Notes:

  • Safe, DIY, common material chemistry
  • 6 cells made 2V - with 2 mA for 350 continuous hours
  • 600 mAh at about 2V
  • 2V x 2 mA is 4 mW
  • Cost at wholesale prices: 10 cents/watt-hr or $100/kWhr. Which is lower than Lithium Ion, and Lithium Ion should reach this price in 2023 [1]
  • Experiment cost - about $100 for 1Ah, or $100/Whr (1000x wholesale price)
