Just a quick postscript for @uncleoscy -- Have a look at this PF Insights article about PMMs to get a better understanding for why they cannot work, and why we do not waste time discussing them here:uncleoscy said:
A self-powered fan is a device that generates its own energy to operate, typically using renewable energy sources like solar, wind, or kinetic energy. It eliminates the need for an external power source, such as electricity from a wall outlet or batteries.
A fan can be self-powered by incorporating energy-harvesting technologies, such as solar panels, which convert sunlight into electricity, or using small wind turbines that harness wind energy. Additionally, kinetic energy from movement can be captured using piezoelectric materials or small generators.
Yes, there are several examples of self-powered fans on the market. Some are designed to work with solar panels, while others utilize thermoelectric generators that convert temperature differences into electricity. Additionally, there are fans that use small wind turbines to generate power in outdoor settings.
The main advantages of self-powered fans include energy independence, reduced electricity costs, and environmental benefits from using renewable energy sources. They can be particularly useful in remote areas where access to the electrical grid is limited or in situations where reducing energy consumption is a priority.
Challenges in creating a self-powered fan include ensuring that the energy-harvesting technology is efficient enough to meet the fan's power requirements, optimizing the design for maximum energy capture, and maintaining functionality in varying environmental conditions. Additionally, the initial cost of developing and producing such devices can be a barrier to widespread adoption.
