Energy conversion using metal nanolayers.
Scientists the effect of converting the kinetic energy of the flow of salt water in the ultra-thin layer (approximately 10-30 nm) of metal oxide formed on the surface of metals (iron, vanadium and Nickel), into electrical energy.
Energy conversion using metal nanolayers:
Scientists have discovered the electrokinetic effect – the effect of converting the kinetic energy of the flow of salt water in the ultra-thin layer (approximately 10-30 nm) of metal oxideformed on the surface of metal (iron, vanadium and Nickel), into electrical energy. Earlier, a similar effect was observed in films of graphene at course on it of salt water.
The conversion efficiency of energy is about 30 %.
One square centimeter of a thin layer of metal oxide is able to generate several tens of millivolts and a few microamperes of electrical energy. Accordingly, the sheet of metalcoated with a thin layer of oxide, an area of 10 m2 can generate several kilowatts of electricity per hour.
