Imagine powering your phone with carbon dioxide

  > The coated flakes soak carbon dioxide, and produce positively and negatively charged particles. The positive ions are big and stay confined in the gel, while the much small negative ions move through the hydrogel channels, producing electricity. From time to time, you must regenerate the "coated flakes" or change them, so it's like a AAA batery. It has energy stored in a strange way, and the energy is released with the CO2. So instead of a lithium ion rechargable battery, you get a worse battery.
