    A common solar thermal panel, a good way to use solat heat. This way saves the energy needed to process aluminium cans -> aluminium bars -> aluminium pipes :-)

      turn off the blower. There is a blower that blows air in through the bottom and as it travels up thruogh the collector, it warms up and re-enters the home through a vent. Turn off the blower and the air flow stops.

    These would blow the top off the market here in NZ! We do solar heating on swimming pools and campervans and we would use them so I’m sure the houses would too!
    Awesome recycling.

    I understand the basic circulation concept but it’s -25C here today. The air would come out of the house 18C-ish I don’t see how the sun could warm the cans faster than they would cool down at these low temps.
