To inflate the tubular housing member 20, at least one gas passageway operatively extends from the gas conducting conduit into the interior volume of the housing member. If the energy collecting panel 30 is operatively sealed within the interior of the housing member to divide the interior into two separate portions, a passageway must extend from the gas conducting conduit to each of the separate interior volume portions. Shown in FIGS. 1 and 2, a passageway 46 extends through the second panel 34 from the conduit portion 38a to allow inflation of a front chamber 48 between the second panel and the front wall portion 22 of the housing member 20. A second passageway 50 extends through the energy collecting panel 30 from the conduit portion 38a to allow inflation of a rear chamber 52 intermediate the rear wall portion 24 and the energy collecting panel. A supply of pressurized gas is provided in the front and rear chambers 48 and 50 respectively from the flow of pressurized gas flowing through the gas conducting conduit. Gas flows into the front and rear chambers until they are inflated and thereafter the gas flow terminates and the gas pressure within the front and rear chambers main |
