      Hello,
      very good text! Just, I found a “wrong fact” in the Conclusion. I’ve got a large “scientific” calculator and that´s got the power consumption listed on the back: 0,002 W, so 2 mW. A normal calculator probably uses less than half of that. A wrist watch, I would assume, uses about 0,01W. A good 2W example is a (slowish) phone charger. It also would be good to mention that a two-watt cell is around 150cm² (or 10 by 15cm), because the size is what makes the most difference in wattage. Please correct those facts. I really like the rest of it!
