Solar energy after the sun sets

I am a new member but I did not see this idea proposed yet. Using a highly efficient air compressor to compress ambient air which also compresses the solar heat which is in turn used to heat a sterling engine. The sterling engine turns the compressor (initially this process will need a jump start) and then the compressed air is used to spin an electric generator. But because the heat has been removed from the compresses air it is used to absorb heat from the other side of the sterling engine thus improving its efficiency. The output would be free electricity and water that fell out of the air when compressed. The energy that powers this process is pure solar so nothing magic is going on. Any thoughts?
