This invention describes a system that uses wind to turn a windmill. As the windmill spins, it pushes air upwards into an air chamber. A light-focusing wall above this chamber concentrates sunlight to heat the air, which is then jetted out to further rotate the windmill. The system also includes a filter to remove carbon dioxide and other impurities from the air.
Why it matters: Filed before significant advancements in materials for passive solar heating and carbon dioxide capture. The integration of wind and solar thermal energy for kinetic output has become more relevant with hybrid renewable energy system development.
