kWh are units of energy, not power. This method is of no interest if it takes years to generate those kwh! Also those films will rust completely off the slide

kWh are units of energy, not power. This method is of no interest if it takes years to generate those kwh! Also those films will rust completely off the slide in a matter of hours. Edit in the case of iron, a 20nm film would fully corrode in about 20 min using a corrosion rate of 0.55mm/y

"Energy is the total amount of work done, and power is how fast you can do it. In other words, power is energy per unit of time. Power is watts. Energy is watt-hours."
