Vortex engines exploit atmospheric convection: heated air at ground level rises and spins, creating a vortex that can drive turbines. The concept—proposed by Louis Michaud and others—uses waste heat (e.g., from industrial processes) or solar energy to create a controlled convective column. Power generation would occur from the vortex flow. Research and small-scale experiments have been conducted; commercial deployment remains speculative.
Alternative power generation seeks novel approaches to harnessing thermal gradients. Vortex engines offer a conceptual pathway using low-grade heat. Challenges include scaling, control of vortex stability, and competition from established technologies. Research remains limited; vortex engines represent an exploratory concept rather than a near-term technology.
