly through the wall. Those return lines could be plumbed and buried the multiple other sides of the house . This would cause the heat to travel toward those other rooms.
works all summer long
send a bunch of there to Texas
I have a better one. Use the same type box, but make a hole in the top and the bottom of the back panel. The bottom hole goes through the rim joist and into the basement. The top hole goes where ever you like. You need a small fan, about the size used on a desktop computer, and a thermostat. Set the thermostat at about 90 degrees and couple it to the fan. When the sun hits the box, even on a very cold day, it will take less than 20 minutes for the fan to start. If you have a stinky, moldy basement, this is not a good idea. But if it is reasonably clean, you will have a good, nearly free source of heat while the sun shines. This also helps to remove moisture from the basement. Everybody should have one of these.
Add fire brick to this design and you have a solar mass heater!
This could be used to preheat the air intake of home furnaces in the north.
so wheres the proof if you dont show how much heat it intakes in the house
Honey? Can you turn on the solar furnace? The sun's nice and blistering hot out.
What happens at night?
A note to anyone who wants to try this: The return air line needs to be as large as the hot air line. Both have to be insulated. The collector box needs to be insulated. Otherwise you’ll just be collecting heat and radiating it back into the outside air.
That's what I was thinking, shouldn't be insulted inside the box but everything outside should be
This is a pipe dream!
Sure would work good in summer time in the winter time just cut another hole in the wall and put in another window...
Those pipes should be black not silver
danger Will Robinson!
No. Can't convince me. Poor design to begin with.

I'd rather cut a hole in the side of the house for the pipe and the 2 small hoses than lose a window.
Let's do a little back of the envelope calculation using some kindergarten thermodynamics. Your heat captured, "Q" equals the mass flow rate of your working fluid times its specific heat times the change in temperature. Q=m*C*deltaT. 37 cfm,(which is a VERY optimistic estimate for one of those fans) is approximately 2.5 lbs/min or 150 lbs/hour. The specific heat of air is .24Btus/lb so with a 25 degree rise in temperature you are capturing a whopping 900 Btu/hr or the equivalent of about 264 Watts. To put that in perspective, you would get as much heat in your house from three 75W light bulbs, a laptop computer, or a TV set. At $.15/kWhr that's "THEORETICALLY" about 4 cents of energy per hour of operation. Lets say you can get this for an average of 4 hours a day, about 60 days a year, (again, an extremely optimistic estimate for Oregon), you COULD save $9.5/year so that's more like a 5-6 year pay back. And this doesn't even take into account the heat you will lose by compromising the air tight integrity of your window which would likely make this a net energy loss from your building envelope. I am a huge proponent of solar energy applications, especially homegrown applications, but this is little more than a fun experiment with no practical value. Capt. Carter, www.shipofimagination.com
Its -40 here now, that wont cut it !
-21 here lol
ive been doing hvac for over 15 years and if your heating a small closet that may slightly work. get ductulator app on your phone and it'll help you figure out what all you need to make this actually work. ground temp is also constant.
Seem legit and useful.... I’d love to see some temperature readings, intake air, exhausted air, outside temp., temp at the glasses, etc....
The glass will crack due to thermal stress.
If so, why our window glasses doesn’t crack the same way? They are also exposed to the same sun...
Check out beer can solar convection vids, a few guys do do thermometer readings.
@@newsnowadirondacksredux360 Not necessarily. it looks like 1/8 inch glass with jmold around it. No difference than what some have in their windows these days. single pane or double pane. I'm wondering if the glass is tempered.
POORLY DESIGNED
Hope everyone realizes the tubing should be black to absorb the most heat from the sun. The reflective tubing will reflect most of the heat. Why do you think the best windshield heat guards are reflective. Why do you think the same thing used to heat water has black tubing? Good execution but missed one major thing. He could also magnify the heat by using a parabolic lense to focus the sun light.
I just stay in the green house :D
Fantastic. Cover a football field with those and your house'll be lukewarn 3 hours a day... on sunny days.
