Bio-Electricity

Though people might not usually think this way, we are all electrical beings. However, the electricity to run our brains and muscles comes from what we eat rather than an electrical generating station somewhere. I was wondering if in the future it might be helpful to have the capacity to have the electrical needs of a human body be generated by electrical means other than food. Though it is true the nutrients of the food we eat allow the cells in our bodies to live and to regenerate themselves, it is also true that the electricity in the body that operates nerves and brain cells could be generated from another source. So, for example, one might have D cell battery or even a couple of double AA batteries with the right converter to convert the DC electricity down to a useful voltage for a human body and likely greatly reduce how much food a person might need to consume to feed the cells of their bodies. Or since solar cells are basically a lot like photosynthesis in plants one could have solar cells built into their clothing so they would have electricity for their nerves and muscles and brain cells to operate effectively even if they didn't have enough food to eat that day.

One of the reasons that I'm beginning to think this way is when I imagine how the world will be changed by Global Climate change it is possible that growing food out in the open might be a problem most places because rains likely will tend to be more sporadic and torrential when they happen and winds will also tend to be much more extreme and higher in velocity than now. So, unless food is grown under protective glass or plastic when winds are strong it might be difficult to grow unless people are growing things like sprouts or tomato plants in their windowsills of their kitchens and bedrooms and living rooms all around the world and inside the protection of their (by then much reinforced windows) that can withstand 100 mph winds and storms or more by then.

However, even then winds can generate electricity and so can the sun, so both these sources could be used to recharge batteries which might greatly reduce food consumption worldwide. Because then you would only need enough good food to rebuild and heal the cells of your body, but your electrical needs might be sustained directly through solar cells or wind power converted into electricity.
