A solar heated windshield comprises two matching glass sheets with a hollow interlayer therebetween for inhibiting frost or ice formation on the outer glass sheet by collecting and retaining solar energy within the interlayer. The inner sheet includes a tinted film such that solar energy passing through the windshield is partially deflected into the interlayer to warm the air contained therein. Deflected solar energy may also impinge on or be deflected into a reservoir containing a heat retentive and conductive liquid such as propylene glycol. Air within the interlayer will be warmed repetitively by the heated glycol through the fluid motion of convection. Heat may be transferred by convection to air throughout the interlayer or only to specifically focused areas.

[ Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is as follows:] [1.] A solar heated vehicle windshield comprising:a first plate of glass having a first exterior surface for facing the ambient air outside the vehicle and a second interior surface;a second plate of glass having a first surface for facing said interior surface of said first plate and a second surface for facing an interior of the vehicle;an interlayer of air space between said first and second plates;means for maintaining said first and second plates in said facing relationship with said interlayer of air therebetween;a reservoir;a heat exchange fluid in said reservoir; anda plurality of spaced-apart channels, each channel attached to said reservoir and having a bore in communication with a corresponding slot in an upper wall of said reservoir, each said channel extending into said interlayer and having a closed top, said fluid capable of a heat exchange with air in said channels when solar energy from the ambient air passes through said first plate and into said interlayer for a heat exchange with said air in said interlayer.
