I would like to know if it may be possible for a life form to live solely on electricity.
Question Date: 2002-05-28
Answer 1:

Boy, that's a humdinger of a question (by the way, humdinger means that it's a beautiful question)....

Can life live solely on electricity. Well, let's start with the basics. What is electricity? Electricity is the flow of electrons from a source (usually called the anode) to the destination (a cathode). Think of electricity as a river of electrons. And what are electrons? Well, I'll let you look that one up.

So, the next question is "what is life", right? If we know what life is, and we know what electricity is, than maybe we can figure out if electricity can support life. But....the question of "what is life" is a very tough one.

All life grows, reproduces, and dies. All life needs to feed on something. Life as we know it, you and me and birds and dolphins and cows, all feed on chemical energy. When you eat, your body breaks down the food into chemicals and uses it for energy and building blocks to make new bones and skin and hair, etc. So, what's the answer? I think that electricity could provide energy for life but not the building blocks. So, I guess I do not believe that life can exist solely on electricity.

Well, what do you think? I hope you will think about it some more and if you have any more questions or ideas, write to us and share them. You might think of something that I have not!
