72157609496730358 this is a slide show of my project,the 180 deg f,was with fan in picture.I have changed to a 120cfm bath exaust fan,now operating temp is between 110-130 deg f.feel free to make comments ,good or bad.  plz click slide show.

ok,this is my panel,it is covered with aluminum house facia.

it is on my garage,you may notice the chiminey,thats for my

wood burning stove.gets cold here in wisconsin US.the other

pipe is for martin bird house.

Hi

An image upload test (firefox browser)

I may use this blower for a large fence collector,its just gathering dust in the shed. It doesn`t have a great quantity of airflow but should handle the static pressure easily.

The specification is 400m3/hr @750Pa ,  340m3/hr @2000Pa and zero flow @ 5600Pa.

It draws 550w, so the panel must generate a lot of heat to make it worthwhile

Best Regards

Here is a picture of my greenhouse.

Here is an early test of inflated pillows. The two outer skins have dotted lines, a  third layer of much thinner film is fitted inside the pillow to equalise the pressure between the two air cavities. The pillow is inflated to 200-250Pa but can be increased to 400Pa for snow or heavy winds.  The adjustable (50-500Pa) differential pressure switch controls the pillow pressure.

It has succeeded.

… is just a home made (turned) plastic hand protector. It protect your fingers not to cut off while drilling the holes to cans.

The outside diameter an avarege beer can is 65mm so the inside of the plastic ring must be at least 66mm. (I missed from drawing

This protector is fit both side of beer can. The upper ring plate is a simple plexi plate, the other one is made some kind of other plastic.

(all measures in mm)

My collector is 2m2 size 1m x 2m
15 tubes x 10cans (150) + divider & collecor element.
The spliceing of cans I  made with balck silicon based glue. It resistant up to 200 C heat.  After drying it still flexible.

Building the housing:

I bought 140mm wide aluminium adverusment billboard aluminium elements.

After a few hours workin i got the frame of the collector. My son was realy handfull of srewing

This temperature difference switcer (i hade to mount myself) would operate the whole system.

Here is my dividers-collectors. (I build a solar heater for my father too

.

Some picture of mounting the housing:

First step after collecting some beer cans was the cut out of both ends of cans. It takes me about 3hr with this equipmnet.

Special cutter for driller: (one of my turner friend made it to me)

Plastic “thing” to protect my hands while drilling

Second step: to make propellers (now I know thats not necessary) to revolve the air more afficiently in the beer-can-tubes
