Last crawled date: 1 year, 11 months ago

Easy to build by any unskilled person, buy a 1 meter wide and 2 meters long plywood sheet, 2 lumber pieces large 15 cm and long 2 meters for the sides and 4 lumber pieces large 25 cm and long 1 meter.

The four short pieces cut them to have one side following the arc of a circle, that shall be the side towards the plexiglass, and at two of them drill holes of 61 Cm diameter one next to the other, they should fit 15 of them.
Collect some 250 cola aluminum cans of 330 ml (or 200 of 500 ml) and eliminate the bottoms and the tops, the part inside the ring, so that the rings can stay and alienate the cans, than build pipes of 16 330 ml cans glued together with red silicone or similar heat resistant material, having the cans alineated in an angular profile and pressed by some weight to dry. Build 15 pipes of 16 330 ml cans each, than paint them black, preferably non shining.

Once you have the pipes insert them in the 2 lumber heads with holes, than build the box around the plywood with the other 4, place some insulation on the plywood and insert the cans with their holder in the box.

Seal well all the wood parts and the wood to cans contacts.

Place a 3 mm thick plexiglass on top of the thing with silicone on the plexiglass to wood contact, and screw fix it well, drill a hole in a lateral lumber piece to fit in a non return rubber valve for vacuuming, than vacuum the inside to insulate the cans.

Now all the air passing through the cans exposed to sun even in freezing winter will go in say at 15 degrees Celsius from your floor level and go out at over 50 Celsius in cloudy days and over 80 in sunny days, and in the summer they will exhaust 200 Celsius, just fit to cook with the hot air in an oven.
