High Humidity Rate Could Generate Electricity

Recent studies show that water on the air could generate electricity on metals expose on a high humid atmosphere.

“ “ Water is a very special molecule. During molecular collisions, it can transfer an electrical charge from one molecule to the other. Through friction, it can build up a kind of static electricity.”….” (Science Daily)

“The scientists conducted a laboratory experiment to determine the voltage between two different metals exposed to high relative humidity, while one is grounded. ”We found that there was no voltage between them when the air is dry.” Prof. Price explains, “But once the relative humidity rose above 60%, a voltage began to develop between the two isolated metal surfaces. When we lowered the humidity level to below 60%,the voltage disappeared. When we carried out the experiment outside in natural conditions, we saw the same results.””(Science Daily)

“They found that materials such as zinc and stainless steel acquired a charge of about one volt.” (Futurism)

The recent studies just only agree with the findings date back on the nineteenth century by an English physicist Michael Faraday that water or water droplets could charge metal surfaces.

“A much more recent study showed that certain metals spontaneously build up an electrical charge when exposed to humidity.” (Science Daily)

“The research led by Prof. Colin Price in collaboration with Prof. Hadas Saaroni and doctoral student Judi Lax, all of TAV [Tel Aviv University]’s Porter School of the Environment and Earth Science is based on the discovery that electricity materializes in the interaction between water molecules and metal surfaces. It was published in Scientific Reports on May 6,2020.” (Science Daily)

The studies also said that in the future the discovery could develop a battery that is charge on a humid air or from water in the air or from water vapor.

The discovery could be included as one of source of energy or source of renewable energy.

“Renewable energy is energy that is collected from renewable resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provide energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.” (Wikipedia)
